| 英文摘要 | Local adaptation to different environments has the potential to maintain divergence between populations despite recurrent gene flow and is an important driver for generating biological diversity. in this study, we investigate the role of adaptation in the maintenance of two parapatric varieties of a forest tree. we used sequence variation of chloroplastic dna and restriction site-associated dna to investigate the genetic structure of two varieties of castanopsis carlesii in subtropical china and relate it to climatic variation. we used niche reconstruction methods to investigate niche differentiation between the two varieties and to estimate the past distribution of this species. a deep divergence was observed between the two varieties, but evidence of introgression and genetic admixture was detected in two phenotypically and geographically intermediate populations. niche reconstruction suggests that the distribution of the two varieties was disjunct during periods of global cooling and that the two varieties occupy significantly different niches. the genetic structure was mainly driven by environmental factors, and 13 outlier loci under divergent selection were correlated with climatic variation. these results suggest that the two varieties evolved in allopatry and came back into secondary contact after the last glacial maximum and that they are an evolutionary example of divergence maintained by climatic selection despite recurrent gene flow. |
