    Distribution of scleractinian corals in Taklong Island, Guimaras for the period December 2001 to January 2002
    Bodoso, Daniel P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2002-02)
    The study of the distribution of scleractinian or hard corals genera was done in Taklong Island, Nueva Valencia, Guimaras from December 2001 to January 2002, employing the line-intercept method. Twenty-one (21) genera were identified within three survey sites with an average coral cover of 33.4% for all the study sites. Forties was the dominant genera and was followed by other massive colonial corals such as Goniastrea, Favites, Pavona, and Platygyra and by the branching genus Acropora.

    Meiofaunal assemblages in the mangrove habitat in Taklong Island, Nueva Valencia, Guimaras
    Bocoran, Mary Grace G. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-03)
    Meiofauna are metazoans that can pass through a sieve with a mesh of 0.5mm but retained in a mesh of 0.063mm sieve. These organism are interesting to benthic scientist due to its capacity to determine the extent of pollution in the area and its role in the food web of an ecosystem. This study aims (1) to come up with a list of meiofaunal species present in the mangrove substratum, (2) to determine its density and abundance, and (3) to describe the meiofaunal environment in terms of temperature, salinity , pH, and oxygen content. The study was conducted in the mangrove habitat in Taklong Island Guimaras in February 1997. Thirty core samples were collected with a modified PVC core ( diameter=2.0 cm, length=15cm) from 3 areas: seaward, middle, and landward portions of the mangrove. There were eight broad groupings of meiofauna considered: nematodes, copepods, malacostracans, polychaetes, gastrotrichs, kinorhynchs, sipunculids, and others (including forams). The nematodes, of which there were 2 species observed, were the most abundant and comprised 42.14%. The copepods had 3 species observed and comprised 31.05%, 2 species of polychaetes comprised 5.04%,2species of gastrotrychs comprised 3.86% and malacostracans were 6.66%, kinorhynchs were 3.26%, and sipunculids were 0.89%. Unidentified organism which included foraminiferans, were 8.01 %. Range of meiofaunal density (number of individuals per cm'3 ) in three transects were 0.0042-0.1549 in the seaward area,0.0085-0.0785 in the middle area and 0.0021-0.0679 in the landward area. The nematodes had the highest density, and the sipunculids had the lowest density from the seaward to the landward area.

    A comparison of the gut contents of two Cardinal Fish, Fowleria vaiulae (Jordan & Seale 1906) and Fowleria variegata (Valenciennes 1832) in seagrass beds of Palompon, Leyte
    Biantan, Lindsay S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)
    Seagrass ecosystems support much of the Philippines’ coastal marine resources with the presence of a rich diversity of species, including the economically important ones. Understanding the diet composition of fishes through gut content analysis is essential for selecting species for aquaculture. Specimens of Fowleria vaiulae and Fowleria variegata were obtained through a trawl survey in the seagrass beds of Palompon, Leyte from November 2011 to February 2012. A total of 291 guts were analysed in this study. Results showed diet composition of both species is mostly made up of benthic invertebrates. A high percentage of chyme was observed in both species (46-65%), suggesting the consumption of easily digested materials. Also for both Fowleria species, it was observed that smaller size classes consume a higher number of small preys while larger size classes feed on larger preys. Small invertebrates such as tanaids and amphipods were more abundant in the guts of F. vaiulae and large preys of shrimps and crabs dominate the diet of F. variegata. This difference may be due to food partitioning in co-occurring species to avoid competition.

    Preliminary assessment of forest canopy and seedling condions of mangroves in oil affected areas in Taklong Island National Marine Reserve, Guimaras
    Benitez, Zaina Lei Licaniel (2007-04)
    Mangroves are important ecologically and economically in coastal areas in tropica] and sub-tropical areas in the world. However, they continue to be under threat from various human activities either directly or indirectly. The recent oil spill off the coast of southern Guimaras has brought numerous damages to these critical habitats including the mangroves in Taklong Island National Marine Reserve. This study is part of the over all Oil Spill Assessment program conducted by University of the Philippines in the Visayas following the sinking of M.T. Solar 1. This study aimed to determine the effect of oil spill on shoot development as an indicator of health conditions of trees and seedlings of selected mangroves such as Aegiceras floridum, Avicenia marina, Rhizophora apiculata Rhizophora , Rhizophora stylosa, and Sonneratia alba, in Taklong Island National Marine Reserve. Specifically, it aims to determine 1) standing leaves, 2) new leaves, 3) leaf scars of trees and seedlings. Results showed that shoot development among trees were not significantly different between oiled and unoiled sites but closer examination of species response revealed significant differences on standing leaves and new leaves only. Seedling shoot development showed a consistent significant difference among species and between sites. Aegiceras floridum and Sonneratia alba were least affected as shown by the higher number of standing leaves and least number of leaf scar while the Rhizophora spp. and Avicennia marina had the greatest number of leaf scars and least number of standing leaves. Results of this study showed that seedlings are clearly under stress and are more sensitive to oiling than trees although species response also varied individually. While tree species such as the Rhizophora spp. (e.g. R. apiculata, R. stylosa and R. mucronata) appear to be the most sensitive compared with Aegiceras floridum, Avicennia marina and Sonneratia alba. Results of this study will be useful in providing new knowledge on the evaluation of impacts of oil spills on mangroves.
