| 摘 要： | 为了解大鹏澳浮游纤毛虫时空分布特征及与环境因子间的关系,于2014年冬季、春季、夏季和秋季对大鹏澳海域进行了浮游纤毛虫的调查,并采用多元分析方法研究了环境因子对其的影响。结果显示,共检出纤毛虫31种,隶属于4纲、8目、18属。纤毛虫平均丰度为1 487个·L-1(10~5 040个·L-1),以砂壳目(Tintinnida)、急游目(Stombidiid)和环毛目(Cyclotrichida)为主。浮游纤毛虫群落结构时空差异较大。浮游纤毛虫丰度在春季最高,冬季最低;种类在夏季最多,春季最少。此外,在鱼类网箱养殖区浮游纤毛虫丰度最高,而在王母河入海口最低。通过冗余分析(redundancy analysis,RDA)发现,大鹏澳浮游纤毛虫群落结构差异主要与水体营养盐水平、温度和叶绿素a含量有关,且在不同季节有不同的主要影响因子。

| Abstract: | To reveal spatial and seasonal pattern of planktonic ciliate communities and its relationship with environmental variables,we investigated the planktonic ciliate composition,abundance and response to environmental changesuring four seasons of 2014 in Dapeng Cove,the South China Sea.A total of 31 species helonging to eight orders were identified,11 of which were dominant spe-cies.The average abundance of ciliate was l 487 ind·L-1(10-5040 ind·L-1),and Tintinnida,Strombidium and Cyclotrichida were the most abundant in terms of number and ahundance.Planktonic ciliate communities showed a distinct seasonal pattern of ciliate abundance and a clear seasonal shift of the taxonomic composition.The highest number of ciliate species occurred in summer,whereas the highest abundance peaked in spring,mainIY due to the stromhidium.Spatially,planktonic ciliate was more abundant and diverse in the cage fish ulture area and oyster-algae mixed culture area,but the lowest abundance and species occurred in the estuary of Wangmu River.Multivariate analvses illustrate that ciliate abundance was significantly correlated with water temperature,nutrient level and chlorophyll-a concentration.Moreover,the dominant abiotic environmental factors affecting the seasonal pattern of ciliate commu-nities were different between seasons. |
