Fig. 3From: Geographic isolation and climatic variability contribute to genetic differentiation in fragmented populations of the long-lived subalpine conifer Pinus cembra L. in the western AlpsResults of Barrier analysis of genetic discontinuities among, and structure of, the 22 cembra pine (Pinus cembra) populations: a Genetic delimitations in the spatial distribution of populations, visualized with red lines with indicated bootstrap support (%). b Estimated population structures for K = 2, K = 3 and K = 4 genetic groups, based on Mean L(K) (±SD) and ΔK values. Population abbreviations are as explained in Table 1. The natural distribution of cembra pine according to the EUFORGEN (2018) database is marked in dark greenBack to article page
