Mandible size and shape in extant Ursidae (Carnivora, Mammalia): A tool for taxonomy and ecogeography
The family Ursidae is currently one of the taxonomic groups with the lowest number of species among Carnivora. Extant bear species exhibit broad ecological adaptations both at inter- and intraspecific level, and taxonomic issues within this family remain unresolved (i.e., the number of recognizable...
