Population genetic structure of black rats in an urban environment : a case study in Cotonou, Benin
The cosmopolitan black rat, Rattus rattus, has invaded many cities throughout the world. Although the species is responsible for major damages to food stocks and crops and is involved in the maintenance, circulation and transmission of many zoonotic pathogens to humans and animals, a lot remains to...

The cosmopolitan black rat, Rattus rattus, has invaded many cities throughout the world. Although the species is responsible for major damages to food stocks and crops and is involved in the maintenance, circulation and transmission of many zoonotic pathogens to humans and animals, a lot remains to be known about its eco-evolutionary characteristics, especially in highly modified environments like the urban habitat. In particular, very few studies were conducted on the genetic structure of urban black rat populations, which is yet a prerequisite for defining effective management units. Here, we focus on the population genetics of Rattus rattus in Cotonou, Benin.
