The predatory larvae of the caddis Plectrocnemia conspersa (Curtis) cause significant prey depletion in a habitat in which prey are patchily distributed. Optimal foraging theory predicts that under these circumstances a predator should stay in any given patch until the prey capture rate there drops to a value equal to the average for the habitat as a ...

Optimal Foraging Theory: A Possible Role for Parasites
Oikos, 1991The role of parasitism has, to date, been largely ignored in optimal foraging theory. The mechanisms necessary to allow animals to use their diet to protect themselves from potential or actual parasitism have been observed in various species. The inclusion of the effects of parasitism on diet choice may considerably improve the predictive powers of ...

A Hunt in New Guinea: Some Difficulties for Optimal Foraging Theory
Man, 1985For one case study the motives for going hunting, the choice of companions and the subsequent distribution of the catch are shown to have been strongly connected. The inquiry strategy of 'optimal foraging theory' takes little account of either motives or distribution.

Revisiting hominin scavenging through the lens of optimal foraging theory
Journal of Human EvolutionScavenging has been a key topic in human evolution for decades, mainly focused on the 'hunting vs. scavenging' debate and the role of meat in the diet of early hominins. Scavenging is frequently considered a marginal activity by archaeologists; however, recent theoretical developments and experimental observations in the field of carrion ecology ...

The role and importance of optimal foraging theory in ecology
1990Ecologists have traditionally been most interested in understanding patterns of species abundance and diversity and the factors that structure populations and communities. On the other hand, behavioural ecologists have concerned themselves mainly with functional explanations of the behaviour of individual animals, the role that ecology plays in ...

It is generally accepted that the Marginal Value Theorem (MVT) describes optimal foraging strategies. Some research findings, however, indicate that in natural conditions foragers not always behave according to the MVT. To address this inconsistency, in a series of computer simulations, I examined the behaviour of four types of foragers having specific
