摘要
Climate va riability is an important factor leading to spatial and temporal changes in structu re and functions of plant communities.Exploring the temporal stability of communities in response to climate variability is essential for further evaluating the impacts of climate change to ecosystem functions and services.Current research on climate variability mainly focuses on plot-scale experiments(alpha scale),while how it impacts the long-term stability of a metacommunity(gamma scale) still needs further study.We analyzed the effects of climate variability on the temporal stability of plant communities at alpha and gamma scales based on a long-term observation of plant cover from 1938 to 1968 in a mixed-grass prairie in Kansas,western United States.
