Zooplankton in water bodies of coastal marshes in Malozemelskaya tundra

Abstract

The composition and structure of zooplankton in small water bodies (ponds and puddles) of Pechora Bay coastal marshes have been studied. The investigated water bodies are confined to three ecotopes (low, medium, and high marshes), distinguished on the coastal strip according to the degree of soil salinity and vegetation quality along the ecological profile perpendicular to the coast. It has been revealed that the species composition and zooplankton abundance are dependent on the type of ecotope and water salinity. The trophic structure of the community shows the difference in food resources between the studied ecotopes.
