Honest Signaling in Aggressive Contests Between Ozark Zigzag Salamanders (Plethodon Angusticlavius)
… between pairs of Ozark zigzag salamanders (Plethodon angusticlavius), individuals that performed bites spent more time exhibiting ATR prior to biting than individuals that did not bite. In addition, I examined whether ATR is an energetically costly behavior. In trials where the diet of the …

Response of the Ozark Zigzag Salamander (Plethodon Angusticlavius) to High and Low Level Threats
… 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. Salamanders in the blank …

A Role For Parasites in the Behavior of the Ozark Zigzag Salamander (Plethodon Angusticlavius)
… 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 to answer three specific …

Influence of Physical Stress, Sex, and Body Size on Metabolic Rates of Ozark Zigzag Salamanders, Plethodon Angusticlavius
Ozark zigzag salamanders (Plethodon angusticlavius) are exposed to a variety of stressors, each eliciting a combination of behavioral and physiological responses. One response is an increase in oxygen consumption rate. Individuals were physically stressed to simulate a predatory attack, and oxygen …

Effects of Prior Exposure to Predatory Chemical Cues on Territorial and Foraging Behaviors of the Ozark Zigzag Salamander, Plethodon Angusticlavius
… 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 collected chemical cues from …

The Influence Of Predation Risk On The Foraging And Territorial Behavior Of The Ozark Zigzag Salamander (Plethodon Angusticalvius)
… 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 presence of both substrate …

Identification of Sex and Parasitism via Chemical Cues by the Ozark Zigzag Salamander
… 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 ability of Ozark zigzag …
