Climate warming is triggering a steady increase in the mean thermal optimum of plant communities. We show that this increase reflects the dieback of cold-adapted species rather than the arrival of warmer-adapted species, with negative effects on local diversity and mutually cancelling effects on community heterogeneity.

灭绝驱动气候变化引起的森林植物群落重组

气候变暖正在引发植物群落平均最适温度的稳步上升。我们表明，这种增加反映了适应寒冷的物种的枯死，而不是适应温暖的物种的到来，对当地多样性产生了负面影响，并对群落异质性产生了相互抵消的影响。
