Random amplified polymorphic DNA (RAPD) markers were characterized for 25 specimens of Usnea filipendula to evaluate the genetic diversity of populations reinvading formerly uninhabited regions in Northrhine-Westphalia due to decreasing sulfur dioxide levels. With six 10-mer randomly amplified polymorphic DNA (RAPD) primers, a 66 character by 25 specimens matrix was generated. Phenetic analysis (UPGMA) showed no obvious groupings. The reinvading populations are distributed over the phenogram and are not genetically closely related. The results suggest that the reinvading populations of this usually sterile species are derived from different sources and do not consist of a particular clone capable of re-entering the area.
