Abstract Climate change-induced warming effects are already evident in river ecosystems, and projected increases temperature will continue to amplify stress on fish communities. In addition, many rivers globally impacted by dams, which have negative fishes altering flow, blocking passage, changing sediment composition. However, some systems, dams present an opportunity manage through regulated releases of cooler water. For example, there is a government mandate for Kenney dam operators the...
Abstract Heatwaves are increasing in frequency and severity, posing a significant threat to organisms globally. In aquatic environments heatwaves often associated with low environmental oxygen, which is deadly combination for fish. However, surprisingly little known about the capacity of fishes withstand these interacting stressors. This issue particularly critical species extreme conservation concern such as sturgeon. We assessed tolerance juvenile white sturgeon from an endangered...
Cross-protection occurs when exposure to one stressor confers heightened tolerance against a different stressor. Alternatively, could result in reduced other stressors. Although cross-protection has been documented wide range of taxa at juvenile and adult life stages, whether early developmental or stressors later through plasticity remains largely unexplored. In this study, we examined altered temperature during embryonic development results upper thermal hypoxia using small topminnow,...
Anthropogenic climate change threatens freshwater biodiversity and poses a challenge for fisheries management, as fish will increasingly be exposed to episodes of high temperature low oxygen (hypoxia). Here, we examine the extent variation in tolerance acute exposure these stressors within among five strains rainbow trout (Oncorhynchus mykiss) currently being used or under consideration use stocking programmes British Columbia, Canada. We incipient lethal saturation (ILOS) an index hypoxia...
