Karen Thorne

Biography

Dr. Karen Thorne is a Principle Investigator with the USGS Western Ecological Research Center, where her research focus is in climate change impacts to ecosystems. In particular, her work has included assessing sea-level rise and storms impacts to nearshore ecosystems, wetland ecology and wildife. She received her Ph.D. and MS from the University of California, Davis.

Dr. Thorne's interests lie in conservation issues surrounding climate-related research that assess changes to ecosystems and wildlife.  Her current focus is assessing how sea-level rise and storms impact salt marsh ecosystems and local wildlife populations. In particular, Dr. Thorne is interested in how wildlife respond to high water events and how this relates to predation and breeding success.  Her research is based on field data collection methods that can be developed into climate change impact models using ArcGIS and other remote sensing tools.
