Is Satisficing an Alternative to Optimal Foraging Theory?
Oikos, 1993Ward (1992; Oikos 63: 312-317) recently argued that optimal foraging theory suffers from a lack of alternative models and suggested that satisficing might serve as such an alternative. We disagree with both premises and argue that the optimal foraging approach generates multiple alternative and testable hypotheses within its own logical framework ...

A Novel Particle Swarm Optimizer Using Optimal Foraging Theory
2006Based on the research of optimal foraging theory (OFT), we present a novel particle swarm optimizer (PSO) to improve the performance of standard PSO (SPSO). The resulting algorithm is known as PSOOFT that makes use of two mechanisms of OFT: a reproduction strategy to enhance the ability to converge rapidly to good solutions and a patch-choice based ...

The foraging behavior of the subterranean mole rat Spalax ehrenbergi (Rodentia, Spalacidae) was tested according to the framework of optimal foraging theory. We compared the frequencies of food species hoarded in storage chambers of mole rats with the frequencies of these species occurring in the vicinity of the mole rats' nest mounds during the winter

A general version of optimal foraging theory: The effect of simultaneous encounters
Theoretical Population Biology, 1984In der Literatur findet man eine Reihe von mathematischen Modellen für die Vorgangsweise, die ein Tier bei der Auswahl seiner Nahrung anwendet. Auch die vorliegende Arbeit entwickelt ein derartiges Modell, und zwar wird dabei im Gegensatz zu den bisherigen Modellen auch die Situation berücksichtigt, wo dem Tier eine Auswahl aus mehreren gleichzeitig ...

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 ...

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 ...

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.

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 ...
