Crayfish have experienced extensive community reorganization as a result of global change, with some species becoming globally invasive while others have become rare or extinct. We combined historical and contemporary sampling data to determine temporal trends of crayfish assemblages of Wyoming, United States (1969–2020). The dataset includes previous statewide surveys and more narrow studies focusing on locations like Yellowstone National Park, individual native species, or newly discovered populations of invasive Faxonius rusticus. It also includes data from a 2020 statewide sampling effort of crayfish assemblages at 289 sites between April and November 2020.
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.
