摘要: Social behavior of adult female Southern Sea Lions, Otaria byronia, was Itudied at Punta Norte (Argentina), during the 1982-85 breeding seuon. Qualitative and quantitative descriptions female-female female-pup aggressive encounters, male intervention on those encounten, copulatory behavior, harding by males. were carried out. Aggressions among females increased directly with deliveries number pups per reproductive group. Resident showed more aggression toward coming from sea than other resident females. Tbese results support hypothesis that aggre· ssive contributes to its pups' survival. Satellite males take over which are sea, although this oo1y oa:assionaly leads copulation, it could probably be interpreted as an alternative strategy. Key W01'ds:social animal interaction, reproduction time.
