Response To Conspecific Alarm Cues By Spotted Salamander (Ambystoma Maculatum) Larvae, Katlyn M. Gardner
MSU Graduate Theses
Detection of predators early in a predation sequence may allow prey to increase their probability of survival by taking evasive action. For aquatic species in ephemeral ponds visibility is often limited, so predation risk assessment via chemical cues can be useful. Most mole salamanders of the genus Ambystoma breed in vernal ponds, and larvae suffer high mortality rates due in part to high levels of predation. I tested whether larvae can assess predation risk by detecting chemicals (alarm cues) released from the skin of damaged conspecifics, and, if so, what factors influence the response to this alarm cue. Field-caught spotted …
