Lichen Colonization and Recolonization of Two Recently Deglaciated Zones in the Maritime Antarctic
Abstract The stages of vegetation development close to two glacier fronts on two of the South Shetland Islands (Livingston and Robert) within the Maritime Antarctic were studied with special reference to saxicolous lichens. A lichenometric study of the crustose lichen Caloplaca sublobulata was carri...
