Effects of traditional coppice practices and microsite conditions on tree health in a European beech forest at its southernmost range
2016
Abstract: European beech (Fagus sylvatica) grows at the southern limit of its range in the mountain-Mediterranean vegetation belt up to the timberline. The southernmost beech forests of Sicily (southern Italy) show peculiar ecological, structural and silvicultural characteristics, growing in fragmented and isolated stands near the timberline and in topographically marginal unfavorable habitats. Past silvicultural practices increased the heterogeneity of stand structure at these sites. We compared stand structural characteristics and tree health in coppice-cut and control beech stands with respect to the local topographic gradient (bottom, slope and ridge) and canopy cover (clearing/border v…

Notes on the karyology, genetics and ecology of Genista sect. Voglera in Sicily
2012
To investigate the biosystematic and genetic relationships among Sicilian species of Genista sect. Voglera, four populations of three species, Genista aristata C. Presl, Genista cupanii Guss., and Genista madoniensis Raimondo, have been studied. Genista madoniensis is tetraploid, with a chromosome number of 2n = 48, as are the other two species. An isozyme study showed that G. madoniensis is taxonomically closer to G. aristata than to G. cupanii, the latter possessing four unique alleles. The results are discussed in the context of the ecological characteristics of each species.

Mattei is an endemic species of Sicily seriously threatened with extinction. Its natural population consists of individuals, occurring in a narrow area within the territory of the Madonie Regional Park. A. nebrodensis has been subject to specific conservation measures implemented by the University of Palermo, the Park Authority and the Regional Department of Forests of the Sicilian Region and other local partners for o…
IL DINAMISMO DELLA VEGETAZIONE IN UNA MONTAGNA RAPPRESENTATIVA DELLA SICILIA: LE MADONIE
2013
RÉSUMÉ On décrit les séries de végétation du massif des Madonie en Sicile. Ici sont développées trois séries dynamiques de végétation, à savoir: la série mesophyle basiphyle du hêtre (Fagus sylvatica) , la série océanique acidophyle méridionale du hêtre (Fagus sylvatica) et la série orophyle acidophyle du rouvre méridionale (Quercus petraea subsp. austrotyrrhenica).

New records of Malus crescimannoi (Rosaceae) in Sicily
2016
New findings for Malus crescimmanoi, originally known from the mountain area near Floresta (Nebrodi Mts.). The new sites fall in Madonie Mts., where the species is found at the edge of Quercus petraea (Matt.) Liebl. and Fagus sylvatica woods, growing on quartzarenitic substratum at 1200-1800 m of elevation. These new localities are placed at the south-western limit of Fagus sylvatica distribution area, on both north-facing [Contrada Sempria (Castelbuono) and slopes of Madonna dell’Alto (Castellana Sicula)], and south-facing slopes [Locality Prato (Polizzi Generosa)].
First record of Ribes uva-crispa L. (Grossulariaceae) from the Madonie Mts., a new species of the Sicilian flora.
2011
Abstract In this study, a first record of Ribes uva-crispa L. (Grossulariaceae) – a new species of the Sicilian flora – from the Madonie Mts. is reported. The autochthonous and relict new population of Ribes uva-crispa L. (Grossulariaceae) is found on Mount Carbonara (Madonie Mts., North-Central Sicily), which is several hundred kilometers away from the Central Apenninic and the South Mediterranean locations of its distribution range. R. uva-crispa shows a distribution similar to other taxa extending from the Euro-Asiatic area to the mountains of North Africa with disjunct populations on the main Sicilian reliefs (Madonie and Nebrodi Mts.), testifying ancient phytogeographical connections. …
Madonie Geopark - Calendario 2009
2009
Le Madonie costituiscono da oltre un secolo una delle aree più interessanti per la Geologia della Sicilia. I rilievi montuosi di questo territorio hanno registrato negli strati rocciosi l'evoluzione geologicha e biologica di un intervallo temporale di oltre 200 milioni di anni. Numerosi Geologi e Paleontologi hanno condotto in que'area ricerche fondamentali per comprendere l'origine non solo di questi rilievi, ma dell'intera catena montuosa che si estende dagli Appennini alle Maghrebidi del Nord Africa. La buona esposizione delle successioni rocciose, che offrono una inesauribile gamma di esempi per la didattica delle Scienze Geologiche , unitamente alla bellezza dei paesaggi, hanno fatto d…
