The spatial scale of animal space use, e.g. measured as individual home range size, is a key trait with important implications for ecological and evolutionary processes as well as management and conservation of populations and ecosystems. Explaining variation in home range size has therefore received great attention in ecological research. However, few

Movements, home-range size and habitat selection of mallards during autumn migration. [PDF]
The mallard (Anas platyrhynchos) is a focal species in game management, epidemiology and ornithology, but comparably little research has focused on the ecology of the migration seasons.

Estimating home-range size: when to include a third dimension? [PDF]
AbstractMost studies dealing with home ranges consider the study areas as if they were totally flat, working only in two dimensions, when in reality they are irregular surfaces displayed in three dimensions. By disregarding the third dimension (i.e., topography), the size of home ranges underestimates the surface actually occupied by the animal ...

Whitebark pine, population density, and home-range size of grizzly bears in the greater yellowstone ecosystem. [PDF]
Changes in life history traits of species can be an important indicator of potential factors influencing populations. For grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE), recent decline of whitebark pine (WBP; Pinus albicaulis ...

Home range size, vegetation density, and season influences prey use by coyotes (Canis latrans). [PDF]
To ensure reproductive success, Canis species establish contiguous mosaics of territories in suitable habitats to partition space and defend limiting resources.

Home range size variation in female arctic grizzly bears relative to reproductive status and resource availability. [PDF]
The area traversed in pursuit of resources defines the size of an animal's home range. For females, the home range is presumed to be a function of forage availability.

Sex and Age Effects on Monk Parakeet Home-Range Variation in the Urban Habitat
Home-range size is a key aspect of space-use, and variation in home-range size and structure may have profound consequences for the potential impact of damage and control strategies for invasive species.

Home is where the shell is: predicting turtle home range sizes [PDF]
SummaryHome range is the area traversed by an animal in its normal activities. The size of home ranges is thought to be tightly linked to body size, through size effect on metabolic requirements. Due to the structure ofEltonian food pyramids, home range sizes of carnivores are expected to exceed those of herbivorous species. The habitat may also affect

Background Competition within and between social groups determines access to resources and can be inferred from space use parameters that reflect depletion of food resources and competitive abilities of groups.
