Living Coccolithophores from the Gulf of Sirte (Southern Mediterranean Sea) during the summer of 2008
2012
The Gulf of Sirte is a largely unexplored area in the southernmost Mediterranean Sea.We are presenting here 2008 summer data on the distribution pattern of living coccolithophores, a main phytoplankton calcifying group, in 105 samples from 20 stations. The survey includes coastal and offshore stations, enabling us to provide indications on the dynamics of phytoplankton productivity in relation to oceanographic processes. The total coccosphere concentrations show higher values in the offshore stations and lower ones for coastal sites. Umbellosphaera tenuis, Emiliania huxleyi, Florisphaera profunda, Syracosphaera pulchra HOL (Calyptrosphaera oblonga) and Rhabdosphaera spp. dominate the assemb…
Priorities and gaps in Mediterranean bat research evidence: a systematic review for the early twenty-first century
2022
Bat conservation is one of the top global concerns for research today; however, conservation efforts may still be limited and impotent due to inadequacy and scarcity of data. Hence, identifying research trends, threatening factors, species status, and geographical priorities is an essential tool for future conservation, protection and prioritization. Here we conduct a comprehensive systematic review to identify current research priorities, trends, general patterns and gaps regarding Mediterranean bat researches. A total of 97 studies were found in the years spanning between 2000 and 2021. There were 18 studies with sufficient data for qualitative statistical analysis to investigate the impa…
Red list of threatened vascular plants in Italy
2021
Italy has a rich natural heritage, which is dangerously under pressure. In recent years, there is an increased awareness of the crucial role of plants in ecosystem functioning and in providing ecosystem services. Consequently, an updated Red List of the Italian vascular flora was compiled in this work, at the request of the Ministry for Environment, Land and Sea Protection, with the scientific support of the Italian Botanical Society. The IUCN Red List criteria were applied to 2,430 Italian native vascular plant taxa to assess their current extinction risk and to highlight the major threats affecting the Italian flora. Our results revealed that 54 taxa (2.2% of the assessed taxa) are extinc…
Presencia y análisis genético de una tortuga bastarda (Lepidochelys kempii) en el mar Mediterráneo
2003
We report on a juvenile Kemp´s ridley sea turtle, Lepidochelys kempii, captured alive by fishermen in the waters off Alicante (western Mediterranean, Spain) on October 15th 2001. The analysis of a 460 base pair fragment of the mt DNA control region revealed a perfect match with haplotype D previously described in this species. This is the second report of L. kempii in the Mediterranean basin.
Tourism in Mediterranean Islands: a comparative analysis.
2011
This chapter analyses the main dimensions of 24 Mediterranean islands representing seven European countries. It highlights some of the economic barriers to sustainability. Islands are classified by area into large, medium, small and micro, and also by population density- from high to low. The Mediterranean islands represent a wide variety of situations and common problems, and every economic decision has had an immediate impact on the sustainability of the economies of each island.
Helminth Infection of the Loggerhead Sea Turtle Caretta caretta along the Coasts of Sicily and the North West Adriatic Sea
2021
We provide new data on the presence of helminth parasites in 64 individual loggerhead sea turtles Caretta caretta stranded along the coasts of Sicily and the northwest Adriatic Sea between June 2014 and August 2016. The necropsy examination revealed 31 individuals (48.4%) positive for endoparasites, showing a greater prevalence of trematodes than nematodes. In particular, seven species and a single genus of Trematoda (Hapalotrema) and a single species and genus of Nematoda (Kathlania) were identified. Among the Digenea flukes the species with the highest prevalence of infection were Rhytidodes gelatinosus (34.6%) and Hapalotrema sp. (33.3%), while among the Nematoda they were Kathlania sp. …
The controversial role of actors in Italian and Sicilian waterfront areas management and planning
2013
The paper investigates the relationship between planning tools and formal/informal subjects involved in Sicilian waterfront areas management and it focuses on the relation between port plans and other (local and regional) planning instruments and policies. This relationship is explored through an examination of some results of The “Waterfront” project (Water And Territorial policiEs for integRation oF multisectoRial develOpmeNT), developed under the PO 2007-2013 Italia-Malta, that aimed to explore the field of “waterfront” in a different sense from the simple concept of urban or peri-urban coastal areas. The waterfront, in the Project approach, takes a wider identity that refers to the comp…
Pyrus pedrottiana (Rosaceae), a new species from the Nebrodi Mountains (N-E Sicily)
2022
A new species of Pyrus for the dendroflora of Sicily is here described. It is Pyrus pedrottiana, actually considered endemic to the Nebrodi Mountains, a territory which includes the largest wooded area of the island with a high forest biodiversity.In the same area, P. vallis-demonis and P. ciancioi have also been described in recent times. The authors report diagnostic characters to distinguish the new taxon from the other two sympatric species.
EFFETTI DELLA PROTEZIONE E DELLA COMPLESSITÀ TOPOGRAFICA SUI POPOLAMENTI BENTONICI DEI REEF A VERMETI
2009
Vermetid reef can be considered a key intertidal habitat of Mediterranean Sea and increasing knowledge about this natural system is important for its conservation. Aims of this study is to assess topography complexity, structure and composition of the benthic assemblages associated to reef formation in a marine protected area highlighting possible effects of the protection.
Visual Methodologies and Geography's education in the pandemic time: notes on geopolitics of migration in the "Mediterranean Complex"
2022
<abstract> <p>The relationship between Geography and the Visual has always been strong intertwined. As it is true that Geography has always operates through images (in the form of pictures, creative representations and above all cartographies), in the last two years, with the distance learning due to the spread of the Covid-19 pandemic, this phenomenon has not only increased, but it also became necessary. "The classroom as the most radical space", in the words of bell hooks, had to turn into a virtual space, where images have a fundamental role in the teaching/learning process. This paper wants to analyse the relationship between Geography and the Visual by analysing three image…
