Abstract
En 中文
For improved predictions of the redistribution of species under climate change, there is a need to better understand how interactions among multiple abiotic drivers affect species distributions. We examined whether occupancy patterns of forest plant species change consistently along geographic and macroclimatic gradients. We further tested whether these changes co-vary with species’ edaphic niche widths—specifically, whether niche widths contract as occupancy declines. Finally, we assessed ehether changes in occupancy and niche widths depend on species’ climatic and edaphic niche optima.
