摘要: Abstract The Territory Inheritance Hypothesis (TIH) on the evolution of group-living in carnivores considers (1) increased fitness original territory holders when they ensure that will be inherited by a carrier their own genes, and (2) subadult remains at home survives an otherwise saturated environment. A comparison both adults subadults (at different rates population growth adult survival) who either do or not choose strategy building up group, indicates groups are favoured decreasing to slightly increasing populations moderate high (>0.5) annual survival. Furthermore, analysis maximum group size under TIH suggests five more should split up. as explanation for red fox, Vulpes vulpes L., badger, Meles meles is compared with Resource Dispersion (RDH, Macdonald 1983) Constant Size (CTSH, von Schantz 1984a), which consider spatio-temporal fluctuations food supply. RDH best social organization badger; CTSH explain fox data special conditions, but satisfactory general explanations this species; may why group-living, least once it established, stable strategy.
