Fresh waters have seen the largest decline in biodiversity of any ecosystem, with lotic ecosystems particularly impacted by human activities. The main drivers of environmental change relate primarily to agriculture, urbanization, and industrial production that have resulted in severe habitat degradation in streams and rivers.
The ecosystem of a river is the river viewed as a system operating in its natural environment, and includes biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. River ecosystems are prime examples of lotic ecosystems. Lotic refers to
LOTIC ECOSYSTEMS. Rivers and streams rarely display the vertical stratification patterns found in standing bodies of water because of their turbulent flow. Although slight differences in temperature can exist between the surface and bottom waters of deep lotic systems, the greatest changes take place as water moves.

13 Nov 2016 Full-text (PDF) | The freshwater ecosystems are generally classified into two major groups as, lentic and lotic ecosystems. The term Lentic ecosystems is given to standing water bodies or still water bodies. The LENTIC Ecosystems includes all standing water bodies like Lakes, ponds, swamps or bogs
