Intraspecific Variations of Morphology and Physiology of Temperate to Arctic Populations of Cetraria Nivalis
Abstract Five populations of the circumpolar Arctic-alpine lichen species Cetraria nivalis were sampled along a latitudinal gradient from the temperate to the Arctic climatic zone. The populations were compared with respect to their CO 2 exchange, water relations and morphology/anatomy. Provenances...
