Northernmost Record of the Galapagos Sea Lion (Zalophus wollebaeki): Sightings Along the Mexican Central Pacific and the Gulf of California During La Niña Conditions

Abstract:

Most organisms within the trophic web are affected by significant fluctuations in sea surface temperature (SST)—from phytoplankton (Fischer et al., 2020) to top predators such as pinnipeds (Elorriaga-Verplancken et al., 2016; Páez-Rosas et al., 2018; Gálvez et al., 2020). The global dis-tribution of these marine carnivores depends on SST because of its effects on the input of nutri-ents, primary productivity, and subsequent prey availability (Guinet et al., 2001; McClatchie et al., 2016; Adame et al., 2020).
