One commonly cited benefit to animals that forage in groups is an increase in the probability
of detecting a predator, and a decrease in the time spent in predator detection. A …

A central controversy in ecology addresses the relative importance of competi-tion and
predation in determining the characteristics of organisms (eg behavior, life history) …

We propose a Survival Optimization System (SOS) to account for the strategies that humans
and other animals use to defend against recurring and novel threats. The SOS attempts to …

A technique for using patch giving up densities to investigate habitat preferences, predation
risk, and interspecific competitive relationships is theoretically analyzed and empirically …

To balance conflicting demands for food and safety from predation, feeding animals have
two useful tools. First, they can vary the amount of time they devote to harvesting patches …

Predatory threat can vary during a predator-prey interaction as an attack escalates or among
predators at different times. A Threat-sensitivity hypothesis is presented which predicts that …

Current methods for evaluating habitat selection from animal space‐use observations ignore
possible interactions between time allocation patterns relative to different resources, their …

The body mass (or fat reserves) maintained by a wintering bird can be viewed as a trade—
off between the risk of starvation and the risk of predation. This follows from the fact that fat …

Animals commonly choose among habitats that differ both in foraging return and mortality
hazard. However, no experimental study has attempted to predict the level of increase in …

We experimented on how illumination, habitat structure, and three different species of owls
affected the foraging behavior of Gerbillus allenbyi and G. pyramidum, two gerbil species …
