EFFECTS OF SOLAR UV-B RADIATION IN THE ACCUMULATION OF RHIZOCARPIC ACID IN A LICHEN SPECIES FROM ALPINE ZONES OF CHILE

In the lichen Acarospora schleicheri collected in altitudinal gradients at 18°S, 19°S, and 33°S in alpine zones of Chile, the concentrations of rhizocarpic acid were determined and compared. Significant increments in the accumulation of rhizocarpic acid were observed at the highest altitudes and the...
