The small‐island effect (SIE) describes a different relationship between island area and species richness on smaller compared to larger islands. The pattern has recently gained widespread support. However, few studies have attempted to identify the actual mechanisms driving the SIE. Here, we use a phylogenetic community framework to study the SIE, based on the assumption that if the dominant assembly processes differ between small and large islands, patterns of phylogenetic community structure should shift across the area and habitat diversity gradient.

通过系统发育群落生态学来揭示小岛效应

小岛效应（SIE）描述了小岛和大岛上岛屿面积和物种丰富度之间的不同关系。这种模式最近得到了广泛的支持。但是，很少有研究试图确定驱动SIE的实际机制。在此，我们基于一个假设，即如果小岛屿和大岛屿之间的主要装配过程不同，则系统发育群落结构的模式应在整个地区和栖息地多样性梯度上转移，因此我们使用系统发育群落框架来研究SIE。
