Impacts of climate change on fish species and aquatic ecosystems in the Great Lakes and Prairie regions of Canada / Effects of climate change on fish species of the Great Lakes and Prairie regions of Canada Climate change risk assessment : streams in the Great Lakes Basin, Ontario Potential effects of climate change on fish habitat, primary and secondary productivity, and connectivity in freshwater ecosystems “This compilation report aims to provide a summary of available information on climate change effects on aquatic life in the Freshwater basins of Canada. An important outcome of this review is a summary of gaps of knowledge. The first chapter is a review of predicted climate induced changes on freshwater fish communities and food webs and details the effects of changes in biotic and abiotic processes on freshwater fish communities and food webs. The second chapter describes the impact that changes in climate are expected to have both directly and indirectly on a variety of fish species and their habitats. The third Chapter describes suitable thermal habitat for stream biota based on different climate variables to assess the potential impacts of climate change on the distribution of coldwater stream fish species in the Great Lakes Basin. The last chapter provides an overview of climate change impacts on water temperature, water chemistry, ice cover, water levels, and productivity. This report provides significant evidence that under a changing climate we can expect significant changes in the spatial extent and duration of preferred thermal habitat for ecologically and economically important fish across the Freshwater region. Warming temperatures expected with climate change will cause areas to approach water temperatures that are no longer thermally optimum for fish species. Species will need to migrate to find suitable habitats and productivity and survival success may decline for some species. Greater habitat overlap may intensify interguild competition and food web interactions. These changes in thermal habitat may intensify top down food web effects”--Abstract. gccst Climate change gccst Environmental impact gccst Freshwater fish gccst Aquatic ecosystems Abdel-Fattah, Sommer.
