AFLP from two contrasting habitat types

We get these data from AFLP. In our study, we compare the genetic diversity and differentiation between two contrasting habitat types of Betula ermanii. Our results indicated that the two different type show different genetic structure. We presume that this species evolve under natural selection.本研究数据源自扩增片段长度多态性（Amplified Fragment Length Polymorphism, AFLP）。我们以岳桦（Betula ermanii）两种截然不同的生境类型为研究对象，比较了其遗传多样性与遗传分化水平。研究结果显示，两类生境下的岳桦种群呈现出不同的遗传结构。我们推测该物种是在自然选择作用下演化而来的。
