元共生性理论预测，区域和地方的进程结构社区的相对重要性将随着时间的推移而改变，因为社区大会的启动。确定这些过程对物种和性状多样性的影响，在继承至今仍然在很大程度上未解决的metacrobiity生态学，但可以赋予一个更好的机械理解的社会集会。要测试的理论预测的结构化社区的重要性越来越大的本地进程在继承阶段的metacompatiities，我们评估了鱼类物种和性状多样性在三个池塘metacompatiities进行二次继承海狸（加拿大蓖麻）的干扰。不同年龄的池塘社区和参考流的分类和性状多样性的影响过程进行了对比。相反的预测，当地环境变得不那么重要，在结构社区继承，但施加更强的影响性状排序。β多样性和性状丰富度下降，而对物种丰富度或性状分散度没有影响。在老生境的特征过滤可能是一个更大，更深的池塘生态系统的后期演替的特点。与池塘中观察到的这些影响相反，当地环境主要是溪流中的物种和性状多样性。区域和当地的过程中结构化的鱼组合在每个池塘metacrobility的相对重要性的分析表明，栖息地的年龄和连通性更重要的是结构化社区的环境，但区域和规模依赖的贡献。总之，这些研究结果强调，区域和当地的进程可以不同地影响演替后居镶嵌的分类和性状多样性。
Metacommunity theory predicts that the relative importance of regional and local processes structuring communities will change over time since initiation of community assembly. Determining effects of these processes on species and trait diversity over succession remains largely unaddressed in metacommunity ecology to date, yet could confer an improved mechanistic understanding of community assembly. To test theoretical predictions of the increasing importance of local processes in structuring communities over successional stages in metacommunities, we evaluated fish species and trait diversity in three pond metacommunities undergoing secondary succession from beaver (Castor canadensis) disturbance. Processes influencing taxonomic and trait diversity were contrasted across pond communities of different ages and in reference streams. Counter to predictions, the local environment became less important in structuring communities over succession but did exert a stronger effect on trait sorting. Beta diversity and trait richness declined over succession while there was no influence on species richness or trait dispersion. The trait filtering in older habitats was likely a response to the larger and deeper pond ecosystems characteristic of late succession. In contrast to these observed effects in ponds, the local environment primarily structured species and trait diversity in streams. Analyses of the relative importance of regional and local processes in structuring fish assemblages within each pond metacommunity suggests that habitat age and connectivity were more important than the environment in structuring communities but contributions were region and scale-dependent. Together, these findings highlight that regional and local processes can differentially influence taxonomic and trait diversity in successional metacommunity mosaics.
