Predator Switching and the Interpretation of Animal Choice Behavior: The Case for Constrained OptimiThe past decade has seen considerable debate over the choice of methodology appropriate for the analysis of animal behavior. Unquestionably, the dominant approach uses a variety of optimization methods as a basis for modeling behavior.

Overthrow

The Starvation-Predation Trade-Off And Some Behavioural and Ecological ConsequencesThere are a variety of ways in which an animal may increase the amount of food it obtains at the expense of an increase in predation risk. I give some examples:

It is shown that the predictions of the standard model of prey choice do not necessarily hold in other contexts. The second section outlines a more general framework for modelling behaviour.

One assumption of such theories is that an animal that forages according to predictions will acquire more resources, and thus will have higher “fitness”, than a conspecific that fails to forage by the theoretical rules. This assumption is seldom tested in any way directly related to reprodu

Impulsive Control with Fixed-time Impulses,cs (Brown, 1964) and of foraging economics (Stephens and Krebs, 1986) become closely allied. Foraging decisions by the territorial defender may be influenced not only by changing densities of various prey types, but also by other environmental fluctuations, by intrusions from food competitors and pr

With birds eating insects direct observations in the field are rather difficult, therefore we have to rely to a large extent on indirect evidence. Analyses of stomach contents were a first approac
