– Animal body size, and in particular body mass (live weight), determines many biological and ecological traits including food intake, metabolism, thermoregulation, generation time, longevity, growth rate, home range size, reproductive strategy, extent of sexual dimorphism and even extinction risk (e.g. Peters 1983; Damuth & MacFadden 1990).
