Genetic Structure of the Copperhead (Viperidae: Agkistrodon Contortrix Mokasen) at its Most Northern Distribution
… the molecular ecology of the Copperhead (<em>Agkistrodon contortrix</em>), other than to evaluate male reproduction in a laboratory setting and phylogenetic history. Thus, employing DNA-based molecular techniques to study the natural history of <em>A. contortrix</em> will broaden our knowledge …

Food Habits, Growth, Conversion Efficiency and Response to Prey Odors of the Copperhead, Agkistrodon Contortrix
Food habits, conversion efficiency, and tongue flick rate (TFR) during exposure to food odors were investigated during this study. Sixty-one adult copperheads were examined for prey remains and yielded 31 prey items of which 50% were small mammals. Captive neonates were observed to feed only on …

Evidence of Non-Strike Induced Chemosensory Searching by Eastern Copperheads (Agkistrodon Contortrix) During Cicada Predation
… active foraging by eastern copperheads, <italic>Agkistrodon contortrix</italic>, contradicts its description as an envenomation-reliant ambush predator. Evidence of active foraging through non-strike induced chemosensory searching (NSICS) was previously found in cottonmouths (<italic>A. …

Population Demographics And Active Foraging Behavior Of Copperheads (Agkistrodon Contortrix) At A Recreational Site In Eastern Kentucky
… site in Kentucky where copperhead snakes (Agkistrodon contortrix) are known to aggregate and forage. Capture-recapture data were used to 1) describe the demographic structure of the population and 2) construct models that quantify the probability of apparent survival (S) and recapture (p) …

Impacts of Driving Factors on Annual Cicada Emergence in Relation to the Seasonal Abundance of Eastern Copperheads (Agkistrodon contortrix)
… such predator is the Eastern Copperhead (<italic>Agkistrodon contortrix</italic>) that has been noted feeding on emerging cicadas throughout their range. In eastern Kentucky, observations of copperheads congregating to feed on cicadas has been documented in recreational areas. This creates an …

The effects of snake venoms as cytotoxins on selected prostate cancer cell lines
… snake venoms obtained from Naja pallida, Agkistrodon piscivorus conanti and Agkistrodon contortrix laticinctus were evaluated for cytotoxicity and selectivity in vitro against a panel of prostate cancer cell lines (DU145, PC3, LNCaP) and a non-malignant prostate epithelial cell line …

Individual capture history affects site use and defensive behavior of foraging eastern copperheads at a recreational site
… of site use of foraging of eastern copperheads (Agkistrodon contortrix) at Koomer Ridge Campground in the Daniel Boone National Forest, Kentucky. Since 2015 this site has been used for ongoing, annual mark-recapture studies of the foraging ecology of copperheads as they predate emerging annual …
