Population genetics of the Brown Rat (Rattus norvegicus) in a Heterogeneous Urban Landscape

Rattus norvegicus, a globally distributed invasive species, has successfully established urban populations in close association with humans posing significant economic and public health challenges worldwide. Understanding the relationship between landscape features and genetic differentiation among R. norvegicus populations is crucial for developing effective control and management strategies. The aim of this study was to analyze the genetic connectivity among R. norvegicus populations in different urban environments of the Metropolitan Area of Buenos Aires including parks, urban reserves, port areas, informal settlements, and residential neighborhoods.
