We studied forest monitoring data collected at permanent plots in Italy over the period 2000-2009 to identify the possible impact of nitrogen (N) deposition on soil chemistry, tree nutrition and growth. Average N throughfall (N-NO3 +N-NH4 ) ranged between 4 and 29 kg ha(-1)  yr(-1) , with Critical Loads (CLs) for nutrient N exceeded at several sites.(More)
Land Degradation (LD) is a complex phenomenon resulting in a progressive reduction in the capacity of providing ecosystem services (ES). Landscape transformations promoting an unsustainable use of land often reveal latent processes of LD. An evaluation carried out in respect to the different ecosystem services is nowadays regarded as the most appropriate(More)
Nitric oxide (NO) has emerged as an important cytotoxic and cytostatic effector for a number of pathogens, including viruses, bacteria, fungi, and parasites. When the microbicidal effect of NO occurs, the NO-mediated S-nitrosylation of cysteine containing proteins (e.g., cysteine proteases) appears to be a common and widespread mechanism. This overview(More)
Nitric oxide (NO) is a versatile regulatory molecule that affects enzymatic activity through chemical modification of reactive amino acid residues (e.g., Cys and Tyr) and by binding to metal centers. In the present study, the inhibitory effect of the NO-donors S-nitroso-glutathione (GSNO), (+/-)E-4-ethyl-2-[E-hydroxyimino]-5-nitro-3-hexenamide (NOR-3), and(More)
This study implements an exploratory data analysis of landscape metrics and a change detection analysis of land use and population density to assess landscape dynamics (1954-2008) in two physiographic zones (plain and hilly-mountain area) of Emilia Romagna, northern Italy. The two areas are characterized by different landscape types: a mixed urban-rural(More)
A diachronic investigation of land cover changes (1990–2000) in a Mediterranean region with high human pressure (Attica, Greece) was developed in the present study with the aim to profile different agro-forest types and their evolution over time. Changes in the distribution of 31 land cover classes and their spatial relationships have been assessed using(More)
The hemoflagellate protozoan parasite Trypanosoma cruzi is the causative agent of the Chagas disease, a progressive fatal cardiomyopathy that afflicts more than 20 million people in Central and South America. The T. cruzi life cycle is affected by changes in temperature and pH, the parasite replication being facilitated in mammalian hosts rather than in(More)
Variation in growth, arsenic and heavy metal uptakes by aboveground tissues (leaves, stems and branches) of 13 hybrid Eucalyptus clones selected for biomass production in a Mediterranean environment (E. camaldulensis × E. viminalis; E. camaldulesis × E. grandis; E. camaldulensis × E. globulus subsp. bicostata) was investigated on agricultural soils(More)
The detection of leaf functionality is of pivotal importance for plant scientists from both theoretical and practical point of view. Leaves are the sources of dry matter and food, and they sequester CO2 as well. Under the perspective of climate change and primary resource scarcity (i.e. water, fertilizers and soil), assessing leaf photo-assimilation in a(More)
An approach to derive relationships for defining land degradation and desertification risk and developing appropriate tools for assessing the effectiveness of the various land management practices using indicators is presented in the present paper. In order to investigate which indicators are most effective in assessing the level of desertification risk, a(More)
