Resumen del producto

The Guadalupe fur seal Arctocephalus townsendi (GFS) is known in Latin America as the lobo fino de Guadalupe, oso marino de Guadalupe, or lobo de dos pelos de Guadalupe. Guadalupe Island (GI), off the coast of Baja California, México, is the typical locality where this species occurs; the taxon was first described by Merriam (1897) based on a specimen collected on the island’s west coast. Presently, the GFS distribution is centered on GI (Fleischer 1987, Gallo-Reynoso 1994, Belcher and Lee 2002, AuriolesGamboa et al. 2010); however, another colony has been growing rapidly on the San Benito Archipelago (SBA) since 1997 (Maravilla-Chavez and Lowry 1999, Aurioles-Gamboa et al. 2010, García-Capitanachi 2011). The SBA is a group of three islands (East, Center, and West) and several islets and was home to a large GFS rookery prior to the population’s decimation by the sealing industry. From the late 1700s to 1848, thousands of animals were killed on several islands on the Pacific coasts of México and the United States (Hubbs 1979). A few remaining individuals were harvested in Mexican waters in the late 1800s (Townsend 1931), earning the species near extinct status (Hubbs 1956)
