Conserved Primers for Rapid Sequencing of the Complete Mitochondrial Genome from Carnivores, Applied to Three Species of Bears
Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada
Phylogenetic relationships of the order Carnivora have been extensively studied. However, depending on the type of data, species sampling, and method of analysis used, carnivores have been placed in nearly every possible position throughout the eutherian phylogenetic tree (for a review, see Novacek 1992
). The integrity of the order itself has, however, remained intact. Undisputedly monophyletic, the order Carnivora nonetheless constitutes a very adaptable and heterogeneous group (Wayne et al. 1989
) whose evolution has been marked by several events of parallel or convergent evolution and rapid radiation. Consequently, phylogenetic relationships between and within many carnivore families are also still largely unresolved. For example, the families Procyonidae, Ailuridae, Mustelidae, Pinnidedia, and Ursidae are joined at a polytomy. Within Pinnipedia, the closer affinity of Otariidae to either Phocidae or Obodenidae has long been debated. Additionally, the monophyly of the family Mustelidae has been challenged, with true mustelids and mephitids thought
