Climate Change and the Ecophysiological Response of Arctic Lichens
Abstract Under field conditions of optimal water hydration, lichen photosynthesis is primarily light-limited and nitrogen fixation is temperature-limited in both Peltigera canina and Stereocaulon tomentosum at Anaktuvuk Pass, Alaska. Thus, where duration of optimal hydration conditions remains uncha...
