摘要:
combine mass-based diet data with gastric evacuation times to estimate prey mass consumed per predator. An alternative approach is to estimate rates of prey

摘要:
Research on large predator-prey interactions are often limited to the predators’ primary prey, with the potential for prey switching in systems

摘要:
1. Prey distribution acts at multiple spatial scales to influence foraging success by predators. The overall distribution of prey may shape

摘要:
Predator dietary studies often assume that diet is reflective of the diversity and relative abundance of their prey. This interpretation ignores

摘要:
Large-scale ungulate migrations result in changes in prey availability for top predators and, as a consequence, can alter predator behavior
Data from: Safety cues can give prey more valuable information than danger cues

Behavior: antipredator;Modeling: predator\/prey;optimality theory;Modeling: individual based;Ecology: behavioral
摘要:
The ability of prey to assess predation risk is fundamental to their success. It is routinely assumed predator cues do not vary in reliability ac
