MORE THAN COLD: TOWARD A COMPREHENSIVE IDENTIFICATION OF COLD-WATER REFUGES AND CLIMATE REFUGIA FOR AQUATIC LIFE
Cold water refuges (CWR) – areas of cold water in which thermally-stressed individuals may seek temporary shelter – are increasingly invoked as a potentially mitigating feature within warming river systems. CWR use is often assumed to confer benefits to fishes by providing temporary shelter from adverse conditions. But CWR use and thermoregulation is not without costs. Increased risk of predation, lost opportunity for foraging, and increased isolation within thermally-fragmented river systems may offset potential benefits. To provide a framework for assessing CWR, we illustrate a conceptual model of CWR costs/benefits that recognizes that CWR provisioning ability is influenced by the suitabilities, capacities and characteristics of individual refuges, as well as the spatial and temporal context of the surrounding matrix and the suite of potentially connected neighboring refuges. Networks of CWR and their context in relation to extensive areas of cold water serving as core areas can also be understood to function as important elements of larger-scale climate refugia for highly-migratory species like salmon. This framework is intended to be useful as state and federal regulatory agencies continue to incorporate concepts of CWR into water temperature standards and TMDLs.
