Evaluation of the diversity of microcrustaceans (Crustacea, Cladocera) using sediment samples collected from Lake Neito-Malto in Yamalo-Nenets Autonomous Okrug, Russia

Detailed layer-by-layer studying of fossil remains of organisms provides an insight into the historical development of biocenoses. This paper focuses on the fossil cladoceran remains obtained from the sediment archive of Lake Naito-3 (70°12'125" N 70°22'592" E) (Yamalo-Nenets Aut...

Description
Summary:Detailed layer-by-layer studying of fossil remains of organisms provides an insight into the historical development of biocenoses. This paper focuses on the fossil cladoceran remains obtained from the sediment archive of Lake Naito-3 (70°12'125" N 70°22'592" E) (Yamalo-Nenets Autonomous Okrug, Russia) in order to model its ecological transformations. A total of 17 cladoceran taxa, mostly belonging to the family Chydoridae, were identified. The dominant species was Bosmina longirostris (Müller, 1785) widespread in all horizons of the sediment core. Using the constrained cluster analysis, four stratigraphic zones were singled out.
