Taxonomic composition of zoobentos of “Severnyi Volos” and “Yuzhnyi Volos” lakes and its change with depth
Abstract
Species composition of the zoobenthos of “Severnyi Volos” and “Yuzhnyi Volos” which are part of the National Park “Braslavskie Ozera”, was established. There were registered 39 species and forms, which belong to 3 types: arthropods, annelids and mollusks. In both lakes the most common were the chironomid larvae. The number of taxa was higher in the Yu. Volos, which has greater transparency and high oxygen content in the hypolimnion. Despite the connection that exists between the lakes, bentofauna match only with a 39.5 % agreement. In the zoobenthos composition of the Yu. Volos was registered 2 relic crustaceans: Pallasiopsis and Monoporeia. Only one relict species was found in the S. Volos (Pallasiopsis). The total number of species and zoobenthos composition varies with depth. In both lakes there is a diversity increase from the littoral to the temperature jump zone, where is a maximum. There is a gradual depletion of fauna in profundal zone of the S. Volos, which is probably due to a lack of oxygen. In the Yu. Volos the number of inhabited taxa increases to the maximum depths under favorable oxygen regime.
