Abstract: [Photosynthetic activity in X. mawsonii was exceptionally high for Antarctic lichens and highly adapted to strong irradiance, and has a short reactivation phase. "Recovery of activity by absorbing water vapour from air, though practically possible, seems to be of ecological importance only under snow at subzero temperatures."
