Zooplankton from two types of drinking water sources(10 reservoirs and 10 rivers) in Zhejiang province were sampled during four seasons from July,2009 to April,2010.101 species of zooplankton(60 Rotifera,24 Cladocera and 17 Copepoda) were found.Brachionus angularis(Rotifera) and Bosminopsis deitersi(Cladocera) dominated in reservoirs,whereas Polyarthra trigla(Rotifera) and Bosmina longirostris(Cladocera) dominated in the rivers,Thermocyclops(Copepoda) dominated both in reservoirs and rivers.Highest assemblage concordance was observed between cladocerans and copepods in the reservoirs with higher water transparency across one year(P<0.01),while the lowest level of concordance was detected between copepods and rotifers.In summer,autumn and winter,there had positively relationships between cladocerans and copepods in the rivers with lower water transparency(P<0.05).Strong relationships among zooplankton groups were found in Autumn for the reservoirs and in Summer for the rivers.There were opposite variations in the species diversity both rotifers and crustaceans underlying the transparency gradient of the drinking water sources.
