Stoichiometric theory in optimal foraging strategy
Journal of Mathematical BiologyUnderstanding how organisms make choices about what to eat is a fascinating puzzle explored in this study, which employs stoichiometric modeling and optimal foraging principles. The research delves into the intricate balance of nutrient intake with foraging strategies, investigating quality and quantity-based food selection through mathematical models.

Integrating optimal foraging and optimal oviposition theory in plant–insect research
Oikos, 2002The current approach for studying host selection by phytophagous insects is mainly based on optimal oviposition theory, i.e. the preference–performance hypothesis. Almost no attention has been given to optimal foraging theory. However, recent papers and additional evidence given in this work illustrate that also optimal foraging may shape host ...

Honeyeater foraging: A test of optimal foraging theory
Animal Behaviour, 1981Abstract Honeyeaters (Meliphagidae) were observed foraging for nectar from Lambertia formosa inflorescences, each of which has seven flowers. The frequency distribution of numbers of flowers probed per visit to an inflorescence was found to be bimodal, with one peak at two and the other at seven.

Optimal Foraging Theory: A Critical Review
Annual Review of Ecology and Systematics, 1984Proponents of optimal foraging theory attempt to predict the behavior of animals while they are foraging; this theory is based on a number of assump tions ( 133 , 155 , 2 10, 23 1 ) . First, an individual's contribution to the next generation (i.e. its "fitness") depends on its behavior while foraging.

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 ...

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 ...

Testing optimal foraging theory models on benthic divers
Animal Behaviour, 2016Empirical testing of optimal foraging models on diving air-breathing animals is limited due to difficulties in quantifying the prey field through direct observations. Here we used accelerometers to detect rapid head movements during prey encounter events (PEE) of free-ranging benthic-divers, Australian fur seals, Arctocephalus pusillus doriferus.

Oecologia, 1989
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

Archeology and Optimal Foraging Theory: Appropriate Analytical Units
American Anthropologist, 1985Contrary, then, to Lancy and Strathern, I assume that each label in a pair has fit in a definition structure that contains a category beneath which the label from the pair is attached. This assumption would not be necessary if twos were idioms; in such a case their meanings would not be inferable from their constituent parts.
