In the present study, we investigated a wind-pollinated woody species of Changbai Mountain of northeastern China, namely, Betula ermanii Cham. This woody species B. ermanii is not only a dominant species in subalpine forest (SF), but it also occurs in the alpine tundra (AT) regions. This attribute indicates that it may play important roles in the two contrast habitats. In order to evaluate the influences of different habitats on differentiation in B. ermanii, we assessed the genetic and epigenetic population structure in selected populations from two contrasting habitats by using amplified fragment length polymorphism (AFLP) and methylation-sensitive AFLP techniques. According to our results, the AT group not only exhibits higher genetic and epigenetic diversity than the SF group but also shows greater population genetic and epigenetic differentiation. In addition, the analysis of cytosine methylation levels also revealed that the AT group exhibits higher degrees of genome methylation than the SF group. Taken together, our results indicate that populations from two contrasting habitats show significantly different genetic and epigenetic population structures. Along with other potential explanations, these findings suggest that environmental conditions could play an important role in facilitating adaptive evolution in B. ermanii.
