The present study was designed to record the distribution of ground dwelling spider genera among mustard crop at Okara district. Sampling was made from Brassica compestris crop through pitfall traps. Equal number of traps were placed in three rows e.g. along the boundary, middle of the field and centre of the field. Each trap was filled with mixture solution of alcohol and glycerin (70:30%) along with few drops of kerosene oil. After 5 days interval sample traps was collected and spider specimens were washed with distilled water and permanently stored in labeled glass vials, and brought into the Pest Control Laboratory, Department of Zoology, Wildlife and Fisheries, University of Agriculture, Faisalabad. Thereafter, each spider specimen was identified according to the taxonomic material and internet source. Identified data was analyzed statistically to quantify their spatial distribution. Maximum spatial distribution of spider population was documented in middle transect than boundary and centre of the mustard crop. It was also observed that temperature, humidity and prey availability were the major factors that effecting the spider population. Population variations were recorded during the months of February, March and April in 2015, due to rise of temperature, decrease of humidity and availability of prey. Conclusively, spiders have some correlation with suitable local conditions or habitat. More over, spiders are cost effective, functionally significant and play important role in regulating decomposer population.

Beetles in Selected Barangays of Catarman, Northern Samar, Philippinesijtsrd
This initial research effort was conducted to identify the beetle species in five selected barangays of Catarman, Northern Samar, and describe the environmental factors that affect the presence of beetles in the study area. It used the descriptive method of research, with the purposive sampling technique as the sampling procedure utilized.Due to limitations of the researcher, a total of only seventeen 17 beetle species, belonging to eleven 11 families, were found present in different sampling sites. The most abundant of the beetle species individual was Harmonia axyridis, constituting 76.14 of the total number of beetles in the study area, while the least abundant were Alaus sp., and Diphucephala sp., each with only one 1 individual present, accounting for a relative abundance of only 0.46 . The air and soil temperature range between 27oC to 29oC. Grasses, trees, shrubs, and herbs were the common vegetation present in the study sites where beetles were found. This implies that environmental factors were conducive for the beetles to thrive in the area. The presence of different beetle species indicates the study area has a diverse beetle fauna, albeit it is only a small fraction of the total beetle species listed in the country. It is imperative that conservation efforts should be strengthened by the LGU in order to conserve not only the beetle population in the study area, but other organisms, both flora and fauna, as well.

New pulse crops varieties more productive as medics should be made available to breeders located in semi-arid region of Algeria. So, and through two years of testing, pods yield and seeds production of twenty populations belonging to species M.intertexta , M.ciliaris, M.polymorpha , M.Truncatula and an introduced population M.muricoleptis is an Australian cultivar (Jemalong) are appreciated.Pods’ yields of year 2013 vary between 78,66g/m² with poly27 and 3637,33g/m² with I107. Values of the second essay (2015) are different, they vary between 40,89g /m² with Poly236 and 464,36 g/m² with I11.The cultivar Jemalong offers a yield of 172,4 g/m². The corresponding seed yields also show a low production in year 2015. The ratio leaf / stem varies between 1,03 and 5. The average of yields in dry matter of 27 populations in 2013 was of 457,79g/m2 against 127,41 g/m² in 18 populations in 2015. Jemalong cultivar records a yield of 12,8g/m². For the same dose of seed, number of plants by square meter varies between 44 and 112. Number of stems by square meter varies between 136 in C204 and 420 in I52..The average width of population’s ramifications varies between 13cm in Tr334 and 44 cm in I52, The Jemalong cultivar offers an average of 17cm. So, production results of medicks depend of weather conditions in littoral zone of lower altitude than 600-700m. In steppe zones, we recommend to make tests in situ with these same populations.

Birds of Pambujan, Northern Samar, Philippinesijtsrd
This assessment was specifically carried out to identify the avian species present in the study area, describe its distribution, determine its frequency, ascertain their conservation status, and enumerate the anthropogenic factors that influence their presence in the sampling sites. In each of the five barangays, representing different habitat types, a 1 kilometer trail was established and visited twice a day until the species accumulation asymptote was reached. During each visit, photographic images of the avian species present were taken for documentation and identification purposes. There were 27 species of birds, belonging to 17 families, present in the sampling sites. Of these species, Passer montanus, Artamus leucorhynchus, and Hirundo tahitica were the most frequently sighted. On the other hand, Bulbopsittacus lunulatus was the least frequently observed bird. Majority of the birds inhabited the forest area, while others were found along riverbanks, in grasslands, and along the coasts. Except for Ceyx melanurus, which is listed as “vulnerableâ€, all other species were categorized as “least concern†under the IUCN Guidelines. Swidden agriculture slash and burn or kaingin and hunting for food and the pet trade affect the presence of birds in the sampling sites. Although there are still a number of species present, it is imperative that adequate protection and conservation measures are adopted and strictly implemented by the local government units. Joseph L.

This research examined the Bird Species Richness and Diversity in Armyworms Infested Maize Plots in Olabel Farms, Southwestern Nigeria. Survey Method: Point count method was used to collect data on bird species richness and diversity in the study area. In all five counting stations were used and counting bands of the 50 m radius were used for all the stations. One counting station per plot was used for this study. On arrival at the sites, birds were allowed time to settle before recording all the birds seen or heard for a predetermined time usually, 20 minutes. Bird calls were also recorded with a voice recorder and played back later for confirmation. Results: A total of 77 bird species belonging to 10 orders and 32 families were encountered in the study area; the order Passeriformes constituted the highest number of bird species in the study area. The family with the largest number of bird species is Accipitridae (n = 7). The composition of bird species obtained in this research revealed that it was not only insectivorous bird species that were encountered in the maize plots but also granivorous and frugivorous bird species that were present on the farm. They probably were feeding on the armyworms as protein supplements. From the results obtained, the relative abundance of the bird species in the study area indicated that Ploceus cucullatus has the highest of relative has abundance (0.0825) while the following bird species have the lowest relative abundance: Egretta intermedia (0.055), Streptopelia semitorquata (0.0325), and Vanellus lugubris (0.03). The Shannon_H diversity index was relatively higher (3.992) during wet season than dry season (3.661) when compared.

This document summarizes a study on the influence of seasonality and different types of Eucalyptus plantations on the abundance and diversity of litter insects in Rwanda. The study found that the order Hymenoptera was generally the most abundant across seasons. Abundance and diversity varied between plantation types and was generally higher in some Eucalyptus species compared to the native Entandrophragma excelsum. Diversity was highest in the dry season and declined in the rainy seasons, indicating heavy rain negatively impacts litter insects. The variability in insects is attributed to changing habitat conditions across seasons and plantation types.
This document summarizes a study on the population dynamics of the pod-sucking bug (Anopnocnemis curvipes) on pigeonpea crops under different planting densities and sowing times in Nigeria. The study found that the pest population was significantly higher on crops planted closer together (15cm x 35cm spacing) compared to those spaced farther apart (30cm x 60cm). It also found that the pest population was only present and highest on crops sown in October; it was absent on crops sown in April and July. Based on these findings, the study recommends that farmers in the region plant the improved pigeonpea cultivar at a wider spacing of 30cm x 60cm, sowing

The bean bug Chauliops fallax feeds exclusively on all leguminous crops in most regions of the world. The population density and spatial distribution of bean bug has been investigated on three different host plant i.e. soybean, cowpea and black gram (mash) under mid hill conditions of Himachal Pradesh during 2016. The fields of 600m2 and 300m2 area were selected as a sampling unit for sampling in soybean, cowpea and black gram. Him Palam Hara Soya -1, C-475 and Pant U19 genotypes of soybean, cowpea and mash were selected for the estimation of density and distribution of the bean bug. Different methods viz., Morisita’s index, Index of dispersion and Lewis index were used to calculate the density and distribution of the population of the pest. The mean population of bugs per plant was recorded on soybean (7.25) followed by cowpea (3.01) and black gram (1.21). Studies on knowing the distribution pattern of bean bug population under field conditions revealed that in soybean the distribution of bug was contagious (2.99) while in cowpea (2.44) and black gram (1.87) regular and contagious distribution pattern was found. The Z value of Morisita’s index in case of soybean was 9.98 followed by 5.87 and 3.50 in case of cowpea and black gram. Similar trend was found in case of Index of dispersion and Lewis index. Optimum sample sizes for estimates of the pest density in all the three host plants are presented.

Weeds are unwanted plant species growing in natural environment. Composition and abundance of weeds are influenced by number of environmental variables as well as farming practices in an ecosystem. Present study was formulated to measure the effect of environmental variables on weed species composition, abundance, distribution pattern and formation of various weeds communities in Union Council Shahbaz Ghari (total area 3956 ha, Agriculture land 1701 ha), District Mardan. Quantitative ecological techniques by adapting quadrat method were used to assess environmental variability and weed species distribution in the targeted region. Nine quadrats of 1×1 m2 size were placed randomly in 65 different fields of the UC. Phytosociological attributes such as density, frequency, relative density, relative frequency and Importance Values were measured for each field. Preliminary results showed that UC Shahbaz Ghari has 29 different weed species belong to 15 different families. Presence absence (1,0) data of 29 species and 65 fields were analyzed using Cluster and Two Way Cluster Analysesvia PC-ORD version 5 resulting four major weed communities. Dominant weed species of the area are Cyperus rotundus, Urochloa panicoides, Brachiaria ramosa, Dactyloctenium aegyptium, Commelina benghalensis and Canvolvulus arvensis while Cannabis sativa, Ipomea purpurea, Amaranthus blitoides, Xanthium strumarium, Lactuca dissecta and Cucurbita maxima are rare weed species. Indicator Species Analyses (ISA) of data identified indicators of each sort of micro environmental condition.

Conceptual notes on bioecology of raily(revised)mahobiag
Raily is an endemic ecorace of tasar silkworm found in Bastar, Chhattisgarh that feeds primarily on Sal trees. Studies have shown that Raily has a bivoltine lifecycle, producing two crops per year - one from July to September and another from October to January. Previous research has examined Raily's biology, ecology, and population dynamics under natural and experimental conditions to better understand and conserve this important resource for tribal livelihoods in the region. The proposed new study aims to further investigate Raily's lifecycle, host plant interactions, environmental impacts, and productivity over three years across natural and experimental sites.
ABSTRACT- Butterflies are the important pollinating agent for wild and crop plants. Despite of its global significance,
studies of butterfly diversity during monsoon and post-monsoon season in agroecosystem of Arjuni/Morgaon taluka of
Maharashtra have not been recently undertaken. Survey was carried out on butterflies of agricultural field during monsoon
and post-monsoon season, Arjuni/Morgaon, Maharashtra, India because it is now clear that in and around agricultural
fields particularly paddy field are unique ecosystems that provide some butterflies to complete their life span. Total 44
species of butterflies were recorded belonging to 32 genera and 5 families. Nymphalidae family is consisting of maximum
number of genera and species and only three species recorded from family Papilionidae. Maximum species richness
reported from July to November month. The present study will encourage the conservation of a wide range of indigenous
butterfly species in an area.

Seasonal changes on termite foraging behaviour under different habitats in ru...Alexander Decker
1. The study examined the effect of wet and dry seasons on termite foraging behavior and abundance in cropland, forest, and grassland habitats in Rufiji District, Tanzania over one year.
2. Termite abundance was significantly different between the three habitats, with the highest abundance found in croplands. However, termite species richness was not significantly different between habitats.
3. Termite abundance was higher during the wet season than the dry season across all habitat types due to increased food and moisture availability. Species richness was also generally higher in the wet season.
Vegetation mapping and multivariate approach to indicator species of a forest...Shujaul Mulk Khan
Abstract
Questions
Does the plant species composition of Thandiani sub Forests Division (TsFD) correlate with edaphic, topographic and climatic variables? Is it possible to identify different plant communities in relation to environmental gradients with special emphasis on indicator species? Can this approach to vegetation classification support conservation planning?
Location
Thandiani sub Forests Division, Western Himalayas.
Methods
Quantitative and qualitative characteristics of species along with environmental variables were measured using a randomly stratified design to identify the major plant communities and indicator species of the Thandiani sub Forests Division. Species composition was recorded in 10 × 2.5 × 2 and 0.5 × 0.5 m square plots for trees, shrubs and herbs, respectively. GPS, edaphic and topographic data were also recorded for each sample plot. A total of 1500 quadrats were established in 50 sampling stations along eight altitudinal transects encompassing eastern, western, northern and southern aspects (slopes). The altitudinal range of the study area was 1290 m to 2626 m above sea level using. The relationships between species composition and environmental variables were analyzed using Two Way Cluster Analysis (TWCA) and Indicator Species Analysis (ISA) via PCORD version 5.
Results
A total of 252 plant species belonging to 97 families were identified. TWCA and ISA recognized five plant communities. ISA additionally revealed that mountain slope aspect, soil pH and soil electrical conductivity were the strongest environmental factors (p ≤ 0.05) determining plant community composition and indicator species in each habitat. The results also show the strength of the environment-species relationship using Monte Carlo procedures.
Conclusions
An analysis of vegetation along an environmental gradient in the Thandiani sub Forests Division using the Braun-Blanquet approach confirmed by robust tools of multivariate statistics identified indicators of each sort of microclimatic zones/vegetation communities which could further be used in conservation planning and management not only in the area studied but in the adjacent regions exhibit similar sort of environmental conditions.
Out Crossing, Heterozygosis and Inbreeding with Environments Interaction in R...paperpublications3
Abstract:The progenies of five sorghum heterozygous populations’ cycles were tested under main and off-season on two different environments irrigated and rainfall conditions for their outcrossing, heterozygosity and inbreeding coefficient using SSR markers,the marker combinations were optimized according to their fragment size. Multi-locus outcrossing rate (tm) and average single-locus (ts) outcrossing rates were estimated using the MLTR software, and TFPGA computer program. The outcrossing rate effected directly by the temperature and relative humidity (RH) during the initial flowering period, which the low temperature with high RH under main season is revealed positive increased in outcrossing than off-season. Progenies outcrossing rate revealed same trend with main population outcrossing and the same trend was observed heterozygosity with decreased in inbreeding coefficient. Higher levels in outcrossing rate and heterozygosity was detected under rainfall environment in two based population progenies, but in three advanced population cycles the outcrossing rate was higher under irrigated than rainfed environment. Inbreeding coefficient revealed negative relation with outcrossing rate and heterozygosity in different population’s progenies.

This study analyzed the diet and habitat use of five frugivorous bird species in agroforest home gardens, secondary forests, and pastures in Brazil. The researchers found that overall habitat use frequency was higher in secondary forests than home gardens or pastures for four of the five bird species. However, the number of feeding bouts was higher in home gardens than forests for all species except one. Differences in monthly feeding activity were only statistically significant for two species. The total number of food taxa was larger in home gardens than forests. The results support agroforestry systems as an important habitat for frugivorous birds.

Diversity and abundance of terrestrial mammals in the northern periphery of ...Innspub Net
The Tanoé-Ehy Marsh Forest (TEMF), an unprotected forest that is about to be turn into a voluntary nature reserve is a forest block in south-eastern Côte d’Ivoire known as being of great importance for the conservation of biodiversity. But in the rainy season, that forest is largely over flooded and terrestrial mammals are likely to move to the periphery and make them vulnerable to anthropogenic threats. Our objectives are to determine the diversity, the relative abundance of terrestrial mammals and their spatial distribution in the northern periphery of the TEMF during the rainy season. We collected data by conducting recce surveys after interviews with local people. In total, we obtained 33 species among which ten primates’ species were identified. According to the recce survey, the African Civet (Civettictis civetta) and the Bushbuck (Tragelaphus scriptus) are the most common and abundant species in the study area with 12.7% and 12.0% of relative abundance respectively. In addition, six of the listed species are on the IUCN Red List, including Piliocolobus waldronae, a critically endangered species, Cercocebus lunulatus and Cercopithecus roloway endangered species, Colobus vellerosus, Phataginus tetradactyla and Phataginus tricuspis, three vulnerable species. Thus, the consideration of the periphery for the sustainable management of the TEMF is proving to be an imperative.
This study investigated genetic variability and divergence among five provenances of Faidherbia albida based on seed traits and germination. Seed length, width, thickness and weight were measured and a germination test was conducted. Significant differences were found among provenances for all seed traits except thickness, indicating genetic variability. Heritability for all traits was high, suggesting selection based on morphology can be effective. Principal component and cluster analyses separated provenances into three distinct clusters correlated with rainfall and altitude of origin. High genetic variation and heritability for seed traits makes them suitable for selection and breeding of F. albida provenances.
Mortality of Fayoumi and Sonali Chicks in Scavenging Rearing Systempaperpublications3
Abstract: Fayoumi and Sonali breeds are commonly reared under scavenging system in Bangladesh. Chick mortality has the very important impact on economy of farmers. The aim of the present study was to determine the mortality rate and the causes of mortality of Fayoumi and Sonali chicks. One observational cross-sectional study was done on the Fayoumi and Sonali chicks at Chittagong and Noakhali district from October 2005 to July 2006. A total of 48 farmers (24 from each Upazila) were selected randomly, who rear chicks under scavenging condition and as well as had broody hens. Twelve eggs of each breed were supplied to each farmer. The chicks were hatched out by the broody hens. Then the chicks were reared under scavenging system. The mortality detected for Fayoumi was 57.3%, which was less than that of the Sonali (68.8%) but did not vary significantly (χ2 = 1.21, df = 1, p > 0.05). The mortality of Fayoumi chicks at Noakhali site was little higher (59.1%) than that of Chittagong (55.4%), but it did not vary significantly (χ2 = 0.28, df = 1, p > 0.05). The mortality of Sonali chicks also did not differ significantly (χ2 = 0.16, df = 1, p > 0.05). The mortality was more by diseases than predators. The common predators were crow, wildcat, domestic cat, mongoose and rat in both study sites. The crow predated (Fayumi; 63.64% and Sonali; 70.83%) more baby chicks than others predators. The highest proportional mortality was caused by Mycoplasmosis + Colibacillosis (36.05 % and 36.94 %) in case of Fayoumi and Sonali followed by the second highest attributed to Mycoplasmosis (26.74%) and (22.52%) respectively. Fayoumi chicks were lower mortality than Sonali under scavenging rearing condition.

Investigation of Correlation Coefficient for Forage and Grain Yield with Rela...Premier Publishers
Oat (Avena sativa L.) is a staple worldwide in both human and animal nutrition. It is mainly grown for livestock, depending on its grain and forage yield in Turkey. This study was based on defining correlation coefficients of some oat genotypes (nine lines and three cultivars) in Konya, Turkey, among fodder and grain yields, and their components. The experimental design of this study was a randomized complete block design (RCBD) with three replications. The correlations were analyzed after harvesting at milk to dough period. The findings illustrated that there was a significant positive correlation between green fodder yield and leaf weights in ten stems, and grain yield and the number of panicles stems per square meter. The highest negative correlations was found between green fodder yield and the number of panicles stems per square meter, and grain yield and 50% flowering periods in addition to green fodder yield. This research suggests that the number of panicles stems per square meter and dry fodder yield would be selection criteria for grain yield. The number of leaves per stem, the number of nodes, and plant height would also be considered for green fodder yield by oat breeders in their program in Anatolia.

This document summarizes a study on the influence of seasonality and different types of Eucalyptus plantations on the abundance and diversity of litter insects in Rwanda. The study found that the order Hymenoptera was generally the most abundant across seasons. Abundance and diversity varied between plantation types and was generally higher in some Eucalyptus species compared to the native Entandrophragma excelsum. Diversity was highest in the dry season and declined in the rainy seasons, indicating heavy rain negatively impacts litter insects. The variability in insects is attributed to changing habitat conditions across seasons and plantation types.
This document summarizes a study on the population dynamics of the pod-sucking bug (Anopnocnemis curvipes) on pigeonpea crops under different planting densities and sowing times in Nigeria. The study found that the pest population was significantly higher on crops planted closer together (15cm x 35cm spacing) compared to those spaced farther apart (30cm x 60cm). It also found that the pest population was only present and highest on crops sown in October; it was absent on crops sown in April and July. Based on these findings, the study recommends that farmers in the region plant the improved pigeonpea cultivar at a wider spacing of 30cm x 60cm, sowing

The bean bug Chauliops fallax feeds exclusively on all leguminous crops in most regions of the world. The population density and spatial distribution of bean bug has been investigated on three different host plant i.e. soybean, cowpea and black gram (mash) under mid hill conditions of Himachal Pradesh during 2016. The fields of 600m2 and 300m2 area were selected as a sampling unit for sampling in soybean, cowpea and black gram. Him Palam Hara Soya -1, C-475 and Pant U19 genotypes of soybean, cowpea and mash were selected for the estimation of density and distribution of the bean bug. Different methods viz., Morisita’s index, Index of dispersion and Lewis index were used to calculate the density and distribution of the population of the pest. The mean population of bugs per plant was recorded on soybean (7.25) followed by cowpea (3.01) and black gram (1.21). Studies on knowing the distribution pattern of bean bug population under field conditions revealed that in soybean the distribution of bug was contagious (2.99) while in cowpea (2.44) and black gram (1.87) regular and contagious distribution pattern was found. The Z value of Morisita’s index in case of soybean was 9.98 followed by 5.87 and 3.50 in case of cowpea and black gram. Similar trend was found in case of Index of dispersion and Lewis index. Optimum sample sizes for estimates of the pest density in all the three host plants are presented.

Abstract
Questions
Does the plant species composition of Thandiani sub Forests Division (TsFD) correlate with edaphic, topographic and climatic variables? Is it possible to identify different plant communities in relation to environmental gradients with special emphasis on indicator species? Can this approach to vegetation classification support conservation planning?
Location
Thandiani sub Forests Division, Western Himalayas.
Methods
Quantitative and qualitative characteristics of species along with environmental variables were measured using a randomly stratified design to identify the major plant communities and indicator species of the Thandiani sub Forests Division. Species composition was recorded in 10 × 2.5 × 2 and 0.5 × 0.5 m square plots for trees, shrubs and herbs, respectively. GPS, edaphic and topographic data were also recorded for each sample plot. A total of 1500 quadrats were established in 50 sampling stations along eight altitudinal transects encompassing eastern, western, northern and southern aspects (slopes). The altitudinal range of the study area was 1290 m to 2626 m above sea level using. The relationships between species composition and environmental variables were analyzed using Two Way Cluster Analysis (TWCA) and Indicator Species Analysis (ISA) via PCORD version 5.
Results
A total of 252 plant species belonging to 97 families were identified. TWCA and ISA recognized five plant communities. ISA additionally revealed that mountain slope aspect, soil pH and soil electrical conductivity were the strongest environmental factors (p ≤ 0.05) determining plant community composition and indicator species in each habitat. The results also show the strength of the environment-species relationship using Monte Carlo procedures.
Conclusions
An analysis of vegetation along an environmental gradient in the Thandiani sub Forests Division using the Braun-Blanquet approach confirmed by robust tools of multivariate statistics identified indicators of each sort of microclimatic zones/vegetation communities which could further be used in conservation planning and management not only in the area studied but in the adjacent regions exhibit similar sort of environmental conditions.

This study investigated genetic variability and divergence among five provenances of Faidherbia albida based on seed traits and germination. Seed length, width, thickness and weight were measured and a germination test was conducted. Significant differences were found among provenances for all seed traits except thickness, indicating genetic variability. Heritability for all traits was high, suggesting selection based on morphology can be effective. Principal component and cluster analyses separated provenances into three distinct clusters correlated with rainfall and altitude of origin. High genetic variation and heritability for seed traits makes them suitable for selection and breeding of F. albida provenances.
Mortality of Fayoumi and Sonali Chicks in Scavenging Rearing Systempaperpublications3
Abstract: Fayoumi and Sonali breeds are commonly reared under scavenging system in Bangladesh. Chick mortality has the very important impact on economy of farmers.

One observational cross-sectional study was done on the Fayoumi and Sonali chicks at Chittagong and Noakhali district from October 2005 to July 2006. A total of 48 farmers (24 from each Upazila) were selected randomly, who rear chicks under scavenging condition and as well as had broody hens. Twelve eggs of each breed were supplied to each farmer. The chicks were hatched out by the broody hens. Then the chicks were reared under scavenging system. The mortality detected for Fayoumi was 57.3%, which was less than that of the Sonali (68.8%) but did not vary significantly (χ2 = 1.21, df = 1, p > 0.05). The mortality of Fayoumi chicks at Noakhali site was little higher (59.1%) than that of Chittagong (55.4%), but it did not vary significantly (χ2 = 0.28, df = 1, p > 0.05). The mortality of Sonali chicks also did not differ significantly (χ2 = 0.16, df = 1, p > 0.05). The mortality was more by diseases than predators. The common predators were crow, wildcat, domestic cat, mongoose and rat in both study sites. The crow predated (Fayumi; 63.64% and Sonali; 70.83%) more baby chicks than others predators. The highest proportional mortality was caused by Mycoplasmosis + Colibacillosis (36.05 % and 36.94 %) in case of Fayoumi and Sonali followed by the second highest attributed to Mycoplasmosis (26.74%) and (22.52%) respectively. Fayoumi chicks were lower mortality than Sonali under scavenging rearing condition.

The experimental design of this study was a randomized complete block design (RCBD) with three replications. The correlations were analyzed after harvesting at milk to dough period. The findings illustrated that there was a significant positive correlation between green fodder yield and leaf weights in ten stems, and grain yield and the number of panicles stems per square meter. The highest negative correlations was found between green fodder yield and the number of panicles stems per square meter, and grain yield and 50% flowering periods in addition to green fodder yield. This research suggests that the number of panicles stems per square meter and dry fodder yield would be selection criteria for grain yield. The number of leaves per stem, the number of nodes, and plant height would also be considered for green fodder yield by oat breeders in their program in Anatolia.

Various kinds of crops are grown among which wheat is cultivated on large scale. In order to explore weed species diversity in the region, a phytosociological survey was conducted in the summer 2014. Such study was required as there has been no such record of weeds diversity of the region. Different fields were selected at various localities of the district. The total number of fields selected was 120 and in each field 10, 1x1m 2 quadrats were laid. A questionnaire was also circulated to investigate about the farming practices and most dangerous species of weeds having greater effect on production and post harvest losses of wheat. Plants were collected from various localities, voucher numbers were given to specimens and other relevant data pertaining to locality i.e., habitat, habit, family, scientific and local names of each species. Mounted copy of each voucher specimen was deposited to the Herbarium of Hazara University Mansehra. This study not only provided first inventory of weed plants but it also helped point out most dangerous species related to wheat yield losses. Results of this study revealed a total of 132 weeds plant species belonging to 110 genera and 42 families. Most of the species investigated were Angiosperms. Family Asteraceae was the richest family related to species diversity with 18 species and 17 genera. It is followed by Poaceae having 16 species and 16 genera. Next in succession are family Brasicaceae with 10 genera and 16 species and family Boraginaceae with 5 genera and 7 species. Other families like Caryophyllaceae, Papilionaceae, Fabaceae, Polygonaceae, Scrophulariaceae and Umbilliferae have 6,6,4,5,4 and 3 species and 6,3,4,3,3 and 3 genera respectively. Species like Silybum marianum (Asteraceae), Emex spinosa (Polygonaceae) and Circium arvense (Asteraceae) are considered to be the most threatening species during the time of harvesting the crop. Further study along this line is the basic part of the on-going project which will provide a base line for the development of agricultural crops in the region.
Distribution of macrozoobenthos in river narmada near water intake pointAlexander Decker
This document summarizes a study on the distribution of macrozoobenthos in the River Narmada near a water intake point in India. Five sampling stations were established along the river reach. A total of 35 taxa from 3 phyla were identified. The highest diversity was found at the upstream station I with 31 species identified. Diversity decreased at stations closer to the water intake point, with only 9 species identified at station III in front of the intake. This loss in macrozoobenthos distribution near the water intake point indicates that the ecological conditions are degrading due to the impact of the water intake infrastructure on the river habitat. In conclusion, the study shows that the water intake point is altering the riverine habitat and
AM Fungal Status in Ketaka: Pandanus fascicularis From Coastal Region of Konk...IOSR Journals
Present paper deals with assessment of Arbuscular mycorrhizal fungi (AM) associated with different populations of Pandanus fascicularis found in coastal region of Konkan Maharashtra. All samples of P. fascicularis roots were colonized by AM fungi. The mean percentage of root length colonization ranged from 39% to 74%. Amongst the thirteen AM fungal morphospecies Kuklospora colombiana was the most widely distributed species. Species richness of AM fungi ranged from 3 to 6. Based on spore density and relative abundance, three species were dominant viz., Acaulospora bireticulata, A. scrobiculata, and K. colombiana. Details of AM fungal status in P. fascicularis are discussed in present paper.

The pattern of field infestation by the flea beetles, Podagrica spp., was assessed in okra-kenaf intercrop system with a view to determining a cropping pattern that would assist in controlling the pest problem. Okra and kenaf were intercropped in row combinations of 1:1, 1:2, 2:1 and 2:2 while sole-cropped okra and kenaf served for comparison. Field sampling for flea beetles commenced three weeks after planting and it lasted till the 12th week, a period that extended to the postharvest stage of okra. There was a significant difference (P Ë‚ 0.01) between the population of the two Podagrica spp. (with P. uniforma being more abundant than P. sjostedti) and among the six planting patterns. The pest population also differed (P Ë‚ 0.05) between the two crops and among (P Ë‚ 0.001) the vegetative, reproductive and postharvest stages of okra. Sole kenaf had a significantly higher level of infestation by the flea beetles followed by sole okra and two rows of okra intercropped with one row of kenaf in descending order. All the other three intercrop patterns had a significantly lower infestation level. Kenaf attracted more flea beetles than okra at the vegetative stage while stumps of okra left in the field after harvesting was over sustained a significantly higher population of flea beetles. Obtained results showed that intercropping could be used, especially by poor rural farmers, as a pest control strategy against Podagrica spp. Due to the considerable population of flea beetles sustained by okra stumps, farmers should be encouraged to get rid of leftovers after harvesting as a way of further controlling Podagrica spp. The combination of intercropping and farm sanitation would assist in reducing reliance on synthetic chemical insecticides.

Evaluation of rice genotypes for resistance to the stalk-eyed fly (Diopsis lo...Innspub Net
Globally, rice production is limited by abiotic and biotic factors. Of the insect pests attacking rice, the stalk-eyed fly is the most abundant. Major rice growing districts in Uganda are affected, and varieties grown by farmers are susceptible. The objective of this study was to identify sources of resistance to stalk-eyed flies among improved rice genotypes in Uganda. Fifty genotypes from the Africa Rice Centre, IRRI, South Korea and the National Crops Resources Research Institute (NaCRRI) in Uganda were screened under cage and field conditions at NaCRRI. Trials were laid out in an alpha lattice design, with 3 replications, for both experiments. Natural infestation (D. longicornis or D. apicalis) was used in the field while cage trials utilized artificial infestation with D. longicornis. Data on deadhearts were collected from seedling to tillering stages, at 7, 14, 21 and 28 days. Analyses of variance were performed using restricted maximum likelihood. Infestation levels for 31 (62%) rice genotypes were the same under both field and cage conditions, 4 (8%) genotypes showed higher susceptibility in the cage than in the field and 15 (30%) were more resistant in the cage than in the field. Genotypes NERICA 4, TXD306, NM7-22-11-B-P-1-1 and K85 were identified as the most resistant varieties. F3 genotypes (GSR IR1- 5-S14-S2-Y1 x K85, Gigante x NERICA4, NERICA4 x Gigante, NERICA1x NERICA4, NERICA4 x NERICA6, and NERICA4 x SUPA) were also found resistant. These genotypes were recommended for release and further advancement, respectively.

Weed species composition and distribution pattern in the maize crop under the...Shujaul Mulk Khan
Weeds are unwanted plant species growing in ordinary environment. In nature there are a total of 8000 weed species out of which 250 are important for agriculture world. The present study was carried out on weed species composition and distribution pattern with special reference to edaphic factor and farming practices in maize crop of District Mardan during the months of August and September, 2014. Quadrates methods were used to assess weed species distribution in relation to edaphic factor and farming practices. Phytosociological attributes such as frequency, relative frequency, density, relative density and Importance Values were measured by placing 9 quadrates (1 × 1 m2) randomly in each field. Initial results showed that the study area has 29 diverse weed species belonging to 27 genera and 15 families distributed in 585 quadrats. Presence and absence data sheet of 29 weed species and 65 fields were analyzed through PC-ORD version 5. Cluster and Two Way Cluster Analyses initiated four different weed communities with significant indicator species and with respect to underlying environmental variables using data attribute plots. Canonical Correspondence Analyses (CCA) of CANOCO software version 4.5 was used to assess the environmental gradients of weed species. It is concluded that among all the edaphic factors the strongest variables were higher concentration of potassium, organic matter and sandy nature of soil. CCA plots of both weed species and sampled fields based on questionnaire data concluded the farming practices such as application of fertilizers, irrigation and chemical spray were the main factors in determination of weed communities.
Out Crossing, Heterozygosis and Inbreeding with Environments Interaction in R...paperpublications3
Abstract:The progenies of five sorghum heterozygous populations’ cycles were tested under main and off-season on two different environments irrigated and rainfall conditions for their outcrossing, heterozygosity and inbreeding coefficient using SSR markers,the marker combinations were optimized according to their fragment size. Multi-locus outcrossing rate (tm) and average single-locus (ts) outcrossing rates were estimated using the MLTR software, and TFPGA computer program. The outcrossing rate effected directly by the temperature and relative humidity (RH) during the initial flowering period, which the low temperature with high RH under main season is revealed positive increased in outcrossing than off-season. Progenies outcrossing rate revealed same trend with main population outcrossing and the same trend was observed heterozygosity with decreased in inbreeding coefficient. Higher levels in outcrossing rate and heterozygosity was detected under rainfall environment in two based population progenies, but in three advanced population cycles the outcrossing rate was higher under irrigated than rainfed environment. Inbreeding coefficient revealed negative relation with outcrossing rate and heterozygosity in different population’s progenies.
Notes on the diet of seven terretrial frogs in three agroecosystemsRodrigo Souza Santos

The study titled “Status of Bushbuck (Tragelaphus scriptus) and Buffalo (Syncerus caffer) in the North and South Eastern parts of the Kimbi-Fungom National Park (K-FNP) of the North West Region of Cameroon” was carried out in the rainy season from 1st May to 31st July 2015. The general objective was to contribute to the conservation of bushbuck and Buffalo in the K-FNP through the establishment of status of mammals which will serve as a guide for management decisions. The methodology employed was the “recce-walk”. Twenty seven (27) lines transects of 2 km long each were walked making a total effort of 53km. One hundred and fifty six (156) questionnaires were administered to the local population, twenty one (21) semi-structured interviews to households and seven (7) focus group discussions with local chiefs and notables were used to get local people’s perceptions about wildlife conservation in the NP. Results revealed a total of 13 species of mammals within the NP belonging to 6 families. The Bovidae family had the highest number of species represented by the buffalo (Syncerus caffer), bushbuck (Tragelaphus scriptus), the blue duiker (Cephalophus monticola) and the red duiker (Cephalophus dorsalis). The buffalo and the bushbuck recorded encounter rates of 0.85 and 0.34sign/km respectively. The Buffalo had a higher density in the North East of the South East compartment of the park while the bushbuck had a higher density in the south west of the north east compartment. There was a strong relationship (R2=0.792) between the encounter rate of mammals and anthropogenic activities. Ninety two (92.31%) of respondents recognized the importance of the NP because they depended on it for collection of NTFP’s (34.60%), hunting of Bushmeat (12.80%), fuel wood gathering (7.70%), religious activities (6.40%), agricultural land (5.10%), harvesting of medicinal plants(5.10%), source of clean water (5.10%), traditional rituals (3.80%) and traditional medicine harvesting (2.6%). Ninety seven percent (97.2%) supported wildlife conservation because of its touristic, aesthetic and for sustainability. Thirty four percent (34.60%) of the respondents were aware of community implication in managing the NP. K-FNP is poor in species abundance, species richness and flagship species. Associated benefits from ecotourism are far-fetched coupled with encroachment by grazers. We therefore recommend that the government, councils, NGOs and the local communities should step up conservation efforts.

Assessment of Genetic Diversity in Sesame (Sesamum indicum L.) Genotypes at B...Premier Publishers
Field experiment was conducted to assess the extent of genetic diversity in sesame (Sesamum indicum L.) genotypes to identify superior genotypes for further improvement program. A total of forty-nine sesame genotypes were evaluated at Bako and Uke during 2018 cropping season. Data were recorded and analyzed by SAS software. The combined analysis showed significant differences among the genotypes for all traits. Cluster analysis grouped 49 sesame genotypes into four clusters. The highest inter-cluster distance occurred between clusters three and four while the lowest was between clusters one and two. Principal components analysis showed that about 76.1% of the total variations among sesame genotypes were contributed by the first four PCs with eigen values greater than unity. Estimation of phenotypic diversity based on qualitative traits showed seed color and flower color were the highest divergent traits followed by stem color and leaf color. Generally, the result of the study showed existence of significant genetic variability among tested genotypes. Therefore, simple selection of promising genotypes and crossing of highly divergent group to produce best heterotic offspring could be recommended from the present study.

Bioaccumulation of Lead (Pb) content in three species bivalves in Jakarta Ba...Innspub Net
Environmental pollution by heavy metals has become a serious problem in Jakarta Bay. Mobilization of heavy metals as a result of anthropogenic activities has caused the release of heavy metals into the environment, one of which is Pb. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. In addition heavy metal pollutans in the waters are very stable and tend to be persistent. Recently, bioaccumators is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective using bivalves. These study objectives to analyzed the Pb content of three species of Jakarta Bay bivalves. The results showed that Pb content in the Eastern and Western Season bivalve tissue was significantly lowest in P. viridis (0,166 ± 0,016μg/g dan 0,161 ± 0,155μg/g) compared the Pb concentration in A. antiquata (0,264 ± 0,015μg/g dan 0,247±0,044μg/g), and M. meretrix (0,270 ± 0,016μg/g dan 0,240 ± 0,053μg/g). In this study also showed that the concentration of heavy metal Pb in the bivalve shell of P. viridis was significantly lower than that of two species (A. antiquata and M. meretrix). Pb content in the Eastern Season bivalves did not significantly different from that in the Westerrn Season. This is caused by a weather anomaly where the rainy season occurs almos throughout year of 2020. The Pb content in the bivalves shell was significantly higher than in the body tissues. It is because Pb can replace calcium ions in the formation of animal bones or bivalve shells.
Interaction on the diet and substrate on the growth of Archachatina marginata...Innspub Net
Nine hundred juveniles of Archachatina marginata aged about two weeks, with an average live weight of 2.25 g with an average shell length of 20.12mm were monitored in culture for six (6) months on five types of substrates [S1 (soil collected in a cassava plantation: Manihot sp.), S2 (S1 with 10% oyster shell meal), S3 (S1 with 10% sawdust), S4 (S1 with 5% oyster shell meal and 5% sawdust) and S5 (uncultivated forest soil). Four diets including two industrial (D1 and D 2 of 12% and 16% calcium respectively) and two based on fodder (D3 and D4 based on leaves and fruit of the papaya (Carica papaya) on the one hand and a mixture of papaya leaves and taro (Xanthosoma maffafa) on the other hand, were used. In order to determine the best combinations inducing the best growth performance, 20 combinations were formed at the rate of 45 spat for each combination; three replicas of 15 spat each. This study showed that the combination of diet and livestock substrate influences the growth of Archachatina marginata. Although the best feed is D1 (74.68 g and 7.94cm) and the best substrate is S2 (77.12 g and 7.79cm), the best combinations are D2S3 (69.37 g and 7.47cm), D1S4 (74.68 g and 7.94cm and D4S2 (77.12 g and 7.79cm). The combined effect of the high level of dietary calcium and that of the culture substrate does not promote good growth of snails. This work will help improve the production of African giant snails and provide important data for anyone wishing to engage in the breeding of these animals.

No previous research has assessed the nongenetic factors, especially the nutrition status of MS patients in Arab countries. Hence, this study aims to assess the nutritional status of MS patients among Arab adults. This study is a nationally representative cross-sectional study using a structured, online self-administered, validated quantitative food frequency questionnaire (FFQ) from 13 Arab countries. All data analyses were performed using STATA 16.0 and R for statistical computing version 4.0.4. A total of 813 participants were surveyed, most of the MS participants were female (68.4%), married (58.5%), non-smoker (72.6%) and 53.3% were diagnosed with MS for up to five years. MS participants did not consume the DRI of both the macro and the micronutrients including the energy requirements, except the dietary intake of the sodium which was insignificantly different from the DRI. Results also showed that most participants rarely consumed the main food items including bread, cereals, and most types of meat. While, more than 50% of the participants consumed fruit, vegetables, all types of chicken, fish, fresh soup, rice, and egg up to 3 times per month. On the other hand, milk and milkshake were consumed rarely; while, tea and herbal teas were the most common beverages. Nutrient deficiencies are very common among MS Arab patients. The finding of this study can establish a base for the development of a nutritional program for MS patients in accordance with the recommended DRI.

A germination test was carried out to identify plants that can germinate and survive in polluted soil (with and without ash) collected 2.5km east and 2.5km west, 20km west and 55km west (control) of the BCL Cu/Ni mine smelter in Selebi-Phikwe, Botswana. The experiment was carried out using Phaseolus vulgaris, Moringa oleifera and Moringa stenopetala. Soil acidity and heavy metal stress reduced germination percentage, coefficient rate of germination, root and shoot growth and dry weight, root: shoot, vigour index and tolerance index of all species. Percentage reduction followed the order 2.5km west < 20km west < 2.5km east < 55km west. Phaseolus vulgaris, Moringa oleifera and Moringa stenopetala germinated in all soils. Their ability to germinate in polluted soil indicates tolerance to heavy metal and soil acidity stress and so they have potential for use in phytoremediation of polluted soils around the mine. Phaseolus vulgaris had the highest overall germination performance but there was no significant difference between the Moringas. Application of coal fly ash increased all the germination parameters and so coal fly ash has potential for use in amending polluted soil around the mine for phytoremediation purposes.
Identification and marketing of Marantaceae in the Ndjolé area, in central Ga...Innspub Net
The forests of the Congo Basin cover an area of 200 million hectares, of which just over 10% is in Gabon. In this country, crop products and non-timber forest products (NTFPs) are abundant because of its favourable climate. There is significant biodiversity and great potential for non-timber forest products. This study is interested in the identification and the supply chain of the Marantaceae, one of these NTFPs of plant origin in central Gabon, whose exploitation is national. Through a survey of the main actors in the sector and field visits in the locality of Bifoun, it emerges the existence of three large groups of exploited marantaceae, whose harvest and transport are mainly done by women, in various containers. The storage of this NTFPs does not exceed four days, with the risk of losing its commercial value due to drying out. The uses of this resource are multiple: processing cassava, cooking food, making handicrafts, etc. The income it provides to producers is mainly use towards small family expenses but helps to monetize the rural world. The difficulties inherent in the distance from harvesting points, the low price of the product and the impossibility of long-term storage of the marantaceae leaves constitute a brake on the development of this activity. It would therefore be wise to envisage the domestication of the species listed for a sustainable use of this plant genetic resource.
Ethnobotany of Oyster nut (Telfairia pedata) in Northern Tanzania | JBES 2022Innspub Net
Telfairia pedata (Sims) Hook is an important native climber plant commonly grown in East Africa. It bears nuts which are eaten either raw or cooked and is consumed mostly by expectant mothers, and as cooking oil. The survey was conducted between September 2019 to February 2020 in Sambaa, Meru, and Pare communities of Lushoto, Bumbuli, Arumeru and Same Districts, Northern Tanzania to assess the ethnobotany of T. pedata from a sample of 346 respondents using semi-structured questionnaires. Results indicate that, 21% of respondents used T. pedata for cooking with other staple foods while 18% claimed that the nuts are used by pregnant and lactating mothers for medicinal and breast milk stimulation and nine (9) percent indicated that the nuts are used for cultural and ritual purposes. Despite its importance, the cultivation of T. pedata in the study area is declining and the gap why such decline is experienced needs to be answered in further studies. Secondly, respondents within the 36-50 age groups reported the greatest diversity of uses of T. pedata 51% compared with those aged below 36 years old 21% signifying that the traditional knowledge known by younger aged groups may be declining. Thus, this gap of traditional knowledge between the groups should be addressed in order to improve utilization and conservation of this seriously declining yet important nut in the study area and other places of Tanzania.

Dearth of well-articulated information on genetic parameter estimates and diversity of upland rice limits the genetic improvement of rice. This study assessed the genetic parameter estimates and genetic diversity among 40 rice accessions using 26 agro-morphological traits. The trial was conducted in 2020 at the Njala University experimental site using 5 × 8 triple lattice design. The agro-morphological traits were analyzed using various multivariate and genetic parameter estimate techniques. Classification based on qualitative and quantitative traits grouped the germplasm into ten and five distinct clusters, respectively. Genotypes Buttercup-ABC, Buttercup-RARC, Jewulay, NERICA L4, Ndomawai, Sewulie and Painipainie produced earliest days to heading (81.8–97.2 days) and maturity (111.2 – 120.7 days). Genotypes Jasmine (3.036 t.ha-1), Rok 34 (3.238 t.ha-1) and Parmoi (2.663 t.ha-1) exhibited the highest grain yields. Principal component analysis (PCA) of qualitative traits exhibited four principal components (PCs) with eigenvalues > 1.0 and cumulative variation of 68.04%, whilst the PCA of quantitative traits had five PCs accounting for 81.73% of the total genetic variation. The findings indicate the presence of enough variability that could be exploited for the genetic improvement of rice varieties and the studied traits can be used for selection. Leaf blade length and width, culm diameter at basal internode, culm length, days to 50% heading, flag leaf girth, panicle number per plant, grain yield, and 100 grain weight had high heritability and genetic advance indicating the presence of additive gene action. Findings are relevant for conservation, management, short term recommendation for release and genetic improvement of rice.

Observations were made from September 2019 to February 2021 at the selected three sites during COVID 19 pandemic. Point count method was used for bird surveys and Sound pressure (Noise) measurements were made across the three selected sites. The Avian diversity was measured by total species richness, Fisher’s alpha diversity index and Shannon-Wiener diversity index. The Urban centre recorded the highest sound pressure and lowest Avian species richness but as we moved away from the urban centre the noise levels reduced and the avain species richness increased towards the rural areas. This is mainly due to many avian species avoiding urban areas because of increasing noise levels. We also found that the urban bird community is dominated by a few species whereas the rural bird community was much more diverse.
Construction health and safety model towards adoption | IJB 2022Innspub Net
This study aimed to assess the safety and health of contractors in Zamboanga Del Norte, Philip-pines, in terms of workforce, workplace, and work implements. It also aimed to evaluate compliance with occupational health and safety standards regarding occupational safety and health training, a health and safety plan, civil works activities, and heavy equipment operations. It combined quantitative research with a self-created questionnaire that explains and forecasts concepts that can be applied to other people and locations and objectively measures the variable(s) of interest, selected, constructed, and standardized with validity and reliability in mind. The findings revealed that respondents only partially adhered to construction safety and health in personnel, workplace, and work equipment. Occupational health and safety criteria were partially met in occupational safety and health training, health and safety plans, civil works activities, and heavy equipment operations. The Level of Compliance for construction safety and health was also partially met. As a result, it is advised that construction companies will adopt the revised construction safety model.

Impact of climate change on wheat yield using remote sensing technique | JBES...Innspub Net
This document summarizes a study that analyzed the impact of climate change on wheat yield in three districts of Pakistan from 1999-2014 using remote sensing techniques. The study found wheat production fluctuated over this time period in all three districts. Some years had higher rainfall and temperatures led to lower yields, while other years with more optimal rainfall and temperatures produced higher yields. Overall, the data showed increasing rainfall trends but unstable wheat production in the districts. The study concluded that satellite remote sensing could help predict crop yields and manage food crises given changing climate conditions.
Extreme weather events and their impact on urban crop production: A case of K...Innspub Net
This document summarizes a study on the impact of extreme weather events on urban crop production in Kinondoni District, Tanzania. The study found that farmers perceived increased occurrences of floods, extreme temperatures, and drought. These events negatively affected crop production by damaging crops, causing low yields, outbreaks of pests and diseases, and drying of water sources. Farmers employed adaptation strategies like crop diversification, pesticide use, changing cropping patterns, irrigation, and replanting crops. The study recommends adopting new farming systems like vertical farming to improve output with limited land and water resources under climate change.
Effectiveness of community forest association and water resource users’ assoc...Innspub Net
Catchment degradation has continued to occur globally albeit the presence of Community Forest Associations (CFA) and Water Resource Users Associations (WRUA). Similarly, Kilungu catchment area in Kenya is under the management of the Kenze (CFA) and upper Kaiti (WRUA). This paper examined Kenze CFA and Upper Kaiti WRUA activities by exploring their effectiveness in discharging their statutory functions. This was achieved by carrying out, an exploratory descriptive survey. Data was collected through questionnaires, focus group discussions, 10 key informants’ interviews and direct observations. Descriptive analysis was used. Information was presented in fig.s, tables and percentages. Results showed that upper Kaiti WRUA as more effective in catchment management at moderately (31%) and highly at (37%) as compared to CFA moderately (29%) and highly (5%). In terms of discharging of their statutory functions, Upper Kaiti WRUA was better at a rating of 27% (good) and 23% (very good) as compared to Kenze CFA which was rated at 3% (good) and 6% (very good). This study results implied that Upper Kaiti WRUA was more effective in all aspects of ensuring catchment management as opposed to CFA. In conclusion, a strategy of seizing the opportunities presented by the CFA of being empowered to perform all its activities as required by law with emphasis on the timely preparation and implementation of management plans and WRUA’s continuous improvement should be prioritized. The study recommends new initiatives that improve on the CFA and WRUA activities in order to effectively discharge on their statutory functions.

Liming leads to high bean and maize yield on a strongly acid tea soil | IJAAR...Innspub Net
This study investigated the effects of different liming rates on maize and bean yields in strongly acidic tea-growing soils in Kenya. The soils had pH values below 5, indicating aluminum toxicity and deficiencies in important nutrients. Liming raised the soil pH and increased both maize and bean yields significantly compared to the unlimed control. The maximum yields for both crops were achieved at a liming rate of 6 t/ha, which raised the soil pH to around 5.5. Higher liming rates did not further increase yields and started to decrease them, possibly due to nutrient imbalances. The results show that liming is an effective and inexpensive way to reclaim strongly acidic tea soils and improve food crop production.

The ethanol, ethyl acetate, and hexane extracts of the freshwater clam (Corbicula fluminea) were studied for the total phenolics and total flavonoids. Total phenolics and total flavonoids of the extracts were evaluated using Folin-Ciocalteau and Aluminum chloride colorimetric methods respectively. The findings showed that the total phenolics of the ethanol extract (1.67±0.28mg GAE/g of dried sample) were substantially higher than the total phenolics obtained from the ethyl acetate (0.70±0.00mg GAE/g) and hexane extracts (0.56±0.23mg GAE/g). While the total flavonoids in the ethyl acetate extract displayed a slightly higher total flavonoid (43.84±0.92mg QE/g of dried sample) relative to ethanol (30.41±1.34mg QE/g of dried sample) and hexane extracts (20.28±0.00mg QE/g of dried sample). Using ethanol, the highest yield for extraction was obtained. Ethanol is the best solvent among the three – ethanol, ethyl acetate, and hexane in terms of extraction yield and total phenolics. In addition, it can be inferred that the presence of significant amounts of phenolics and flavonoids suggests that freshwater clam is a promising source of antioxidants that provides nourishing proteins and oxidative stress remedies

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Abstract
The present study was designed to record the distribution of ground dwelling spider genera among mustard crop
at Okara district. Sampling was made from Brassica compestris crop through pitfall traps. Equal number of traps
were placed in three rows e.g. along the boundary, middle of the field and centre of the field. Each trap was filled
with mixture solution of alcohol and glycerin (70:30%) along with few drops of kerosene oil. After 5 days interval
sample traps was collected and spider specimens were washed with distilled water and permanently stored in
labeled glass vials, and brought into the Pest Control Laboratory, Department of Zoology, Wildlife and Fisheries,
University of Agriculture, Faisalabad. Thereafter, each spider specimen was identified according to the taxonomic
material and internet source. Identified data was analyzed statistically to quantify their spatial distribution.
Maximum spatial distribution of spider population was documented in middle transect than boundary and centre
of the mustard crop. It was also observed that temperature, humidity and prey availability were the major factors
that effecting the spider population. Population variations were recorded during the months of February, March
and April in 2015, due to rise of temperature, decrease of humidity and availability of prey. Conclusively, spiders
have some correlation with suitable local conditions or habitat. More over, spiders are cost effective, functionally
significant and play important role in regulating decomposer population.

Introduction
Fodder crops including mustard are particularly refer
to food for animals or live-stock. They comprise of
straw, hay, pelleted feed, silage, oils, legumes and
sprouted grains. Currently in Pakistan, various fodder
crops are cultivated over 15 million hectares with 52
million ton annual fodder production (Anonymous,
2013). However, suitable rainfall and temperature
range can enhance the present outcomes (Hussain et
al., 2010). Because, in many parts of Pakistan, there
is abrupt shortage of fodder for live-stock, and also
the available fodder is of poor quality. The farmers
are facing a lot of problems to get maximum forage
yield to meet the feed requirements. Improved fodder
varieties along with control of damage by invading
insect pest can overcome the situation. Mustard crop
provides valuable supplemental food to live-stock
community e.g. nitrogen, energy, minerals and
vitamins. Consequently, it increase the availability of
nutrients for maintenance and ideal production
status. (Douglas et al., 2000).
To enhance the yield, control of insect pests is a major
issue and use of spiders to control these insect pests is
of profound importance. Spiders have globally more
than 40,000 identified species (Platnick, 2012). They
have remarkable abundance and are highly
diversified terrestrial predator especially in agro-
ecosystems (Wise, 1993).
They can play a pivotal role in keeping insect and pest
populations in check and balance and they are also
serve as food for birds, snakes, fish and other animals.
They eat insects and bugs which destroy different
crops and consequently safeguard the agro-
ecosystems. By habitat management. We can
conserve the diversity of natural enemies (including
spiders) of arthropod pest (Douglas et al., 2000).
Perennial crops and degree of heterogeneity in
their surrounding landscape have a positive effect
on their abundance and species richness among
cultivated land (Clough et al., 2005).
Spider’s abundance and diversity vary in different
agro-ecosystems and they have temporo-spatial
distribution in all agricultural lands to effectively
destruct the insect pest population (Seyfulina and
Tshernyshev, 2001; Seyfulina, 2003). Their breeding
success is directly related to amount of precipitation
which act as potential factors to affect the abundance
and species richness (Thomas et al., 2014). They are
most important arthropods for economic point of
view playing role as biological control agent and their
adaptation towards different habitats (Kazim et al.,
2014).
Keeping in view the importance of spider densities
and role of mustard in live-stock sector, the present
study was designed to record the population
dynamics and spatial distribution of ground dwelling
spider families and genea among mustard crop at
Okara district.
Materials and methods
Study area
The present study was designed to record spatial
distribution of ground dwelling spiders among
mustard crop at Okara district. Because information
about their distribution in any agro-ecosystem was
pre-requisite to formulate any strategy to use them
for bio-control purposes. Presently, these
informations were recorded from Okara district.
Mustard crop was cultivated in one acre rectangular
field. The sampling field was surrounded by wheat
fields from two sides, where as on third side, it was
surrounded by a Trifolium and Mustard field.
Okara district
Okara district is situated in Punjab province at 30,
8081 (304829.160”N) latitude and 73, 4458
(732644.880”E) longitude. This district is bounded
on the East by Kasur district, Sahiwal and Pakpattan
districts on the West, Sheikhupura and Faisalabad
districts on the North and Bahawalnagar district on
the South. The Indian border also lies on the South-
Eastern side of the district. Okara district has a total
area of 4,377 square kilometres and comprises of
three tehsils i.e. Okara, Depalpur and Renala Khurd.

Climate
The climate of the Okara district is hot in summer and
cold in winter. May and June are hottest months and
January is the coldest one.Temperature ranges
between 36-440C in summer and 2-280C in winter.
Soil of the district is loamy and sandy loamy with
annual rainfall up to 200 mm.
Sampling design and techniques
The sampling was carried out from October, 2014
through April, 2015 to collect the ground dwelling
spider fauna in mustard crop.Total thirty traps were
set in the field for five successive days. The two
successive traps were at equal distance from each
other and the distance from outer boundary of the
field was 5m. Pitfall traps were 12cm long glass jars
with 6cm (diameter) wide mouths. Each trap
contained 150 ml of 70% ethyl alcohol and a small
amount of kerosene oil which served as preservative
and killing agent.Ten pitfall traps were laid along
each transect line i.e. boundary, middle and centre at
an equal interval from each other.
Collection of data
For mustard crop, ideal field measuring 7200 sq. ft.
were selected to observe the spatial distribution of
ground dwelling spiders through pitfall trap method.
However, trapping was made by three layers inside
the field radius wise to observe the infestation along
the entire field. Data was collected fortnightly and
collected specimens were brought into the Pest
Control Laboratory, Departmentof Zoology, Wildlife
and Fisheries, University of Agriculture, Faisalabad.
All the specimens were identified according to the
reference material.
Preservation
All traps were taken to Pest Control Laboratory,
Department of Zoology, Wildlife and Fisheries,
University of Agriculture, Faisalabad. Where the
specimens were washed with xylene and preserved
in 95% ethanol containing few drops of glycerin.
Specimens were preserved separately in small glass
vials indicating with trap number and the date of
capture.
Identification
The collected samples were identified with the aid of
naked eye, magnifying glass and under the
microscope. All the specimens were identified up to
species level according to the taxonomic and
reference material (Tikader and Malhotra (1982),
Tikader and Biswas (1981), Barrion and Litsinger
(1995), Zhu et al. (2003), Platnick (2012), other
relevant literature and internet source.
Statistical analysis
Thereafter, all the identified specimens were arranged
in table form according to their morphological
characters e.g. family, genus. To determine the
various aspects of diversity, Shannon Diversity Index
was used (Magurran, 1988). Analysis of Variance was
made to compare the population means between
three transects, i.e. Boundary, middle and centre of
mustard crop. The richness, diversity and evenness
indices were computed by using the Programme
SPDIVERS.BAS.
Results
The present study was conducted to highlight the
population dynamics of ground dwelling spider
genera among mustard crop at Okara district. A total
number of 421 specimen pertaining to 21 genera and
7 families among mustard crop were identified from
Okara district (Table 1).
Population variations among families in mustard
crop
Data presented in Table 2, is pertaining to family’s
wise comparison of spider’s population recorded from
two fodder crops during the study. In Mustard crop,
the population of wolf spiders – family Lycosidae was
recorded with highest population (N = 147), followed
by Flat bellied ground spiders – family Gnaphosidae
(N = 90), Sheat weaver spiders – family Linyphiidae
(N = 75), Jumping spiders –, Orb-weaver spiders –
family Aranidae (N = 34), Crab spiders-- family
Thomisidea (N = 33) and Sac spiders—family

117 | Rana et al.
Clubionidae (N = 21) and family Salticidae (N = 21)
respectively. The maximum population of family wolf
spiders – family Lycosidae was recorded due to that
they were strictly ground dwelling spiders. Second
and third highest population recorded were of Flat
bellied ground spiders – family
Gnaphosidae and Sheat weaver spiders – family
Linyphiidae respectively due to the reason that they
were also ground living and live in high vegetation
density, so the existing environment was supportive
for them. However, minimum population of
identified spiders in case of Jumping spiders – family
Salticidae followed by Orb-weaver spiders – family
Araneidae, Crab spiders -- family Thomisidea and Sac
spiders — family Clubionidae was recorded from
mustard field.

5 Lycosidae 147 4
6 Salticidae 21 2
7 Thomisidea 33 3
Total 7 421 21
Their low population was recorded due to that they
live in leaf litter and shaddy areas. The study area was
surrounded by wheat crops from north and east side
and mustard crop from west side. Whole cultivated
area was comprised of crop land and there were no
shaddy trees near the study area. Direct temperature
variation hazards and use of different pesticides on
crop lands become a reason for their decline in
population. Another reason for their least collection
was that, they were foliage spiders and the pitfall
method was applied for the collection of spiders.

Population variations among genera in mustard
crop
Data presented in Table 3, is regarding the
comparison of spiders’ population among genera
recorded in berseem and mustard fields during the
study. Maximum population of identified genera in
mustard crop was recorded in case of genus Evapa
(N=60) followed by Lycosa (N=41) and Gnaphosa
(N=38) respectively. Because they were ground
dwelling spiders but live in shelter places while in
mustard field, fodder was cut down again and again
that’s why their minimum population was recorded.

Comparison of diversity indices among mustard
crop
Data presented in Table 5, is pertaining the month
wise comparison of diversity indices among genera
from mustard crop. Overall genera wise maximum
diversity (H”) recorded in Mustard crop during the
month of November was 2.8053, evenness 0.9527 and
dominance 0.0473 respectively. During the month of
December maximum diversity 2.2719, evenness
0.9867 and dominance 0.0133 was recorded. During
the month of January maximum diversity 1.7918,
evenness 1.0000 and dominance 0.0000 was
recorded. During the month of February maximum
diversity 2.8116, evenness 0.9386 and dominance
0.0614 was recorded. During the month of March
maximum diversity 2.8618, evenness 0.9400 and
dominance 0.060 was recorded. During the month of
April maximum diversity 2.8191, evenness 0.9259
and dominance 0.0741 was recorded. Maximum
diversity 2.8618 was recorded during the month of
March. While, evenness 1.0000 and dominance
0.0741 were recoded during the month of January
and April respectively.
Relative abundance
Pie graph (Fig.1) represent the relative abundance of

identified spider families in mustard crop at Okara
district. Maximum abundance of spiders was
recorded in case of family Lycosidae 35% followed by
Gnaphosidae 21% and Lyniphiidae 18%. Minimum
abundance of spiders was recorded in family
Araneidae 7% followed by Clubionidae 6% and
Salticidae 5% respectively. Maximum relative
abundance was recorded during start of November.
However, ratio of relative abundance was equal in
start of December and January. It increased gradually
up to April and then decreased.

Analysis of variance
Data represented in Table 6, pertaining to Analysis of
variance for transect-wise abundance of different
genera of spiders for mustard crop.The mean number
of spider genera in mustard crop at district Okara was
statistically similar. The mean number of spider’s
population month wise and transect wise were
statistically highly significant (P<0.01). The mean
number of spider’s population during the month of
December (4.00±0.82) and January (2.33±0.71) were
statistically non significant (P>0.05), when compared
with mean number in November (11.50±3.03),
February (26.33±6.73), March (42.33±9.22) and
April (60.83±11.79) was statistically significan
(P<0.05). Crop x Transect-wise mean number of
spider genera in boundary (27.50±8.82) and middle
(34.00±12.87) were statistically non significant
(P>0.05) when compared with mean number in
centre (8.67±3.71) was statistically significant
(P<0.05) among mustard crop. Overall mean number
of spider genera in mustard crop (23.39±5.66) was
statistically non significant (P>0.05).
Discussion
Seasonal variations in spider population
Evidences regarding sesaonal variations of spider
population was underlined by considering the
findings of previous researchers because field type,
management pattern, agronomic operations and use
of pesticides, soil culture and floral structures
significantly affect spider’s population (Liljesthrom et
al., 2002; Ahmad et al., 2005; Pradeep et al., 2015).
It was also estimated that start of breeding season,
enhancment in growth and acceleration in maturity
were proportional to temperature and humidity. As
temperature reached above 25°C, start in breeding
occur and with decrease in temperature up to the
same situation and increase in humidity, it comes to
the end. Findings of present study are in agreement
with Rajeswaran et al. (2005); Dippenaar-Schoeman
(2006); Mushtaq et al. (2003 & 2005); Kazim et al.
(2014), Pradeep et al. (2015).
It is obvious from the indices calculations that
spider’s abundance decrease with the decrease in
9. J. Bio. Env. Sci. 2016
122 | Rana et al.
temperature and increase in humidity. These findings
support the earlier reports of Mushtaq et al. (2003 &
2005); Iqbal et al. (2009) and Pradeep et al. (2015).
Resultantly, ecological imbalance of prey verses
predators develops which upset the all ecological
pyramids and natural cycling. Sustainable prey and
predator status is limiting for integrity of any natural
system for long term functions. These findings are in
same cotext as reported by Rajeswaran et al. (2005);
Dippenaar-Schoeman (2006); Mushtaq et al. (2003 &
2005); Kazim et al. (2014), Pradeep et al. (2015).
Conclusion
Conclusively, despite to cosmopolitan nature, spiders
have some correlation with suitable local conditions
or habitat. However, it was also observed that spider’s
population in the same study region were also
effected by increase or decrease in temperature and
humidity. So, there is necessity of future research for
the proper use of spider fauna as biological control
agent in IPM programmes.
