Habitat selection by helminths: a hypothesis
Parasitology Today, 1990How do liver worms find the liver? Why are heartworms always found in the heart? Attempts to answer these questions have invariably yielded inconclusive results. A major problem has been the use of models or hypotheses derived from studies of free-living organisms.

A dynamic habitat selection game
Mathematical Biosciences, 1990A patch selection game is formulated and analyzed. Organisms can forage in one of H patches. Each patch is characterized by the cost of foraging, the density and value of food, the predation risk, and the density of conspecifics. The presence of conspecifics affects the finding and sharing of food, and the predation risk. Optimal foraging theory can be

Habitat selection in a variable environment
Journal of Theoretical Biology, 1973Abstract A Monte Carlo simulation scheme was utilized to determine optimal strategies of habitat utilization in a variable environment. The model allows for differences in quality among habitats at any one time and for varying levels of environmental variance and autocorrelation. When habitats are on the average equal in quality, tracking of temporal

Perspectives of habitat selection
2001In Chapter 4 questions concerning the choice of monitoring habitats are discussed. It is argued that the choice in principle shall be the result of a “case by case” assessment, which in fact is what should be processed during the ecological risk assessment.

1965
Publisher Summary This chapter discusses habitat selection in birds that involves recognition of the habitat and establishment of preferences. An analysis of the manner whereby habitat preferences are fixed are preceded by a study of the sensory capabilities of the animals in question.

Habitat selection by grayling—I. Spawning habitats
Journal of Fish Biology, 1995Grayling spawning sites were investigated in two French rivers, the Pollon (1 year) and the Suran (2 years) and described by current velocity, water depth, and substrate composition, completed by an assessment of bottom shear stress with FST‐hemispheres. A comparison was made between used and available habitats, the latter being characterized by random

Ecology, 1981
A graphical theory of habitat selection is built in steps. The theory treats two species in an environment with two usable patch types in a matrix of unusable space. The first step assumes habitat selection is density independent and free of search costs. The second assumes density independence, and the third assumes neither.

The American Naturalist, 1991
Habitat-selection concepts have rarely been explicitly used for plants, perhaps because the majority of them are immobile. For plants, habitat selection results from evolutionary adjustment of species to environmental factors so that the species functions better in some habitats than in others.

Habitat Selection: Introduction
1990Habitat selection is a key component in the adaptive response of animals to their environments, and it can profoundly influence the selective regime to which the pre-adult and, in some cases, the adult stages of the organisms are exposed.
