Response of rotifer community to environmental changes in five shallow lakes in the middle reach of Changjiang River, China
摘要
Abstract
We evaluated the response of a rotifer community to environmental changes in five shallow lakes in the middle reach of the Changjiang (Yangtze) River in summer and autumn 2010. These five lakes differed in trophic status and rotifer community structure. Twenty-nine rotifer species were collected
of which Keratella cochlearis
Polyarthra dolichoptera
and Trichocerca elongate were dominant. The mean density
Shannon-Wiener diversity
and equitability among the five lakes differed significantly (P<0.05). The mean rotifer density was positively correlated with trophic state. The diversity was higher in lakes with high macrophyte coverage. The composition of rotifer species was closely associated with the trophic gradient. Five environmental variables
Secchi depth
conductivity
TN
NH4-N
and TP
significantly affected the composition of rotifer species. Keratella quadrata
Brachionus calyciflorus
and B. forficula were more common in eutrophic conditions. Our results suggest that eutrophication has a significant influence on the rotifer community structure and highlight the potential for using rotifer community structure as an indicator of trophic status in subtropical lakes.
