【 摘 要 】

Rivers serve as a critical element in many urban landscapes and their physical and biological conditions through time could signify the over-all effects of urbanization. In this study, two major rivers of highly-urbanized Cebu City, Philippines, namely Butuanon and Lusaran, were assessed in terms of diversity of macroinvertebrates species and water quality status. A total of 1,442 macroinvertebrate individuals were found in both rivers representing a total of 39 genera belonging to phyla Arthropoda, Mollusca and Annelida. Lusaran River harbors higher diversity of macroinvertebrates than Butuanon River and the species’ Index of Similarity of the two rivers is 38.90%. The dominant species in Lusaran River are the pollution-sensitive caddisflies (Hydropsyche sp.) with relative abundance of 40.98%. On the other hand, the non-biting-pollution-tolerant midges (Chironomus sp.)
