Worker bees forage nectar not only for themselves, but for their whole hive community. Optimal foraging theory predicts that this bee will forage in a way that will maximize its hive's net yield of energy. Optimal foraging theory (OFT) is a behavioral ecology model that helps predict how an animal behaves when searching for food. Although ...

The DRM went largely unnoticed, but a recent paper by Van Gils [2] describes how red knots Calidris canutus forage based on digestive bottlenecks and confirmed their foraging according to the DRM rather than the CM model of optimal foraging. The case is particularly interesting as a major difference in individual foraging behavior is related to ...
Optimal foraging theory (OFT) was first proposed in 1966, in two papers published independently, by Robert MacArthur and Eric Pianka, [25] and by J. Merritt Emlen. [26] This theory argues that because of the key importance of successful foraging to an individual's survival, it should be possible to predict foraging behavior by using decision ...
Information foraging is a theory that applies the ideas from optimal foraging theory to understand how human users search for information. The theory is based on the assumption that, when searching for information, humans use "built-in" foraging mechanisms that evolved to help our animal ancestors find food.
They are known to forage in “patchy” environments, and research has shown that their behavior can be modeled by optimal foraging models, including the MVT. In a 1977 study by R.A. Cowie, [ 3 ] birds were deprived of food and then allowed to forage through patches in two different environments (the environments differed only in distance ...
As an optimal foraging model, the Ideal Free Distribution predicts that the ratio of individuals between two foraging sites will match the ratio of resources in those two sites. This prediction is similar to the Matching Law of individual choice, which states that an individual's rate of response will be proportional to the positive ...
Dr John D. Goss-Custard is a British behavioural ecologist; he was one of the first scientists to carry out field work on foraging behaviour making use of optimising models, specifically the optimal diet model.
