The northern pike (Esox lucius) is a selective and important predator in lake ecosystems.
Prey size in pike is limited by pike gape size, which is a linear function of pike body length …

Ants are central-place foragers: they always return to the nest, and this requires the ability to
remember relationships between features of the environment, or an individual's path through …

Ants are the most widely distributed and most numerically abundant group of social insects.
First, they were ground-or litter-dwelling predators or scavengers, and certain taxa evolved …

In social insects, the decision to exploit a food source is made both at the individual (eg, a
worker collecting a food item) and colony level (eg, several workers communicating the …

Omnipresent in virtually all terrestrial ecosystems and of undisputed ecological and
economical importance, the study of social insects is an area that continues to attract a vast …

Understanding the effects of cooperative hunting among the predators is an important topic
in ecology. We explore a prey–predator model with cooperative hunting among predators …

Any organism faces sensory and cognitive limitations which may result in maladaptive
decisions. Such limitations are prominent in the context of groups where the relevant …

Crematogaster sp. is a dominant arboreal ant species that captures and retrieves very large
prey. Hunting workers forage collectively thanks to short-range recruitment. They detect prey …

Recruitment helps insect societies by bringing individuals to places where work needs to be
done, but it also imposes energetic and opportunity costs. The net effect depends both on …

Cooperation in foraging through information sharing is widespread in social insects and has
been much studied. In contrast, cooperative transport of food items by groups of workers is …
