چکیده
391 FORUM FORUM FORUM FORUM is intended for new ideas or new ways of interpreting existing information. It provides a chance for suggesting hypotheses and for challenging current thinking on ecological issues. A lighter prose, designed to attract readers, will be permitted. Formal research reports, albeit short, will not be accepted, and all contributions should be concise with a relatively short list of references. A summary is not required.

Food hoarding: future value in optimal foraging decisions
Traditionally, optimal foraging theory has been applied to situations in which a forager makes decisions about current resource consumption based on tradeoffs in resource attributes (e.g. caloric intake versus handling time). Food storage, which permits animals to manage the availability of food in space and time, adds a complex dimension to foraging decisions, and may influence the predictions...
متن کاملOptimal Foraging Theory Revisited
Optimal foraging theory explains adaptation via natural selection through quan-titative models. Behaviors that are most likely to be favored by natural selection canbe predicted by maximizing functions representing Darwinian fitness. Optimizationhas natural applications in engineering, and so this approach can also be used to de-sign behaviors of engineered agents. In this thesi...
متن کاملSize, foraging, and food web structure.
Understanding what structures ecological communities is vital to answering questions about extinctions, environmental change, trophic cascades, and ecosystem functioning. Optimal foraging theory was conceived to increase such understanding by providing a framework with which to predict species interactions and resulting community structure. Here, we use an optimal foraging model and allometries...
متن کاملEssays on Optimal Foraging Theory: I. the First Two Papers (1966)
The first two papers on optimal foraging theory, one by Robert MacArthur and Eric Pianka and the other by John Merritt Emlen, were published back-to-back in the November-December 1966 issue of the American Naturalist. Both papers are among the most frequently cited papers on foraging theory (having been cited 1079 and 504 times, respectively as of 8-5-05). The circumstances of authorship were d...
متن کاملThe Role of Semantic Clustering in Optimal Memory Foraging
Recent studies of semantic memory have investigated two theories of optimal search adopted from the animal foraging literature: Lévy flights and marginal value theorem. Each theory makes different simplifying assumptions and addresses different findings in search behaviors. In this study, an experiment is conducted to test whether clustering in semantic memory may play a role in evidence for bo...
