This study addresses the distribution of the wild service tree Sorbus torminalis (L.) Crantz in the Czech Republic by drawing on publicly available databases and herbarium records. In the Czech Republic, this tree occurs in stands at a proportion greater than 1% in 4350.32 ha of forests; the reduced area of the species is 86.42 ha. However, mapping the biotopes for Natura 2000 showed 3627 segments of biotopes, with the wild service tree occurring in a total area of 31274.4 ha. There are approximately 220179 wild service tree individuals in the Czech Republic. This tree is found at altitudes from 175 to 760 m a.s.l., with the centre between 250 and 450 m a.s.l. It shows no preference for slope orientation and is mostly located at sites with rich, and frequently humus-enriched, soils; however, it is often found at extreme sites with shallow soils in the 1 st -5 th forest altitudinal zones. In the Czech Republic, the wild service tree clearly prefers plant communities of cl. Querco-Fagetea; however, its occurrence was recorded in 10 other classes (20 alliances) of the phytocoenological system. In the conditions of the Czech Republic, natural regeneration of the wild service tree occurs in approximately 55% of the stands in which it is present.

“…Its distribution and altitude dependence differ in various parts of Europe. Although the altitudinal limit in Britain is 300 m (Roper 1993), Belletti et al (2008) reported the wild service tree at 100-1000 m a.s.l. in Italy.…”

“…For instance, only few stems over 185 individuals were found to be the result of vegetative reproduction in a French population of S. torminalis . Some studies may underreport the natural incidence of clonality because they were specifically designed to avoid sampling from the same genets, which prevented precise estimation of the extent of clonality (Belletti et al 2007).…”

“…Although several studies report on the genetic diversity of S. torminalis populations throughout Europe (Demesure et al 2000, Oddou-Muratorio et al 2001a, Hoebee et al 2006, Angelone et al 2007, Belletti et al 2007, studies focusing on peripheral populations of the species are scarce (Rasmussen & Kollmann 2007b). The latter authors found that small populations located at the northern limits were characterized by high clonality and low genetic variation (Rasmussen & Kollmann 2007b).…”

Knowing the level of genetic diversity and structure in marginal plant populations is essential for managing their genetic resources. This is particularly important for rare scattered tree species, such as Sorbus torminalis (L.) Crantz. We investigated the genetic diversity and its spatial distribution in peripheral populations of S. torminalis. As the species is known to reproduce vegetatively, we also evaluated clonal structure within populations. Using 13 nuclear microsatellite loci designed in two multiplexes, we genotyped 172 individuals revealing the existence of 100 distinct genotypes. Number of ramets per genotype was variable across populations with an average of 1.72. Examples of somaclonal variation at particular loci were detected. Measures of genetic diversity of the total sample were relatively high (mean allelic richness AR = 10.293; expected heterozygosity He = 0.756), as compared to other S. torminalis populations. We noticed a slightly negative inbreeding coefficient (FIS = -0.029) indicating a small excess of heterozygotes, which is typical for self-incompatible plants. Genetic differentiation among populations was low (FST = 0.048), but Bayesian clustering methods revealed the existence of three distinct genetic clusters only in part related to population structure. Significant spatial genetic structure within populations was also detected (Sp = 0.0125) indicating fine-scale pattern of isolation by distance. Our study demonstrated that peripheral populations of S. torminalis may exhibit relatively high levels of genetic diversity despite the existence of vegetative propagation. Nevertheless, if the studied or similar populations are expected to be utilized as seed sources for ex-situ or in-situ conservation purposes, the existence of clonal structure and spatial genetic structure must be taken into account in order to avoid excessive sampling of the same or closely related genets.

“…Demography is the main factor influencing genetic histories; nevertheless, neutral markers may present stochasticity in a given demographic context that is modulated by non-stochastic forces such as selection. The influence of the above factors in shaping extant population genetic diversity and structure is of paramount importance in order to secure the adaptive potential of populations and to formulate appropriate management and conservation strategies for sustainability (Tessier du Cros et al 1999;Boshier and Amaral 2004;Belletti et al 2008).…”

Wild cherry (Prunus avium L.) is a widespread, partially asexual, noble hardwood European species characterized by a scattered distribution, small population sizes, and human exploitation for its valuable wood. These characteristics, especially at the southern limits of the species natural distribution where additional varying stresses may occur, render P. avium populations prone to potential stochastic, genetic, and demographic events. In this study, we used dominant inter simple sequence repeat (ISSR) and codominant simple sequence repeat (SSR) markers to infer the genetic structure of P. avium. Five populations from northern Greece were evaluated based on 46 ISSR and 11 SSR loci. Populations presented a relatively high level of genetic variation, with a mean genetic diversity of H e =0.166 and H e =0.740 regarding ISSR and SSR analysis, respectively. We observed moderate population differentiation for ISSR (G ST =0.113) and SSR (F ST =0.097) markers. AMOVA also detected significant differentiation among populations for ISSRs (Φ ST =0.338) and SRRs (Φ ST =0.162). According to linkage disequilibrium analysis, estimates of effective population size were generally sufficient for maintaining extant genetic variability and evolutionary potential. A possible bottleneck was detected for only one population. In general, it appears that despite the particular characteristics of the P. avium populations studied, genetic stochasticity events were not apparent. The studied populations, located at the rear edge of the species European distribution, reveal a wealth of genetic variation that is very valuable for the genetic conservation of local adaptive gene complexes, especially under contemporary climatic change scenarios.
