Primo rinvenimento di Juniperus sabina L. sul massiccio del Pollino, Italia meridionale

1992

Viene segnalata per la prima volta la presenza di Juniperus sabina L. sul massiccio del Pollino, dove la specie è stata rinvenuta in habitat rupicolo in due stazioni ricadenti rispettivamente in territorio calabrese e lucano. Le stazioni vengono caratterizzate dal punto di vista floristico ed ecologico.

The presence of Juniperus sabina L. an Eurasian element is recorded from southern Italy where it has been found in two sites on Mt. Pollino. In Italy this species was so far reported only from the Alps and a few localities of central Apennines. Therefore the finding on Mt. Pollino largely widens its distribution southwards in the Italian Peninsula. As regards Europe J. sabina reaches lower latitudes only in southern Spain. The Authors stress the phytogeographical significance of the sites which are characterized from the floristic and ecological viewpoint.Settore BIO/02 - Botanica Sistematica

Comparative high-resolution chemostratigraphy of the Bonarelli Level from the reference Bottaccione section (Umbria-Marche Apennines) and from an equ…

2006

The Bonarelli Level (BL) from the upper Cenomanian portion of the reference Bottaccione section (central Italy) is characterized by the presence of black shales containing high TOC concentrations (up to 17%) and amounts of CaCO3 near to zero. In the absence of carbonate and, consequently, of relative carbon- and oxygen-isotopic data, the elemental geochemistry revealed to be a very useful tool to obtain information about the palaeoclimatic and palaeoceanographic evolution of the Tethys Ocean during the OAE2. Based on several geochemical proxies (Rb, V, Ni, Cr, Si, Ba), the BL is interpreted as a high-productivity event driven by increasingly warm and humid climatic conditions promoting an a…

Hieracium hypochoeroides subsp. peracutisquamum (Asteraceae), a new taxon from Basilicata, (southern Italy)

2015

Hieracium hypochoeroides subsp. peracutisquamum, a new taxon endemic to Basilicata (southern Italy), is described and illustrated. It is confined to the carbonate rocks of Monte della Madonna di Viggiano (Lucanian Apennine, SW Basilicata). Information on its ecology and taxonomic relationships is provided.

The effects of post-orogenic extension on different scales: an example from the Apennine-Maghrebide fold-and-thrust belt, SW Sicily

2003

Many structures produced under one single deformation regime, namely extensional, contractional or strike-slip, exhibit remarkable geometrical analogies when analysed at different scales. By contrast, field examples that illustrate the scale effects on structures resulting from superimposed deformations, which were produced under different tectonic regimes, are rare. Yet the change from contraction to extension is known to occur often in the most thickened portions of the continental crust. The Apennine–Maghrebide fold-and-thrust belt of Sicily shows many examples of post-orogenic extensional deformations. Composite structures, resulting from late normal faults that offset folds and thrusts…

SELVICOLTURA ALPINA E SELVICOLTURA APPENNINICA: ELEMENTI DI CONTATTO E DI DIFFERENZIAZIONE

2009

Riassunto Il rapporto tra boschi e popolazioni locali sulle Alpi come sugli Appennini, seppur in momenti storici differenti, è stato caratterizzato dalla distruzione e sfruttamento intensivo, protrattisi fino alla metà del secolo scorso, cui hanno fatto seguito la ricostituzione sia mediante rimboschimenti sia con il miglioramento dei boschi esistenti. Partendo dai presupposti sui quali si è imperniata l’attività forestale che ha caratterizzato, nel corso degli ultimi cinquant’anni, l’approccio selvicolturale nei due contesti e da una puntuale e documentata analisi, nel lavoro vengono evidenziati gli elementi di differenziazione tra la selvicoltura naturalistica applicata in ambiente alpino…
