Abstract: | The genetic structure, diversity and phylogeography of the moss species Campylopus oerstedianus in Europe was studied, based on the ITS region of the nrDNA of nine selected European populations. Although this species
is only known in sterile stage, long-distance dispersal and gene flow among populations seem to be present within Europe.
High levels of genetic differentiation between the investigated Greek population and the western European populations indicate
a long lasting isolation.
The populations from France and Switzerland root together and supposedly have a common origin. From the French populations,
the one from the Pyrenees is the most basal one and the populations in the Massif Central and the Vosges Mts can be derived
from it. This indicates relatively recent dispersal of the species from the Mediterranean to the north, in spite of the lack
of sporophytes and the fact that the type of the dispersed propagules and their vectors are not obvious. |
