Positive relationships between island size and species richness have been found for oceanic and non‐oceanic islands. However, the effect of isolation, also predicted by island‐biogeographical theory, seems challenging to test. Species‐specific mechanisms drive the perception of distance and space for animals, and therefore isolation patterns are masked when described at the community level. We used epiphytic plants (canopy islands) and their spider communities to study how functional group and species‐specific use of space modifies the effect of island‐level predictors on species richness.

附生植物上蜘蛛群落的岛屿生物地理格局取决于功能组之间空间的差异利用

已发现大洋和非洋洋岛屿的岛屿大小与物种丰富度之间存在正相关关系。然而，岛屿生物地理学理论也预测到隔离的效果似乎很难检验。特定于物种的机制推动了动物对距离和空间的感知，因此，在社区一级对隔离模式进行掩盖。我们使用附生植物（冠层岛屿）及其蜘蛛群落来研究功能组和特定物种对空间的利用如何改变岛屿级别的预测因子对物种丰富度的影响。
