Mitochondrial phylogeography of the Eurasian beaver Castor fiber L.

abstract：:Factors ranging from ecological opportunity to genome composition might explain why only some lineages form adaptive radiations. While being rare, particular systems can provide natural experiments within an identical ecological setting where species numbers and phenotypic divergence in two closely related lineages ar...
