Tiger Salamander

Eastern Tiger Salamander

Our research on tiger salamanders is focused on monitoring their population dynamics, identifying how habitat quality in breeding ponds and upland non-breeding habitats affects their population demography, and how landscape fragmentation affects their dispersal.  Tiger salamanders are widespread across the US, but are becoming increasingly rare in North Carolina and the southeast.  They are considered a state threatened species, as loss of ephemeral wetlands and undisturbed non-breeding habitat has caused their populations to decline.  Among other approaches, we are using photographic identification to monitor natural populations in a handful of breeding ponds [more info....].  We are also conducting telemetry studies to track adults as they return to non-breeding habitat, and we are conducting experiments with metamorphs to test how habitat boundaries affect their dispersal.

In addition to working with tiger salamanders, Will Fields is conducting landscape-level population studies on the endangered flatwoods salamander.

Our research on St. Francis satyr is funded by DoD, Department of the Army, Endangered Species Branch at Ft. Bragg and the Strategic Environmental Research and Development Program
