Behavioral and Metabolic Responses of Juvenile Spotted Salamanders (Ambystoma Maculatum) to Alarm Cues from Damaged Skin and Predator Diet
… of predation risk and perform appropriate antipredator behaviors when predation risk is high. I investigated the ability of lab-reared juvenile spotted salamanders, Ambystoma maculatum, to assess predation risk via chemical alarm cues and substrate markings from predators fed different diets. …

Biogeographic Patterns, Predator Identity, and Chemical Signals Influence the Occurrence and Magnitude of Non-lethal Predator Effects
Predators can have large effects on prey populations and on the structure and function of communities. In addition to direct consumption of prey, predators often cause prey to alter their foraging behavior, habitat selection, and morphology. These non-lethal effects of predators can propagate to …

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 …

Predation, turbidity, and other factors influencing juvenile Salmonid survival in the lower Snake River
… 32% (channel catfish), and 0% (walleye) of the predator diet. The ability of smallmouth bass to consume juvenile salmonid prey was investigated in vitro, using four turbidity levels (0, 0.5, 5 and 10 NTUs), and five prey densities (1,2,4,8,16 prey items). In trials with 16 prey items, predation …
