Abstract: 11 figures. [Study on King George Island, South Shetland Islands, on Usnea antarctica and other Antarctic species. "Our preliminary field data demonstrate that Antarctic lichen species from the same area have a very differing photosynthetic productivity." Opitma are low temperatures and moderate light, while very high water content reduces photosynthetic capacity.]
