Fig. 4From: Purifying selection does not drive signatures of convergent local adaptation of lodgepole pine and interior spruceRelationships between environmental variables and nucleotide diversity of genes in lodgepole pine and interior spruce for the convergent genes, non-convergent top candidate genes and background genes. Panels show the comparison of relationships 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
