  1. Populations sharing the same habitat-type were pooled on different geographical scales. B: Belgium; NL: the Netherlands; NW-F: Northwest France.
  2. 1Locus detected as significant outlier locus using a threshold of posterior odds (PO) >10 or P(α ≠ 0) > 0.91; 'strong evidence' for selection.
  3. 2The FST cut-off value for significant outlier detection was set to 0.99.
