Stream ecology and macroinvertebrates

WebIn the upper reaches of a river, shredders and collectors make up a large percentage of total macroinvertebrates due to the excess presence of coarse plant matter. In the midreaches of a stream or river, where more light is available, there is an increase in the proportion of grazers due to the presence of periphyton. WebAs the link between organic matter (resulting from primary production) and fish, and because of their common and diverse presence in streams, macroinvertebrates are of key interest in the study of stream ecology and can be used as key indicators of stream habitat and water quality.
