Community assembly has been an important topic in ecological research and theory for over a century. Recently, restoration ecologists have emphasized the use of community assembly rules, such as environmental filtering, to better inform management actions. Although there has been a strong call for the use of community assembly rules in terrestrial restoration ecology, few studies have examined their potential use in providing habitat benefits such as food resources to native species in large‐scale managed aquatic ecosystems. In this study, we found evidence of deterministic community assembly mechanisms in zooplankton communities in floodplain and seasonally inundated off‐channel habitats in California’s Central Valley. Additionally, we found that all sampled off‐channel floodplain habitat types had similar zooplankton communities and that assembly in floodplain habitats was governed by variables associated with increased water residence time. This study is the first to determine community assembly rules in floodplain‐river ecosystems in order to assist managers in providing floodplain food‐web benefits to native fish and wildlife species at the landscape scale.

了解受控洪泛区食物网中的社区集会规则

一个多世纪以来,社区集会一直是生态学研究和理论研究的重要课题。最近,恢复生态学家已强调使用社区组装规则(例如环境过滤)来更好地告知管理措施。尽管在陆地恢复生态学中强烈要求使用社区集会规则,但很少有研究检验其在为大规模管理的水生生态系统中的原生生物提供栖息地益处(如食物资源)方面的潜在用途。在这项研究中,我们发现了加利福尼亚泛滥平原的浮游动物群落和加利福尼亚中央山谷的季节性淹没河外生境中确定性的群落聚集机制的证据。另外,我们发现,所有采样的河外洪泛区生境类型都具有相似的浮游动物群落,并且洪泛区生境中的组装受与增加水停留时间相关的变量支配。这项研究是第一个确定洪泛河流生态系统中的社区集会规则,以帮助管理人员在景观尺度上为当地鱼类和野生动植物物种提供洪泛食物网的好处。
