Weak Geographical Structure of Juniperus sabina (Cupressaceae) Morphology despite Its Discontinuous Range and Genetic Differentiation

Abstract: In Europe, Juniperus sabina L. is a mountainous, rare species that creates small, scattered populations, suggesting their refugial nature. Recently, a new variety of this juniper, J. sabina var. balkanensis R. P. Adams et A. N. Tashev was described based on genetic studies. We expected morphological differentiation among isolated parts of the species range and between varieties, as was the case with other Mediterranean junipers. Cones, seeds and fragments of shoots from a total of 506 individuals were collecte… Show more

“…Although the juniper varieties are distinct based on the cpDNA markers, the population structure inferred from the nuclear microsatellites was unclear, since some genetic clusters included geographically distant populations or populations with different ploidy levels. Nevertheless, this outcome was congruent with the previous population structure assessment based on the SNP and SilicoDArT markers [14] and morphological parameters [22]. We suppose that clonal propagation, inbreeding and limited gene flow between populations occupying different mountain ranges contribute to a moderate genetic variation of the J. sabina populations.…”

“…Morphological analyses showed a striking similarity between the KYR individuals and var. sabina from Europe [22]. The morphological differences among J. sabina populations across the vast region from Europe to Kyrgyzstan appear to be primarily shaped by geographical factors rather than taxonomic distinctions.…”
