Fig. 4From: Post-glacial phylogeography and evolution of a wide-ranging highly-exploited keystone forest tree, eastern white pine (Pinus strobus) in North America: single refugium, multiple routesGeographic distribution of the most abundant chloroplast haplotypes in eastern white pine populations. Colours correspond to individual haplotype. Yellow, Haplotype S; Red, Haplotype V; Green, Haplotype AG; Black, Haplotype AJ; Blue, Haplotype AP.
