Linear regression models relate degree and eigenvector centrality to the proportion of genetically identified immigrants as well as snow depth and coniferous forest cover. P-values were generated by randomly permuting the dependent variable and are the proportion randomly generated parameter estimates that were more extreme than those generated from the data.
