DIVERSITY AND SIMILARITY OF LICHEN FLORAS OF COUNTRIES ALONG A SOUTH-NORTH GRADIENT FROM ITALY TO GREENLAND
Species diversities and similarities of lichen floras from Italy via Austria, Germany, Denmark, Finland, Sweden and Norway to Greenland are compared for the complete floras and separately for bark, wood, rock and soil, the latter two also for acidic and calcareous. Lichen species diversity declines...
