Zooplankton make the secondary level in aquatic ecosystems and provide a ready source of food for secondary consumers. Hence any fluctuation in their population will directly affect the food webs, and eventually the whole ecological system. This study was carried out along a main branch of Diyawanna Oya, during the period of February to July, 2003....
Macroinvertebrates have been identified as excellent indicators of stream/ wetland health as they respond rapidly to environmental changes and provide short to medium term pollution history records. Current study was aimed to develop a Macroinvertebrate-based Index of Biotic Integrity (M-IBI) which is a new approach to monitor stream/wetland health...
