| Abstract: | On the basis of long-term monitoring of macrozoobenthos in the Volgograd Reservoir, the causes of changes in its species composition were analyzed and invading species were identified. During the first 20–25 years after construction of the reservoir, invading species appeared at a rate of 0.4 species per year. In the subsequent years, this rate increased to one species per year due to spontaneous expansion of species and the remote effect of their introduction. |
