Influence of Nothofagus bark pH on the lichen and bryophytes richness, Central Chile

The influence of the pH of the bark of two tree species belonging at Nothofagus genus on the lichen and bryophyte richness was studied. The tree species considered for this study were: N. dombeyi and N. macracarpa situated in two pre-Andean localities; one in the "Radal Siete Tazas" Nation...
