Abstract

Lentic water bodies are amongst the most threatened wetland habitat types as anthropogenic disturbances have significantly influenced the structure and function of aquatic ecosystems. This study compared the seasonal variations of macro-invertebrate diversity and analysed the physiochemical parameters to study the influence of surrounding land use on the ecosystem of Adha Lake. Macro-invertebrate abundance in the lake was used as an indicator to assess the effect of surrounding land use. The lake was categorised into four major zones namely agriculture zone, forest east zone, catchment zone, and forest west zone. Sampling was carried out along the littoral zone of the lake. Physiochemical variables were collected for both the seasons. Chironomidae and Baetidae families were the most dominant macro-invertebrates in the lake. The least families encountered were Acrididae, Aeshnidae, Tabanidae, Hydrophilidae, and Libellulidae during monsoon season, and Simuliidaeand Culicidae for post-monsoon season. There was no significant difference in Shannon Wiener’s Diversity Index for monsoon and post-monsoon seasons, p> .05. pH, salinity, conductivity, total dissolved solid, and water temperature had negative correlation with diversity and richness; however, total dissolved solid, water temperature, and pH had positive association with taxon evenness. The HKH-bios index and NHBL index indicated that the lake is polluted which could be attributed to discharge from the paddy fields. Restoration and protection of Adha Lake as White-bellied heron’s habitat may need significant conservation and advocacy measures.
