Current Research

My research focuses primarily on basic amphibian ecology and the impacts of forest management practices on amphibian communities. The long-range goals of my research are:
  • To determine the impacts of various forest management practices (including fragmentation) on amphibians
  • To determine likely consequences of climatic changes on amphibians
  • To develop guidelines for managing southern forest ecosystems to ensure healthy populations of amphibians
  • To develop and evaluate alternative monitoring protocols for amphibians
  • To develop and validate predictive habitat relationship models for amphibians.

Research Highlights

Even Small Roads Can Have a Big Impact (2016)
SRS-2016-180 Roads may be the single biggest driver of amphibian and reptile population declines and habitat loss in Neotropical rainforests.

Invasive Chinese Tallow Reduces Hatching of Frog Eggs (2012)
SRS-2012-07 Decomposing leaf litter reduces hatching of southern leopard frog eggs by lowering the pH and concentration of dissolved oxygen in the water

It’s the City Life for Me! Spring Peepers in Urban Areas have Lower Rates of Fungal Infection (2015)
SRS-2015-237 The spring peeper (Pseudacris crucifer) is a small frog widespread throughout the eastern U.S. and Canada. A Forest Service study reports that spring peepers in urban areas had significantly lower rates of a fungal infection than peepers from forested sites.
