Mortality Risk Associated With Urban Land Use For Adult Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Mya Wiles Jan 2022

Mortality Risk Associated With Urban Land Use For Adult Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Mya Wiles

Theses, Dissertations and Capstones

Snakes have been a traditionally under-represented organism in urban ecology, but they face similar, if not greater challenges in the face of growing urban sprawl. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDBs) are under consideration for listing under the Endangered Species Act due to population declines resulting from historical human persecution and habitat loss. This study used radio-telemetry data from a long-term monitoring project of adult EDBs on a developed sea island in South Carolina, USA. I reclassified a National Land Cover Dataset to reflect relative mortality risk for snakes attempting to move through the landscape. High-risk cover types …


The Effectiveness Of Long-Distance Translocation Of Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Allison Grace Kelley Jan 2020

The Effectiveness Of Long-Distance Translocation Of Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Allison Grace Kelley

Theses, Dissertations and Capstones

Translocations have the potential to aim conservation efforts as well as to reduce mortality caused by human activities. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDB) have a limited ability to adapt to habitat loss and fragmentation due to the species’ slow life history and minimal dispersal ability. Because they are a venomous species, they are viewed as nuisance animals and are often killed on sight. We translocated a cohort of EDBs to investigate the potential of using translocations as a conservation and mitigation tool for this species. In July 2018, we translocated twelve adult eastern diamondback rattlesnakes from Parris …


Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Ambush Site Selection In Coastal Saltwater Marshes, Emily Rebecca Mausteller Jan 2020

Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Ambush Site Selection In Coastal Saltwater Marshes, Emily Rebecca Mausteller

Theses, Dissertations and Capstones

The eastern diamondback rattlesnake (Crotalus adamanteus; EDB) is a species of conservation concern associated with the imperiled longleaf pine-grassland ecosystem. The longleaf pine ecosystem is characterized by an open canopy and rich ground cover. Researchers have speculated that the vegetation structure of salt marshes may serve as a surrogate habitat for longleaf pine savannas. Although these marshes have little topography, they provide a heterogeneous landscape with patches of mud flats, sandy hard marsh along upper tidal areas, and salt marsh hummocks throughout. I used radio telemetry to monitor free-ranging EDBs on a South Carolina sea island. The goal of my …
