Short-term instabilities and long-term community dynamics

摘要: Competition in a temporally variable environment leads to sequences of short-term instabilities that some cases are the mechanism long-term coexistence; other they promote instability. Recent work associates stability with positive relationship between environmental and competitive effects population growth rates buffered against jointly unfavorable events. Buffered arise from subdivision over life-history stages, microenvironments or phenotypes. A distinct but related relies on nonlinear functions competition. New ways understanding investigating species diversity follow these results.
