A Convex Hull-Based Estimator of Home-Range Size
Biometrics, 1995This paper considers the problem of estimating the home-range size of an animal from locational data, which are usually collected by use of radio telemetry, with convex hull-based estimators. It is shown that the widely used minimum convex polygon has some undesirable characteristics as an estimator, and thus should be used with caution. A method based

Carnivore home-range size, metabolic needs and ecology
Behavioral Ecology and Sociobiology, 1982Relationships between home-range size, metabolic needs of the animals occupying the homerange, and ecology are examined across species in the order Carnivora. Home-range size increases with metabolic needs, irrespective of taxonomic affinity. When the effects of metabolic needs are removed, among ecological variables (including activity pattern ...

Energetic constraints on mammalian home‐range size
Functional Ecology, 2019Abstract The metabolic theory of ecology predicts that rates of metabolic processes play a central role in constraining important fitness traits such as home‐range size. Locomotory behaviours are physiologically expensive, yet the relative importance of the animal's energetics in determining their home ranges is unknown.

Analysis of Variability in Home-Range Size of the American Marten
The Journal of Wildlife Management, 1989Analyse des causes possibles de la variation de la taille des aires de deplacement pour la marte americaine a partir de donnees de la litterature.On constate une variation entre les aires des mâles mais pas de celles des femelles ainsi qu'une variation en fonction du sexe.Les variations sont egalement etudiees en fonction de la methode et de la duree d'

Home‐range size in large‐bodied carnivores as a model for predicting neandertal territory size
Evolutionary Anthropology: Issues, News, and Reviews, 2016Adult human foragers expend roughly 30–60 kcal per km in unburdened walking at optimal speeds.1,2 In the context of foraging rounds and residential moves, they may routinely travel distances of 50–70 km per week, often while carrying loads.3 Movement on the landscape, then, is arguably the single most expensive item in the activity budgets of hunter ...

Effects of Forage on Home-Range Size of Largemouth Bass
Transactions of the American Fisheries Society, 1983Abstract The influence of supplementary forage on home-range size of largemouth bass Micropterus salmoides was studied via radio-telemetry. Largemouth bass were caught in Cedar Lake, Illinois, tagged, and released back to the lake either at an experimental feeder from which fathead minnows Pimephales promelas escaped at a rate of 10/hour or at a ...

Variation in home-range size of Black-backed Woodpeckers
The Condor, 2014ABSTRACT The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern that is strongly associated with recently burned forests. Black-backed Woodpeckers are known to have variable home-range sizes, yet the ecological factors related to this variation have not been adequately explored and may hold insights into the natural ...

Review and meta-analysis of correlates of home range size in bats
Journal of MammalogyAbstract Home range is an ecological concept that affects many aspects of the life of vertebrates and hence understanding how it varies between species is crucial. Mammalian home range size has been linked to body size and diet, but these studies were based predominantly on terrestrial species and most specifically excluded bats.

Effects of Sample Size on Kernel Home Range Estimates
The Journal of Wildlife Management, 1999Kernel methods for estimating home range are being used increasingly in wildlife research, but the effect of sample size on their accuracy is not known. We used computer simulations of 10-200 points/ home range and compared accuracy of home range estimates produced by fixed and adaptive kernels with the reference (REF) and least-squares cross ...

Sex Drives Intraspecific Scaling of Home Range Size in Mammals
Ecology LettersABSTRACT Understanding variation in home range size (HR) provides important insights into the underlying ecological processes driving space use. However, it remains unclear whether the interspecific allometric scaling of mammals' HR can also be consistently observed within species and for both sexes.
