“…Many U. laevis populations located along Europe have been studied using these markers [17,29,30]. Genetic diversity of a few localized natural populations of U. minor (e.g., in Balearic Islands, [31]; in the Netherlands, [32]; in Croatia, [33]) and U. glabra (e.g., in Denmark, [34]) have also been studied using microsatellite markers. The most extensive analysis of European populations of these two species together, using restriction fragment-length polymorphisms in chloroplast DNA, AFLPs and nuclear microsatellites [16], included only five populations of Wych elm from Spain, of which one was from the Central System.…”

Ulmus glabra Hudson, or Wych elm, occurs as fragmented and relict natural populations in the Central System, which acts as a refugium in the Iberian Peninsula. Considering the importance of the Central System populations of U. glabra, the main objective was to assess their genetic diversity using nuclear microsatellite markers. A total of 360 different genotypes were detected in the 427 U. glabra individuals analyzed. Wych elm populations showed a highly significant genetic differentiation (24%; p = 0.0001). Of the 22 populations studied, population of Rozas de Puerto Real (ROZ) showed the highest values of effective number of alleles (2.803), mean Shannon's diversity (1.047) and expected heterozygosity (0.590). Populations of ROZ and Mombeltrán (MOM) showed the highest values of observed heterozygosity (0.838 and 0.709, respectively), and highly negative values for inbreeding coefficient (−0.412 and −0.575, respectively). Also, most of putative hybrids (50 of 55) were observed in these two populations. Demographic analysis revealed signals for recent (four populations) and ancestral (fifteen populations) bottlenecks. Fragmented populations with diminishing number of individuals, along with anthropogenic intervention and Dutch elm disease (DED), are the main threats to U. glabra populations. From a future perspective, the information generated can be considered in the formulation of conservation strategies for U. glabra populations in the Central System.

“…Another study based on different system markers such as isozymes pointed out a low level of genetic diversity in marginal Finnish U. laevis populations (Vakkari et al 2009 ). Our findings indicate that U. laevis shows lower genetic diversity at nSSRs compared to congeneric species such as U. glabra (Martín del Puerto et al 2017 ; Chudzińska et al 2018 ; Tamošaitis et al 2021 ) and U. minor (Buiteveld et al 2016 ; Zebec et al 2016 ; Chudzińska et al 2019 ; Tamošaitis et al 2021 ).…”

Key message The core populations of the European white elm (Ulmus laevis Pall.) located in Poland maintained slightly higher level of genetic diversity compared to the peripheral populations of this species. Context The most severe threat to elms is the loss of natural habitat under the pressures of agriculture and forestry as well as urbanization. The reductions in European white elm populations as well as populations of other elm species have also been caused by Dutch elm disease (DED). Previous studies have indicated a low level of genetic variation in Ulmus leavis Pall. However, in Poland, the genetic resources and demographic history of U. laevis populations remain poorly documented. Aims The genetic resources of U. laevis in Poland were identified and characterized. Additionally, tests were performed to identify potential bottleneck signatures and effective population sizes of the examined populations. Methods Polymorphism was analyzed using a set of six nuclear microsatellite markers (nSSRs) for 1672 individuals from 41 populations throughout the species range in Poland. Results (1) A moderate level of genetic variation was found. (2) A low genetic differentiation and lack of population structuring were identified. (3) Evidence of reduction in population size was found as a consequence of severe, past bottlenecks. Conclusion The loss of genetic diversity of U. laevis probably occurred in their refugia or shortly after the postglacial recolonization. This loss may have been affected by past DED pandemics similar to those seen at present.
