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 ...

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 ...

Promoting Quantitative Skills in Introductory Classes Using Optimal Foraging Theory and a Model-Assisted Activity [PDF]

open access: yesJournal of Microbiology & Biology Education, 2017
TMathematical models help students identify and understand underlying scientific patterns, while improving and reinforcing quantitative skills. However, they are often omitted from introductory undergraduate science classes.

The application of foraging theory to the information searching behaviour of general practitioners [PDF]

open access: yesBMC Family Practice, 2011
Background General Practitioners (GPs) employ strategies to identify and retrieve medical evidence for clinical decision making which take workload and time constraints into account.

Testing optimal foraging theory in a penguin-krill system. [PDF]

open access: yesProc Biol Sci, 2014
Food is heterogeneously distributed in nature, and understanding how animals search for and exploit food patches is a fundamental challenge in ecology. The classic marginal value theorem (MVT) formulates optimal patch residence time in response to patch quality.

Optimal foraging theory and niche-construction theory do not stand in opposition. [PDF]

open access: yesProc Natl Acad Sci U S A, 2015
In a recent paper, Zeder (1) outlines core archaeological questions in domestication research, highlighting the importance of defining the process, when it happened, and why it happened in various global contexts. Importantly, she emphasizes the utility of separating initial domestication from intensive agricultural practices, pointing out that often ...

Experience-based optimal foraging on planktonic prey in Baikal seals [PDF]

open access: yesMovement Ecology
Background 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.

Mechanism of Dietary Variation of Grazing Yaks on Tibetan Plateau: The Role of Seasonal Heterogeneity of Resources [PDF]

open access: yesEcology and Evolution
Diet 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]

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 ...

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
