Geographical distribution of zooplankton biodiversity in highly polluted running water ecosystems: Validation of fine-scale species sorting hypothesis.

ABSTRACT: Dispersal, rather than species sorting, is widely recognized as the dominant driver for determining meta-community structure at fine geographical scales in running water ecosystems. However, this view has been challenged by a recently proposed "fine-scale species sorting hypothesis," where community structure can be largely determined by an environmental gradient formed by local pollution at fine scales. Here, we tested this hypothesis by studying community composition and geographical distribution of metazoan zooplankton in a heavily polluted river-the North Canal River in the Haihe River Basin, China. Analysis of similarity (ANOSIM) showed that the community composition of metazoan zooplankton differed significantly (p = .001) along the environmental gradient. Ammonium (NH4-N) was the le
