Modeling Fire Danger in Galicia and Asturias (Spain) from MODIS images
2014
Forest fires are one of the most dangerous natural hazards, especially when they are recurrent. In areas such as Galicia (Spain), forest fires are frequent and devastating. The development of fire risk models becomes a very important prevention task for these regions. Vegetation and moisture indices can be used to monitor vegetation status; however, the different indices may perform differently depending on the vegetation species. Eight different spectral indices were selected to determine the most appropriate index in Galicia. This study was extended to the adjacent region of Asturias. Six years of MODIS (Moderate Resolution Imaging Spectroradiometer) images, together with ground fire data…
The European Union can afford greater ambition in the conservation of its threatened plants
2021
The importance of Natura 2000 network for the conservation of natural habitats, wild flora and fauna at European level is undeniable. However, it may not have reached its full potential since the loss of biodiversity continues to increase year on year. Further on, a third of the plant species listed in the Habitats Directive to guide the declaration of European Union Natura 2000 network of protected areas is not threatened and there is broad agreement on the need to review and update the species list. Here, the effectiveness of Natura 2000 in the conservation of Spanish bryophytes and vascular plants included in the Habitats Directive Annex II is analysed and compared with the one offered t…

Stroboscopic XMCD-PEEM Imaging
2007
Abstract This article summarizes recent results on magnetization dynamics obtained with time-resolved photoemission electron microscopy (PEEM) using X-ray magnetic circular dichroism as contrast mechanism. Time resolution is performed by a stroboscopic technique that is exclusively sensitive to reversible processes, but offers a very high time resolution only limited by the X-ray pulse width. A time resolution of 20 ps in combination with a lateral resolution of 100 nm has been achieved.
Pinus halepensis M. versus Quercus ilex subsp. Rotundifolia L. runoff and soil erosion at pedon scale under natural rainfall in Eastern Spain three d…

Abstract Afforestation aims to recover the vegetation cover, and restore natural ecosystems. The plant species selected for restoration will determine species richness and the fate of the ecosystem. Research focussing on the impact of vegetation recovery on soil quality are abundant, especially on fire affected land and where rehabilitation, afforestation and restoration projects were carried out. However, little is known about how different plants species affect soil erosion and water losses, which are key factors that will impact the fate of the afforested land. Aleppo pine (Pinus halepensis M.) is the species commonly used for afforestation in the Mediterranean and is very successful whe…
Arti applicate nell'Abbazia di Santa Maria del Bosco di Calatamauro. Note storiche e documenti
2006
Si analizza il patrimonio d'arte decorativa dell'abbazia di Santa Maria del Bosco di Calatamauro, in larga parte disperso e perlopiù ormai noto soltanto attraverso i documenti d'archivio We analyze the decorative art heritage of the abbey of Santa Maria del Bosco di Calatamauro, largely dispersed and mostly known only through archival documents
Confronto tra differenti metodologie di valutazione della qualità fisica del suolo in un’area a pascolo e bosco della Sicilia
2016
Il concetto di qualità fisica del suolo (SPQ, Soil Physical Quality) viene ormai largamente utilizzato, soprattutto in ambito agricolo. Un suolo agricolo di buona qualità fisica possiede caratteristiche strutturali favorevoli sia all’ancoraggio della coltura sia allo sviluppo dell’apparato radicale della pianta nonché un’adeguata ripartizione tra pori di diverse dimensioni, in modo da favorire simultaneamente l’areazione e la ritenzione idrica nel mezzo poroso. Per la valutazione della SPQ sono determinanti le misure di ritenzione idrica del suolo, che possono essere analizzate con diverse metodologie. Alcune indagini recenti segnalano tuttavia che la scelta della metodologia di analisi del…
L’acarofauna utile (Parasitiformes, Phytoseiidae) associata alle specie forestali del sito Natura 2000 “Bosco di S. Adriano”
2008
Within the acarofauna present in ecosystems, the Phytoseiidae family has a relevant role as it includes species considered as the most important biocontrol agents of phytophagous mites. Their specific composition in various habitats is influenced by numerous factors both biotics and abiotics, while the number of species increases if the complexity of the ecosystem increases. In order to know the specific composition of phytoseiid mites in two natural habitats and to check possible changes in a near future, a survey of phytoseiid mites was carried out in a Natura 2000 location S. Adriano woods (Sicily). This research was done within the project ManagMED “Integrated development and management…
