Abstract: <p>Polar bears are generally described as solitary, but features of their life cycles and </p><p>habitats regularly necessitate interaction. Effective conspecific assessment, including accurate </p><p>recognition and discrimination, likely confers benefits, especially to females accompanied by </p><p>dependent young.

Abstract: <p>Consequences of habitat loss and fragmentation include smaller effective population sizes and decreased genetic diversity, factors that can undermine the long-term viability of large carnivores that were historically continuously distributed. I evaluated the historical and contemporary genetic structure and diversity of American black bears (<italic>Ursus americanus</italic… more
