Toni Lyn Morelli (she/her)
Adjunct Assistant Professor
USGS Research Ecologist
Toni Lyn is a research ecologist that has lived all over the world and now resides in beautiful Western Massachusetts. She is a proud mom of the passionate Darrow; read more about how being a mom has affected her science:
In her role as USGS Research Ecologist for the NE CSC, Toni Lyn uses species distribution modeling, occupancy modeling, geospatial analysis, and population and landscape genetics techniques, facilitated by translational ecology, to improve conservation in the face of global change.
Currently she is investigating how climate change is affecting species ranges in the northeastern United States; identifying climate change refugia across the world; using citizen science to track biodiversity change; using decision science to drive research questions and improve outcomes; and helping natural resource managers reduce the impacts of climate change and invasive species.
