Drought survival is a threshold function of habitat size and population density in a fish metapopulation

RSA White, PA McHugh, AR McIntosh - Global Change Biology, 2016 - Wiley Online Library
Because smaller habitats dry more frequently and severely during droughts, habitat size is
likely a key driver of survival in populations during climate change and associated increased …
