Behavioural Constraints to Home Range Allometries in Aquatic Organisms.

ABSTRACT: Home range is the spatial evolutionary arena where an individual can succeed or fail. Its size reflects the balance between individual energy requirements and acquisitions. Since various behavioural traits can affect individual energy demand, we investigated how these traits affect individual space-use behavior and resulting home range size of aquatic organisms. We compiled data for 172 freshwater and marine species, ranging from invertebrates to marine mammals, spanning 8 orders of magnitude in body size and 13 in home range size. Across all taxa, home range size scaled allometrically with body size (R ² = 0.78, exponent = 1.68 ± 0.07). Behavioural traits explained an additional 27.15% of the variance beyond that explained by body size alone. In particular, carnivorous a
