Abstract: [Authors mention Rhizocarpon and Umbilicaria spp. for the study sites. "The degree of weathering on lichen-free and lichen-covered cobble surfaces is not initially distinguishable, but diverges sharply after c. 250 years, when lichen-covered surfaces experience significantly higher totals."]
