Abstract

The functional–trophic structure of benthic invertebrates of the Krutaya Kacha River is studied. A visual analysis of food boluses and an analysis of FAs of the dominant species of macroinvertebrates are conducted. The results obtained for the Krutaya Kacha River confirm the high importance of benthic invertebrates in the decomposition of allochthonous organic matter. The results on the ratio of functional–trophic groups of invertebrates of the Krutaya Kacha River are consistent with the River Continuum Concept (RCC).
