The decreasing capacity of area to predict species richness on small islands (the small‐island effect; SIE) seems to be one of the few exceptions of the species–area relationship. While most studies have focused on how to detect the SIE, the underlying ecological factors determining this pattern remain largely unexplored. Here, we evaluate one of the few mechanisms proposed to explain the SIE, the subsidized island biogeography hypothesis, which posits that marine productivity around small islands may alter their expected species richness.

补贴岛屿生物地理学假设的全球检验

面积预测小岛上物种丰富度的能力下降（小岛效应； SIE）似乎是物种与面积关系的少数例外之一。尽管大多数研究都集中在如何检测SIE上，但决定这种模式的潜在生态因素仍未得到充分探索。在这里，我们评估为解释SIE而提出的为数不多的机制之一，SIE是受补贴的岛屿生物地理学假说，该假说认为，小岛屿周围的海洋生产力可能会改变其预期的物种丰富度。
