Macrofloral diversity of Bulabog-Putian Natural Park, Dingle, Iloilo, Philippines
(Silliman University, 2010-01)
Macrofloral species richness, relative density, relative abundance and diversity index of the protected forest and riverine ecosystems of Bulabog-Putian Natural Park, Dingle, Iloilo, Philippines were determined employing the modified quadrat method. There were 68 families, 170 genera, and 218 plant species listed in the entire study area of 0.16 hectare. The riverine ecosystem had a higher species richness (S=137) compared with the protected forest ecosystem (S=126). The top three major families observed in the protected forest ecosystem were Euphorbiaceae, Moraceae, and Annonaceae families and for the riverine ecosystem they were the Moraceae, Poaceae, Euphorbiaceae and Papilionaceae families. Plant genera that belong to the families Euphorbiaceae and Annonaceae dominated the protected forest ecosystem and the plant genera belonging to families Poaceae and Cyperaceae dominated the riverine ecosystem.
Relative abundance in the herb-dominated riverine ecosystem forest ecosystem with values of 43,466 and 7,007 individuals, respectively. Computed diversity index was higher in the riverine ecosystem (H’=3.30) than the protected forest ecosystem (H’=2.69), both categorized as areas of moderate level of species diversity. In the entire study area, 28 (12.84%) plant species are known to have threatened conservation status; three of these are critically endangered, namely kamagong (Diospyros philippensis Desr.) Gurke), prickly narra (Pterocarpus indicus Willd. forma Echinatus), and red lauan (Shorea negrosensis Foxw.). Endemic plant species were inventoried that need to be conserved and protected.
This study provides comprehensive baseline information on the macrofloral diversity of Bulabog-Putian Natural Park. Data gathered from this study will enhance knowledge on biodiversity for the local or national government to implement strong conservation and protection programs for the endemic and indigenous plant species in their natural habitat and to prevent biodiversity loss that may be aggravated by climate change....

Physico-chemical assessment of the Jalaur River system, Iloilo, Philippines
(Silliman University, 2010-01)
The Jalaur River System was studied for the quality of its water because water quality is a significant and powerful determinant of the health of aquatic ecosystems. This study aimed at investigating the physico-chemical parameters, nutrient load, heavy metal concentrations and pesticide residues of the Jalaur River system. One of the purposes of this study was to develop a database on the seasonal changes in these river characteristics.
Quantitative samples of water, sediments, algae and fish were collected and analyzed during the rainy season (July-September 2009) and the dry season (January-March 2010) from five sampling stations representing upstream, midstream and downstream sections of the 123-kilometer long river. Based on the water quality standard and water classification adopted by the DENR, the Jalaur River stretch can be classified as class C and D. Class C water is for propagation and growth of aquatic resources while class D water is for agriculture, irrigation, livestock watering, and industrial cooling and processing.
The detected levels of metal contamination, mainly Cr, and Pb, in sediments of Jalaur River were found to exceed the geochemical background or threshold levels. Lead and chromium were also detected in filamentous algae (lumot), Azolla, and tilapia (Oreochromis niloticus) sampled at Moroboro sampling site. No organochlorines, organophosphates, carbamates, and pyrethroids pesticides were detected at the detection limit of the analyses for both water and sediment samples.
The deterioration in the physico-chemical quality and rise in the nutrient levels observed in this study is alarming, and periodic monitoring and preventive measures are required to save the aquatic system of eutrophication. Heavy metal contamination of bottom sediments, algae and fish samples is also a cause for alarm because these heavy metals pose threats to human health. The finidngs have important implications for the development of effective water management strategies and as guide to remediation of efforts for the Jalaur River system....
