Despite the increasing scientific interest in distance decay of compositional similarity in ecology, the scale dependence of geographical versus environmental control on distance decay of biological communities has not been properly addressed so far. The present work highlights the relative importance of niche‐based processes versus dispersal limitations on distance decay patterns of epilithic bryophyte assemblages at different spatial scales.

苔藓植物集合中距离衰减的驱动因素在多个空间尺度上：分散性限制还是环境控制？

尽管对生态学中组成相似性的距离衰减的科学兴趣越来越高，但到目前为止，地理与环境控制对生物群落距离衰减的尺度依赖性尚未得到适当解决。目前的工作强调了基于生态位的过程相对于不同空间尺度上石器苔藓植物组合的距离衰减模式的扩散限制的相对重要性。
