A graphical method is discussed which allows a specification of the optimal diet of a predator in terms of the net amount of energy gained from a capture of prey as compared to the energy expended in searching for the prey. The method allows several predictions about changes in the degree of specialization of the diet as the numbers of different prey organisms change. For example, a more productive environment should lead to more restricted diet in numbers of different species eaten. In a…

Foraging decisions in a patchy environment

Natural selection is used to justify an economic approach to foraging behavior. A predator visiting a series of patches, where its own presence depresses the local food availability, should leave

Optimal Foraging on Arbitrary Food Distributions and the Definition of Habitat Patches

The model describes the optimal allocation of time to each point of the habitat and points to the difficulty of delimiting food patches when they need to be defined operationally, because a "patchy" distribution of consumers can overlie a continuous food distribution.

Foraging strategy of a non-omniscient predator in a changing environment (I) model with a data window and absolute criterion

The model with a data window and absolute criterion (SAC) here enables us to treat the situation where the prey abundance in each patch changes over time due to factors other than predation.

Ecological Constraints on Predation by Large Felids

The evolutionary fitness of any predator, whether it is a spider catching insects or a lion hunting buffalo, depends largely on the quality and quantity of its diet. Predatory strategies are shaped

The Nature of Prey Selection by Planktivorous Fish

The nature of prey selection by planktivorous fish is presented as a model and the effects of prey distribution, encounter rate, handling time, capture success, and optimal foraging on food selection are explicit.



A Theoretical Ecological Model of Size Distributions Among Species of Animals

It is suggested that if a really complete faunistic list for a given biotope could be constructed the size distribution by species would approximate the form given by the model.

It is concluded that in the vicinity of the optimum design the vector (LFe, Lcu, AFe, Ace) cannot be varied in an arbitrary manner.

Bioenergetics and the Determination of Home Range Size

The home range size affects population density, which in turn influences the behavior in the population, and the largest hunters appear to have their food habits regulated by considerations of the efficient use of the food materials in their home range.

The ecological theater and the evolutionary play

In the three lectures which give their title to this delightful collection of esays, the author of "The Enchanted Voyage" and "The Itinerate Ivory Tower" turns his attention to the influence of the

Homage to Santa Rosalia or Why Are There So Many Kinds of Animals?

The address of the president of a society, founded largely to further the study of evolution, at the close of the year that marks the centenary of Darwin and Wallace's initial presentation of the theory of natural selection.
