- Abstract
- We screened six populations of the clonal forest floor moss Plagiomnium affine
from forests of different ages for genetic variation at 23 allozyme loci. Samples
consisting of two adjacent, unconnected shoots were taken at regular intervals
along one transect from each population. Transect lengths varied from
22 to 52 m, depending on the size of the local populations. From a sample of
602 shoots, we detected a total of 16 haplotypes, of which two were widespread
and 12 were unique to single populations. Allelic variation, as measured
by allelic richness and Nei’s allelic diversity (HS), was significantly correlated
with forest age, when calculated at the ramet level,... (More) - We screened six populations of the clonal forest floor moss Plagiomnium affine

with forest age, when calculated at the ramet level, and nearly so when
calculated at the genet level. Widespread haplotypes dominated the younger
forest stands, whereas local haplotypes had a higher abundance in older forest
stands. Together, these results indicate that populations are subject to continuous
recruitment and that genetic variation accumulates as the forest ages. (Less)
