The effects of climate change on freshwater fishes and their habitats will likely not be consistent among species or habitats so region or species-specific effects of climate change may help managers focus conservation efforts.

Summary
This webinar is Part 1 in a set of two presentations. Part 2 was held on Thursday, May 9, 2013.
The effects of climate change on freshwater fishes and their habitats will likely not be consistent among species or habitats so region or species-specific effects of climate change may help managers focus conservation efforts. The first webinar (of two) for this nationwide project will show how climate change affects fish distributions in the desert southwest, brook trout distributions in the eastern U.S., and growth and consumption of smallmouth bass in the Midwest U.S. In the desert southwest, we developed a framework based on the predicted distribution of native species to serve as a surrogate measure of change in stream habitat condition from changes in climate and land use. Native species showed a general increase in distribution by 2085. These were primarily warm-water species. Of the two cold-water natives, we had enough records to model the distribution of the Apache trout which showed a 25% decline in distribution. In the Midwest, bioenergetics simulations showed that a 1°C stream temperature increase will increase smallmouth bass growth in the Midwest by 7% and consumption by 27%. For eastern brook trout increasing stream temperatures and urban land use change are predicted to result in 30 to 40% reductions in suitable stream habitat. These results show that climate change may affect fishes at the distributional and population levels, and may vary by species and region.
