Jay Diffendorfer

I'm an applied ecologist working at the Geosciences and Environmental Change Science Center.

Trained as an ecologist, I originally worked on spatial ecology and conservation biology, including a USGS-funded post doc at University of Miami modelling reptile and amphibian responses to possible restoration scenarios in the Everglades.  I then worked as an assistant and full professor at San Diego State University, studying relationships between urbanization, fire, and invasive species on a native flora and fauna in southern California. This field-oriented research involved radiotelemetry, capture-recapture, and vegetation studies.  I left San Diego State University and spent 4 years at the Illinois Natural History Survey where my research began to expand into disease ecology and agro-ecosystems.  Since arriving at USGS in 2008, I have continued to expand my research focus and currently work on science related to the energy-environment nexus, ecosystem services, and applied ecology.
