Abstract:

Biomonitoring of the Ephemeroptera (Family: Baetidae) was undertaken at species level in the Tamiraparani (Tirunelveli) and Vaigai (Theni) river basins of southern India. A total of 1,359 baetids were collected from three times from ten sampling sites, representing an environmental gradient. The mesohabitats of sixteen Baetidae species was described and their responses to environmental degradation and water chemistry were evaluated by means of species richness and abundance and the data was subjected to multivariate analysis (Canonical Correspondence Analysis), in order to assess their potential capacity as indicators of these impacts. Most species were found predominantly associated with stony substrates, but some were associated with grasses, and two species were found predominantly in lentic water bodies. Species distributions were influenced by the environmental gradient. Based on the CCA ordination, pristine and the most impaired areas were identified for each spices so as were found in therefore enabling us to establish the sensitivity of each species.
