这篇讲什么
该研究整合物种特异性分布区迁移速度与物种分布模型,预测了全球18%的维管植物在2081至2100年的分布变化,发现7%至16%的物种将面临高灭绝风险,且主要由气候导致的栖息地丧失而非扩散限制驱动。

plant diversity but don’t reduce extinction risk Full article and list of author affiliations: https://doi.org/10.1126/ science.aea1676 Junna Wang*, Brunno F. Oliveira, Frances C. Moore, Daniel J. Kozar, Yongshuo Fu, Xiaoli Dong* INTRODUCTION: Anthropogenic climate change is reshaping where plants can live. As temperature and precipitation patterns shift, many species are moving to stay within suitable environmental conditions. Predicting how these range shifts will affect future biodiversity requires knowing both where suitable habitats will occur and whether species can reach them. The latter is challenging because dispersal abilities differ widely among species and depend on landscape structure, anthropogenic barriers, and climatic conditions. …
