Fig. 5From: Purifying selection does not drive signatures of convergent local adaptation of lodgepole pine and interior spruceDistribution of strength of correlations (r) between environmental variables and nucleotide diversity of genes. Grey polygons show the density of r values of all genes. Red bars on the x-axis show the r values of convergent genes. Panels show distribution of r values for correlations between nucleotide diversity and: a, f degree-days below 0 °C (DD_0); b, g 30-year extreme minimum temperature (EMT); c, h latitude (LAT); d, i mean temperature of the coldest-month (MCMT); e, j temperature difference between the warmest and coldest months (TD)Back to article page
