Influence of Abiotic and Trophic Factors on the Daily Horizontal Migration of Zooplankton in the Littoral Zone of the Novosibirsk Reservoir

Abstract

Daily changes in water temperature, hydrochemical characteristics, composition, and structure of phyto- and zooplankton in the open and overgrown littoral parts in Berdsk Bay of the Novosibirsk Reservoir have been analyzed. The relationship between the number of some groups and species of zooplankton and factors of the environment is considered. It is shown that water temperature and trophic relationships play the main role in the daily dynamics of phyto- and zooplankton abundance in the littoral zone.
