Features of Zoobenthos Long-Term Dynamics in Regulated Area of Ob River

Features of Zoobenthos Long-Term Dynamics in Regulated Area of Ob River

The abundance, biomass and taxonomic structure of dominant zoobenthos species in Novosibirsk reservoir have been analyzed for the entire period of the reservoir existence. The formation of the bottom zoocenoses has been divided into four major stages. Despite significant differences in the dominant...

The formation of the bottom zoocenoses has been divided into four major stages. Despite significant differences in the dominant species composition and total biomass between the stages, the biomass of zoobenthos without shellfish had similar values (about 2,5 g/m2) over the last 50 years. In the last two decades, the dynamics of the total benthos biomass was determined by invasive gastropods Viviparus viviparus (Gastropoda, Viviparidae)http://elib.sfu-kras.ru/bitstream/2311/30330/1/05_Yanygina.pdfzoobenthosstages of formationthe Novosibirsk reservoirinvasion
