Habitat Selection and Space Use

2022
This review provides support for the role of both macro- and micro-scale factors driving habitat selection by the little bustard. At a regional scale, little bustard distribution shows a clear relationship with temperature-related variables, but also a strong conspecific attraction and a tendency to philopatry at a local scale, making it especially ...

Habitat selection and the perceptual trap

Ecological Applications, 2010
The concept of “ecological traps” was introduced over three decades ago. An ecological trap occurs when, by various mechanisms, low‐quality (yielding low fitness) habitat is more attractive than good habitat, thus coaxing individuals to settle there despite a resultant loss of fitness. Empirical work on such traps has increased dramatically in the past

The selection of habitats among the monogenea

International Journal for Parasitology, 1998
The pressures responsible for the selection of "non-ectoparasitic" habitats in the Monogenea are discussed. It is suggested that certain monogeneans have become internal to reduce the pressures exerted by predators of ectoparasites rather than to avoid competition with other ectoparasites or to have access to better resources.

Habitat selection by helminths: a hypothesis

Parasitology Today, 1990
How 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.

Habitat Selection in a Clonal Plant

Science, 1985
Rhizomatous growth may permit the nonrandom placement of ramets into different environments, but whether clonal plants are able to use this means to exercise adaptive habitat choice is not known. Western ragweed (Ambrosia psilostachya) plants are shown to preferentially colonize nonsaline soil over saline soil patches, and clones with the strongest ...

A dynamic habitat selection game

Mathematical Biosciences, 1990
A 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, 1973
Abstract 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
