Distribution of Anuran Species in Loboc Watershed of Bohol Island, Philippines Reizl P. Jose gzl_4@yahoo.com Bohol Island State University Philippines 11:36 – 11:55 August 20 – Ballroom C The Philippines is rich in biodiversity and Bohol Island is among the many places in the country requiring attention for conservation efforts. For this reason, a surveyo f anurans was conducted in Loboc Watershed, the forest reserve in the island. Different sampling techniques were used. Three transect lines was established and were positioned perpendicular to water bodies parallel to the existing trails. A 10x10 meter quadrat size was established along each transect line. A visual encounter technique was used along each established quadrat and identification was done using a field guide.Fifteen species of anurans were recorded. One species belong to families Bufonidae (Bufomarinus) and Megophryidae (Megophryisstejnegeri); two to family Microhylidae (Kalophrynuspleurostigmaand Kaluolapicta); six familyRanidae(Fejervaryacanc rivora, Limnonectesleytensis, Limnonectesmagnus, Platymantisguentheri, Playmantiscorrugatus, and Ranagrandocula) and five Rhacophoridae (Nyctixalusspinosus, Polypedatesleucomystaxleucomystax, Polypedatesleucomystaxquadrilineatus, Rhacophorusappendiculatusand Rhacoporuspardalis).The disturbed nature of the area still recorded endemic and threatened species. This suggests that forests and critical habitats in the area need to be protected and conserved.

Dissolved Metals Present in Wastewater Effluents Among Passenger Vessels in the Philippines Ma. Lona T. Torrigue John B. Lacson Foundation Maritime University-Arevalo Philippines 11:51 – 12:10 August 20 – Ballroom C There is little or no information available in the literature about the dissolved metals present in wastewater effluents among passenger vessels most especially in the Philippines. Thus, this study serves as baseline information on the presence of dissolved metals in greywater effluents from the passenger vessels in the Philippines. The study quantified the dissolved metals such as copper, nickel and zinc as listed in the priority pollutants of U.S. EPA. These metals were measured by the flame atomic absorption spectrometer (FAAS) and their means was determined for each sample. Three vessels were sampled and three liters were collected from each vessel. Copper, nickel and zinc (µg/L) was very high as compared to the standard values set by the Alaska Department of Environmental Conservation. The highest average value of copper was 145. 17 µg/L, 149.73 µg/L for nickel, and 754.6 µg/L for zinc.There is a significant difference (p < .05) of dissolved metals among the passenger-vessels sampled. Since metals can accumulate in the living tissues, this study stresses the importance of wastewater treatment facilities in passenger vessels to prevent or to minimize metal contamination in the marine environment.
