Sammanfattning

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, 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.
