CPMAS 13C NMR Characterization of Leaves and Litters from the Reafforestated Area of Mustigarufi in Sicily (Italy)
2010
Reafforestation is generally based on the planting of exotic fast growing tree species suitable for adapting to even harsh environments. Once the introduced plants ameliorate soil conditions, they can be progressively replaced by au- tochthonous plant species. Reafforestation is applied worldwide. However, only few studies on the effect of reafforesta- tion on lands from Mediterranean regions are available. This paper reports the characterization by cross polarization 13C NMR spectroscopy of fresh leaves and superficial litters from a reafforestated area in central Sicily (Italy). NMR assign- ment is attempted. A differentiation among the molecular systems within leaves and litters is also …
Intervento di ripristino della copertura arborea su un'area del parco dell'Etna interessata da colata lavica recente.
1996
The planning and results of a reafforestation carried out on a private area occurring in the Etna Wildlife Reserve C zone are presented. The area consists of a terraced slope 70.000 square meters wide, made out of a lava flow part which dates back to 1983. At first were planted and seeded Astragalus siculus Biv. and Festuca circummediterranea Patzke, in order to set a pioneer vegetation cover; then were planted some aboreal species having a leading role in the physiognomical characterisation of the Etna landscape, like Betula aetnenis Raf., Pinus laricio Poiret, Populus tremula L. The success of the intervention is shown by the fairly quick penetration of 26 species coming from the neighbou…
Adaptive plasticity of blue tits(Parus caeruleus)and great tits(Parus major)breeding in natural and semi‐natural insular habitats
2004
The breeding performance and foraging of blue and great tits, and the abundance of arthropods living on the trees of an oak-wood and of a coniferous reafforestation were studied in Sicily, in order to: 1) compare breeding parameters in natural and semi-natural habitats within the same area; 2) estimate the degree of overlap in peak resource and peak demand of young tits, and the overlap of nestling diet of the two species in the two habitats. Both species had earlier laying dates, laid more eggs and raised more fledglings in the oakwood than in the reafforestation; they achieved the same fledging success within the same habitat type. These differences are probably due to the earlier and hig…
