Map representations of six conductance surfaces overlaid with genetic samples collected that were used to examine genetic structure patterns in Northern Spotted Owls.

<p>Panel A represents an idealized conductance surface where all regions of the landscape were equally conducive to Spotted Owl dispersal. Panels B through F represent habitat quality determined for points in time spanning 1870 to 2012, with darker pixels representing areas with greater landscape conductance. The straight line drawn on panel A indicates a spatial divide separating sample sets that was resolved using GENELAND [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0201720#pone.0201720.ref014" target="_blank">14</a>].
