Bryophyte vegetation of the fumaroles from some Mediterranean and Macaronesian territories
The results of a phytosociological investigation on the bryophyte communities, occurring in the fumaroles of Pantelleria (Sicily), Ischia and Pozzuoli (S Italy), Tenerife (Canary Islands), are given. It is a very peculiar vegetation linked to microclimatic hot-moist conditions of tropical type. The Mediterranean communities are included into the new class Campylopodetea vaporarii with one order (Campylopodetalia vaporarii) and one alliance (Campylopodion vaporarii); within this alliance the following associations are recognized: Campylopodetum vaporarii with the subassociations typicum and campylopodetosum pyriformis, Calymperetum erosi, Isopterygio teneri-Cyperetum polystachyi with the subassociations typicu , epipterygietosum tozeri and grimmietosum lisae. The association surveyed in the Macaronesian region is referred to Campylopodion piliferi, alliance belonging to the order Polytrichetalia piliferi of the class Ceratodonto-Polytrichetea piliferi; it is Campylopodetum polytrichoidis with two subassociations: dicranelletosum variae and campylopodetosum introflexi. Toevaluate the similarity among the relevés a multivariate numerical analysis has been performed.
