Identification of Sex and Parasitism via Chemical Cues by the Ozark Zigzag Salamander
… mode of information transfer among woodland salamanders of the genus Plethodon. These cues have been shown to convey a wide variety of information, and are used to establish territorial boundaries. Responses to chemical cues can include changes in both behavior and energy consumption. The …

Response of the Ozark Zigzag Salamander (Plethodon Angusticlavius) to High and Low Level Threats
… This study examined the foraging tactics of the Ozark zigzag salamander (Plethodon angusticlavius) under low and high levels of threat. I predicted that the salamander would specialize on the most profitable prey type under low levels of threat but would forage randomly under high threat. …

A Role For Parasites in the Behavior of the Ozark Zigzag Salamander (Plethodon Angusticlavius)
… host behavior. I studied the behavior of the Ozark zigzag salamander (Plethodon angusticlavius), that was naturally infected with the larval stage of an ectoparasitic mite (Hannemania eltoni) to determine if parasitism was associated with altered behavioral patterns. Experiments were designed …

The Influence Of Predation Risk On The Foraging And Territorial Behavior Of The Ozark Zigzag Salamander (Plethodon Angusticalvius)
… the potential for such trade-offs in the Ozark zigzag salamander, Plethodon angusticlavius. I performed a series of laboratory experiments to determine whether increased predation risk decreased foraging behavior and territorial defense. Foraging success of salamanders declined in the …

Effects of Prior Exposure to Predatory Chemical Cues on Territorial and Foraging Behaviors of the Ozark Zigzag Salamander, Plethodon Angusticlavius
… animals. Previous experiments have shown that Ozark zigzag salamanders (Plethodon angusticlavius) make behavioral changes when in direct contact with predatory chemical cues. I predicted that prior exposure to a predator cue would also affect the subsequent behavior of these salamanders. I …
