Per la conservazione partecipata, consapevole e diffusa dell'architettura storica e religiosa

2016

Il saggio Per la conservazione partecipata, consapevole e diffusa dell’architettura storica e religiosa è un contributo per meglio conoscere e dunque conservare, facendo fruire, il patrimonio delle preesistenze architettoniche con destinazione religiosa, partendo dal caso delle chiese di Bagheria, ma proponendo un apporto generale sia per la stessa conservazione, ma anche per il dovuto adeguamento liturgico. Infatti, non solamente s‘impone la conservazione del patrimonio storico e religioso, ma unitamente l’adeguamento liturgico secondo il concilio Vaticano II e dei successivi apporti pastorali offerti dalla Conferenza Episcopale Italiana. Nel saggio si sottolinea che qualsiasi nuova aggiun…

Rapid change in forms of inorganic nitrogen in soil and moderate weed invasion following translocation of wet meadows to reclaimed post‐industrial la…

2019

Anthropogenic expansion and loss of natural environments calls for the more sustainable use of resources, including land. To combine the conservation of highly valuable meadow habitat with reclamation of post‐industrial land, 1.3 ha of turf were translocated from an urban area to basins constructed near an abandoned quarry. In contrast to the usual method of choosing similar habitats as salvage sites, the selected quarry possessed different environmental properties to the meadows, challenging their acclimatisation. To evaluate the project, we monitored three meadows (Molinion caeruleae alliance) for three seasons: immediately before the transfer and for 2 years afterwards. We recorded veget…

CONOSCENZA E CONSERVAZIONE. PROSPETTIVE PER LE DOMUS DI PIAZZA DELLA VITTORIA A PALERMO.

2014

Il tema di ricerca possiede un carattere multidisciplinare, coinvolge ampi settori e, con un approccio metodologico di tipo olistico, mette in evidenza le complessità storiche, artistiche, architettoniche, archeologiche e urbanistiche, tenendo conto delle differenti implicazioni sul piano sia tecnologico che museografico. Il caso di studio scelto, per elaborare una strategia d’intervento e riproponibile in altri contesti, è costituito dalle Domus di Piazza della Vittoria a Palermo, un exemplum di complesso residenziale unico nell’ambito della città, arricchito dalla presenza di importanti mosaici che testimoniano la circolazione di possibili culti praticati nell’area occidentale della Sicil…

Risk map of transmission of urogenital schistosomiasis by Bulinus truncatus (Audouin, 1827) (Mollusca Gastropoda, Bulinidae) in Spain and Portugal

2019

Mapa del riesgo de contraer schistosomiasis urogenital provocada por Bulinus truncatus (Audouin, 1827) (Mollusca Gastropoda, Bulinidae) en España y Portugal Se da a conocer el mapa de la distribución geográfica de Bulinus truncatus en España y Portugal en el que se recopilan las localidades históricas y actuales, que coincide con el mapa del riesgo de contraer schistosomiasis urogenital provocada por este caracol de agua dulce. Se revisan las muestras de esta especie depositadas en el Museu de Ciències Naturals de Barcelona y en el Museo de Ciencias Naturales de Madrid, así como datos propios, incluidas algunas aportaciones inéditas. Este mapa permitirá conocer el área óptima de esta especi…

CHECK-LIST DEGLI UCCELLI DELLA R.N.O. “SALINE DI TRAPANI E PACECO” CON LISTA COMMENTATA DEI NON PASSERIFORMES

2018

Update of the checklist of the birds of the Nature Reserve “Saline di Trapani e Paceco” (Sicily). The present work provides an update to the checklist of birds of the “Saline di Trapani e Paceco” published nine years ago by IENTILE (2008). The overall number of bird species increased from 209 to the current value of 229. The present work also includes a quantitative estimate of the breeding and wintering species. A table, detailing the number of individuals of each species present for each month of the year at the Saline di Trapani and Paceco, is included. This work aims at underscoring the importance of the Saline as an Important Bird Area (IBA), as a key area for the migration pathways of…

Absolute zapovednost’ as an ethical model

2013

There is a substantial difference between protected areas and wildlife sanctuaries. The former are a rational answer to the current decline of biodiversity and, as such, they are widely accepted in our society; the latter respond to an ethical need, which is not very common so far. This is the reason why administrators and public opinion are reluctant to accept the non-usability of areas that, to be preserved, require maintenance, patrolling and monitoring costs. The challenge of increasing the consensus around wildlife sanctuaries goes far beyond the establishment of protected areas. It lies in making desirable a sober lifestyle, with general awareness of the environmental consequences of …

Towards a framework for assessment and management of cumulative human impacts on marine food webs

2015

Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…

The Role of Excited Oxygen Molecules in the Formation of the Secondary Ozone Layer at 87 to 97 km

2018

The secondary ozone layer is located at elevations of 87 to 97 km in the upper mesosphere – lower thermosphere. It overlaps with the ionospheric D-layer. Daytime intensive UV radiation is dissociating O2 molecules to O atoms and photoexcitating O2 molecules up to 11.07eV level. Ozone photolysis between the wavelengths of 118.7–121.6 nm produces three oxygen atoms from one ozone molecule. Collision reactions of O2(B3 Σu —) and O2(X3 Σg —, υ≥26) with O2(X3 Σg —, υ=0) produce additional oxygen atoms. The number of oxygen atoms is maintained at such a high level that a small but significant ozone concentration survives. UV radiation weakens radically during the night. The number of O atoms show…

Investigations into the development and role of a Mediterranean intertidal bioconstruction for coastal conservation: the Vermetid Reef

2017

Vermetid reefs are intertidal biogenic habitats created by a dense aggregation of mollusks, frequently cemented by calcareous algae, and are typical of sub-tropical and warm–temperate rocky shores. These bioconstructions are valuable key-habitats of the coastal zones, increasing their productivity and biological value. In the Mediterranean, the main vermetid reef builders belong to the genus Dendropoma and are associated to encrusting coralline red algae. These organisms are ecosystem engineers protected under international European Legislation, although vermetid reef conservation is limited by a lack of biological and ecological knowledge. The two-way interactions between biota and the phy…
