Partage de ressource et parenté chez les marmottes à ventre jaune. Resource sharing and kinship in yellow-bellied marmots (Marmota flaviventris).

Résumé

Resource sharing, measured as space-use overlap, is directed primarily toward close kin and does not support the proportional distribution of benefits hypothesis in which benefits are distributed in proportion to the degree of relatedness. Matrilineal formation is the social mechanism whereby female yellow-bellied marmots attempt to maximize inclusive fitness by emphasizing the direct fitness component.
