The Effect Of Mast Availability On Ambush Site Selection In Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Berlynna May Heres

Theses, Dissertations and Capstones

I examined ambush site selection in eastern diamondback rattlesnakes (Crotalus adamanteus). The eastern diamondback rattlesnake (EDB) is an imperiled, ambush predator endemic to southeastern pine savannas and woodlands of the United States. Eastern diamondbacks prey on small mammals that feed on hard and soft mast (e.g., nuts and fruits). In this study, I hypothesized that intra-seasonal shifts in masting vegetation would cause intra-season shifts in ambush site selection in EDBs as the result of a bottom-up trophic effect. I quantified EDB ambush site selection using radio telemetry data and vegetation analysis within a naturalized study site. When EDBs were encountered …
