20.500.12556/DiRROS-25588 Unveiling unique endemic associations: a contribution to the knowledge of chasmophytic vegetation on the Sorrento Peninsula and Picentini Mountains Sorrento Peninsula, together with an outpost at the top of the Picentini Mountains, is rich in local endemics and has been well studied from a taxonomical perspective. The vegetation is instead poorly known, particularly the plant assemblages of rock cliffs. In this paper, we present the phytosociological insights on cliff-dwelling communities of rocky ranges in the top of Sorrento Peninsula (600-1800 m a.s.l.). We carried out 28 relevés (8 already published) and conducted multivariate analyses to classify the vegetation. We analysed the bioclimatic context of the relevés with Rivas-Martínez indexes and carried out a comparison with other rock vegetation from the Central Mediterranean. We found three clusters that we classified into 2 associations, one of which is further divided into two sub-associations (Globulario neapolitanae-Loniceretum stabianae typicum Fanelli et al. 2020; Globulario neapolitanae-Loniceretum stabianae globularietosum neapolitanae subass. nova; Diantho virginei-Seselietum polyphylli ass. nova). We refer this vegetation to a new alliance, Lonicerion stabianae all. nova, distinguished from the other rock vegetation of the Central Mediterranean because develops in an intermediate range between the mediterranean, temperate and weakly continental climate. Sorrento Peninsula and the cliffs at the top of Picentini Mountains are characterised by endemic cliff vegetation, rich in exclusive taxa. We suggest that it represents a distinct phytogeographical sector in the context of the Italian Peninsula. Polotok Sorrento in gorovje Picentini imata bogato endemično floro, ki je bila taksonomsko tudi dobro preučena, njuna vegetacija, predvsem vegetacija klifov, pa je slabo poznana. V članku predstavljamo fitocenološki pogled na rastlinske združbe klifov s teh dveh območij. Naredili smo 28 vegetacijskih popisov (8 je bilo že objavljenih) in jih klasificirali z multivariatnimi metodami. Bioklimatske značilnosti smo analizirali z indeksi po Rivas-Martínezu in primerjali z naskalno vegetacijo srednjega Sredozemlja. Ugotovili smo tri klastre in jih uvrstili v eno asociacijo in dve subasociaciji: Globulario neapolitanae-Loniceretum stabianaetypicum; Globulario neapolitanae-Loniceretum stabianae globularietosum neapolitanaesubass. nova; in Diantho virginei-Seselietum polyphylli ass. nova. To vegetacijo uvrščamo v novo zvezo Lonicerion stabianae all. nova, ki jo označuje vmesna sredozemska, zmerna in slabo kontinentalna klima. Endemična vegetacija klifov v teh območjih nakazuje poseben fitogeografski sektor na italijanskem polotoku. casmophytic vegetation Mediterranean phytogeography rock vegetation Southern Italy syntaxonomy hazmofitska vegetacija sredozemski fitogeografija naskalna vegetacija južna Italija sintaksonomija true false true Angleški jezik Slovenski jezik Imetniki avtorskih pravic na prispevkih so avtorji Neznano 2026-01-23 20:22:52 2026-01-23 20:22:53 2026-02-20 14:44:39 0000-00-00 00:00:00 2025 0 0 Raziskovalni podatki, na katerih temelji objava, bodo na voljo na EVA database in/ali na razumno zahtevo pri avtorju str. 1-14 št. 1 letn. 24 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-07-15 581.9:551.586(450.7) 1581-4661 10.3986/hacq-2025-0003 230709507 https://ojs.zrc-sazu.si/hacquetia/article/view/13712/12085 1 ebff90c8-f890-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38772 _HACQUETIA_24-1_2025_1_La+Montagna+et+al.pdf _HACQUETIA_24-1_2025_1_La+Montagna+et+al.pdf 1 ECBBEF3C6D705C64F3DD6887AFDF74F4 6a8b7f7fb6ae743ab3bfc846bec7b0234242dd3b8bfce90723d77dc29894a066 3481dec6-f892-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38773 Znanstvenoraziskovalni center Slovenske akademije znanosti in umetnosti Hacquetia 0 0 0
