Predator Recognition Learning in Rainbow Darters (Etheostoma Caeruleum)
… could learn to associate cues from an unfamiliar predator with a known fright stimulus (darter alarm cues) through the process of classical conditioning. Darters in the experimental group (n=32) were trained using their alarm cues paired with cues from larval ringed salamanders (unfamiliar …

Predator Recognition and Avoidance in the San Marcos Salamander
Selection by predators is among the most important forces acting on prey populations. To persist with predators, prey must be able to recognize and respond to predatory threats. Despite the benefits of avoidance, there are time allocation tradeoffs with foraging and mating that make excessive …

Predator recognition and anti-predator behavior in juvenile Asian carp
… many prey fishes. Chemical, social, and similar predator cues may all inform an individual of a possible impending predatory threat. Bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) widespread invasive fishes, and can be vulnerable to predation during their first year. Because …

EARLY-LIFE DEVELOPMENT OF ANTIPREDATOR BEHAVIOUR OF JUVENILE NORTHERN CRAYFISH (FAXONIUS VIRILIS)
… cues, to assess predation risk and guide antipredator responses. Early exposure to risk-related cues can influence the development of antipredator strategies, including generalized responses to novelty (neophobia) and the ability to learn predator recognition through associative conditioning. …

Social learning and its effect on conservation efforts in the Barrens Topminnow: an evaluation of conditioning and social learning as a viable longterm solution to evolutionary traps
… are capable of socially learning conditioned predator recognition, and I hypothesized that BTMs are capable of social learning and that such learning might improve survival of BTMs. To explore the role of conditioning and subsequent learning in the conservation of BTMs, I conducted a series of …

Behavioral Responses By Cottonmouths (Agkistrodon Piscivorus) To Chemical And Visual Predator Cues
<p>Predator detection and assessment of predation risk have important survival consequences for animals. However, responses to predatory threats can vary with different stimuli. Chemical cues are important for predator recognition but visual cues may elicit defensive responses. Cottonmouths …

The Effects Of Acidic Conditions And Tannins On The Survival, Development, And Behavior Of Cope’s Gray Treefrog (Hyla Chrysoscelis)
… tannins, on the survival, development, and anti-predator behavior of Hyla chrysoscelis tadpoles. I conducted a field oviposition study to determine adult female site choice, and reared tadpoles in acidic and tannic conditions to investigate survival and antipredator behaviors. I found that female …
