  *ABSTRACT: * Groups of male South American sea lions (Otaria flavescens;
SSLs) congregate in harbours on the northern coast of Argentina. These
groups are very dynamic, with a high degree of habituation to human
activities and the ability to colonise different types of artificial
substrates, making them an interesting subject for understanding individual
association patterns and spatiotemporal variations in this species. In the
present study, we recorded the associations between individual
bleach-marked SSLs in the harbours of Mar del Plata (PM) and Puerto Quequén
(PQ) on four different substrate types during four non-breeding seasons. We
found that the association pattern differed between the harbours, with a
well-differentiated social structure being evident in PM but very little
social differentiation occurring in PQ. The observed social structure in PM
may have resulted from passive habitat preference rather than genuine
social behaviour, as the association pattern disappeared when SSLs moved to
sandy beaches within the harbour. Given that these colonies are must-see
tourist attractions but may have negative interactions with human
activities, we recommend considering the association between SSLs and
artificial habitats to design effective management strategies and reduce
potential conflicts
