“…A cline may originate when gene flow after secondary contact between two genetically distinct populations leads to continuous changes in allele (or DNA molecular marker) frequencies (Breitenbach-Dorfer et al, 1996;Barton and Hewitt, 1985). In other words, a clinal distribution will confirm the Holocene migrations of some forest species -in opposite directions -in the Western Carpathians from Quaternary forest refugia, as postulated elsewhere (Konnert and Bergmann, 1995). Nei's D genetic distance between sympatric Targowiska TS and allopatric SA Sianki populations, the lowest at 0.0259 (see Figs.…”

Aconitum lasiocarpum (Carpathian endemic) and A. variegatum (European endemic) occur sympatrically in the Polish Western Carpathians. Here their taxonomic hybrid A. ×pawlowskii occurs. The aim of this study was to determine the relationship between the taxonomic (Linnaean approach) and genetic structure (PCR-ISSR analysis) of the populations and individuals in two allopatric and four sympatric populations. We determined 309 individuals (OTUs) to species, subspecies and nothospecies using the Linnaean system of classification, and then genetically fingerprinted 39 randomly chosen OTUs. Comparison of the Nei and Li distances obtained from ISSR and morphological matrices using the Mantel test indicated a significant correlation (n = 39, r = 0.53, P = 0.001). Genetic analysis (NEWHYBRIDS) pointed to 7 OTUs as being later-generation hybrids (B1 introgessants) in the sympatric area. Five of them belong to A. variegatum, indicating cryptic introgression, and two belong to A. ×pawlowskii. Nonmetric multidimensional scaling (NDMS) showed gene flow between A. lasiocarpum and A. ×pawlowskii. Allopatric, morphologically pure A. lasiocarpum and A. variegatum populations differed significantly in their ISSR profiles (Fischer's R×C test, P < 0.0001). Expected heterozygosity (Hj) was significantly (p=0.05) lower in allopatric (0.1261-0.1268) than in sympatric populations (0.1348-0.1509), indicating a genetic melting pot in sympatry. The results support the existence of a natural interspecific hybrid swarm zone in the sympatric area of occurrence of Aconitum, and the taxonomic circumscription of the nothospecies within the Linnaean taxonomic system.

“…1a,b). Those two areas are at the border between the Eastern and Western Carpathians, where the two Holocene migratory elements met from the west and southeast (Konnert and Bergmann, 1995;Mráz and Szeląg, 2004;Mráz et al, 2007).…”

“…According to Kral (1982) and Kramer (1984) the re-immigration from the southern Italy refuge was the main mechanism in this process. Konnert & Bergmann (1995) suggest that some migration also took place from refuges in central or eastern France and in the southern Balkan Peninsula. The consecutive postglacial cooling and warming periods during the Holocene were reflected in stops and expansion phases of silver fir along the migration route (Huntley & Birks, 1983).…”

Geographical cline of DNA variation within the F intersterility group of Heterobasidion annosum in Italy

et al. 1997

Eighty‐six Heterobasidion annosum isolates, mainly belonging to the F intersterility group and obtained from 32 different geographical localities in Italy, were subjected to genetic analysis by the Random Amplified Polymorphic DNA (RAPD) markers. The similarity between F and S groups was higher than that between F and P. In UPGMA Cluster Analysis, the F isolates originating from the same locality usually grouped in the same cluster. The isolates also showed a tendency to group at the level of larger geographical areas. Within the F group, isolates from the south of the Italian peninsula showed the highest genetic variation and northern isolates from the Alpine regions showed the lowest. This indicates a gradual cline along the peninsula. The genetic variability in the Italian F group is discussed in relation to the past and present distribution of the host species in Italy and Europe.

The genetic population structure of Polyommatus coridon (Poda 1761) over large regions of France, Italy and Germany was studied by allozyme electrophoresis. The genetic diversity within populations was high for all parameters analysed (number of alleles 2.72; observed and expected heterozygosity 19.6% and 20.3%, respectively; percentage of polymorphic loci: total: 76.4% and, with polymorphism if the frequency of the commonest allele is below 95%: 53.1%), whereas genetic differentiation between populations was comparatively low (F ST = 0.021 ± 0.002). The mean number of alleles declined significantly from southern to northern populations (r = −0.53, P = 0.0005). Similar effects were found also for other parameters of genetic diversity. This is interpreted as a loss of genetic diversity during postglacial
