A pervasive negative relationship between the species richness of an assemblage and the mean global range size of the species it contains has recently been identified. Here, we test for an effect of habitat patch size on the mean landscape-scale incidence (estimating local range size) of constituent species independent of variation in richness.

离散栖息地中物种的平均景观尺度发生率取决于斑块大小

最近发现，一个组合的物种丰富度与其所含物种的平均全球范围大小之间普遍存在负相关关系。在这里，我们测试了栖息地斑块大小对组成物种的平均景观尺度发生率（估计局部范围大小）的影响，与丰富度的变化无关。
