Carnivore home-range size, metabolic needs and ecology

Abstract

Relationships 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, habitat, diet and zonation) only diet shows a significant influence on home-range size. Carnivores with a large proportion of flesh in their diets have particularly large home-ranges. Intraspecific variation in feeding patterns as a determinant of variation in home-range size is emphasized. © 1982 Springer-Verlag.
