Significance in multiple tests for selection suggest diversity at SNP loci from four genes may reflect local adaptation.

FST: Wright's fixation index estimated in Fdist or Bayescan.p-val Fdist: significance of outlier test with hierarchical structure.ENV: component variables derived from environmental data.p-valueWald = significance of Wald test in SAM.p-value LRT = significance of likelihood ratio test in SAM.Log(odds): logarithm (base 10) of Posterior Odds for alternative model in BayeScan and the MCMC method of Coop et al. 2010.p-valGLM: significance of association test with environment in Tassel.R2 GLM: proportion of environmental variance explained by SNP in Tassel.R2 Mantel: correlation between environment and SNP FST matrices.p-valMantel: significance of Mantel correlation.*Significance level (α) for partial Mantel test while performing Bonferoni correction was 0.001.
