军山湖、青山湖和瑶湖春夏季节浮游甲壳动物的群落结构及其与环境因子的关系
Community structures of crustacean zooplanktons and their correlation with environmental factors during spring and summer in Junshan, Qingshan and Yaohu lakes
摘要
Abstract
The community structure of crustacean zooplanktons in three lakes (Junshan,Qingshan and Yaohu) in Nanchang,Jiangxi Province was investigated from March to August 2016.The results showed that 14 species of crustacean zooplanktons were identified in the three lakes,eight species out of which belonging to Cladocera and six species belonging to Copepoda.The density of crustacean zooplankton in Lake Junshan,Lake Qingshan and Lake Yaohu ranged 0.8-24.9,0.3-18.7,and 5.9-47.9 ind·L-1,respectively.The density of crustacean zooplanktons in Lake Yaohu was significantly higher than that in Lake Junshan (P =0.003) and Lake Qingshan (P＜0.001).The eutrophic species,Diaphanosoma sp.,Moina micrura,and Bosmina sp.,were the dominant ones in the three lakes in summer,whereas Daphnia galeata was the dominant species in Lake Junshan in spring.Results from redundancy analysis showed that water temperature,chlorophyll a,and pH determined the community structure of crustacean zooplanktons in the three lakes.In addition,the community structure of crustacean zooplanktons in Lake Qingshan and Lake Yaohu located on the outskirts of the city were closely related to nitrogen and phosphorus concentrations.关键词
