Quantitative Research on Ecological Information of Recent Ostracods in East Dongting Lake

This study takes the existing ostracod species in East Dongting Lake as the research object, and obtains the biological quantitative ecological information through field ecological survey, which lays the necessary foundation for the monitoring and evaluation of the pollution degree of the lake water body, and at the same time enriches the habitat of the existing ostracod species in my country data. The recent ostracods in East Dongting Lake include 4 genera and 4 species, which are Schellencandona cf.belgica, Fabaeformiscandona fabaeformis, Cyprus kraepelini and Typhlocypris cf.rostrata. Among them, the first three appear in large numbers, but T.cf.rostrata only appears in small amounts. No local species were found. The number of ostracod species in the lake in spring is significantly less than that in autumn, which is similar to the seasonal distribution of the species in Taihu Lake. C.Kraepelini and F.fabaeformis may have stronger anti-fouling ability than S.cf.belgica and T.cf.rostrata. This shows that water heavy metal pollution has caused obvious adverse effects on the survival of ostracods, and also shows that the organism''s sensitivity to environmental pollution can be used to indicate the status of water heavy metal pollution.
