“…Predator recognition is typically tested by bioassays that determine whether responses of salamanders to predator kairomones are consistent with antipredator behavior. For example, stimuli from predatory garter snakes (Thamnophis sirtalis) and ringneck snakes (Diadophis punctatus) have elicited avoidance responses [21,22] and reduced foraging activity [23][24][25]; the latter behavior is consistent with both increased vigilance and decreased visibility to visual predators. Physiologically, antipredator responses can be manifested as increased respiration (e.g., [26]), apparently as a component of the frightor-flight response.…”

When new predators invade a habitat, either through range extensions or introductions, prey may be at a high risk because they do not recognize the predators as dangerous. The nine-banded armadillo (Dasypus novemcinctus) has recently expanded its range in North America. Armadillos forage by searching soil and leaf litter, consuming invertebrates and small vertebrates, including salamanders. We tested whether Ozark zigzag salamanders (Plethodon angusticlavius) from a population coexisting with armadillos for about 30 years exhibit antipredator behavior in the presence of armadillo chemical cues and whether they can discriminate between stimuli from armadillos and a nonpredatory sympatric mammal (white-tailed deer,Odocoileus virginianus). Salamanders appeared to recognize substrate cues from armadillos as a threat because they increased escape behaviors and oxygen consumption. When exposed to airborne cues from armadillos, salamanders also exhibited an antipredator response by spending more time in an inconspicuous posture. Additionally, individually consistent behaviors across treatments for some response variables suggest the potential for a behavioral syndrome in this species.

“…In seven years of studies, we have documented a highly predictable avoidance response in the red-backed salamander, Plethodon cinereus, to body rinses from garter snakes, Thamnophis sirtalis, that have been feeding on P. cinereus (standard TSpc stimulus; Madison et al, 1999a,b;McDarby et al, 1999;Maerz et al, 2001;Sullivan et al, 2002Sullivan et al, , 2003. While we always get avoidance of TSpc, no such avoidance occurs in response to body rinses from garter snakes feeding on earthworms.…”
