SHORT COMMUNICATION Ancient DNA reveals genotypic relationships among Oregon populations of the sea otter (Enhydra lutris)
Abstract The sea otter has experienced a dramatic population decline caused by intense human harvesting, followed by a century of recovery including relocation efforts to reestablish the species across its former range in the eastern Pacific. Although the otter was historically present along the coa...
