Stream Periphyton community: A brief review on Ecological importance and Regulation
Publication Date : 02/10/2017
Periphyton communities serve as vital component of stream ecosystems. These play an intermediate role between the overlaying water column and the substrate beneath and allow periphyton to affect both environments. These also act as a link in the transfer of material and energy along different food chains of streams and also act as significant bioindicators of water quality and ecological health of streams. Growth of these communities is regulated by a number of ecological factors being natural or having a certain degree of anthropogenic contribution. This brief review highlights some chief factors namely nutrients, flow velocity and various physico-chemical limnological parameters which regulate the periphyton community in streams.
