Molecular phylogenetics and biogeography of Lepus in Eastern Asia based on mitochondrial DNA sequences
In spite of several classification attempts among taxa of the genus Lepus, phylogenetic relationships still remain poorly understood. Here, we present molecular genetic evidence that may resolve some of the current incongruities in the phylogeny of the leporids. The complete mitochondrial cytb, 12S...
