Experience-based optimal foraging on planktonic prey in Baikal seals [PDF]
Movement EcologyBackground Understanding how predatory animals efficiently locate prey with limited knowledge of its location is challenging. Optimal foraging theory suggests that animals improve their food intake through experience-based adjustments of search patterns.

Nest material preferences in wild hazel dormice Muscardinus avellanarius: testing predictions from optimal foraging theory. [PDF]
Behav Ecol, 2023 Obtaining nesting material presents an optimal foraging problem, collection of materials incurs a cost in terms of risk of predation and energy spent and individuals must balance these costs with the benefits of using that material in the nest. The hazel

Mechanism of Dietary Variation of Grazing Yaks on Tibetan Plateau: The Role of Seasonal Heterogeneity of Resources [PDF]
Ecology and EvolutionDiet composition is a crucial yet understudied, dimension of animal ecology, with seasonal dietary shifts being a key factor in the population dynamics of large herbivores.

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

Optimal Foraging: A Selective Review of Theory and Tests [PDF]
The Quarterly Review of Biology, 1977 Beginning with Emlen (1966) and MacArthur and Pianka (1966) and extending through the last ten years, several authors have sought to predict the foraging behavior of animals by means of mathematical models. These models are very similar,in that they all assume that the fitness of a foraging animal is a function of the efficiency of foraging measured in

Optimal Foraging Theory and the Psychology of Learning [PDF]
American Zoologist, 1983 The development of optimization theory has made important contributions to the study of animal behavior. But the optimization approach needs to be integrated with other methods of ethology and psychology. For example, the ability to learn is an important component of efficient foraging behavior in many species, and the psychology of animal learning ...

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