Optimal foraging by a large ungulate in an extreme environment: Wild mountain reindeer select snow‐free feeding habitats in winter [PDF]
Ecology and Evolution, 2021 Optimal foraging models predict that individual animals will optimize net energy gain by intensifying forage activity and/or reducing forage energy cost. Then, the free distribution model predicts an animal's distribution in a patchy landscape will match

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.

Game-theoretic methods for functional response and optimal foraging behavior. [PDF]
PLoS ONE, 2014 We develop a decision tree based game-theoretical approach for constructing functional responses in multi-prey/multi-patch environments and for finding the corresponding optimal foraging strategies.

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

Foraging as an evidence accumulation process.
PLoS Computational Biology, 2019 The patch-leaving problem is a canonical foraging task, in which a forager must decide to leave a current resource in search for another. Theoretical work has derived optimal strategies for when to leave a patch, and experiments have tested for ...

Combining radio-telemetry and radar measurements to test optimal foraging in an aerial insectivore bird [PDF]
eLifeOptimal foraging theory posits that foragers adjust their movements based on prey abundance to optimize food intake. While extensively studied in terrestrial and marine environments, aerial foraging has remained relatively unexplored due to technological

A reward self-bias leads to more optimal foraging for ourselves than others [PDF]
Scientific ReportsPeople are self-biased for rewards. We place a higher value on rewards if we receive them than if other people do. However, existing work has ignored one of the most powerful theorems from behavioural ecology of how animals seek resources in everyday ...

Current Biology, 2022 Before visiting your local supermarket, do you write your food shopping list in the order you expect to encounter the items as you walk around, aisle by aisle? This way, you minimise your travel distance, saving time and effort. Many other animals do the same.

A Hypothetical Modelling and Experimental Design for Measuring Foraging Strategies of Animals
Journal of Intelligence, 2022 Based on animal long-term and short-term memory radial foraging techniques (or LMRFT and SMRFT), we devise a modelling approach that could capture the foraging behaviours of animals.

Neonicotinoids and Optimal Foraging Theory
Environmental 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 ...
