Spatial genetic structure in a Neolitsea sericea population (Lauraceae)
Neolitsea sericea (Bl.) Koidz. (Lauraceae) is a dioecious, insect-pollinated, and broad-leaved evergreen tree with bird-dispersed seeds. We used allozyme loci, F -statistics, and spatial autocorrelation statistics (Moran’s I ) to examine the changes in genetic structure among five age classes within...

(Bl.) Koidz. (Lauraceae) is a dioecious, insect-pollinated, and broad-leaved evergreen tree with bird-dispersed seeds. We used allozyme loci,
F
-statistics, and spatial autocorrelation statistics (Moran’s
I
) to examine the changes in genetic structure among five age classes within a study population (60 m × 100 m area) in southern Korea. No significant differences in expected heterozygosity were found among the age classes. The mean
F
-values averaged over loci were similar among age classes and showed overall conformance of heterozygosities with Hardy–Weinberg proportions. Differences in allelic frequencies among age classes were small (mean
G
ST
=0.012), and statistically significant only for one locus (
Pgd-2
). The mean Moran’s
I
-values for each of five age classes indicated essentially random spatial distribution. The homogeneity of genetic structure and genetic diversity among the five age classes may reflect the occurrence of similar reproductive events, year after year. The results may reflect the attractive red drupes of
N. sericea
in that they cause various frugivorous birds to disperse the seed long distances and independently, which in turn may help
N. sericea
maintain higher levels of genetic diversity within populations. |
