摘要
We present a framework to measure the strength of environmental filtering and disequilibrium of the 物種 composition of a local community across time, relative to past, current, and future 氣候s. We demonstrate the framework by measuring the impact of 氣候 change on New World 森林s, integrating data for 氣候 niches of more than 14 000 物種, community composition of 471 New World 森林 plots, and observed 氣候 across the most recent glacial-interglacial interval. We show that a majority of communities have 物種 compositions that are strongly filtered and are more in equilibrium with current 氣候 than random samples from the regional pool. Variation in the level of current community disequilibrium can be predicted from Last Glacial Maximum 氣候 and will increase with near-future 氣候 change.
