“…High genetic diversity was revealed for all analyzed beech populations (mean A R : 3.5, mean H o : 0.515, mean H e : 0.498), and no signs of inbreeding were detected. Genetic diversity values were similar to other studies based on EST-SSRs in beech [18,39,40]. Among the diversity indices, only allelic richness (A R ) was significantly higher in F. orientalis (mean A R : 3.7) compared to F. sylvatica (mean A R : 3.3).…”

Two subspecies of European beech (Fagus sylvatica L.) can be found in southeast Europe: Fagus sylvatica ssp. sylvatica L. and Fagus sylvatica ssp. orientalis (Lipsky) Greut. & Burd. (Fagus orientalis Lipsky). In a previous study, based on genetic diversity patterns and morphological characters, indications of hybridization between both subspecies were found in northeastern Greece, a known contact zone of F. sylvatica and F. orientalis. Nevertheless, potential genetic admixture has not been investigated systematically before. Here, we investigated genetic diversity and genetic structure of 14 beech populations originating from Greece and Turkey as well as of two reference F. sylvatica populations from Germany based on nine expressed sequence tag-simple sequence repeat (EST-SSR) markers. Very low genetic differentiation was detected among F. sylvatica populations (mean GST: 0.005) as well as among F. orientalis populations (mean GST: 0.008), but substantial differentiation was detected between populations of the two subspecies (mean GST: 0.122). Indications for hybridization between both subspecies were revealed for one population in Greece. One of the genetic markers showed specific allele frequencies for F. sylvatica and F. orientalis and may be used as a diagnostic marker in future studies to discriminate both subspecies.

“…Also, there is evidence of one of the highest resilience of the Sub-Mediterranean beech (H1) in comparison to most continental types at low to mid altitudes. At the present, there is confirmed evidence of inherited more adaptive behaviour of beech to droughts in favour of southern populations [50] but looking over a relatively large spatial scale (Germany, Croatia, Bulgaria and Greece). Providing more spatially intensive, ecosystem specific and a confirmatory explanation of beech adaptation, based on aforementioned results could be of the huge benefits for the forest management in the future to cope with the challenges of the global warming.…”

“…Results from modelling under different climate change scenarios predict a northward drift of the species range (Thuiller et al 2006;Bellard et al 2012;Falk and Hempelmann 2013) and the extinction of populations and a reduction of the range at the southern edge (Geßler et al 2006;Dounavi et al 2016). The climatic conditions in the north-eastern part of the present distribution range will become more favourable for beech.…”

Distribution of genetic diversity in Fagus sylvatica at the north-eastern edge of the natural rangeKempf M., Konnert M. (2016). Distribution of genetic diversity in Fagus sylvatica at the north-eastern edge of the natural range. Silva Fennica vol. 50 no. 4 article id 1663. 17 p. http://dx.doi.org/10.14214/sf.1663. Highlights• European beech at the north-eastern edge of its natural range in Poland have a high level of genetic variation, similar to the populations from Central Europe.• The differences between the beech provenances from the two centres in Poland, which were previously identified on the basis of pollen analyses and phenotypic traits, have now been genetically confirmed. AbstractAn understanding of the genetic variation of the beech, especially at the edge of its natural distribution, is essential because of the change in natural distribution of the species resulting from changing climatic conditions. The main aim of the study was to determine the level of genetic diversity of European beech at the north-eastern edge of its natural range. The other aim was to check the genetic variation of beech from the two centres, the north and the south of Poland, which were identified in previous findings based on pollen analyses and phenotypic traits. The research material was the progeny of twelve beech provenances. The genetic structure of the populations was determined by ten highly variable microsatellite DNA loci. The results confirmed the high genetic diversity of beech at the north-eastern edge of its natural distribution, which infers the probability of their good adaptation to the changing climate and an extension of the range. Genetic analyses confirmed the existence of two genetic centres for beech in Poland. The populations from south-eastern Poland had a slightly higher diversity than the populations from the north-western area, which may indicate that the colonisation of Poland occurred by two routes. The results are important for creating the borders of the provenance regions and for limiting the transfer of seeds and seedlings. The choice of forest reproductive material, based on the knowledge of genetic diversity, is very important for the stability of future forests.
