Cytonuclear discordance among Southeast Asian black rats ( Rattus rattus complex)
Abstract Black rats are major invasive vertebrate pests with severe ecological, economic and health impacts. Remarkably, their evolutionary history has received little attention, and there is no firm agreement on how many species should be recognized within the black rat complex. This species comple...

Abstract Black rats are major invasive vertebrate pests with severe ecological, economic and health impacts.
