Case Study of Potential Production of Renewable Energy Sources (RES) from Livestock Wastes in Mediterranean Islands

2017

The aim of this work is to evaluate the potential production of Renewable Energy Sources (RES) from livestock wastes that are commonly found on Mediterranean islands, by using the island of Malta as a case study. Organic wastes in the form of livestock manure and slurry, as well as other by-products originating from the food transformation industry in the making of alcoholic beverages and the processing of olives, tomatoes and other streams, if mixed in such a way to achieve a correct C/N ratio, can be subjected to anaerobic co-digestion for the production of biogas and digestate. Biogas can be further transformed into biomethane, a fuel that can be used to power surface transportation and …

The genus Bolbelasmus in the western and southern regions of the Mediterranean Basin (Coleoptera: Geotrupidae: Bolboceratinae)

2016

The Bolbelasmus Boucomont, 1911 species of the western and southern regions of the Mediterranean Basin (Northern Africa, Iberian Peninsula and France) are revised. The following three new species are described: Bolbelasmus brancoi Hillert & Král sp. nov. and Bolbelasmus howdeni Hillert & Král sp. nov., both from Spain and Gibraltar, and Bolbelasmus nikolajevi Hillert, Arnone, Král & Massa sp. nov. from Egypt, Libya and Tunisia. Bolbelasmus vaulogeri (Abeille de Perrin, 1898) stat. restit. is removed from synonymy with B. bocchus (Erichson, 1841) and reinstated as a separate species. Bolbelasmus romanorum Arnone & Massa, 2010 is considered a junior subjective synonym of B. vaulogeri. Lectoty…

Biodiversity of the orophilous communities of Pino-Juniperetea class in the Central and Eastern Mediterranean area.

2000

The authors examine the orophilous communities, occuring in the Central and Eastern Mediterranean area, characterized by the dominance of trees and shrubs belonging to the genera Juniperus, Abies and Pinus. These communities are localized in the supra- and oromediterranean belt and show a relict role. From the structural point of view, this kind of vegetation is usually bistratified, with a low dense shrubby layer and spaced tree layer; sometime the latter one is absent. This vegetation is floristically poor and characterized by prevalence of Coniferous, such as Juniperus sabina, J. foetidissima, J. excelsa, J. oxycedrus. J. hemisphaerica, J. communis, J. nana, Abies nebrodensis, A. alba, A…

First record and morphological features of Hemidiaptomus (Occidodiaptomus) ingens (Gurney, 1909) (Copepoda Calanoida) in Italy

2004

During a survey, carried out to assess the consistency of microcrustacean fauna inhabiting temporary ponds in Sicily, Hemidiaptomus (Occidodiaptomus) ingens (Gurney, 1909), a large calanoid copepod up to now known only for North-African ponds, Camargue and Corse, was found in the north-western part of the island. Due to its central location in the Mediterranean Sea, Sicily represents a transition zone where several chorological zones of the West Palearctic merge and converge. A brief summary of the existing literature regarding this taxon is given with some morphological considerations on the recently found population which represents the first record for Italy. In particular, the morpholog…

The genus Ruppia L. (Ruppiaceae) in the Mediterranean region: An overview

2015

Abstract This paper reviews the current knowledge on the diversity, distribution and ecology of the genus Ruppia L. in the Mediterranean region. The genus Ruppia, a cosmopolitan aquatic plant complex, is generally restricted to shallow waters such as coastal lagoons and brackish habitats characterized by fine sediments and high salinity fluctuations. In these habitats Ruppia meadows play an important structural and functional role. Molecular analyses revealed the presence of 16 haplotypes in the Mediterranean region, one corresponding to Ruppia maritima L., and the others to various morphological forms of Ruppia cirrhosa (Petagna) Grande, all together referred to as the “R. cirrhosa s.l. co…

Sustainable tourism: Measures, evidence and future prospects.

2021

The Chapter aims to provide a critical review of the quantitative approaches so far introduced in literature to measure the sustainable tourism. We focus on both variables and methods employed to obtain synthetic indicators of sustainable tourism and aim to provide some critical insights on potential new challenges caused by the current pandemic. For example, some dimensions of tourism sustainability may become more relevant in future due to the increasing attention by people on health and safety. Finally, a focus on the studies on measurement of sustainable tourism in the Mediterranean area will be provided.

Syntaxonomical survey of Geranio-Cardaminetalia hirsutae: Semi-natural therophytic vegetation of the Mediterranean region

2007

A syntaxonomical scheme, including geographical range and synonymies of all the associations ascribed to Geranio-Cardaminetalia hirsutae, is presented. This order, framed into the class Stellarietea mediae, groups sciaphilo-subnitrophilous annual vegetation of natural and semi-natural habitats, commonly occurring on substrata rich in organic matter, accumulating on stone-walls, shaded rocks and initial soils, often under the canopy of shrubs and trees. Twelve new associations from Sardinia, Sicily, Egean islands and Israel are here described for the first time.

Verde pensile estensivo ad alto valore ecologico in ambiente mediterraneo. Aspetti progettuali e funzionali

2013

Green areas are open spaces holding an unexpected kind of local biodiversity within the city, linked to species and habitats frequently found in human settlements. Green roofs can be an important means for environmental mitigation and, if designed according to the principles of restoration ecology, can improve the thermodynamic performance / hydraulic system and at the same time encouraging the development of urban biodiversity. With this work, we propose a methodology approach for green roofs in Mediterranean areas, that integrate aesthetic values with the functional traits of native species, in order to make green roofs “local tanks of biodiversity”.

What is a tree in the Mediterranean Basin hotspot? A critical analysis

2019

Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-Europ…
