Resource bottlenecks – periods of severe restriction in resource availability – triggered by increased climate variability represent important and little‐understood mechanisms through which climate change will affect biodiversity. In this review, we aim to synthesize the key global change processes that exacerbate the severity of bottlenecks in resource availability on animal populations, and outline how adaptation responses can help buffer the impacts.

Global.

We collate examples from the literature of population‐level impacts of resource bottlenecks induced by extreme weather and climate events to explore the types of population impacts that have most frequently been recorded, and the type of extreme events associated with them. We then develop a conceptual framework that captures the factors contributing to species’ vulnerability to climate‐induced spatial and temporal resource …
