Conservation Genetics of Threatened Pacific Northwest Salamanders
Completed
Amphibians may be disproportionately affected by habitat fragmentation due to their sensitivity to temperature, short dispersal ranges, and extreme site fidelity. These physical and habitat limitations may affect a population’s genetic structure and status. The USGS has used molecular genetic methods to assess population characteristics for a number of frogs and salamanders considered species of concern in the Pacific Northwest: the spotted frog, Oregon slender salamander, Larch Mountain salamander, southern torrent salamander, Cascade torrent salamander, Columbia torrent salamander, and Olympic torrent salamanders. This research provides critical information about these populations plus tests the utility of molecular techniques in resolving various aspects of amphibian evolution, population change, behavior, and conservation status.
