The Nations Fish Habitat in a Changing Climate Part 2

The effects of climate change on fish habitat will be scale-and system-dependent. Our work demonstrates how climate change affects fish habitat nationwide, and stream flow, water temperature, and coldwater lakes in the Upper Midwest. Projected changes in fish habitat varied across ecoregions nationally. The future regional climate will likely alter hydrologic and thermal regimes suitable to the fish species in that region. The results show that the scale at which we assess climate change impacts may influence decisions made, and that the different attributes of lakes and streams require different approaches to determine climate and land use change effects on fish habitat.
