Stone martens Martes foina are common occupants of urban environments across continental Europe. We predicted that like other ‘urban adapters’, urban stone martens should exhibit smaller home ranges, more extensive home‐range overlap and higher population densities than their rural counterparts. We radio‐tracked 13 stone martens (10 females, three males) in two towns in southern Luxembourg during a 2‐year period, in order to investigate nocturnal ranging behaviour. All martens maintained stable, year‐round territories almost wholly within the urban perimeter of the respective study towns. Socio‐spatial organization was based on intra‐sexual territoriality. Territories (100% minimum convex polygon) were small in size (males: 112.6±24.8 ha; females: 37.0±22.2 ha) and population densities moderately high (4.7–5.8 adults km −2 ) by comparison with previous studies of rural populations. We conclude that although stone martens are clearly well adapted to urban conditions, urbanization has surprisingly little impact on their socio‐spatial organization by comparison with its effects on other mesocarnivores. This apparent inflexibility in the spacing patterns of stone martens lends support to the view that spacing in martens ( Martes spp.) is a predominantly phylogenetic trait that is under limited environmental influence.
