抄録

A phylogeographic study of two species of Carpinus, C. japonica Blume and C. tschonoskii Maxim. (Betulaceae), based on the distribution patterns of their chloroplast DNA haplotypes, is reported. In Japan, these species are mainly distributed in Pacific-type deciduous broad-leaved forests. Using 439-440 and 627-629bp nucleotide sequences of noncoding regions of chloroplast DNA, we detected 5 and 6 haplotypes among 217 and 181 individuals sampled from 52 and 49 populations of C. japonica and C. tschonoskii, respectively. The geographic distribution patterns of the haplotypes were highly structured. We investigated the common phylogeographic patterns between the two species that would indicate the influence of common historical factors such as climate change since the last glacial maximum (LGM). Based on our results, we concluded that the Pacific-type Japanese deciduous broad-leaved forests were split into at least three refugia during the LGM. After the LGM, the species expanded to northern areas or moved to higher altitudes from each refugium, thus now occupying northeastern, central, and southwestern Japan.
