A model which relates optimal food preference relationships and caloric yield per unit time of potential food sources is derived. It is suggested, on the basis of this model, that: 1) Food preferences can be adequately described only if a number of factors other than relative frequencies in the diet and relative abundances of the food types are known. 2) Animals should be more selective in their choice of foods when satiated or when food is common, more indiscriminate when starved or when food… 

Optimal Food Selection: A Graphic Model

A graphic model for optimal food selection has been developed and conclusions regarding optimal diets, food niche breadth, etc., are consistent with current thought on the subject.

Optimal Diet as a Function of Absolute Abundance, Relative Abundance, and Relative Value of Available Prey

absolute abundance of food is the overriding parameter in the determination of optimal diet, which is the set of kinds of prey which if eaten whenever encountered will maximize the intake of food value per unit time.

Variable ingestion rate and its role in optimal foraging behavior of marine deposit feeders

A previously developed optimal foraging model predicted that ingestion rate and food value should covary positively in order to maximize net time rate of energy gain, and to test this general prediction, the authors fed three species of deposit-feeding polychaetes artifical sediments which varied only in protein content (food value).

The Relationship between Selectivity and Food Abundance in a Juvenile Lizard

It is suggested that energy optimization may be a relatively low priority for small ectothermic insectivores such as Anolis aeneus juveniles, because low energy demands, a relative abundance of suitable prey sizes in the environment, and low search costs may allow such animals to feed more like herbivores than like insectivorous birds or mammals.

Food Preference, Optimal Diet and Reproductive Output in Stoats Mustela Erminea in Sweden

No consistent difference in reproductive success was found in the different food environments, but the highest reproductive output occurred in areas with relatively high water vole density.

Are Rules of Thumb Sufficient for the Starling’s Choice of Food According to Gain in Energy?

If we want to understand the ecological significance of predator-prey relationships, e. g. the impact of birds on insect populations, we must know the population dynamics of the prey species and the

Insect Behavior, Resource Exploitation, and Fitness

It is asserted that the study of food choice in animals, generally called the theory of optimal diets, is still in its infancy; however, since its inception more than a decade ago, interest in optimal diets has grown at an impressive rate.

An Analysis of Diet Selection by Large Generalist Herbivores

A property of this "optimization model" is that the contribution of a food to the diet will sometimes vary with the food's content of a particular nutrient and sometimes will not, which might explain why no consistent relations of this kind have been found experimentally.

Seed Selection in Some North American Finches

The present study deals with seed selection of several species of finches in relation to bill size, seed-husking speed, seed size, caloric content, and rate of caloric intake under two temperature regimes in the laboratory.




The relationship between butterflies and their food plants is investigated, the examination of patterns of interaction between two major groups of organisms with a close and evident ecological relationship, such as plants and herbivores.

Community Structure, Population Control, and Competition

Populations of producers, carnivores, and decomposers are limited by their respective resources in the classical density-dependent fashion and interspecific competition must necessarily exist among the members of each of these three trophic levels.
