The impact of winter flooding with saline water on foliar carbon uptake and the volatile fraction of leaves and fruits of lemon (Citrus limon) trees
2012
We investigated the consequences of recurrent winter flooding with saline water on a lemon (Citrus × limon (L.) Burm.f.) orchard, focussing on photosynthesis limitations and emission of secondary metabolites (isoprenoids) from leaves and fruits. Measurements were carried out immediately after flooding (December), at the end of winter (April) and after a dry summer in which plants were irrigated with optimal quality water (September). Photosynthesis was negatively affected by flooding. The effect was still visible at the end of winter, whereas the photosynthetic rate was fully recovered after summer, indicating an unexpected resilience capacity of flooded plants. Photosynthesis inhibition by…

Modeling the influence of alternative forest management scenarios on wood production in the mediterranenan region. The MiMoSe approach.
2014
Ecosystem services (ES) are defined as the benefits that human obtain from ecosystems. Forest ecosystems provide many essential goods and services, such as flood and landslide control, erosion prevention and maintenance of soil fertility, water and air quality, biodiversity, wildlife habitat, recreational space for humans and aesthetic appreciation of natural landscapes, wood for fuel, construction and fibre, biomass for energy, and non-timber forest products. The quality and quantity of these goods and services are influenced by forest management, especially in the Mediterranean area where the forest has been exploited for a long time. In this study, we propose a method (MiMoSe- Multiscale…
DRIFTS Sensor: Soil Carbon Validation at Large Scale (Pantelleria, Italy)
2013
A fast and accurate measurement of soil carbon is needed in current scientific issues. Today there are many sensors suitable for these purposes, but choosing the appropriate sensor depends on the spatial scale at which the studies are conducted. There are few detailed studies that validate these types of measures allowing their immediate use. Here it is validated the quick use of a sensor in execution at Pantelleria, chosen for size, use and variability of the parameter measured, to give an operational tool for carbon stocks studies. The DRIFT sensor used here has been validated in the first 60 cm of the soil of the whole island, and it has shown predictivity higher than 90%.
Agricultural land abandonment in Mediterranean environment provides ecosystem services via soil carbon sequestration
2016
Abandonment of agricultural land leads to several consequences for ecosystem functions. Agricultural abandonment may be a significant and low cost strategy for carbon sequestration and mitigation of anthropogenic CO2 emissions due to the vegetation recovery and increase in soil organic matter. The aim of this study was to: (i) estimate the influence of different Soil Regions (areas characterized by a typical climate and parent material association) and Bioclimates (zones with homogeneous climatic regions and thermotype indices) on soil organic carbon (SOC) dynamics after agricultural land abandonment; and (ii) to analyse the efficiency of the agri-environment policy (agri-environment measur…

È possibile tracciare un bilancio sull’eucalitticoltura in Sicilia e sulle sue prospettive?
2017
La storia dell’eucalitticoltura in Sicilia è ormai una storia di mezzo secolo. La diffusione dell’eucalitticoltura in Sicilia e nelle regioni meridionali in genere ha corrisposto alla diffusione di un modello nuovo per queste realtà. Diversi errori sono stati compiuti soprattutto con riferimento alle scelte tecniche compiute a posteriori (scelta delle stazioni, assenza di cure colturali, utilizzazioni improprie). Un rinnovato interesse per questi popolamenti è derivato dalle opportunità offerte per l’utilizzazione energetica. Tuttavia anche questo approccio mostra i suoi limiti legati alla necessità di ricorrere a grossi volumi di legname e ad un utilizzo delle risorse legnose forestali sic…
Storia dell’eucalitticoltura in Sicilia.
2013
Eucalyptus, Italia, paesaggio, rimboschimento, selvicoltura, storia Gli eucalitti vantano una lunga storia nel nostro paese; erano già presenti infatti in Campania all’inizio dell’800 nel giardino botanico annesso alla regia di Caserta e fu proprio l’Hortus Camaldulensis a dare il nome all’Eucalyptus camaldulensis una delle specie più diffuse in Italia e nel Mondo. I primi impianti in Italia vanno fatti risalire al 1869 ad opera dei monaci della “Abbazia delle Tre Fontane” a Roma. Le ragioni iniziali della diffusione degli eucalitti vanno legate alla convinzione che potessero rendere salubre l’aria e contrastare la diffusione della malaria, effetto dovuto alla capacità dell’eucalipto di pro…
Forest planning across Europe: the spatial scale, tools, and inter-sectoral integration in land-use planning
2014
New approaches to forest planning are needed to support the transition of European forests to sustainable management. The aim of this study is to review forest planning systems already in place throughout Europe by exploring a set of case-study countries reflecting the main silvicultural schools of Western Europe, including Belgium, Finland, France, Italy, Portugal, and Slovenia. A literature review and case-study data were used to assess the scale factors (vertical logic) as well as the relationships between forest planning and other environmental6 land-use planning sectors (horizontal logic). The influence of EU policy on the development of forest planning is also discussed. As assessed u…
Forest types for biodiversity assessment at regional level: the case study of Sicily (Italy)
2007
Within Europe the question of plant coenosis is attracting growing interest. The quality and quantity of collected information on forest resources at a global level largely depends on the capacity to collect and analyse data at national and sub-national scale in a way compatible with those at global or continental levels. In Italy the acceptance of all the international agreements and protocols on the protection of the environment and management of natural resources, requires a standardization of collected information and statistics, with the aim to produce homogeneous and integrative data at global level. This need is reflected in the following points: (1) the adoption of a classification …
