Neonicotinoids and Optimal Foraging Theory

open access: yesEnvironmental Advances, 2022
Determination of how neonicotinoid ingestion affects the foraging behaviour of flower-visiting animals, and using Optimal Foraging Theory to assess the nature and extent of consequent changes to foraging efficiency, provide a novel approach for ...

An application of upscaled optimal foraging theory using hidden Markov modelling: year-round behavioural variation in a large arctic herbivore [PDF]

open access: yesMovement Ecology, 2020
Background In highly seasonal environments, animals face critical decisions regarding time allocation, diet optimisation, and habitat use. In the Arctic, the short summers are crucial for replenishing body reserves, while low food availability and ...

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 ...

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.

Optimal foraging predicts the ecology but not the evolution of host specialization in bacteriophages. [PDF]

open access: yesPLoS ONE, 2008
We explore the ability of optimal foraging theory to explain the observation among marine bacteriophages that host range appears to be negatively correlated with host abundance in the local marine environment.

Insights for caribou/reindeer management using optimal foraging theory

open access: yesRangifer, 1991
Optimal foraging theory is useful to wildlife managers, because it helps explain the nutritional value of different habitats for wildlife species. Based upon nutritional value, the use of different habitats can be predicted, including how factors such as
