Distinct morphological features of traditional chickens (Gallus gallus domesticus L.) in Western Visayas, Philippines
(Cambridge University Press, 2012-12)
The local or traditional types of chicken found in the Philippines are not well described and no comprehensive information is available and as yet not described as breeds. Among the regions in the Philippines, Western ...
A study on the invertebrate and vertebrate biodiversity of the Jalaur River system of Iloilo, Panay, Philippines
(Silliman University, 2010-01)
This study, conducted from July to November 2009, aimed to explore the diversity of large aquatic and terrestrial organisms found in microhabitats along the Jalaur River System on Panay Island, Philippines. We adopted a purposive sampling approach using several collection techniques appropriate to particular taxa or group of taxa. These include the netting method for birds and bats, cruising and transect methods for herpetofauna, gill-net fishing for aquatic vertebrates and quadrat method for macro- invertebrates. Data were analyzed for species richness (S) and relative abundance, and for fish, catch per unit effort (CPUE) and income per unit effort (IPUE). Three areas, representing the upper, middle, and lower portions of the river, served as the sampling sites. The results of the study show that there are at least 106 species of terrestrial vertebrates and about 71 species of aquatic vertebrates and macro-invertebrates in the area. These include 22 endemic species of terrestrial vertebrates, a new Philippine record of the goby Trypauchenopsis intermedia and an undescribed goby of the genus Rhinogobius. Of the 51 species of fish observed in the area, 36 species (70.59%) are known to inhabit marine and brackish water habitats, while 14 species (27.45%) inhabit freshwater. Only one catadromous species of fish, Anguilla marmorata, was observed in the area. The study also identified nine exotic species of fish and two species of freshwater mollusks are harvested in the area. The terrestrial vertebrate species diversity appears to be depauperate....
Job change and self-control of waste pickers: Evidence from a field experiment in the Philippines
(Business Perspectives, 2018-06-15)
Environmental policies may have a negative side effect on employment, often in a specific industry in the short run. Workers in regulated industries can be affected by losses in job-specific human capital. The informal ...

Environmental effects on the resistance of rice seedlings to complete submergence
(Crop Science Society of America (CSSA), 1972-03-01)
The survival of rice seedlings (Oryza sativa L.) after complete Submergence in water decreased with increased duration of submergence; with increased depth, temperature, and turbidity of water; and with increased rates of N fertilization. Survival increased with high light intensity and plant carbohydrate content. Factors that influence the survival of submerged plants also determine the amounts of N and carbohydrate in the plant....
