“…Studies on Pinus have confirmed that pollen flow may occur even between geographically isolated populations [10,28,44]. Acceptance of the hypothesis about substantial gene flow would simultaneously imply that there should be a strong selection pressure to maintain the climatic races observed by Arbez [1,2] and Løfting [33], as well as the differentiation among populations observed for quantitative traits [26,34,27].…”

“…crown form) and rhythm of growth, Løfting [32,33] found that there is a much stronger differentiation in climatic races for A. nordmanniana than for the nearby related Abies alba, which has a much wider geographic distribution. Studies of Arbez [1,2] on populations from the Turkish part of the distribution area confirmed the presence of highly differentiated climatic races and in Denmark Madsen [34] found that mean flushing date varied 17 days between provenances from Turkey and Georgia. For this reason, the choice of provenance (origin of seed source) is considered important in Christmas tree production, and there is a great interest in finding genetic patterns with molecular markers that can serve as reference in seed source certification.…”

Fifteen populations of Abies nordmanniana, originating from all main parts of its distributional area in the Caucasian region, were genotyped for three chloroplast microsatellites as well as one mitochondrial marker. The chloroplast microsatellites were highly variable, resulting in a total of 111 haplotypes in 361 analysed individuals, while the mitochondrial marker showed no variation. Analysis of molecular variance attributed 2.1% of the variation in the microsatellites to be among populations, and no correlation between geographic distribution and genetic distances among populations could be observed. A simulation study was conducted to investigate to what extent the low genetic differentiation among populations could be a result of size homoplasy in the applied microsatellites. However, the simulations indicated that the low differentiation more likely is caused by high gene flow among populations.

“…Frequent Pleistocene contacts between two species could have contributed to the individualization of A. equi-trojani and rise to the particular morphology of the south-eastern ecotypes of A. alba. Genic exchanges could also be responsible for the emergence of Abies equi-trojani, which has the ecological characteristic of a relatively new population (Arbez, 1969) and strong similarities in its terpene composition to the Romanian provenance of A. alba. The present ecological characteristics of A. equi-trojani, which is a high mountain species growing in humid conditions, are similar to those of A. alba and northern populations of A. bornmuel/eriana.…”

lnfrageneric states and chemosystematic relationships are discussed by using some selected essential oil components and morphometrical characters. Morphologic and morphometric analysis are carried out on 20 Abies population and essential oil analysis on the twig with needle are carried out by using GC. techniques. The qualitative major constituents are found as same in the whole studied species but their quantitative content varies significantly. Inter and intrapopulational variations are found at the high ratio in the Abies taxa. The results are presented in graphical form, allowing patterns of variable intercorrelations and compared with phylogenetic patterns. Tree to tree variation of quantitative terpene composition of the leaf oil is sufficiently to permit chemosystematic discussions and understanding evolutionary phenomenon in the light of literatures.

The eastern‐Mediterranean Abies taxa, which include both widely distributed species and taxa with minuscule ranges, represent a good model to study the impacts of range size and fragmentation on the levels of genetic diversity and differentiation. To assess the patterns of genetic diversity and phylogenetic relationships among eastern‐Mediterranean Abies taxa, genetic variation was assessed by eight nuclear microsatellite loci in 52 populations of Abies taxa with a focus on those distributed in Turkey and the Caucasus. Both at the population and the taxon level, the subspecies or regional populations of Abies nordmanniana s.l. exhibited generally higher allelic richness, private allelic richness, and expected heterozygosity compared with Abies cilicica s.l. Results of both the structure analysis and distance‐based approaches showed a strong differentiation of the two A. cilicica subspecies from the rest as well as from each other, whereas the subspecies of A. nordmanniana were distinct but less differentiated. ABC simulations were run for a set of scenarios of phylogeny and past demographic changes. For A. ×olcayana, the simulation gave a poor support for the hypothesis of being a taxon resulting from a past hybridization, the same is true for Abies equi‐trojani: both they represent evolutionary branches of Abies bornmuelleriana.
