Basic information of Castanopsis sclerophylla populations and the parameters of genetic diversity in the present study.

A: habitat size (hm2); D: distance to the nearest landmass (km); N: estimated or real population sizes; NS: sample size; NA: number of alleles per locus; AR: allelic richness, based on minimal sample size of 5 individuals, post-fragmentation cohorts with only 1 individual were excluded for calculation; HO: observed heterozygosity; HE: expected heterozygosity; HcpDNA: Nei's gene diversity based on cpDNA microsatellite data. Values of pre-and post-fragmentation cohorts are shown in parenthesis.NA: not available.
