Conservation status of the Italian flora under the 92/43/EEC ‘Habitats’ Directive
2021
The results of the 4th National Report for the Italian flora under the 92/43/EEC ‘Habitats’ Directive are presented. The outcomes showed a general negative conservation status for plant species, with the worst situation being in the Mediterranean bioregion. At the National level, significant monitoring and conservation activities are required.
Les prélèvements paléoenvironnementaux et géoarchéologiques : principes de conservation et orientations pour le tri / sélection
2020
International audience; Ce travail propose un questionnement sur les modalités de conservation des prélèvements paléoenvironnementaux et géoarchéologiques qui ont été réalisés dans le cadre de recherches archéologiques, en prenant en compte leur intérêt scientifique et leur statut patrimonial. Il s’interroge également sur la question de l’intérêt scientifique de ces restes dans le cadre des discussions en cours. Celles-ci interviennent dans le cadre des procédures de conservation sélective des biens archéologiques mobiliers, introduit par l’ordonnance du 29 juin 2017 relative aux règles de conservation, de sélection et d’étude du patrimoine archéologique mobilier. Construit comme une synthè…
Farming intensity indirectly reduces crop yield through negative effects on agrobiodiversity and key ecological functions
2022
International audience; Farming intensity and landscape heterogeneity influence agrobiodiversity and associated ecological functions. The relative contributions of these agroecosystem components to agricultural production remain unclear because of inter-relations and weather-dependant variations. Using a structural equation modelling approach, we estimated direct and indirect contributions of farming intensity (soil management, pesticide use and fertilisation) and landscape heterogeneity (of semi-natural covers and crop mosaic) to cereal crop production, in 54 fields (mostly wheat), in two years (24 and 30 fields). Indirect effects were evaluated through agrobiodiversity (carabid and plant …
Woodland key habitats : a key to effective conservation of forest biodiversity?

From ambient to preserve the cold at ambient to preserve and to exhibit contemporary art: the "pit of snow" of villa Cattolica (SIcily) - Da ambiente…

Sino a quando non sono stati inventati i moderni sistemi di refrigerazione, il compito di mantenere temperature basse era demandato a speciali architetture. Nel Meridione d’Italia e in particolare in Sicilia detto compito era affidato alla “fossa della neve”. In generale trattasi di un ambiente ipogeo nel quale veniva conservata la neve, per essere, nella sua maggiore quantità, utilizzata, nella tarda primavera e nella torrida stagione estiva, per la produzione di gelati e bevande fresche. Nella città di Palermo e nelle sue campagne circostanti non vi era palazzo, convento o villa che non possedeva una “fossa della neve”. Infatti numerosi sono i documenti di archivio che ci informano sulla …
The impact of regional demographics on Higher Education Policy. An example from Silesia, Poland
2021
Abstract The determinants of higher education policy have their sources in various spheres, such as economic, social, educational, national policy, administrative, and demographic. Problems for the development of higher education also stem from these spheres. One of them is the challenging demographic situation that is a significant element of developing higher education in southern Poland (particuarly in the Silesia region). Given this context, this article aims to indicate the policies of the universities in the region which respond to the existing demographic threats. This relationship is to confront student opinions regarding their vision for their education and future career within the…
Alarmist by bad design: Strongly popularized unsubstantiated claims undermine credibility of conservation science
2019
“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades.” or “Our work reveals dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over the next few decades.” These are verbatim conclusions of the recent paper by Sánchez-Bayoa and Wyckhuys (2019) in Biological Conservation. Because of fundamental methodological flaws, their conclusions are unsubstantiated. Like noted by The Guardian, the conclusions of the paper were set out in unusually forceful terms for a peer-reviewed scientific paper. The current case…
From Analysis to Formulation of Strategies for Farm Advisory Services (Case Study: Valencia – Spain). an Application through Swot and Qspm Matrix
2019
Abstract European agriculture should meet new increasing internal and contextual challenges. For example, the reform of the Common Agricultural Policy in 2003 introduced the cross-compliance, among other novelties, as compulsory for farmers. To better meet this and other requirements, Member States had to set up the so-called Farm Advisory System, operational across the European Union in 2007. From a sample of actors involved in the provision of farm advisory services in the region of Valencia (Spain), the present study aimed to identify the most appropriate strategies to implement such services. SWOT method has been applied to examine the internal and external environment. Based on this di…
Étude des traces de pas de vertébrés du Permien et du Trias d'Ardèche. Enjeux et perspectives.
2022
Le département de l'Ardèche estremarquable car il offre un accès privilégié auxroches sédimentaires permiennes et triasiques danslesquelles abondent les traces de vertébrés fossiles.Une vingtaine de localités et plus de 1500empreintes de pas ont déjà été recensées le longd'une succession sédimentaire affleurant entrePrivas et Les Vans. Ce patrimoine ichnologique,reconnu internationalement, documente le passagede grands groupes de reptiles en terres ardéchoises,incluant essentiellement des représentants basauxde la lignée des crocodiles (pseudosuchiens) et de lalignée des oiseaux (dinosauriformes et dinosaures),ainsi que quelques membres de la lignée des lézards/serpents (lépidosauromorphes)…
The new “Vegetation map of Sicily (Italy)”: a synthetic overview of the distribution of European habitats on the territory.
2016
The new "Vegetation map of Sicily (Italy)", recently published (Gianguzzi, Papini & Cusimano, 2015), shows also a synthetic overview of the distribution of European habitats in the territory; the study area has been extended to small islands circum-Sicilian (archipelago of the Aeolian; Aegadian, Pelagie Ustica and Pantelleria islands), for a total area of 25,703 km2. Our work allowed to resume the knowledge status of the phytosociological studies on vegetation carried out and to identify the actual plant landscape of the region; the map was compiled in a Geographical Information Systems (GIS) environment, in order to produce a cartographic representation in 1:10,000 scale (reduced to a 1:25…
