Many prey species are faced with multiple predators that differ in the degree of danger posed. The threat-sensitive predator avoidance hypothesis predicts that prey should assess the degree of threat posed by different predators and match their behavior according to current levels of risk. To test this prediction, we compared the behavioral responses of nocturnal velvet geckos, Oedura lesueurii, to chemicals from 2 snakes that pose different threats: the dangerous broad-headed snake…

Antipredator behaviour of invasive geckos in response to chemical cues from snakes
Some evidence is found indicating Asian house geckos are threat-sensitive to some Australian predacious snakes, providing some support for the threat-sensitivity hypothesis.
Antipredatory reaction of the leopard gecko Eublepharis macularius to snake predators
It is concluded that the leopard gecko possesses an innate general antipredatory reaction to different species of snake predators, while a specific reaction to 2 particular sympatric species can be observed.
Chemical recognition in a snake–lizard predator–prey system
The ability of a generalist saurophagous snake, Philodryas chamissonis, to discriminate scents of two congeneric and sympatric lizard prey species, Liolaemus nitidus and L. chiliensis, was explored and results showed that the snake had a refined discrimination of lizard prey.
Generalization of predator recognition: velvet geckos display anti-predator behaviours in response to chemicals from non-dangerous elapid snakes
Generalised responses to predator chemicals may be common in prey species that co-occur with multiple, ecologically similar, dangerous predators (Current Zoology 56 (3): 337-342, 2010).
Wary invaders and clever natives: sympatric house geckos show disparate responses to predator scent
The invasive gecko showed generalized predator avoidance, and the lack of response by native geckos as threat sensitive is interpreted, suggesting that they may require additional cues beyond scent alone to judge the situation as threatening.
Testing the Threat‐Sensitive Hypothesis with Predator Familiarity and Dietary Specificity
The gradient of observed responses to different snake cues indicates that sirens may be evaluating predation potential of animals based on their foraging specificity and familiarity.
The Use of Chemical Cues by Granite Night Lizards (Xantusia henshawi) to Evaluate Potential Predation Risk
This study demonstrates that Granite Night Lizards can use chemical cues from their predators to assess predation risk, but further research is needed to assess whether these responses differ based on the diet of the predator.
Behavioural response of xerophilous land snail and slug species to chemical cues from ground-beetle predators: the role of ecological relevance
The response of the xerophilous land snail, Xeropicta derbentina, to the presence of chemical cues from several predacious ground beetles is examined, which is consistent with a species-specific perception of predation threat in terrestrial gastropods, which may be based on a combination of ecological and biological features in both species.
Effects of intraguild predators on nest-site selection by prey
This field experiment demonstrates that intraguild predators can directly influence the nest density of prey by altering maternal nest-site selection behavior, even when the predator and prey are active at different times of day and the eggs are not at risk of predation.


Chemical cues from both dangerous and nondangerous snakes elicit antipredator behaviours from a nocturnal lizard
Chemosensory Recognition and Behavioral Responses of Wall Lizards, Podarcis muralis, to Scents of Snakes that Pose Different Risks of Predation
Compared the tongue-flick rates and behavioral patterns of Wall Lizards in response to exposure to chemical signals of these four snake species that pose different risks of predation, it is suggested that other additional cues are probably needed to elicit an adequate, specific defensive response.
Experimental Evidence of an Age-Specific Shift in Chemical Detection of Predators in a Lizard
It was found that juvenile E. heatwolei avoided predator odors more strongly than adults, and the importance of predator ecology in the evolution of predator detection mechanisms, with chemical cues being more useful in detecting sedentary predators than active predators.
Chemical discrimination among predators by lizards: Responses of three skink species to the odours of high‐ and low‐threat varanid predators
Analysis of the responses of three species of skink to two species of predatory goanna found that prey are clearly able to avoid predators based on chemical cues, and can discriminate among similar predators that pose different levels of threat.
Intraguild predation, thermoregulation, and microhabitat selection by snakes
It is suggested that thermoregulatory considerations are sufficient to prompt juvenile (but not adult) broad-headed snakes to risk IG predation, emphasizing the importance of microhabitat quality and body size in mediating IG predator--prey interactions.
Sedentary snakes and gullible geckos: predator–prey coevolution in nocturnal rock-dwelling reptiles
These data support the notion that the 'ambush' predator benefits by remaining sedentary within a retreat-site for long periods, because it thereby minimizes the extent to which it spreads its scent over the rocks forming the crevice.
The scent of death: Chemosensory assessment of predation risk by prey animals
This paper provides an exhaustive review of the literature on the responses of prey to predator chemosensory cues, primarily in tabular form, and highlights the most important studies on predator activity level and diet.
Threat-sensitive predator avoidance in damselfish-trumpetfish interactions

Initial results indicate that damselfish threatened by predators respond in a graded manner that reflects the degree of threat posed by the predator, in accordance with the Threat-sensitivity hypothesis.
Responses of American toad tadpoles to predation cues: behavioural response thresholds, threat-sensitivity and acquired predation recognition
This study exposed American toad (Bufo americanus) tadpoles to varying concentrations of chemical alarm cues and conditioning them to recognize the predator by pairing the dragonfly odour with either the sub-th threshold concentration or the supra-threshold concentration of alarm cues.
