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

BMC 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.

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

Frontiers 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 ...

Polar bears are inefficient predators of seabird eggs

Royal Society Open Science, 2021
Climate-mediated sea-ice loss is disrupting the foraging ecology of polar bears (Ursus maritimus) across much of their range. As a result, there have been increased reports of polar bears foraging on seabird eggs across parts of their range.

Effects of Personality Traits on the Food-Scratching Behaviour and Food Intake of Japanese Quail (Coturnix japonica)

Animals, 2021
Overall foraging success and ultimate fitness of an individual animal is highly dependent on their food-searching strategies, which are the focus of foraging theory.

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

Ecology 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 ...

Gazing at Social Interactions Between Foraging and Decision Theory

Frontiers in Neurorobotics, 2021
Finding the underlying principles of social attention in humans seems to be essential for the design of the interaction between natural and artificial agents.

Prey detection by a stepwise visual template matching mechanism

Royal Society Open Science
Predators can improve prey capture using a search image, and recent prey provide a visual template with which subsequent prey are compared. Considering trout feeding responses to mayfly prey of different sizes and phenological availability across years ...

Foraging theory predicts predator–prey energy fluxes [PDF]

Journal of Animal Ecology, 2008
1. In natural communities, populations are linked by feeding interactions that make up complex food webs. The stability of these complex networks is critically dependent on the distribution of energy fluxes across these feeding links. 2. In laboratory experiments with predatory beetles and spiders, we studied the allometric scaling (body-mass ...

Factors Modulating the Occurrence of the Selective-Value Effect in Tufted Capuchin Monkeys (Sapajus spp.)

Animals
During foraging decisions, animals often make irrational choices. The selective-value effect refers to the lack of preference for an option consisting of one highly preferred item plus one less preferred item compared to a single highly preferred item. A
