Disasters and Ecosystem: Philippine SettingASU-CHARRM
NSTP Lecture-Presentation (May 22, 2015)
An overview of the link between ecosystem and disaster on the preparedness, prevention & mitigation measures that environment can offer us before, during and after disaster happens.
Aquatic macrophytes functions in several ways in water bodies, they are critical to Niger Delta inland waters because they enhance the physical structure of the habitat which serves as living space for small aquatic animals and play a vital role in fisheries production. Macrophytes play an important role in the aquatic environment but unfortunately very little attention is being directed towards the conservation of these aquatic resources and they can get out of control and create problems when they are not properly managed. This paper examines common aquatic macrophytes in Niger Delta in Nigeria with emphasis on benefits, problems and also proffers best practices for adequately managing the macrrophytes in Niger Delta inland waters.

Evaluation of the Ichthyotoxicity of Dioscorea Dumetorum on the African Catfi...AJSERJournal
Dioscorea Dumetorumtubers are used in stupefying fish for easy harvesting in Akwa Ibom State, Nigeria
specifically in Annang part of the state. D. dumetorum belongs to the family of Dioscoreaceae and is commonly known
as bitter yam. This study was conducted to determine the bioactive components and evaluate the acutetoxicity of the
aqueous extract of the D. dumetorum on C. aariepinus fingerlings and anuran tadpoles. The 96hLC50 values of D.
dumetorum tuber aqueous extracts were determined in the laboratory under static bioassay conditions against C.
aariepinus fingerlings and anuran tadpoles. Range finding bioassays were conducted to get the range of concentrations
for the definitive bioassays. The range of concentrations of test media for C. aariepinus fingerlngs was 0.6-5mgl-1 while
that of anuran tadpoles was 1.6-3.8mgl-1
. The median lethal concentrations (LC50) were determined using probit
analysis. The 96hLC50 value of the test plant against exposed fingerlings was 2.153mgl-1 with lower and upper
confidence limits of 1.869 and 2.485mgl-1
respectively while that of tadpoles was 2.538mgl-1 with lower and upper
confidence limits of 2.295 and 2.771 mgl1
respectively. Unpaired t-test showed that there was no significant difference
(p>0.05) between the toxicity of the test plant to C. aariepinus fingerlings and that of anuran tadpoles. The mean water
quality parameters were within the optimal range requirement for the test species. The study indicated that D.
dumetorumexerted piscicidal property on C. aariepinus fingerlings and anuran tadpoles. The indiscriminate use of this
plant to catch fish by local fishermen should be discouraged.

A study on growth performance of Spirulina platensis in different concentrati...AbdullaAlAsif1
An experiment was conducted on culture and growth performance of Spirulina platensis in various concentrations of rotten apple medium (RAM) and Kosaric Medium (KM). The observation was conducted for three months from March to May at the Live Food Culture Laboratory, Department of Aquaculture, Faculty of Fisheries, Bangladesh Agricultural University. Culture of S. platensis was performed in 1.0L glass flasks in three different media such as 2.5, 5.0 and 10% and KM with three replications under fluorescent light in light : dark (12 hr : 12 hr) condition of a period of 14 days. Growth performances of S. platensis varied from one medium to another. The initial cell weight of S. platensis was 0.0023 mg/L and a maximum cell weight of 12.44 mg/L was found in KM and 10.468 mg/L in RAM on 10 th day of culture. It was also observed that, the initial chlorophyll a content of S. platensis was 0.0015 mg/L which was attained at a highest content of 10.54 mg/L in KM and 12.35 mg/L in RAM on 10 th day of culture. A decreasing trend of cell weight was observed from 10 th day of culture. The growth of S. platensis was significantly (p<0.05) better in 5.0% Digested Rotten Apple Medium (DRAM) than other concentrations 2.5% DRAM and 10% DRAM. From the results obtained in the present study, it was summarized that the growth of S. platensis was better in the concentrations of 5.0% DRAM than other concentrations of RAM. Thus, the concentration of 5.0% DRAM is most suitable for S. platensis culture compare with standard KM. These media are easily available and most inexpensive in contrast of Bangladesh. So digested rotten apple can be used for commercially and economically viable mass culture of S. platensis.
Cactus Pear, Cladodes (opuntia ficus –indica); as Forage for Livestock in
Arid and Semi-Arids of Ethiopia feeding under a changing climate-A
Review
Poor feed quality and lack of water are the major constraints for livestock production under arid and semiarid conditions. Cactus pear (Opuntia ficus-indica) is an extremely drought tolerant, highly productive, multipurpose and succulent plant. It has incomparably high water and land use efficiency. In cactus pear producing regions of Ethiopia its fruits play life-saving role during rainy seasons while livestock depend mainly on its cladodes during dry seasons and drought years. The problem of feed shortage is more aggravated in arid and semi-arid areas where erratic nature of the rainfall hampers crop production. During the dry season, there is under nutrition and malnutrition of livestock. In this regard cactus pear is known to have great potentialThis review provides the effect of supplementation of spineless cactus (Opuntia ficus indica) and selected browse species mixture on feed, in order to give the basis of their use in water intake, digestibility and body weight. More studies on Opuntia ficus-indica could help better understand its nutritional health, combination with other feeds, fortification mechanism of action to provide clear scientific evidence to explain its traditional uses, and to identify its therapeutic potential in other diseases.
ABSTRACT: Philippines is known for its vast biodiversity as a mega diverse country. On a per-unit-area
basis, it boasts the most diversified life forms. Its biodiversity, which includes a diverse range of flora and
wildlife, provides supplies for human survival, fosters economic development, and provides environmental
services. However, the country's biodiversity may be threatened by inappropriate usage and management. The
country has been designated as a biodiversity hotspot and a high conservation priority worldwide. Policies to
protect and conserve biodiversity in the country have been implemented, including legislation on access and
benefit sharing.
Valorization of the duckweed (Spirodela polyrhyza) in the feeding of mono sex...Innspub Net
In order to evaluate the effect of Spirodela polyrhiza using in diets of Oreochromis niloticus fingerlings, an experiment was conducted on the farm “Awara” in the village of Agongo in Sèmè – Kpodji during 70 days. The initial average weight of fry is about 1g. The stocking density was 13 fry / m². Three experimental diets made with local by-products were tested: T0 (0% S. polyrhiza Meal), T1 (5% S. polyrhiza Meal) and T2 (mixed feed composed of 70% T0 and 30% fresh S. polyrhiza). At the end of the experiment, the survival rate was 100% for all treatments. The best zootechnical parameters were obtained with T1 with a final average weight of 11.67 ± 2.52 g and a consumption index of 1.17 ± 0.30. The highest gross profit margin was also obtained with T1. The lowest economic profitability was obtained.
booklet on wildlife.Plants from the Sterculiaceae family are herbs, shrubs, trees, or climbers. Some species are glabrous while others have stellate hairs or peltate scales. The leaves spiral or whorled, and can be either simple or palmately compound. Their margins may be entire, lobed, or toothed with 3-5 veins originating from the base of the leaf. Stipules are present but inconspicuous. The inflorescences are axillary paniculate cymes or cauliflorous fascicles. Flowers are functionally unisexual, exhibiting radial symmetry, and can be solitary or paired. In some cases, the petals may be minute, scale-like, or even absent. Male flowers with prominent stalks that carry both stamens and carpels called androgynophore. Anthers dithecal or with two chambers. Fruit are apocarpous and takes the form of a loculicidal capsule, or rarely a berry or samara.

Species diversity and functional groups of ants (Hymenoptera: Formicidae) in ...Innspub Net
Ants play a vital role in various ecological processes in the ecosystem. They are involved in nutrient cycling, soil aeration, seed dispersal, and indicator of habitat condition. The study was conducted to determine the species diversity and functional group composition of ants near the residential area and agro-ecosystem of Mt. Agad-agad, Brgy. Puga-an, Iligan City, Philippines. Ants were collected using baits and hand collecting to sample ants. A total of 4,047 individuals belonging to four subfamilies, 17 genera, and 23 species were documented in the two sampling sites. Species diversity was recorded highest in agro-ecosystem with H’=2.74 and species richness of 3.96. Also, five invasive species, including Paratrechina longicornis was recorded in both sampling sites. The most abundant functional group was Generalized Myrmicinae (36%) near the residential area, while Subordinate Camponotini (29%) in Agro-ecosystem. The result suggests that existing land-use influences species and functional group composition of ants, and the presence of invasive species indicates the magnitude of anthropogenic disturbances in the area.
The annual global production of fishmeal and fish oil is currently around five million tonnes of meal and one million tonnes of oil (Figure 1), except in years when the fishing in the South Pacific is disrupted by the warm waters of an El Niňo, most recently in 2010. Around 22 million tonnes of raw material is used, of which approximately 75 percent comes from whole fish and 25 percent from by-products of processing fish for human consumption (IFFO estimates).

“SECTION 4. Grant of Mineral Agreements Pending New Legislation. No new mineral agreements shall be entered into until a legislation rationalizing existing revenue sharing
schemes and mechanisms shall have taken effect. The DENR may continue to grant and issue Exploration Permits under existing laws, rules and guidelines.” - Executive Order No. 79, July 6, 2012.
The report is based on a desk study and a three-week
field trip to the Philippines, where data was gathered
through qualitative interviews. Interview partners included
affected communities, company representatives, local and
national civil society organizations, as well as government
authorities. By evaluating this data we shed light on the
main human rights issues linked to the Tampakan Project.
The choice of our interview partners reflects our human
rights approach. While our interviewees have both positive
and negative attitudes towards the Tampakan Project, they
do not constitute a representative sample of the population
in the area. Instead, our goal is to make sure that we include those people who have serious concerns with regard to their human rights situation and to analyze their hopes and fears and complement this information with desk research and the views of other stakeholders and experts.
Prior to the start of stock exchange trading on 5 January 2012, Intex issued a stock exchange announcement stating that it had signed a MoU with MCC8 for the development of its nickel project in Mindoro. This agreement could grant MCC8 a “project management contract” (“PMC”) which would mean that MCC8 would take on most of the responsibility for the project finance and development of the field. As consideration for this, MCC8 and its strategic partners would have an option to purchase up to 90% of Mindoro Nickel, in a staged process, for a total of USD 296 million. Intex would retain 10% and would have an option to buy back a further 10% for up to USD 60 million following completion of the project1.

FOR: Violation of R.A. 9275 and Its
Implementing Rules and Regulations
25 February 2013
With an estimated $1.4 trillion in reserves, Philippine mining potential ranks
fifth in the world, covering an estimated 9 million hectares, but less than
2% has mining permits. After long stagnation, the sector has been coming
back after a 2005 SC decision affirming RA 7942, considered a world-class
legal framework for sustainable development. Minerals development is a
government priority and has great potential for jobs and revenue. Government
has identified over 60 priority PPP projects. Mining can support poor
rural areas through high quality jobs, local tax payments, and community
development. The national government receives substantial royalty and tax
payments. Government revenue from mining increased 800% from 2002 to
PhP10.4 billion in 2007. However, full development of the sector continues
to face significant challenges. Lengthy, tedious approvals for Exploration
Permits (EPs) continue to impede investment. Several LGUs have closed their
provinces to mining. Industry is concerned that the Writ of Kalikasan might
disturb lawful activities. An investor cannot tell easily if land is ancestral land.
Skilled Mines and Geosciences Bureau (MGB) personnel often leave public
service. EO 79 has imposed a moratorium on new mining permits, pending the
passage of a new law on the revenue-sharing scheme between industry

58. Summary & Conclusions
• ThePhilippines is indeed a country of very high
biodiversity in terms of species
y p
• “hot spot” because of high rates of habitat
But a
destruction & extinction
• 20% of amphibians and reptiles locally extinct
20%
in 50-
i 50-60 years due t forest destruction and
to d
fragmentation
59. Summary & Conclusions
• causes of decrease in abundance are heavy
Other
exploitation and hybridization with domestic
species, e.g. wild pig on N
i ild i Negros, crocodiles
dil
• Manyspecies of higher animals are threatened
due to alien species invasion, e.g. Cyprinids of
Lake Lanao
• Many plant species are threatened with extinction
for various reasons

“At the end of the day, in a more
democratic world, it will be the
world
ethics and desires of the

people, not their leaders, who
give power to government and
the NGOs or take it away. They
will decide… and choose

whether particular species will
live or die.”
