人为污染向淡水生态系统的释放在很大程度上改变了全球生物多样性及其地理分布模式。然而，对于包括浮游动物等生态关键物种在内的许多群落来说，不同的群落对环境污染的反应在很大程度上是未知的。总体而言，在确定河流等流水生态系统中浮游动物群落的结构和地理分布时，分散和物种分类是两个相互竞争的过程。在精细的地理尺度上，扩散通常被认为是主导因素；然而，物种分类的相对作用没有得到很好的评估，主要是因为沿着连续流动的河流很少存在显著的环境梯度。中国北部的潮白河代表着一种罕见的水系，在那里存在着细微尺度上的显著环境梯度。在这里，我们使用高通量测序方法来表征潮白河中的复杂浮游动物群落，并测试了扩散和物种分类在确定污染梯度上浮游动物群落结构中的相对作用。我们的结果表明，浮游动物群落沿环境梯度呈现出不同的格局，与化学污染物相关的因素，如总磷和叶绿素-a，被确定为主要的驱动因素。进一步的部分冗余分析表明，物种排序压倒了扩散的影响，形成了当地浮游动物群落结构。因此，我们的结果否定了扩散假说，支持了在高污染自来水生态系统中，当精细地理尺度上存在显著的环境梯度时，由局部污染引起的物种分类在很大程度上决定了浮游动物群落结构的概念。
The release of anthropogenic pollution into freshwater ecosystems has largely transformed biodiversity and its geographical distribution patterns globally. However, for many communities including ecologically crucial ones such as zooplankton, it is largely unknown how different communities respond to environmental pollution. Collectively, dispersal and species sorting are two competing processes in determining the structure and geographical distribution of zooplankton communities in running water ecosystems such as rivers. At fine geographical scales, dispersal is usually considered as the dominant factor; however, the relative role of species sorting has not been evaluated well, mainly because significant environmental gradients rarely exist along continuously flowing rivers. The Chaobai River in northern China represents a rare system, where a significant environmental gradient exists at fine scales. Here, we employed high‐throughput sequencing to characterize complex zooplankton communities collected from the Chaobai River, and tested the relative roles of dispersal and species sorting in determining zooplankton community structure along the pollution gradient. Our results showed distinct patterns of zooplankton communities along the environmental gradient, and chemical pollutant‐related factors such as total phosphorus and chlorophyll‐a were identified as the major drivers for the observed patterns. Further partial redundancy analyses showed that species sorting overrode the effect of dispersal to shape local zooplankton community structure. Thus, our results reject the dispersal hypothesis and support the concept that species sorting caused by local pollution can largely determine the zooplankton community structure when significant environmental gradients exist at fine geographical scales in highly polluted running water ecosystems.
