Vegetazione e paesaggio vegetale della dorsale del Monte San Vicino (Appennino centrale)
No full textThe vegetation and plant landscape of Monte San Vicino’s mountain group (Central Apennines). Here is presented a phytosociological study of the
vegetation and the plant landscape of the mountain group of Monte San Vicino. The vegetational typologies have been analysed through the correlation
with the lithological, geomorphological and climatic characteristics of the area. The mountain chain of Monte San Vicino is part of the Marche ridge
and in the north and north-west is bound by the Esino River Valley (Gola delle Rossa), in the south by the Potenza River Valley, in the east by the Laga
Basin and the outer Marche Bacin and in the west by the Camerino synclinorium. The highest peaks are found in the central part of the ridge (along
the anticline axis), and include Monte San Vicino as the highest of the ridge (1485 metres a.s.l.). The chain is mainly made up of calcareous lithotypes
belonging to the formations of the Umbria-Marche series while the turbidite lithology (various layers of sandstone and clay) from the Miocene,
surfaces along the eastern and southern edges of the ridge. The processing of temperature and precipitation data indicates a temperate oceanic
macrobioclimate, of the submediterranean variant, with two bioclimatic belts: hilly and montane.
The numerous vegetation typologies found in the territory belong to 19 different vegetation classes and are here presented on the basis of their
physiognomic and structural characteristics. The following new associations have been described: Hieracio racemosi-Fagetum sylvaticae, Cyclamino
hederifolii-Castaneetum sativae, Roso sempervirentis-Cercidetum siliquastri, Junipero communis-Ericetum arboreae, Rhamnetum infectorii-fallacis,
Digitalidi micranthae-Peucedanetum verticillaris, Ranunculo lanuginosi-Aconitetum neapolitani, Geranio sanguinei-Paeonietum villosae, Hieracio
racemosi-Luzuletum sylvaticae, Festuco circummediterraneae-Arrhenatheretum elatioris and Saturejo montanae-Cistetum eriocephali. To these can
be added numerous newly defined subassociations and variants of existing syntaxa. Furthermore, the individualization of the dynamic relationships
between the different plant associations found has allowed the reconstruction of the vegetation series. The integration of these series results in the
main landscape units present in the mountain group of San Vicino. The geosigmetum of the montane bioclimatic belt is represented by the basophilous
microseries of Sesleria apennina (Carici humilis-Seslerieto apenninae sigmetum) while the submontane belt of the ridge is represented by the
following series: the climatophilous, basophilous series of Fagus sylvatica on Calcare Massiccio and Maiolica (Lathyro veneti-Fageto sylvaticae
sigmetum) and the climatophilous subacidophilous one of Fagus sylvatica on Calcari diasprini (Hieracio racemosi-Fageto sylvaticae sigmetum).
In the high-hilly bioclimatic belt of the ridge the geosigmetum is represented by two climatophilous series: the basophilous series of Ostrya carpinifolia
(Scutellario columnae-Ostryeto carpinifoliae sigmetum) on the Maiolica, that in warmer slopes is replaced by the edaphoxerophilous series of
Quercus ilex (Cephalanthero-Querceto ilicis sigmetum), and the neutro-basophilous series of Quercus cerris (Aceri obtusati-Querceto cerridis sigmetum)
on the Marne a Fucoidi, on the Rosso Ammonitico and on the Calcari diasprini substrata.
Along the slopes belonging to the hilly bioclimatic belt, featuring a more significant mediterranean influence, are present two sub-mediterranean
climatophilous series: the basophilous of Ostrya carpinifolia (Asparago acutifolii-Ostryeto carpinifoliae sigmetum) and the neutro-basophilous of
Quercus cerris (Lonicero xylostei-Querceto cerridis loniceretosum etruscae sigmetum), and two edaphoxerophilous series: of Quercus ilex (Fraxino
orni-Querceto ilicis sigmetum) and of Quercus pubescens (Roso sempervirentis-Querceto pubescentis cotinetosum coggygriae sigmetum).
The geosigmetum of the hilly bioclimatic belt of the edges of the ridge characterised by terrigenous lithotypes (sandy-arenaceous substrata, sandy
colluviums, and sandy-lime colluviums) is made up of the following series: the edaphoxerophilous neutro-basophilous one of Quercus pubescens
(Peucedano cervariae-Querceto pubescentis ruscetosum aculeati sigmetum), the climatophilous subacidophilous one of Quercus cerris (Aceri obtusati-
Querceto cerridis ericetosum arboreae sigmetum), the edaphomesophilous one of Castanea sativa (Cyclamino hederifolii-Castaneeto sativae sigmetum)
and the edaphomesophilous one of Ostrya carpinifolia (Scutellario columnae-Ostryeto carpinifoliae prunetosum avium sigmetum).
On the gravely-sandy alluvial terraces is present the climatophilous neutro-basophilous series of Quercus pubescens (Peucedano cervariae-Querceto
pubescentis sigmetum)
Primi risultati sulla diversità floristica negli "anelli delle fate" in un settore dell'Appennino calcareo umbro-marchigiano (Appennino centrale)
No full textNew records for the Laga Mountains (Marche, Abruzzo, Lazio) and the central Apennines
No full textThis study includes 47 species collected between 1980 and 2012, most of them not previously reported for the Laga
Mountains. These include a number of species that are rare or are of particular phytogeographical interest, with their
presence hereby confirmed. In particular, the survey includes one new species for the central Apennines (Aconitum variegatum
subsp. variegatum), seven for Marche (Alchemilla exigua, Alchemilla marsica, Alchemilla sinuata, Alchemilla
undulata, Alchemilla versipila, Equisetum variegatum, Juncus articus), two for Abruzzo (Aconitum variegatum subsp.
variegatum, Alchemilla incisa), and one for Lazio (Veronica alpina). The presence in the central Apennines of Oxytropis
pilosa subsp. pilosa is also confirmed; although it has already been reported in several studies, it has been neglected in
recent floras. In agreement with previous scientific contributions, the present study confirms the considerable biogeographical
interest of the area due to the presence of species with an Arctic-Alpine distribution and/or of European orophytes,
as well as species that are endemic to the mountain range of the Laga Mountains, which represents the southern
limit of their distribution along the whole Apennine range
Effetti della colonizzazione di Brachypodium rupestre (Host) Roemer et Scultes sulla diversità di alcune fitocenosi erbacee dell'Appennino centrale
No full textEffects of Brachypodium rupestre (Host) Roemer et Schultes colonization on plant communities biodiversity in central Apennine. The impact of
Brachypodium rupestre colonization on grassland communities in different sites of the central Apennines was analyzed by phytosociological and ecophysiological
methods. Study areas were localized at the supratemperate and mesotemperate bioclimatic belts, on limestone, marly-limestone and
marly-sandy substrata. The authors observed a significant spatio-temporal reduction of number of species in Bromus erectus grasslands and Agropyron
repens old-fields due to the Brachypodium rupestre colonization process. Its propagation patterns and the impacts on plant communities biodiversity
are similar in the investigated areas, indipendently from the substrata type and the bioclimatic belt
