Human activities and climate change threaten coldwater organisms in freshwater
ecosystems by causing rivers and streams to warm, increasing the intensity and frequency of …

Thermal refuges are thermally distinct riverscape features used by aquatic organisms during
unfavourable thermal events, facilitating resilience in marginal environments. However, the …

Summer water temperatures are rising in many river systems in North America, and this
warming trend is projected to intensify in the coming decades. Cold‐water fish may alleviate …

Cold groundwater discharge to streams and rivers can provide critical thermal refuge for
threatened salmonids and other aquatic species during warm summer periods. Climate …

Prevailing theory suggests that stream temperature warms asymptotically in a downstream
direction, beginning at the temperature of the source in the headwaters and levelling off …

Climate-change driven increases in water temperature pose challenges for aquatic
organisms. Predictions of impacts typically do not account for fine-grained spatiotemporal …

Water temperature governs the distribution and behaviour of fish. Riverine salmonids use
discrete cold water patches, termed thermal refuges, when stream temperature exceeds …

Stream temperature is a key habitat variable controlling all physical and biological river
processes. In light of the threat of climate change to fluvial environments, growing …

Temperature is a fundamental aspect of water quality in rivers, controlling the rate of many
ecological processes. By disrupting the flow of water, large reservoirs and dams can …

The forecast of warmer weather, and reduced precipitation and streamflow under climate
change makes freshwater biota particularly vulnerable to being exposed to temperature …
