Climate change is leading to large‐scale shifts in species’ range limits. Mangroves, for example, are encroaching into saltmarshes at numerous tropical–temperate transition zones. However, mangrove expansion varies geographically, in large part because mangroves might not be fully occupying their fundamental niches across their range limits. Here we characterize and compare the fundamental versus realized thermal niches of two mangrove species found near their northern range limits on both coasts of North America.

北美红树林基本生态位与已实现生态位的差异

气候变化正在导致物种范围限制的大规模变化。例如，红树林在许多热带-温带过渡带都侵入了盐沼。但是，红树林的扩张在地理位置上有所不同，这在很大程度上是因为红树林可能无法在其范围限制内完全占据其基本壁ni。在这里，我们表征并比较了在北美两个海岸的北部范围限制附近发现的两种红树林物种的基本生态位和已实现的热生态位。
