Biodiversity
Biodiversity refers to the variety of life on Earth, including genetic, species, and ecosystem diversity. It can be measured by wealth, the number of species in an ecosystem, and relative abundance, the number of individuals of each species. Threats to biodiversity include human destruction through deforestation and hunting as well as climate change. These threats can be reduced through indirect means like decreasing pollution or direct actions such as protecting natural areas.
Measuring biodiversity
This document discusses methods for quantifying biodiversity, including species richness, species evenness, and Simpson's Index. Species richness is a count of the total number of species in an area, while species evenness measures how similar the abundances of each species are. Simpson's Index incorporates both richness and evenness to calculate a single value representing biodiversity, with lower values indicating higher diversity as it takes into account the number of species and how evenly abundant each species is. The document provides examples to illustrate how to calculate and apply Simpson's Index using data on species abundances in different communities.
Biodiversity
This document discusses biodiversity and its conservation. It begins with definitions of biodiversity and explains that it represents the variety of life on Earth. It then describes the three types of biodiversity: diversity of species, ecosystems, and genes. Key topics covered include the distribution of biodiversity globally and within India, benefits provided by biodiversity, threats to biodiversity like habitat loss, and approaches to conservation like protected areas and environmental education. International agreements to protect biodiversity are also summarized, along with recent biodiversity-related events.
The measurement of biodiversity
This document discusses various methods for measuring biodiversity, including species richness, evenness, disparity, and genetic variability. It notes that biodiversity cannot be reduced to a single number due to the complexities of various taxonomic concepts and differences in ecosystems. While higher productivity generally correlates with greater biodiversity, preserving biodiversity poses challenges for policymakers given difficulties in comparing biodiversity across environments.
Loss of biodiversity
loss of biodiversity is the most important in biodiversity and conservation.it is useful to reduce the activities which are responsible for extinction and endangering of living organisms.
Biodiversity
This document defines biodiversity and describes its levels and value. It discusses genetic, species, and ecosystem diversity. Biodiversity provides consumptive use value through food, medicine, and fuel. It has productive use value when commercially used. Biodiversity also has social, aesthetic, option, and ecosystem service values. Major threats include habitat loss and poaching.

Population and Community
This document defines key population and community ecology concepts. It discusses [1] what a population is, factors that affect population size, density, and distribution. [2] Population growth is influenced by natality, mortality, immigration, emigration, and environmental resistance. Carrying capacity is the maximum population size an environment can sustain. [3] Communities are formed by populations interacting in an area. Relationships like predation, competition, and symbiosis shape community structure. Producers, consumers, and decomposers fill different roles. Habitats provide resources while niches define an organism's function. Energy and nutrients flow through food chains and webs.
Biodiversity : An overview
Biological diversity' means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.”

Biodiversity
This document discusses biodiversity and its conservation. It defines biodiversity as the variety of life on Earth, including diversity at the genetic, species, and ecosystem levels. It notes that scientists have identified over 1.4 million species so far, but many more remain unknown. Biodiversity provides many benefits to humans, such as food, medicine, and ecosystem services. However, biodiversity is threatened by habitat loss, pollution, overexploitation, and other human impacts. The document discusses strategies for conserving biodiversity, including protecting habitats through systems of protected areas (in situ conservation) and off-site conservation methods like seed banks and zoos (ex situ conservation).
ecosystem diversity
An ecosystem is defined as a community of living organisms interacting with each other and their non-living environment. The document outlines six main ecosystem types: forest, ocean, grassland, tundra, wetland, and desert. It provides examples of the key characteristics of each ecosystem, such as forests containing many trees, oceans supporting marine life, grasslands being home to grasses and insects, and wetlands being areas saturated with water.
Species diversity
1. Species diversity refers to the number and variety of species in a given region. It takes into account both the number of species and how evenly abundant they are.
2. There are three main types of species: endemic, exotic, and cosmopolitan. Endemic species are restricted to a particular area while exotic species have been transported by humans.
3. Factors that affect species diversity include speciation, extinction, migration, habitat destruction, and the introduction of invasive species. Speciation occurs through geographic isolation or reductions in gene flow. Extinction can be caused by overharvesting, pollution, and habitat loss.
Species Extinction- Reasons and Effects?
In biology and ecology, extinction is the termination of an organism or of a group of organisms normally a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost at this point.

Type of biodiversity
Biodiversity refers to the variety of life on Earth at all levels, from genes to ecosystems. There are three main types of biodiversity: genetic diversity within species, species diversity between ecosystems, and ecosystem diversity across landscapes. Maintaining biodiversity is important as each species and ecosystem provides vital services like food, medicine, stable climate, water purification and more, with global economic value estimated at $16.54 trillion annually. Loss of any species or ecosystem impacts these services and reduces nature's ability to adapt over time.

Natural Resource Depletion - Reasons & Effects
Natural resources are being depleted at unsustainable rates due to factors like population growth, pollution, and overconsumption. This depletion affects human health through increased poverty and atmospheric changes. Renewable resources like water and non-renewable resources like fossil fuels are being exhausted. Conservation efforts like alternative energy sources, recycling, and sustainable agriculture can help reduce the effects of natural resource depletion.
Population ecology
Population ecology is the study of populations in relation to their environment. It examines factors like population size, density, dispersion patterns, demographics, survivorship curves, and population growth. Population size is influenced by birth rate, death rate, immigration, and emigration. Population density is measured as the number of individuals per unit area. A population's dispersion can be random, uniform, or clumped. Demographic factors include age structure, sex ratio, and life tables. Survivorship curves illustrate survival rates at different ages. Population growth can be exponential or logistic depending on environmental limits.
PPT OF BIODIVERSITY
This document provides an overview of biodiversity, including its definition, types, distribution, benefits, threats, and conservation. It discusses how biodiversity represents the variety of life on Earth and is vital to sustaining human life. The three types of biodiversity are genetic diversity, species diversity, and ecosystem diversity. While biodiversity is threatened by habitat loss and other human impacts, conservation efforts aim to protect biodiversity through protected areas, restoration, and environmental policies.
Importance of biodiversity to humanKinds
Biodiversity is essential for human well-being and survival. It provides vital goods and services like food, medicine, clean air and water. Each species, no matter how small, plays an important role in ecosystem productivity and sustainability. At least 40% of the global economy and 80% of needs of poor people are derived from biological resources. Biodiversity also has immense aesthetic, cultural and spiritual value for humans. While we have benefited from biodiversity in many known ways, most of its benefits are still unknown as important species and ecosystem functions have yet to be discovered. Loss of biodiversity therefore poses a major threat to humanity's future welfare and progress.

Biodiversity refers to the variety of plant and animal life on Earth or within a particular ecosystem. It exists at three main levels: genetic diversity within species, diversity of species within an area, and diversity of ecosystems within a region. Biodiversity is important for ecological, economic, and scientific reasons. Loss of biodiversity is occurring due to factors like increasing human population and land use, natural disasters, pollution, and overhunting. Conservation efforts aim to preserve endangered and vulnerable species and protect important habitats to maintain biodiversity and ecosystem balance.

Biological Diversity, Raymond F. Dasmann in 1968.
Term biodiversity was coined in 1985, W.G. Rosen in 1985.
Charles Darwin: All species were linked in a single great phylogeny, or tree of life, and that all could be traced back to a presumed single original species at some distant time in the geological past.
basic presentation on agricultural biodiversity
This document discusses the importance of agricultural biodiversity. It defines agricultural biodiversity as the variety of crops and livestock used in agriculture as well as the genetic diversity within each type. Agricultural biodiversity is the foundation of agriculture as it provides genetic resources and supports ecosystem services. However, modern agriculture has also damaged biodiversity through land conversion and intensification. To address this, farmers need support adopting practices that conserve biodiversity while meeting food demands, such as using diverse crop varieties that are resilient to climate change and pests. Maintaining agricultural biodiversity is crucial for ensuring food security, health, traditional knowledge and adapting to future challenges.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
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.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

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.

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 pptx
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.
