“…Moreover, this effect is more pronounced in organically polluted systems as increasing temperature and pollution interact to reduce available dissolved oxygen (Moran et al, 2010;Verberk & Bilton, 2011). In this regard, there is a considerable need for research investigating the impact of these interactions on salmonid populations and other stream fauna if we are to identify adaption and mitigation measures to ensure their continued survival (Chen, Todd, Murphy, & Lomnicky, 2016).…”

This study evaluated the effects of riparian tree cover and channel morphology on the thermal regimes of 3 adjacent rivers in different years. Riparian tree cover was found to exert a strong modifying influence on stream temperature, with reduced mean maximum summer temperature at sites having greater tree cover. The effect of tree cover changed among years, such that greater cover was required to maintain a given water temperature regime in the warmer summer of 2013 than in 2014 or 2015. Water temperature was also related to mean depth in some years; shallower sites, typically associated with artificial channel widening, showed greater temperature extremes. These results suggest that the thermal resilience of modified streams can be improved by restoration of riparian tree cover and restored channel morphology. This finding is relevant to climate change proofing of temperate river channels, where cold‐water fauna are important elements of the biotic community.

“…The results also signal a direction for further fisheries research incorporating a broad range of interacting elements beyond water chemistry and temperature, but also eco‐hydromorphological condition, in identifying adaptation and mitigation measures in response to climate change. For example, minimum riparian buffer widths, refuge availability and minimum discharges are all important topics that fall under this umbrella (Chen, Todd, Murphy & Lomnicky, ; Fullerton et al., ). In particular, quantifying the effect of a warming climate in tandem with altered flow regimes on salmonid abundance in river systems is necessary (Wenger et al., ) for informing process‐based mitigation and restoration strategies (Pletterbauer, Melcher & Graf, ).…”

This study investigated interactions between eco‐hydromorphological state, riparian vegetation cover, water temperature and fish community composition in lowland rivers in Ireland. Physical habitat modification of study sites corresponded with degraded eco‐hydromorphological state (degree of ecological and physical modification) and reduced thermal buffering capacity (greater temperature fluctuation and increased frequency of extreme temperature events). This impact was reflected in the fish community, with a shift from a brown trout‐dominated (Salmo trutta L.) fish assemblage to predominance of the more thermally plastic minnow, Phoxinus phoxinus (L.), and stone loach, Barbatula barbatula (L.). Eco‐hydromorphological state may be a central factor affecting the ability of temperate rivers to resist temperature change in a warming climate and to maintain suitable conditions for salmonids and other cold‐water biota. Strategies aimed at climate change proofing of temperate rivers should focus on preserving or re‐establishing the eco‐hydromorphological processes that create habitat complexity and buffer stream temperature.

“…These include contamination of water by pharmaceuticals (Box 1) and microplastics (Box 2), and the threat increased urbanization poses to water chemistry and temperature (Box 3). Exacerbating these issues are the effects of climate change on water quality (Chen et al 2016). Differing approaches will be necessary to address these distinct threats (e.g., pretreatment for pharmaceuticals and microplastics versus land use planning and effective stormwater management for urbanization), and will provide opportunities to develop stronger collaboration between fisheries and water quality professionals.…”
