Project Overview Climate change and human activities are threatening many sensitive aquatic species in prairie streams across the Great Plains region. Researchers supported by this North Central CASC project will combine and analyze data collected independently by Great Plains states to identify thresholds of environmental change that may lead to species loss and changes in aquatic communities. This information can guide managers in deciding whether to resist, accept, or direct change in these ecosystems to protect organisms and ecosystem services. Project Summary Prairie streams provide economic, recreational, and municipal services for human society and critical habitat for aquatic organisms including fish, crayfish,...

Objectives of this project are to examine historic and current spatial patterns and occurrence of native and non-native fishes relative to thermal regimes in the White River from about Meeker, Colorado to the confluence with the Green River in Utah; to model thermal resources in the White River and its tributaries to gain understanding of preferred thermal requirements for fish species; to determine zones of overlap for native and non-native fishes; and to provide land managers with information that will help protect fish communities in the White River.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
