Widespread Effects of Climate Change on Local Plant Diversity.

摘要: Summary Human activity has sent many measures of biodiversity into long-term decline, and there are suggestions that the sheer scale this impact is sufficient to consider modern era as a geological epoch its own, known “The Anthropocene” [ 1 ]. However, recent meta-analyses show local alpha diversity often stable or slightly increasing 2 , 3 4 Here, we (species richness) plants found in quadrats transects increased most cooler regions world have experienced highest absolute changes (i.e., either direction) climate. The greatest statistical support for effects precipitation change. On average, declined (−4.2% per decade) third sites lowest change but (+10.8% with These results suggest “perturbation” communities during climatic transitions increases average number species, at least temporarily, an effect likely remain important climate continues.
