  abstract = {{H}uman population migrations, as well as long-distance trade activities, have been responsible for the spread of many invasive organisms. {T}he black rat, {R}attus rattus, has colonized most of the world following ship-mediated trade. {O}wing to its tight association with human infrastructures, this species has been able to survive in unfavourable environments, such as {S}ahelian {A}frica. {I}n this work, we combined interview-based and population genetic surveys to investigate the processes underlying the ongoing invasion of south-western {N}iger by black rats, with special emphasis on the capital city, {N}iamey. {O}ur trapping and interview data are quite congruent, and all together point towards a patchy, but rather widespread, current distribution of {R}. rattus. {G}enetic data strongly suggest that road network development for truck-based commercial flow from/to international harbours located in neighbouring countries ({B}enin, {T}ogo, and {N}igeria) facilitates the passive dispersal of black rats over a long distance through unfavourable landscapes. {A}nother potentially, more ancient, invasion route may be associated with boat transport along the {N}iger {R}iver. {H}uman-mediated dispersal thus probably allows the foundation of persisting populations within highly anthropized areas while population dynamics may be more unstable in remote areas and mostly depends on propagule pressure.},
