Aggiornamento dei subpopolamenti relitti di Petagnaea gussonei (Sprengel) Rauschert (Apiaceae) nell'area dei Monti Nebrodi (Sicilia nord-orientale)

Risultato della ricerca: Articlepeer review


In this paper authors point out some new unpublished sites of Petagnaea gussonei (Apiaceae), paleoendemic witha very narrow distribution in NebrodiMountains, also included in Bioitaly checklist of protected plants (CouncilDirective 92/43/EEC). For the same biotopes (located in Ucria, Tortorici, Longi, Galati Mamertino and S. Salvatore di Fitalia) they provide information and data concerning ecology, floristic, phytosociological and conservationstatus of subpopulations, together with a discussion of main threats.Moreover, they show an updated geographical distribution of the species, with the twenty recorded sites, also underlying the need for a suitable conservation in order to contain any regression of this macroendemism of theMediterranean area.
