Climate variability threatens to destabilize production in many ecosystems. Asynchronous species dynamics may buffer against such variability when a decrease in performance by some species is offset by an increase in performance of others. However, high climatic variability can eliminate species through stochastic extinctions or cause similar stress responses among species that reduce buffering. Local conditions, such as soil nutrients, can also alter production stability directly or by influencing asynchrony. We test these hypotheses using a globally distributed sampling experiment.

气候与当地环境结构的不同步与草地初级生产的稳定性

气候多变性威胁到许多生态系统的生产稳定。当某些物种的性能下降被其他物种的性能提高所抵消时，异步物种动力学可能会缓冲这种可变性。但是，高的气候变异性可以通过随机灭绝消除物种，或在物种之间引起类似的胁迫反应，从而减少缓冲。当地条件（例如土壤养分）也可以直接或通过影响异步性来改变生产稳定性。我们使用全球分布的抽样实验来检验这些假设。
