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.

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.

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 selectivity of crown-of-thorns sea stars (Acanthaster sp.) for different coral prey types was quantified in the field and laboratory and compared with a range of nutritional and food quality parameters as well as the growth performance of sea stars ...

Strategy maps: Generalised giving-up densities for optimal foraging.
Ecology Letters, 2023Finding a common currency for benefits and hazards is a major challenge in optimal foraging theory, often requiring complex computational methods. We present a new analytic approach that builds on the Marginal Value Theorem and giving-up densities while ...
