Helminth infracommunities of gallotia caesaris caesaris and gallotia caesaris gomerae (sauria: lacertidae) from the Canary islands (eastern Atlantic)
2004
A survey of gastrointestinal helminth communities of Gallotia caesaris caesaris (Lehrs, 1914) and G. c. gomerae (Boettger and Müller, 1914), from the islands of El Hierro and La Gomera, respectively, in the Canary Archipelago, Spain, was conducted to determine the prevalence, intensity, and diversity of intestinal parasites of these lacertid lizards. Larval forms of cestodes, nematodes, and acanthocephalans were found in the body cavity of G. c. caesaris; this lizard is the intermediate or paratenic host in the life cycle of these helminths. Pharyngodonid nematodes were the most common intestinal helminths in both hosts, 4 of them being Gallotia spp. specialists. Helminth infracommunities o…
De l'Estudi General a la Universitat de les Illes Balears
2020
Resum: L’Estudi General de la Ciutat de Mallorca, creat el 1483, concedia graus en teologia, filosofia i arts, vàlids únicament en el territori de la monarquia hispànica. Des de mitjan segle xvi va haver d’afrontar la competència del col·legi dels jesuïtes. Per superar aquesta pugna sol·licità i obtingué (1673) que el papat reconegués las validesa dels seus títols a tota la cristiandat. Les dificultats econòmiques retardaren el funcionament d’aquesta universitat fins el 1691. Rebé el nom de Universitat Lul·liana de Mallorca. El 1772 passà a denominar-se Universitat Literària de Mallorca. El 1842 se suprimí definitivament. A Mallorca no hi tornà haver estudis universitaris fins a 1967, i el …

Geochemistry and isotope composition (Sr, Pb, δ66Zn) of Vulcano fumaroles (Aeolian Islands, Italy)
2018
We present and discuss temperatures, major and trace element gas geochemistry, radiogenic isotopes (Pb, Sr) and the first Zn isotope data of fumarole condensates and altered rocks from the Vulcano fumarolic field. The fumaroles of the La Fossa cone, sampled on 5th May 2015, have temperatures ranging between 233 and 427 °C. They plot compositionally on the mixing trend between the magmatic and hydrothermal end-members defined by previous studies, but are strongly displaced towards the hydrothermal component. Correlations of radiogenic (Sr, Pb) and stable isotopes of Zn with δ13CCO2 and several trace elements of the fumarolic acid condensates support mixing between the above mentioned distinc…
Manure as a potential source of renewable energy: The behaviour and characterisation of biofuels generated from three animal manure types when subjec…
2020
Regions with high livestock density lack sufficient land on which to apply manure without exceeding the legal limits set by the European Union Directives. The lack of manure processing alternatives aggravates the situation, especially in the case of islands. Consequently, manure becomes a liability rather than an asset. Results indicate that pyrolysis is an option for manure processing. However, a significant limitation is the moisture content of the starting material, that could compromise the process efficiency. Yields of biogas, bio-oil and biochar, all of which have a potential use as biofuels, are particular to animal type and manure handling system. The conversion of manure to biofuel…
The state of water resources in major mediterranean islands
2014
This work analyses the state of water resources in six Mediterranean islands: Corsica, Crete, Cyprus, Mallorca, Malta and Sicily. The analysis is focused on the prevailing social, economic and hydroclimatological characteristics of these islands in order to identify the main common features affecting water availability, demand and use. A detailed analysis of the state of water resources in all the considered islands has been carried out. A background of current conditions relating to freshwater availability, quality and use has been established. Different strategies to face water scarcity and enhance water quality in theislands have been assessed in a context of climate change which is a co…
A Preliminary Energy Assessment to Improve the Energy Sustainability in the Small Islands of the Mediterranean Sea
2020
Power plants supplied by renewable energy sources are expanding around the world, in order to reduce the carbon dioxide emissions, limit the global warming and improve the energy sustainability. Despite the relevant achieved results, small islands are heavily reliant on fossil fuels. In this context, renewable energy sources are available but practically unused, due to landscape and economic constraints. This condition is quite common in the Mediterranean Sea. These islands are normally fed by a stand-alone electrical grid and a power plant, equipped with diesel engines. In order to improve the sustainability of the energy sector, the paper considers the case study of Ustica, a small Italia…
Wickerhamomyces sylviae f.a., sp. nov., an ascomycetous yeast species isolated from migratory birds.
2013
In the present work, we investigated the phylogenetic position and phenotypic characteristics of eight yeast isolates collected from migratory birds on the island of Ustica, Italy. A phylogenetic analysis based on the D1/D2 region of the large-subunit rRNA gene showed that all isolates clustered as a single separate lineage within the Wickerhamomyces clade. They exhibited distinct morphological and physiological characteristics and were clearly separated from their closest relatives, Wickerhamomyces lynferdii, Wickerhamomyces anomalus and Wickerhamomyces subpelliculosus, in blastn searches. On the basis of the isolation source, physiological features and molecular strain typing carried out …

On the Impact of Heat Pumps Electric Load on the Power Consumption of Lampedusa
2020
The present paper reports the results of a simulation study regarding the impact of the adoption of heat pumps for domestic hot water production in the island of Lampedusa (Italy). In the study, it has been assumed to replace electric storage water heaters with heat pumps at every dwelling of the about four thousand domestic end-users of the island and, in addition, to control the heat pump operation in order to enhance some parameters that characterize the quality of the generation and distribution system of the island (power peak, energy losses and voltage drop). According to the results of the simulations, while the replacement of electric storage water heaters with heat pumps is able to…
