Understanding how sympatric species with similar requirements coexist is a major issue in ecology. A community with more resource sharing or greater niche overlap, will support more species than one with less. In this regard, the principle of competitive exclusion predicts that species will exhibit segregation mechanisms to coexist. In the Humboldt Current System (HCS) in Peru, South American sea lions (SASL, Otaria byronia) coexist with South American fur seals (SAFS, Arctocephalus australis). However, trophic, temporal and spatial partitioning while foraging remains unclear. This study takes place in Punta San Juan (PSJ) national reserve (15 ° 22'S, 75 ° 12'W) in Peru, there are important breeding colonies of the two species of otariids, ...
