Ecology of endolithic lichens colonizing granite in continental Antarctica
13 pages,tables statistics, figures and photos In this study, the symbiont cells of several endolithic lichens colonizing granite in continental Antarctica and the relationships they have with the abiotic environment were analyzed in situ, in order to characterize the microecosystems integrating the...
