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

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

Nest material preferences in wild hazel dormice Muscardinus avellanarius: testing predictions from optimal foraging theory. [PDF]
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

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

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

The use of optimal foraging theory in archaeology has been criticized for focusing heavily on “negative” human-environmental interactions, particularly anthropogenic resource depression, in which prey populations are reduced by foragers’ own foraging ...

Dynamic optimal foraging theory explains vertical migrations of Bigeye tuna [PDF]
AbstractBigeye tuna are known for remarkable daytime vertical migrations between deep water, where food is abundant but the water is cold, and the surface, where water is warm but food is relatively scarce. Here we investigate if these dive patterns can be explained by dynamic optimal foraging theory, where the tuna maximizes its energy harvest rate ...

Optimal foraging and the information theory of gambling [PDF]
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 ...
