Toni Lyn Morelli

Research Ecologist, U.S. Geological Survey

Research Interests

After her Ph.D., Toni Lyn Morelli obtained a National Science Foundation Bioinformatics Postdoctoral Fellowship, collaborating with Steve Beissinger and Craig Moritz on an extension of the Grinnell Resurvey Project; she continues these collaborations examining climate refugia under funding she obtained from the California Landscape Conservation Cooperative. She has also worked for the U.S. Forest Service, both as a research ecologist at the Pacific Southwest Research Station and as the Technical Advisor to the Democratic Republic of Congo.

In her role as USGS Research Ecologist for the NE CSC, Toni Lyn uses geospatial analysis, species distribution modeling, occupancy modeling, and population and landscape genetics techniques to facilitate natural resource management and habitat and species conservation in the face of climate and land use change.  Currently she is investigating how climate change is affecting boreal communities in the northeastern United States.
