Field measurements of CO 2 exchange were made with an infra-red gas analyser system on lichens at Bailey Peninsula, Wilkes Land, continental Antarctica. It has been demonstrated that Usnea sphacelata , a prominent element of the cryptogamic vegetation of this area, became photosynthetically active a...
