迫切需要综合我们关于植物对气候反应的知识状况。开放获取的数据提供了机会，可借以审查关于哪些生物群落和物种对气候驱动因素的反应最大的量化概括。在这里，我们综合了来自62种植物的162个种群的结构化种群模型的时间序列，其中大多数是来自温带生物群落的草本植物，将植物种群增长率（λ）与降水和温度驱动因素联系起来。我们期望：（1）人口对降水的反应比对温度的反应更明显，特别是在干旱的生物群落中;（2）短寿命物种比长寿命物种对气候的敏感性更高。我们发现，降水异常对λ的影响比温度大近三倍。世代时间较短的物种对气候异常的绝对响应更强。我们的结论是，关键的物种水平的特征可以预测植物种群对气候的反应，并讨论了保护规划的相关性，这种概括。植物种群增长率对年平均气温和降水量异常敏感。在这里，作者分析了来自多个生物群落的人口预测模型的时间序列，发现了短世代时间和人口对气候特别是降水异常的强烈反应之间的关系。
There is an urgent need to synthesize the state of our knowledge on plant responses to climate. The availability of open-access data provide opportunities to examine quantitative generalizations regarding which biomes and species are most responsive to climate drivers. Here, we synthesize time series of structured population models from 162 populations of 62 plants, mostly herbaceous species from temperate biomes, to link plant population growth rates (λ) to precipitation and temperature drivers. We expect: (1) more pronounced demographic responses to precipitation than temperature, especially in arid biomes; and (2) a higher climate sensitivity in short-lived rather than long-lived species. We find that precipitation anomalies have a nearly three-fold larger effect on λ than temperature. Species with shorter generation time have much stronger absolute responses to climate anomalies. We conclude that key species-level traits can predict plant population responses to climate, and discuss the relevance of this generalization for conservation planning. Plant population growth rate is sensitive to annual temperature and precipitation anomalies. Here the authors analyse time series of population projection models from multiple biomes, finding a relationship between short generation times and strong demographic responses to climate—particularly precipitation—anomalies.
