Community structure of mayflies (Insecta: Ephemeroptera) in tropical streams of Western Ghats of Southern India

The main objective of this study was to evaluate the community structure order Ephemeroptera in Southern Western Ghats ecoregion along with Principal Component Analysis (PCA) and Canonical Correspondence (CCA) from 2017 2018. Ecological parameters estimated at each collecting site were pH, dissolved oxygen, biological oxygen demand, hardness alkalinity. This research investigation carried out 30 streams Palni Cardamom hills India. With PCA examination, sites like Dhobikana, Fern hill Poomparai are plotted far apart not supported by ecological other sites. Dhobikana is exceptionally contaminated light fact that dhobis associated washing garments so cleanser contamination prevalent around there. In cardamom hills, Santhamparai near bridge Nayamakkadu left indicating they physico-chemical parameters, mainly due pollution. From CCA results, it discovered Baetis species favor β-mesosaprobic habitat Indialis badia inclines toward high altitudinal region. outcomes, presumed alkalinity essential components administering mayfly structure.
