The primary grasslands of the northern Apennine summits (N-Italy): a phytosociological and ecological survey
This paper provides a comprehensive phytosociological survey on the alpine grasslands occurring on the northern Apennine summits (N-Italy). The study area represents a crucial phytogeographic joint between the Alps and the Apennines and its summit grassland vegetation was only partially document-ed...
