Our Research
At VHREC, our research advances the scientific understanding of venomous reptiles and their ecosystems to support conservation, public safety, and education. We combine rigorous fieldwork, data analysis, and collaborative expertise to fill critical knowledge gaps and inform evidence-based management strategies. By integrating ecological insights with public outreach, our research empowers communities to coexist safely with venomous species while promoting the preservation of biodiversity.
Distribution and Environmental Correlates of the Genus Atheris Across Sub-Saharan Africa
Status: On-going
This project compiles and standardizes a comprehensive dataset of Atheris observations from iNaturalist, spanning the full natural range of the genus across Sub-Saharan Africa. Each occurrence is annotated with environmental and geographic variables, including elevation, canopy cover, forest coverage, biome classification, and climate zones. Using this dataset, our team is conducting species distribution and ecological niche modeling to identify optimal and predicted habitats for each species. Preliminary results reveal clear patterns of habitat specialization, such as high-canopy montane forests for certain species, and provide insights into areas where these vipers may occur but remain unobserved. The work informs conservation planning, venom ecology research, and field survey prioritization, while maintaining a reproducible workflow that balances scientific transparency with species protection.
Distribution Mapping of Venomous Snake Species in Eastern Tennessee
Status: Pending Permitting
Venomous snakes in Eastern Tennessee remain under-surveyed, limiting conservation planning, public safety interventions, and biomedical research. This project employs a multi-faceted field survey approach—including Visual Encounter Surveys (VES), roadkill collection, and limited temporary capture—to create a high-resolution geospatial dataset detailing venomous snake distributions, habitat use, and seasonal activity patterns. Collected genetic and parasitic data will provide ecological context and support long-term population monitoring.
Field Validation of Visible Implant Elastomer (VIE) Marking for Individual Identification and Population Monitoring of Non-Venomous Snakes
Status: Pending Permitting
This project evaluates the effectiveness of Visible Implant Elastomer (VIE) marking for reliable, non-invasive identification of free-ranging snakes. Conducted at Forks of the River Wildlife Management Area, the study combines field-based mark–recapture methods with pathogen monitoring, including skin and cloacal swabs for Ophidiomyces ophidiicola and other co-occurring pathogens. The research will assess VIE retention, detectability under natural and UV light, and provide standardized protocols for population monitoring and disease surveillance. Findings will inform wildlife management strategies, enhance ecological understanding, and support public safety and conservation efforts in urban-edge and conservation-relevant habitats.
