“…There was no signal of a phylogeographic structure, only that of a weak isolation by distance, confirming the hypothesis of recent differentiation and emergence of distinct lineages. This pattern is reminiscent of that of P. sylvestris, a European pine with broadly similar ecological requirements as black pine (Robledo-Arnuncio et al 2005;Pyhäjärvi et al 2007;Tóth et al 2017).…”

“…Genetic distinctiveness of the southern Tatra populations from Slovakia was found in the studies of Tóth et al (2017a). Based on combining paleoenvironmental data, vegetation modeling and genetic analysis it has been shown that isolation in glacial refugia and migrations significantly affect shaping the modern genetic diversity of Scots pine in Europe (Cheddadi et al 2006).…”

Genetic resources of relict populations of Pinus sylvestris (L.) in Western Carpathians assessed by chloroplast microsatellites

The relict character of the Scots pine populations from the Tatra Mts. (Western Carpathians) was formed on scarcely accessible, ecologically extreme habitats, in areas which were not under human activity. An exhaustive genetic analysis of the Scots pine populations from the refugial locations in the Tatra Mts. (Poland) had not yet been. In this study, we characterize the genetic variation and differentiation of the relict Scots pine populations from the Tatra Mts., to provide information on their genetic resources and the conservation implications. Eight paternally inherited chloroplast microsatellite loci were used to investigate the genetic structure of 4 relict populations, which were compared with the natural populations from the Baltic region (5 populations from Lithuania, Latvia and Estonia) and to a northern range from Russia (5 populations from the Kola Peninsula and Arkhangelsk Oblast). The four relict pine populations were characterized by a lower level of genetic variation when compared to the Baltic and northern populations, which was expressed in lower values of particular genetic parameters: numbers of alleles and haplotypes, haplotype genetic diversity, haplotype differentiation, and mean genetic distance between individuals in the population. Our results revealed a very high and significant genetic differentiation between all the analyzed populations, as well as between the three analyzed regions (PhiPT = 8%). Furthermore, the relict populations within a close geographic location showed higher differentiation (PhiPT = 5%) compared to the northern Russian and Baltic populations that were separated by tens and hundreds of kilometers. The relict populations of P. sylvestris from the Tatra Mts. deserve conservation efforts due to the fact that they are an important component if the species-poor Tatra forests.

Highlights• The European black pine, Pinus nigra (Arnold), has a weak spatial genetic structure.• Gene flow among populations is frequent and populations are often of admixed origin.• Current genealogies result from recent, late Pleistocene or Holocene events. 2 0• Seven modern genetic lineages emerged from divergence and demographic contractions.• These seven lineages warrant a revision of subspecies taxonomic nomenclature. Abstract 2 5Fragmentation acting over geological times confers wide, biogeographical scale, genetic diversity patterns to species, through demographic and natural selection processes. To test the effects of historical fragmentation on the genetic diversity and differentiation of a major European forest tree and to resolve its demographic history, we describe and model its spatial genetic structure and gene genealogy. We then test which Pleistocene event, whether recent or ancient, could explain its 3 0 widespread but patchy geographic distribution using population genetic data, environmental data and realistic demographic timed scenarios.The taxon of interest is a conifer forest tree, Pinus nigra (Arnold), the European black pine, whose populations are located in the mountains of southern Europe and North Africa, most frequently at midelevation. We used a set of different genetic markers, both neutral and potentially adaptive, and either 3 5bi-parentally or paternally inherited, and we sampled natural populations across the entire range of the species. We analysed the data using frequentist population genetic methods as well as Bayesian inference methods to calibrate realistic, demographic timed scenarios.Species with geographically fragmented distribution areas are expected to display strong amongpopulation genetic differentiation and low within-population genetic diversity. Contrary to these 4 0expectations, we show that the current diversity of Pinus nigra and its weak genetic spatial structure are best explained as resulting from late Pleistocene or early Holocene fragmentation of one ancestral population into seven genetic lineages, which we found to be the main biogeographical contributors of the natural black pine forests of today. Gene flow among the different lineages is strong across forests and many current populations are admixed between lineages. We propose to modify the currently 4 5accepted international nomenclature made of five subspecies and name these seven lineages using regionally accepted subspecies-level names.
