Abstract: | The study focuses on geographical patterns of genetic variation at allozyme loci common for four main tree species of Central
Europe (Norway spruce, silver fir, common beech and sessile oak). Moving-window averaging of four indicators of allelic richness
and diversity (proportion of polymorphic loci, mean number of alleles per locus, effective number of alleles and expected
heterozygosity) with window size of 50 × 50 km was used to identify the patterns. Moreover, local genetic divergence was assessed
using the G
ST
(Nei, Molecular population genetic and evolution, Amsterdam and Oxford, North-Holland, 1975) and D
j
(Gregorius and Roberds, Theor Appl Genet 71:826–834, 1986) statistics for common beech and silver fir, where raw genotype data were available. Spatial patterns of diversity and allelic
richness were quite similar. Romanian Carpathians were identified as the most important hotspot of genetic diversity and evolutionary
divergence in Central Europe. Implications for genetic conservation are briefly discussed. |
