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 reduction in individual vigilance with an increase in group size is one of the most
frequently reported relationships in the study of animal behaviour. It has been argued that …

The bluegill sunfish (Lepomis macrochirus) undergoes several habitat shifts between the
littoral and pelagic zones of small lakes during its life history. After hatching in the littoral …

Avian fat storage is associated with both benefits and costs. Although the benefits of
maintaining higher energetic reserves have long been considered, the associated costs …

Although there is ample evidence for the generality of foraging and predation trade-offs in
aquatic systems, its application to terrestrial systems is less comprehensive. In this review …

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 …

Predation is considered one of the most important selective pressures on free-ranging
animals. Our understanding of it derives mainly from studies of individual vigilance (visual …

Many animals must often respond to environmental patterns that simulatneously influence
both foraging efficiency and predation risk. We noted that grey squirrels (Sciurus …

Grouping has been widely accepted as a mechanism for protection from predation. Just as
has been apparent with predation, there is now ample evidence that parasites (biting flies …

Growing evidence suggests that an understanding of avian anti-predatory escape tactics is
important in understanding the way in which predators influence avian ecological systems …
