title: Data from: Comparative landscape genetic analyses show a Belgian motorway to be a gene flow barrier for red deer (Cervus elaphus), but not wild boars (Sus scrofa)

description: While motorways are often assumed to influence the movement behaviour of
 large mammals, there are surprisingly few studies that show an influence
 of these linear structures on the genetic make-up of wild ungulate
 populations. Here, we analyse the spatial genetic structure of red deer
 (Cervus elaphus) and wild boars (Sus scrofa) along a stretch of motorway
 in the Walloon part of Belgium. Altogether 876 red deer were genotyped at
 13 microsatellite loci, and 325 wild boars at 14 loci. In the case of the
 red deer, different genetic clustering tools identified two genetic
 subpopulations whose borders matched the motorway well. Conversely, no
 genetic structure was identified in the case of the wild boar. Analysis of
 isolation-by-distance patterns of pairs of individuals on the same side
 and on different sides of the motorway also suggested that the road was a
 barrier to red deer, but not to wild boar movement. While telemetry
 studies seem to confirm that red deer are more affected by motorways then
 wild boar, the red deer sample size was also much larger than that of the
 wild boars. We therefore repeated the analysis of genetic structure in the
 red deer with randomly sub-sampled datasets of decreasing size. The power
 to detect the genetic structure using clustering methods decreased with
 decreasing sample size.
