Terrestrial habitat preferences and segregation of four pinniped species on the islands off the western coast of the Baja California Peninsula, Mexico
Abstract Coastal habitats are crucial to pinnipeds for resting, molting, and reproduction. We examined terrestrial habitat preferences of four pinniped species (California sea lion, Guadalupe fur seal, harbor seal, and northern elephant seal) on the islands off the western coast of the Baja Californ...
