Description
Summary:Determining the scale of genetic variation informs studies of dispersal, connectivity, and population dynamics particularly in heterogeneous landscapes. Mastomys natalensis and Mus minutoides are generalist rodents that utilize multiple habitat types within the agro-ecological landscapes of southern African savannas. To study the comparative spatial genetic structure of these species we developed 9 new microsatellites for Mus and used 14 microsatellite loci previously developed for Mastomys, to genotype rodents sampled across an agro-ecological landscape (˜200 km2). Spatial genetic structure was measured using spatial autocorrelation and Moran’s Eigenvector Maps analysis. In both species, non-random genetic similarity was limited to only the smallest spatial scales (
