Classification and phytogeographical differentiation of broad-leaved ravine forests in southeastern Europe / Petra Kosir in Journal of Vegetation Science, vol. 19, n°3 (Année 2008)

Average Pignatti indicator values for releves of each subcluster were subjected to PCA to show ecological relationships among the clusters. The spectra of geoelements and sociological species groups of individual subclusters were calculated to show phytogeographical and sociological relationships between them. The diagnostic species combination was calculated by a fidelity measure (φ-coefficient) and presented in a synoptic table. Results: Broad-leaved ravine forests in southeastern Europe form a separate group within the European broad-leaved ravine forests. They are well differentiated by the species with a southeast European distribution, as well as by many other species that reflect their different ecological affinities. Conclusions: The phytosociological and phytogeographical relationships between the Apennines and the Balkan peninsula that have already been recognized for other vegetation types have been confirmed for broad-leaved ravine forests. According to the numerical analysis, two suballiances of broad-leaved ravine forests in southeastern Europe are proposed, both belonging to the alliance Tilio-Acerion. an amphi-Adriatic xerothermo-philous suballiance Ostryo-Tilienion platyphylli suball. nova and a mesophilous suballiance Lamio orvalae-Acerenion suball. nova, the latter appearing only on the Balkan Peninsula."

Nomenclature and syntaxonomic notes on some high-rank syntaxa of the European grassland vegetation / Romeo Di Pietro in Lazaroa, vol. 36 (Année 2015)

Public [article]  inLazaroa > vol. 36 (Année 2015) . - pp. 79-106 Titre : Nomenclature and syntaxonomic notes on some high-rank syntaxa of the European grassland vegetation Type de document : texte imprimé Auteurs : Romeo Di Pietro, Auteur ; Jean-Paul Theurillat, Auteur ; Jorge Capelo, Auteur ; Federico Fernandez-Gonzales, Auteur ; Massimo Terzi, Auteur ; Andraz Carni, Auteur ; Ladislav Mucina, Auteur Année de publication : 2015 Article en page(s) : pp. 79-106 Langues : Anglais (eng) Catégories : [habitats/milieux] 3 - Landes, fruticées et prairies [ZG] Europe Mots-clés : phytosociologie  nomenclature  syntaxonomie Résumé : "We present descriptions of a new order (Ranunculo cortusifolii-Geranietalia reuteri)and of a new alliance (Stachyo lusitanicae-Cheirolophion sempervirentis) for the herbaceous fringe communities of Macaronesia and of the southwestern Iberian Peninsula, respectively. A new alliance, the Polygalo mediterraneae-Bromion erecti (mesophilous post-cultural grasslands), was introduced for the Peninsular Italy. We further validate and typify the Armerietalia rumelicae (perennial grasslands supported by nutrient-poor on siliceous bedrocks at altitudes characterized by the submediterranean climate of central-southern Balkan Peninsula), the Securigero-Dasypyrion villosae (lawn and fallow-land tall-grass annual vegetation of Italy), and the Cirsio vallis-demoni-Nardion (acidophilous grasslands on siliceous substrates of the Southern Italy). Nomenclatural issues (validity, legitimacy, synonymy, formal corrections) have been discussed and clarified for the following names: Brachypodio-Brometalia, Bromo pannonici-Festucion csikhegyensis, Corynephoro-Plantaginion radicatae, Heleochloion, Hieracio-Plantaginion radicatae, Nardetea strictae, Nardetalia strictae, Nardo-Callunetea, Nardo-Galion saxatilis, Oligo-Bromion, Paspalo-Heleochloetalia, Plantagini-Corynephorion and Scorzoneret alia villosae."
