For fish and wildlife that are sensitive to changing temperatures, their ranges will shift or contract. I am using future projections for Montana and northern Wyoming streams to determine where temperatures will be suitable for aquatic species to survive. These areas are known as …
To properly conserve sensitive species and help determine where adaptation techniques will be most effective, this project will result in an interactive web app that shows where likely refugia will be located.
While the initial release of the refugia app will only account for temperature changes, the Rangeland Fisheries Refugia Project will provide the data needed to update the app to include drought projections and above-barrier translocation opportunities.
Fish Temperature Tolerances & Distributions
To determine temperature refugia for native fishes in the study area (see map), I am using data from multiple sources to determine 1) species distributions and 2) water temperatures required by those species.
Future updates will also include larger areas of Wyoming.
Predicting Future Temperatures for Prairie Streams
Torrent and Cedar Sculpin eDNA & Temperature Tolerance
An additional aspect of this project includes working with Mike Young of the National Genomics Center for Fish & Wildlife Conservation to develop eDNA tests to help determine distributions of Torrent Sculpin (Uranidea rhotheus) and Cedar Sculpin (Uranidea schitsuumsh).
