Distribution map and genetic clustering results of S. koreensis. Pie charts represent the ADMIXTURE Q-values for best the clustering K = 4 result. The sizes of the charts reflect the sample size per population. Genetic barriers among 12 S. koreensis populations, predicted using BARRIER (version 2.2). The genetic barriers are shown in bold red lines. Orange lines indicate Voronoi tessellation which is the optimal arrangement of barriers in the environment to maximize protection. The map source was obtained from the Public Data Portal of the Republic of Korea (data.go.kr), which provides open-source shapefiles (.shp). The map was further refined and customized using QGIS (version 3.42, qgis.org).
