| Popis: | Biomonitoring of stream health in the tropics still emphasize on the use of standard water chemistry methods (physicochemical variables), which require expensive and elaborate measuring apparatus. In this study, the reliability of benthic macroinvertebrates as bioindicators of freshwater streams was carried out. The study also attempted to determine the discriminating power of various biotic indices in characterizing sites across land use. Benthic macroinvertebrate samples were obtained from nine streams in Silago, Southern Leyte and were identified to family level. One-way analysis of variance was performed on various biotic indices to assess the water quality of streams based on land use. Average Tolerance Score per Taxon (ATSPT) was the only biotic index that differentiated the nine streams based on land use (P |
