An Experimental Test of Central Place Foraging Theory in a Cooperatively Breeding Bird [PDF]

open access: yesEcology and Evolution
Central place foraging, whereby individuals are constrained in their foraging by their need to return to a central place, is common in nesting birds. A key prediction of the central place foraging theory models developed by Orians and Pearson is that as ...

Eating smart: Free-ranging dogs follow an optimal foraging strategy while scavenging in groups

open access: yesFrontiers in Ecology and Evolution, 2023
Foraging and acquiring of food is a delicate balance between managing the costs (both energy and social) and individual preferences. Previous research on solitarily foraging free-ranging dogs showed that they prioritise the nutritionally highest valued ...

The glass is half-full: overestimating the quality of a novel environment is advantageous. [PDF]

open access: yesPLoS ONE, 2012
According to optimal foraging theory, foraging decisions are based on the forager's current estimate of the quality of its environment. However, in a novel environment, a forager does not possess information regarding the quality of the environment, and ...

Optimal foraging and the information theory of gambling [PDF]

open access: yesJournal of The Royal Society Interface, 2018
At a macroscopic level, part of the ant colony life cycle is simple: a colony collects resources; these resources are converted into more ants, and these ants in turn collect more resources. Because more ants collect more resources, this is a multiplicative process, and the expected logarithm of the amount of resources determines how successful the ...

Prey‐driven behavioral habitat use in a low‐energy ambush predator

open access: yesEcology and Evolution, 2021
Food acquisition is an important modulator of animal behavior and habitat selection that can affect fitness. Optimal foraging theory predicts that predators should select habitat patches to maximize their foraging success and net energy gain, likely ...

The effects of a competitor on the foraging behaviour of the shore crab Carcinus maenas. [PDF]

open access: yes, 2014
Optimal Diet Theory suggests that individuals make foraging decisions that maximise net energy intake. Many studies provide qualitative support for this, but factors such as digestive constraints, learning, predation-risk and competition can influence ...

Prey-switching does not protect a generalist turtle from bioenergetic consequences when its preferred food is scarce

open access: yesBMC Ecology, 2020
Background Optimal foraging theory explains how animals make foraging decisions based on the availability, nutritional content, and handling times of different food types.

Learned valuation during forage decision-making in cuttlefish [PDF]

open access: yesRoyal Society Open Science, 2020
Decision-making, when humans and other animals choose between two options, is not always based on the absolute values of the options but can also depend on their relative values.

Sophisticated collective foraging with minimalist agents: a swarm robotics test [PDF]

open access: yes, 2020
How groups of cooperative foragers can achieve efficient and robust collective foraging is of interest both to biologists studying social insects and engineers designing swarm robotics systems. Of particular interest are distance-quality trade-offs and
