Abstract
Organisms must make choices to improve their survival, and often perform behaviors in response to stimuli in the environment. I examined behavioral responses under conditions of stress in a species of fully aquatic salamander, Western Lesser Sirens (Siren intermedia nettingi Goin 1942). First, I presented individuals with chemical cues from a variety of known prey items to determine a potential prey preference. Sirens did not exhibit a preference by prey type. I then exposed individuals to chemical cues from prey, predator, and insecticide sources and evaluated behavioral responses, while also administering a nonlethal physical injury to a subset of subjects prior to cue presentation. Sirens did not associate preferentially with any chemical cue type, although trends emerged in duration of performing certain behaviors. Finally, I considered the regeneration rate of siren tail tissue, and found that minor excisions from this region are effective short-term individual markings for mark-recapture studies.
