Recent Сladocera (Branchiopoda, Crustacea) in the taphocenoses of lakes in the Pechora River delta (Russia)
This paper presents the results of the hydrochemical, hydrobiological, and paleolimnological studies of 17 Arctic lakes in the Pechora River delta. Water samples and surface sediments were collected during the 2020 summer expedition to the Nenets State Nature Reserve. Based on the chemical compositi...

This paper presents the results of the hydrochemical, hydrobiological, and paleolimnological studies of 17 Arctic lakes in the Pechora River delta. Water samples and surface sediments were collected during the 2020 summer expedition to the Nenets State Nature Reserve. Based on the chemical composition of their waters, the studied lakes belong to the chloride class, sodium group II. Overall, they are characterized by shallow depths typical of this region, low mineralization (below 200 mg/L) and water hardness, as well as high dissolved oxygen levels. To assess the ecological status of the lakes, cladocerans and their subfossil remains, which have been widely recognized as reliable indicators for tracking long‐term changes in the development of freshwater ecosystems, were analyzed. A total of 23 cladoceran taxa were identified.
