PLANT SUCCESSION ON SICILIAN TERRACES

2007

189 phytosociological relevés have been made in five areas of Sicily, three on volcanic substrates and two on limestones, to study plant community succession trends within abandoned terraced vineyards and cereal fields. Disturbance status and abandonment age was recorded for each sample plot. DCA of these relevés suggests that four are the most important factors driving succession, i.e. geological substrate, bioclimate, age of abandonment and disturbance. In most cases - if there are some dispersal centres near the old fields - undisturbed and less disturbed terraces evolve quite rapidly towards the local potential “climax” community. Different tren…

Additional insights on the ecology of the relic tree Zelkova sicula di Pasquale, Garfì et Quézel (Ulmaceae) after the finding of a new population

2011

Abstract In early autumn 2009 a new population of Zelkova sicula, a very threatened tree species endemic to Sicily, has been found some 17 km east from the first and unique population previously known. The abiotic (slope, rock and stone outcrop cover, environmental stress, etc.) and biotic (plant species composition, vegetation mean height, total cover, etc.) features of 30 plots selected within the two populations were investigated in order to contribute at clarifying the actual and potential eco-geographic range of this species. Data analysis showed that the floristic differences among the sampled plots mostly relate to the rather high micro-habitat amplitude of the target species and the…

Quando i corpi svelano lo spazio

2020

Living means transfiguring the place and loading it with meanings that transcend its pure objectivity, allowing our body to feel itself among "its things", close to itself. The path of "transfiguration" inherent in living interprets the complementarity between man and his environment and reveals the poetic capacity of architecture. Thus, it may be interesting to understand how the interaction between body and space can make us regain possession of the most problematic places, within a mental and transcendent dimension.

Effects of high pressure thermal treatments in oxygen and helium atmospheres on amorphous silicon dioxide and its radiation hardness

2009

The effects of thermal treatments at similar to 400 degrees C in oxygen or helium atmospheres at similar to 180 baron the radiation hardness of amorphous SiO(2) are studied. The generation efficiency of several point defects under gamma irradiation is compared to that of the untreated material. All the effects on point defects generation here observed can be explained in terms of changes in the precursor sites. In particular it has been observed that the thermal treatments can change the precursors sites of point defects both through temperature and pressure related processes, not depending on the atmosphere, and through oxygen related processes creating oxygen excess sites. The presence of…

In-situ observation of beta-ray induced UV optical absorption in a-SiO2: radiation darkening and room temperature recovery

2006

International audience; We studied the optical absorption in the 3.0-6.2 eV range induced in bulk amorphous SiO2 by beta-ray irradiation up to similar to 1 MGy at room temperature. The induced absorption was measured in situ both during irradiation and in the post irradiation time. Our data evidence E', center as the main defect induced by irradiation and the partial decay of their absorption band at about 5.8 eV after irradiation. A quantitative analysis of the time evolution of the induced absorption shows that the transmission recovery observed after irradiation is compatible with the reaction of radiation-induced defects with H-related (H-2, H2O) species diffusing in the amorphous matrix
