Phytosociological study of beech and beech-mixed woods in Monti Sibillini National Park (central Apennines, Italy)

The results of a phytosociological survey of the woods mainly growing on limestones in the Southern part of the Marches Region (Central Italy), that is part of the Monti Sibillini National Park, are here presented. This area is characterized by a temperate climate (upper mesotemperate and lower/upper supratemperate bioclimatic belts). In order to study the vegetation, 173 phytosociological relevés were carried out through the Braun-Blanquet methodology. All the data obtained were submitted to multivariate analysis. The phytosociological analysis is characterized in nine associations, whereof three are of new description (Lathyro veneti-Fagetum sylvaticae hieracietosum murorum, Cardamino kitaibelii-Fagetum sylvaticae corallorhizetosum trifidae and Cardamino kitaibelii-Fagetum sylvaticae anemonetosum nemorosae)

La vegetazione forestale dei substrati arenacei della Val d’Aso (Marche, Italia centrale).

Results of a phytosociological study on the wood on the sandstone bedrock are here presented. The studied area is located in the southern part of Marche Region, Ascoli Piceno Province, under the influence of temperate climate (lower/higher mesotemperate and lower supratemperate bioclimatic belts). The vegetation study has been performed throught 119 phytosociological relevés. All data were submitted to multivariate statistical analysis. The phytosociology analysis has permitted to characterize 6 associations, whereof 2 news: Erico arboreae-Quercetum pubescentis ericetosum arboreae and Hieracio murori-Ostryetum carpinifoliae hieracietosummurori. Chorological and synecological datas were described in the paper, compared to the corresponding associations of the limestones bedrock of the neighbouring area

An updated checklist of the vascular flora native to Italy

An updated inventory of the native vascular flora of Italy, providing details on the occurrence at regional level, is presented. The checklist includes 8195 taxa (6417 species and 1778 subspecies), distributed in 1092 genera and 152 families; 23 taxa are lycophytes, 108 ferns and fern allies, 30 gymnosperms and 8034 angiosperms. The taxa currently occurring in Italy are 7483, while 568 taxa have not been confirmed in recent times, 99 are doubtfully occurring in the country and 19 are data deficient. Out of the 568 not confirmed taxa, 26 are considered extinct or possibly extinct

Notulae to the Italian native vascular flora: 11.

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions. A new combination in the genus Pilosella is proposed. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1

Studio fitosociologico della vegetazione delle praterie montane dell’Appennino maceratese

L’analisi fitosociologica effettuata, pur essendo ulteriormente perfettibile, ha contribuito ad un ulteriore avanzamento del quadro conoscitivo della vegetazione pascoliva del Piano Bioclimatico supratemperato delle dorsali dell’Appennino Umbro-Marchigiano e ha permesso di ottenere dati correlabili tra loro, con i quali è stato possibile effettuare delle ipotesi sui modelli di distribuzione spaziale e temporale di queste comunità. Si tratta naturalmente di ipotesi di carattere generale e descrittivo, che dovranno essere in seguito maggiormente approfondite e verificate con dati di tipo quantitativo. Questo studio della vegetazione è stato in effetti effettuato con lo scopo di fornire un supporto chiaro ed esaustivo, che permettesse di affrontare in futuro lo sviluppo di altre analisi (storiche, ecologiche, produttive, ecc.) riguardanti l’ecosistema di prateria di questo importante territorio montuoso
