Effect of Acidification on Zooplankton Communities of Small Lakes in Mountain Tundra

Small lakes in mountain tundra are studied. The typical features of their water are low pH and acid-neutralizing capacity, the predominance of sulfates over hydrocarbonates, organic matter content 1 g S/(m^sup 2^ year). The lakes zooplankton is found to have poor species composition and low quantita...

Description
Summary:Small lakes in mountain tundra are studied. The typical features of their water are low pH and acid-neutralizing capacity, the predominance of sulfates over hydrocarbonates, organic matter content 1 g S/(m^sup 2^ year). The lakes zooplankton is found to have poor species composition and low quantitative characteristics. The dominating organism complex consists of acid-tolerant species Bosmina obtusirostris and Holopedium gibberium. The water acid neutralizing capacity ANC, Ni, and N^sub tot^ are shown to have negative effect (stronger than that of pH) on the quantitative characteristics of coarse filter-feeders of the Calanoida group.[PUBLICATION ABSTRACT]
