Genetic diversity is important for species' fitness and evolutionary processes but our knowledge on how it varies across a species' distribution range is limited. The abundant centre hypothesis (ACH) predicts that populations become smaller and more isolated towards the geographic range periphery - a pattern that in turn should be associated with decreasing genetic diversity and increasing genetic differentiation. We tested this hypothesis in Adonis vernalis, a dry grassland plant with an extensive Eurasian distribution. Its life-history traits and distribution characteristics suggest a low genetic diversity that decreases and a high genetic differentiation that increases towards the range edge. We analysed AFLP fingerprints in 28 populations along a 4698-km transect from the geographic range core in Russia to the western range periphery in Central and Western Europe. Contrary to our expectation, our analysis revealed high genetic diversity (range of proportion of polymorphic bands = 56-81%, He = 0.168-0.238) and low genetic differentiation across populations (Φ(ST) = 0.18). However, in congruence with the genetic predictions of the ACH, genetic diversity decreased and genetic differentiation increased towards the range periphery. Spanish populations were genetically distinct, suggesting a divergent post-glacial history in this region. The high genetic diversity and low genetic differentiation in the remaining A. vernalis populations is surprising given the species' life-history traits and points to the possibility that the species has been widely distributed in the studied region or that it has migrated from a diverse source in an East-West direction, in the past.

“…Дать характеристику генетическому разнообразию редких видов расте-ний, а также получить данные о межпопуляционном и внутрипопуляционном полиморфизме и генетической структуре популяций позволяет применение молекулярно-генетических методов [8][9][10]. В частности, для характеристики полиморфизма редких видов растений, геном которых практически не изучен, применяют методы мультилокусного анализа, которые позволяют оценить вариабельность большей части генома.…”

Background. Knowledge of genetic diversity within and among populations of rare and endangered plants species is practically important for conservation management. Molecular markers are useful tools for analysis of genetic diversity. In this study ISSR-analysis of rare endemic species Allium regelianum which grows in the Volgograd region was performed for the first time. Materials and Methods. A total of 93 samples from the 11 populations were collected and used in analysis. Six primers used in ISSR-analysis. Data analysis was performed using the GenAlEx 6.41, POPGEN 1.32, PAST 3.11 and STRUCTURE 2.3.1 programs. Results. A total of 109 ISSR-fragments were scored of which 87 (79.8%) were polymorphic. Comparatively high level of intrapopulation diversity was estimated for the population of the area near Krasnoyarskii khutor, Serafimovichskii administrative region, and for the population of Khrenovatyi Liman, Nikolaevskii administrative region of Volgograd Oblast. Genetic similarity index among populations ranged from 0.88 to 0.96. Genetic differentiation among populations of A. regelianum, GST was 0.284, only. Analysis of molecular variance showed that genetic heterogeneity of A. regelianum 83% was attributed to differences within populations and 17% occurred among populations. Principal coordinate analysis and analysis of populations structure (with the used of STRUCTURE program) found no clear differentiation among populations. Conclusion. The estimation of intra- and interpopulation diversity of A. regelianum was performed. ISSRs detected high levels of genetic similarity within the populations of A. regelianum and low level of genetic differentiation among populations.
