The Community Structure and Environmental Correlation of Zooplankton in Xiaoheli River Reservoir during Spring

Hongxian Yu

Abstract

The zooplankton species composition and relation to the environment were studied in 7 sampling sites in Xiaoheli River Reservoir in Heilongjiang Province during May of 2012.A total of 15 zooplankton species were recorded including 6 species of protozoa,8 species of rotifer and 1 species of cladoceran.The zooplankton abundance was shown to be ranged from 77 ind.·L-1 to 683 ind..·L-1.There were the peak Shannon Wiener diversity ind.ex(1.94) in sampling site 5 and the minimal value(1.28) in sampling site 7.The Pearson correlation analysis revealed that water depth,dissolved oxygen levels(DO) and the concentrations of TN were closely correlated with the zooplankton abundance(P0.05).
