Hierarchical analysis of molecular variance (AMOVA) of spatial genetic structure for the 14 populations of Zostera marina based on eight microsatellite loci.

The KJ populations sampled in 2005 (KJ05-S, KJ05-D) were excluded from this analysis since detectable temporal genetic variation was observed. The analyses were performed by grouping the geographic populations according to the respective regions (Jeju Island and South Sea; see Materials and Methods).
