Seawater carbonate chemistry and shell mineralogy, microstructure, and mechanical strength of four Mediterranean gastropod species near a CO2 seep

2017

Marine CO2 seeps allow the study of the long-term effects of elevated pCO2 (ocean acidification) on marine invertebrate biomineralization. We investigated the effects of ocean acidification on shell composition and structure in four ecologically important species of Mediterranean gastropods (two limpets, a top-shell snail, and a whelk). Individuals were sampled from three sites near a volcanic CO2 seep off Vulcano Island, Italy. The three sites represented ambient (8.15 pH), moderate (8.03 pH) and low (7.73 pH) seawater mean pH. Shell mineralogy, microstructure, and mechanical strength were examined in all four species. We found that the calcite/aragonite ratio could vary and increased sign…

Individual and population-level responses to ocean acidification

2016

Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts on specific species, few studies have simultaneously considered the effects of ocean acidification on individuals (e.g. consequences for energy budgets and resource partitioning) and population level demographic processes. Here we show that ocean acidification increases energetic demands on gastropods resulting in altered energy allocation, i.e. reduced shell size but increased body mass. When scaled up to the population level, long-term exposure to ocean acidification altered population demography, with evidence of a reduction in the pr…

Trace elements in shells of common gastropods in the near vicinity of a natural CO&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt; vent: no evidence of pH-de…

2014

Abstract. There is concern that the use of natural volcanic CO2 vents as analogs for studies of the impacts of ocean acidification on marine organisms are biased due to physiochemical influences other than seawater pH alone. One issue that has been raised is whether potentially harmful trace elements in sediments that are rendered more soluble and labile in low pH environments are made more bioavailable, and sequestered in the local flora and fauna at harmful levels. In order to evaluate this hypothesis, we analyzed the concentrations of trace elements in shells (an established proxy for tissues) of four species of gastropods (two limpets, a topshell and a whelk) collected from three sites …

The Criteria for the Formation of a Frisian Runic Corpus Revisited

1998

The Frisian corpus of runic inscriptions consists of about twenty items, some of which are very short, while other present several problems of legend and interpretation. On the other end, it is undeniable that the Frisian runic inscriptions constitute a uniform corpus with a recognizable identity that can be pinpointed through a series of specific criteria. In the present paper I enter the debate about the origin of the Frisian runic inscriptions, analysing the geographical, linguistical and epigraphic criteria identified by the previous research, providing whenever possible further and new elements, in order to strengthen the foundations of the Frisian runological tradition.

Gamma Vel cluster membership and IMF

2016

Understanding the properties of young open clusters, such as the Initial Mass Function (IMF), star formation history and dynamic evolution, is crucial to obtain reliable theoretical predictions of the mechanisms involved in the star formation process. We want to obtain a list, as complete as possible, of confirmed members of the young open cluster Gamma Velorum, with the aim of deriving general cluster properties such as the IMF. We used all available spectroscopic membership indicators within the Gaia-ESO public archive together with literature photometry and X-ray data and, for each method, we derived the most complete list of candidate cluster members. Then, we considered photometry, gra…

Instability Resistance Training Across the Exercise Continuum

2013

Context: Instability resistance training (IRT; unstable surfaces and devices to strengthen the core or trunk muscles) is popular in fitness training facilities. Objective: To examine contradictory IRT recommendations for health enthusiasts and rehabilitation. Data Sources: A literature search was performed using MEDLINE, SPORT Discus, ScienceDirect, Web of Science, and Google Scholar databases from 1990 to 2012. Study Selection: Databases were searched using key terms, including “balance,” “stability,” “instability,” “resistance training,” “core,” “trunk,” and “functional performance.” Additionally, relevant articles were extracted from reference lists.

Iberian Distribution of the Freshwater Snail Genus Bithynia Leach, 1818 (Mollusca: Truncatelloidea), Vector of Opisthorchiasis and Metorchiasis

2021

Background: Opisthorchis felineus and Metorchis bilis are trematodes that cause opisthorchiasis and metorchiasis, respectively. The freshwater snails Bithynia hispanica and B. tentaculata are the respective intermediate hosts for these parasites in the Iberian Peninsula, where both parasites are present. Methods: To study the distribution of these snail species, an exhaustive literature review and revision of museum collections was performed. Results: A total of 370 localities were compiled and mapped. B. tentaculata were found throughout the Iberian Peninsula, both in Spain and Portugal, while B. hispanica was found only in the Mediterranean coast of Spain. Conclusion: Knowing the distribu…

Organisierte Kriminalität. Die Mafia: globale Szenarien und internationale Connections

2012

Lo studio dei fenomeni criminali di tipo mafioso rende necessaria una costante attività di confronto, verifica e aggiornamento dei paradigmi di analisi; è normale, del resto, che ogni fenomeno sociale letto ed esaminato entro uno specifico universo di significazione, meriti una nuova attenta ricognizione per verificare se siano cambiate o meno le sue peculiari caratteristiche, quando il contesto di riferimento muta e l’oggetto di studio assume connotazioni differenti. Il saggio analizza in chiave diacronica e comparativa i processi di trasformazione che hanno interessato le principali organizzazioni criminali italiane, proiettando le loro attività all'interno di uno scenario globale. Nel co…
