Fish Species Abundance and Species Richness in a Diverted Channel in Ilog, Negros Occidental, Philippines

Abstract

The effect of channel diversion in Ilog, Negros Occidental, was studied by comparing fish species abundance and species richness in the two river mouths, namely, Bungol Channel in Andulauan and Bocana in Lower Ilog River of the Ilog-Hilabangan River System. Data were collected for six months, from March to May 2011 for the dry season and from July to September 2011 for the wet season. Samples were collected using cast net and other indigenous gears in the locality. About 56 fish species belonging to 49 families were noted, and only three of these were introduced species. Fish species abundance was significantly different (t-test, p = 0.04), only in Bocana during the dry season. Nevertheless, fish species richness varied with season, as evidenced by the higher values observed in different river mouths. Tidal flow can significantly contribute to fish abundance and species richness, particularly during the dry season.  Read More

The Assessment of the of E-waste Management Generated from the Cellular Phones, and Laptops/ Personal Computers in the Philippines

Abstract

This study focuses on the management of e-waste generated by the disposal of personal computers, laptops, and mobile phones because of the extraordinary growth in the use of these products over the past few years by the Filipino population. The aim was to explore the current methods of disposal of the aforementioned gadgets and to gather a baseline data in terms of the disposal methods of these three electronic gadgets within the geographical boundary of Metro Manila and the suburbs of Manila, Philippines.An attempt was also made to find the level of awareness of the respondents about the hazards of e-waste. The Filipino population largely stores three electronic gadgets; namely cellular phones, laptops, and personal computers once the models become old and obsolete. The other most popular disposal method is selling the gadgets to junk shops. Very low percentage of people actually recycled their products. Sixty-nine percent of the respondents did admit that they were actually concerned about the impact of improper disposal of e-waste on human health and environment.  Read More
