在淡水中，对干旱等极端事件如何改变生物多样性和生态系统功能的大多数生物地理理解源于对生态群落、完好和受干扰地点之间或沿压力梯度的静态空间比较。随着时间的推移，干旱对生态社区发展的影响仍然没有得到很好的解决，关于社区结构和功能的平行趋势的信息尤其匮乏。从理论上讲，干旱可能会逐渐消除物种和功能特征，使群落在分类和功能上越来越多地嵌套在先前存在的对应群落的子集上。或者，干旱可能会创造新的生态位机会，产生物种和特征的持续更替，或者只是限制自然群落的演替。
In fresh waters, most biogeographical understanding of how extreme events such as drought modify biodiversity and ecosystem functioning derives from static, spatial comparisons of ecological communities, between intact and disturbed sites or along stress gradients. Impacts of drought on the development of ecological communities over time remain poorly resolved, with information on parallel trends in community structure and function particularly scarce. In theory, drought could progressively eliminate both species and functional traits, rendering communities increasingly taxonomically and functionally nested subsets of their pre‐existing counterparts. Alternatively, drought could create new niche opportunities, producing a continuous turnover of species and traits, or simply constrain natural community succession.
