[Molecular ecology of Cryptocarya chinensis populations in different communities]

The amplified fragment length polymorphism (AFLP) method was used to analyze two populations of Cryptocarya chinensis, the succession climax species in lower subtropical broadleaved forest. The across two communities of evergreen broadleaved forest and mixed coniferous-broadleaved forest. The analysis of molecular variance (AMOVA) indicated that the genetic variation was mostly due to the difference within individuals of the population (89.55%), with high significant genetic variation (10.45%) due to the different communities. The microenvironment of different communities and population biological characteristics resulted in the genetic divergence.
