Long-term Eastern Diamondback Rattlesnake Monitoring

Since 2008, we have been monitoring a sea island eastern diamondback rattlesnake (C. adamanteus; EDB) population to examine questions about EDB ecology and conservation. Although project goals have changed over the years, the research uses radio telemetry and mark-recapture data to address management and conservation issues. Current research activities include:
1) Using adaptive management to develop and assess human-rattlesnake conflicts management policy
2)
EDB reproductive ecology

Modeling the Extirpation of Carolina Gopher Frogs in South Carolina

In light of Carolina Gopher Frog (Rana capito) population declines and the species’ review for federal protection under the Endangered Species Act, we initiated an acoustic monitoring program at historical gopher frog breeding locations in South Carolina. In collaboration with the South Carolina Department of Natural Resources and with support of the United States Fish and Wildlife Service, the goals of the current study are to use remotely sensed acoustic anuran call data and gopher frog absence from historical breeding sites to assess extirpation at a regional scale.

Long-term Amphibian and Reptile Monitoring in the South Carolina Coastal Plain

This project is being conducted in collaboration with the South Carolina Department of Natural Resources, who started monitoring rattlesnakes and corn snakes on state-owned properties in the South Carolina Coastal Plain in 1996. This study focuses on the imperiled longleaf pine ecosystem that once dominated the southeastern Coastal Plain. In 2010, the project was expanded to include anurans, salamanders, and all snake and turtle species.
This study has evolved into a long-term monitoring program that incorporates a natural experimental design to examine functional and structural aspects of ecological integrity. Currently, our long-term research is examining interactions between ecological restoration and species life history traits, with particular emphasis on species endemic to the longleaf pine ecosystem. This pioneering research was crucial for South Carolina's response to the petition to list eastern diamondback rattlesnakes (Crotalus adamanteus) for protection under the Endangered Species Act. This research has provided much-needed information about eastern diamondback rattlesnake ecology (habitat specificity, survival, age at maturation, and dispersal).

Graduate students in the Marshall University Herpetology and Applied Conservation Lab are strongly encouraged to participate in this research project. The lab makes numerous trips to the study site to collect long-term monitoring data. Students are encouraged to generate and conduct smaller studies that complement broader goals and have the potential to result in peer-reviewed publications (e.g., Fill et al. 2012).
