Abstract: [Microsatellite study of Lobaria pulmonaria in spruce forests in the Swiss Jura Mountains. "We found evidence for multiple independent immigrations into demes located in burnt and logged areas. The spatial autocorrelation was predominantly attributed to clonal dispersal of vegetative propagules. This pattern may indicate low dispersal ranges of clonal propagules, but random dispersal of sexual ascospores. Genetic diversity was highest in logged demes, and lowest in burnt demes." Disturbance may not impact genetic diversity for extended time periods.]
