Phytosociological study of the acidophilous deciduous oak woods with Ilex aquifolium of Sicily

2009

We present here a phytosociological study with ecological considerations of some formations with a prevalence of Quercus pubescens s.l. and Ilex aquifolium that occur on siliceous ground in the Madonie and Peloritani Mountains of Sicily. On the basis of this study, these formations have been attributed to two new associations: Ilici aquifolii-Quercetum leptobalani and Conopodio capillifolii-Quercetum congestae, within the order Quercetalia pubescenti- petraeae, which is already represented by other associations in Sicily.

Protection and conservation of the manna ash landscape in Sicily

2017

Known as manna ashes, some local varieties of Fraxinus ornus L. and F. angustifolia Vahl (Oleaceae) are cultivated for extracting the manna, a product rich in mannose which is useful under both pharmaceutical and nutraceutical aspects. As wild plants in Sicily these ashes participate in diversifying evergreen and deciduous oak woods as well as other forest communities at the watercourse borders, together with several species of Salix, Populus and Ulmus, particularly in the hills. Cultivation of manna dates back to ancient times in Sicily and elsewhere and ash groves were increasingly spread up to the half of last century. Then, the culture had a progressive decline due to the abandonment of…

L'iconografia della Storia Naturale delle Madonie: consistenza e sviluppo

Orophilous aspects of relictual vegetation of the class Rhamno-Prunetea localizated on the Madonie Mountains (NW Sicily).

2009

The deciduos shrubby mantle coenoses referred to the class Rhamno catharticae-Prunetea spinosae are secondary communities - sometimes permanent - localized in the climactical dominion of the forests of Querco-Fagetea and Quercetea ilicis or the riparian woodlands of Salici-Populetea nigrae. These communities are widespread from the Eurosiberian to the Mediterranean region, and are linked to rich nutrient humic soils, rocky slopes and screes (1). In Italy, the class Rhamno-Prunetea is represented by the alliances Cytision sessilifolii, Berberidion vulgaris, Pruno-Rubion ulmifolii and Salici-Viburnion opali, the latter showing hygrophilous character (2). As concerns the mountain and submounta…

The great landslide at Portella Colla (Madonie, Sicily)

1996

The South Western area of the Madonie Mountains is affected by large landslides; the major one developed starting from Portella Colla down to the Imera Settentrionale river, for a maximum length of about 6.2 km in a NE-SW direction. The study of the landslide, with the aim of reconstructing the geological, geomorphological and evolutionary aspects, has been carried out using integrated methodologies, including some geophysical investigations (in particular geoelectrical prospecting). The landslide is complex and characterized by superficial and deep gravitational deformations. The movement began in the Upper Pliocene and it is still active. The origin and evolution of the landslide are link…

GEOCHEMICAL AND GEOPHYSICAL RESEARCH AIMED AT CHARACTERIZING THE HYDRO-GEOLOGICAL STRUCTURES OF A KARST FORMATION

2009

Geochemical and geophysical research was effected in an area between the Madonia mountain range and the coast around the Rock of Cefalù, at the base of which there are a number of large-sized springs. The aim of the study was to reconstruct the buried hydro-geological structures that carry the waters from the Madonia Mountains to the areas along the coast where they surface. The Madonia Mountains are prevalently made up of carbonatic formations and terrigenous deposits of the Numidian Flysch. Outcrops of the Cozzo Terravecchia formation are also present, as are Messinian evaporitic deposits and recent detritic deposits of alluvial and marine origin. The Karst processes that develop in the l…
