The importance of warm habitat to the growth regime of cold-water fishes

Nature Climate Change, Published online: 25 March 2021; doi:10.1038/s41558-021-00994-y

Modelling riverine fish growth across warm and cool sections of a river network, the authors demonstrate that habitats that are suboptimally warm in summer may actually provide the majority of growth potential. This highlights a risk in conservation strategies that devalue ephemerally warm habitats.
