The Lake Pizanets (Republic of Karelia, Russia) – a new site for establishingthe protected area
A survey of the morphological and hydrological characteristics of the lake and analysis of the species composition, abundance, and biomass of phytoplankton, phytoperiphyton, zooplankton, and zoobenthos were carried out as a part of the complex study for establishing a new protected area “Lake Pizane...

A survey of the morphological and hydrological characteristics of the lake and analysis of the species composition, abundance, and biomass of phytoplankton, phytoperiphyton, zooplankton, and zoobenthos were carried out as a part of the complex study for establishing a new protected area “Lake Pizanets”.

The trophic status of the lake, its saprobity, and the significance of particular communities and bioindication indices were estimated. The species composition and dominant species of the studied communities of the lake were quite typical for freshwater bodies of the region. Despite the fact that the abundance and biomass of macrozoobenthos turned out to be lower than in other lakes of Eastern Fennoscandia, generally, the abundance and biomass of phytoplankton, phytoperiphyton, zooplankton, and zoobenthos evidenced on relatively high degree of their development in the lake Pizanets, as well as on their activity and stability.
