Maria Elisa B. Gerona1 and Florence C. Evacitas2 ABSTRACT With limited inconclusive data provided by gut content analysis, stable isotope analysis has recently emerged to validate trophic position and dietary intake. In this study, a dual isotope approach was used to reveal parrotfish feeding. Comparisons of δ13C and δ15N values of muscle and liver among …

Samuel L. Malayao1 and Teodoro C. Mendoza2 ABSTRACT Two agroforestry systems, a fruit tree-based with lanzones (Lansium domesticum) as dominant fruit tree and a forest tree-based with falcata (Paraserianthes falcataria) as dominant wood tree, were studied to compare their total carbon stocks in the above ground biomass (upperstorey and understorey), floor litters and soil and …

Jedess Miladel C. Nuñez ABSTRACT The abaca industry is in crisis because of the bunchy-top disease which has destroyed thousands of hectares of abaca (Musa textilis Nee). While government and research efforts are focused on the eradication of the disease, this study brings attention to the changes in people’s livelihoods and conditions due to the …

Olufemi Olutoyin Richard Pitan and Caroline Oyindamola Filani ABSTRACT In Nigeria, published information on the range and relative importance of different pests on cucumber is scanty. Studies were therefore carried out in a survey to determine the insects associated with cucumber, and on-field to quantify insectinduced damage at different crop growth stages. Surveys were carried …

Lorina A. Galvez1, Remberto A. Patindol2 and Linda B. Mabesa3 ABSTRACT The main problem of the dehydrated jackfruit developed by the Visayas State University (VSU) is that it develops browning after one to two months even if the product is packed in a good packaging material. This study was conducted to determine the effects of …

Daniel Leslie S. Tan1, Julie D. Tan1, Mark Anthony R. Atanacio1 and Ruel B. Delantar2 ABSTRACT Energy from edible and inedible root crop roots and tubers using galvanic cell and processing wastewaters through microbial fuel cell (MFC) technology was harnessed. Electrolyte in the roots and tubers was tapped for galvanic cell and the microorganisms from …

Elizabeth S. Quevedo1, Antonio C. Laurena2 and Florinia E. Merca3 ABSTRACT The physicochemical properties and nutritional profile of the different parts and stages of maturity of “batuan” [Garcinia binucao (Blco.) Choisy] fruits in the Visayas State University (VSU) were determined using standard analytical methods to validate their use as a safe food ingredient. Sensory evaluation …
