Assessing the climate change vulnerability of freshwater fishes in Newfoundland and Labrador
Freshwater fish populations are rapidly declining globally due to the impacts of rapid climate change and existing non-climatic anthropogenic stressors. In response to these threats, freshwater fishes are responding by shifting their distribution range, altering the timing of migration and spawning...
