Cities are home to a continuum of species that range from those specially adapted to exploit urban habitats, to others passing through as transient dispersers. Urbanization often has a profound impact on the movement and gene flow of these species. Compared to natural landscapes, urban environments are complex matrices of roads, buildings, bare soil, slopes, green space, and subterranean infrastructure. Urban neighbourhoods also vary greatly in their socioeconomic and cultural characteristics. This heterogeneity can lead to complex movement patterns in wildlife that are difficult or impossible to characterize using direct tracking methods. Population genetic analyses provide powerful approaches to evaluate spatial patterns of genetic variation and even signatures of adaptive evolution across the genome. When analysed with landscape, environmental, and socioeconomic data, genetic approaches may also identify which features of urban habitats impede or facilitate gene flow. These landscape genetic approaches, when paired with high-resolution sampling and replicated studies across multiple cities, identify dynamic processes that underpin wildlife movement in cities. This chapter reviews the use of spatially explicit genetic approaches in understanding urban wildlife movement, and highlights the many insights gained from rodents in particular as models for urban landscape genetics.
