| Outline of Final Research Achievements |
We combine an extensive survey of the mitochondrial (mtDNA) and nuclear genomes in 42 populations of the three Japanese Abies species (A. firma, A. homolepis and A. veitchii) with species distribution modelling (SDM). From the Bayesian clustering analysis showed that the three species were clearly separated. On the other hand, mtDNA haplotypes of the four northern populations of A. firma were completely replaced by two major haplotypes of A. homolepis and A. veitchii. The neighbor-net analysis and SDM suggests that the mtDNA capture through historical introgression among species were occurred in each geographic region. We hypothesize that climatic-induced range shifts during the Pleistocene/Holocene may have played an important role in the observed patterns of introgression of these species.
