Combined analysis of fourteen nuclear genes refines the Ursidae phylogeny

Molecular Phylogenetics and Evolution, 2008
Despite numerous studies, questions remain about the evolutionary history of Ursidae and additional independent genetic markers were needed to elucidate these ambiguities. For this purpose, we sequenced ten nuclear genes for all the eight extant bear species.

Phylogeny of the bears (Ursidae) based on nuclear and mitochondrial genes

Molecular Phylogenetics and Evolution, 2004
The taxomic classification and phylogenetic relationships within the bear family remain argumentative subjects in recent years. Prior investigation has been concentrated on the application of different mitochondrial (mt) sequence data, herein we employ two nuclear single-copy gene segments, the partial exon 1 from gene encoding interphotoreceptor ...

Phylogenetic Relationships of Bears (the Ursidae) Inferred from Mitochondrial DNA Sequences

Molecular Phylogenetics and Evolution, 1994
The phylogenetic relationships among some bear species are still open questions. We present here mitochondrial DNA sequences of D-loop region, cytochrome b, 12S rRNA, tRNA(Pro), and tRNA(Thr) genes from all bear species and the giant panda. A series of evolutionary trees with concordant topology has been derived based on the combined data set of all of
