title: Data from: Urban landscape genetics: canopy cover predicts gene flow between white-footed mouse (Peromyscus leucopus) populations in New York City

description: In this study, I examine the influence of urban canopy cover on gene flow
 between 15 white-footed mouse (Peromyscus leucopus) populations in New
 York City. Nm calculated from F_ST and recent migration estimated in
 BayesAss+, but not historic migration estimated in Migrate-n, exhibited
 significant isolation-by-distance (IBD). Gene flow was also associated
 with “effective distances” between populations that were calculated based
 on percent canopy cover using two different approaches: 1)
 isolation-by-effective-distance (IED) that calculates the single best
 pathway to minimize passage through high-resistance (i.e. low canopy
 cover) areas, and 2) isolation-by-resistance (IBR), an implementation of
 circuit theory that identifies all low-resistance paths through the
 landscape. IBR, but not IED, models were still significantly associated
 with all three measures of gene flow after factoring out the influence of
 IBD using partial Mantel tests. In cases where both IBR and IED explained
 gene flow independently of IBD, an additional partial Mantel test
 indicated that the IBR models still explained gene flow after factoring
 out IED. The IBR models that explained the most variation in recent
 migration after factoring out IBD (r = 0.70 – 0.90) included landscape
 cells with at least 60-80% canopy cover as low resistance habitat. These
 results have implications for understanding the impacts of urbanization
 trends on native wildlife, as well as for urban reforestation efforts that
 aim to improve urban ecosystem processes.
