Seawater carbonate chemistry and coralline algal diversity
2021
Calcified coralline algae are ecologically important in rocky habitats in the marine photic zone worldwide and there is growing concern that ocean acidification will severely impact them. Laboratory studies of these algae in simulated ocean acidification conditions have revealed wide variability in growth, photosynthesis and calcification responses, making it difficult to assess their future biodiversity, abundance and contribution to ecosystem function. Here, we apply molecular systematic tools to assess the impact of natural gradients in seawater carbonate chemistry on the biodiversity of coralline algae in the Mediterranean and the NW Pacific, link this to their evolutionary history and …
Decline in Coccolithophore Diversity and Impact on Coccolith Morphogenesis Along a Natural CO2 Gradient
2014
A natural pH gradient caused by marine CO2 seeps off Vulcano Island (Italy) was used to assess the effects of ocean acidification on coccolithophores, which are abundant planktonic unicellular calcifiers. Such seeps are used as natural laboratories to study the effects of ocean acidification on marine ecosystems, since they cause long-term changes in seawater carbonate chemistry and pH, exposing the organisms to elevated CO2 concentrations and therefore mimicking future scenarios. Previous work at CO2 seeps has focused exclusively on benthic organisms. Here we show progressive depletion of 27 coccolithophore species, in terms of cell concentrations and diversity, along a calcite saturation …
Shallow water marine sediment bacterial community shifts along a natural CO2 gradient in the Mediterranean Sea Off vulcano, Italy
2014
The effects of increasing atmospheric CO(2) on ocean ecosystems are a major environmental concern, as rapid shoaling of the carbonate saturation horizon is exposing vast areas of marine sediments to corrosive waters worldwide. Natural CO(2) gradients off Vulcano, Italy, have revealed profound ecosystem changes along rocky shore habitats as carbonate saturation levels decrease, but no investigations have yet been made of the sedimentary habitat. Here, we sampled the upper 2 cm of volcanic sand in three zones, ambient (median pCO(2) 419 µatm, minimum Omega (arag) 3.77), moderately CO(2)-enriched (median pCO(2) 592 µatm, minimum Omega (arag) 2.96), and highly CO(2)-enriched (median pCO(2) 1611…

Le sequenze procedimentali “obbligate” in caso di trasgressione dell’ordine di espulsione o di allontanamento ex artt. 235 e 312 c.p.
2008
Le disposizioni introdotte nel codice penale e in quello di rito, dal c.d. "pacchetto sicurezza" del 2008, si pongono - per certi versi - sul solco di modifiche precedentemente apportate dal legislatore con la c.d. "legge Bossi-Fini", proseguendo così un cammino già intrapreso. Nell'affrontare le principali innovazioni in tema di "lotta all'immigrazione illegale", l'Autore si sofferma principalmente su quelle riguardanti l'espulsione, nella sua veste di misura di sicurezza, la fattispecie dell'arresto anche fuori dai casi di flagranza, nonché le dinamiche del giudizio direttissimo, "tipico" e "atipico".
Effects of ocean acidification on embryonic respiration and development of a temperate wrasse living along a natural CO2 gradient
2016
Volcanic CO2 seeps provide opportunities to investigate the effects of ocean acidification on organisms in the wild. To understand the influence of increasing CO2 concentrations on the metabolic rate (oxygen consumption) and the development of ocellated wrasse early life stages, we ran two field experiments, collecting embryos from nesting sites with different partial pressures of CO2 [pCO2; ambient (400 µatm) and high (800-1000 µatm)] and reciprocally transplanting embryos from ambient- to high-CO2 sites for 30 h. Ocellated wrasse offspring brooded in different CO2 conditions had similar responses, but after transplanting portions of nests to the high-CO2 site, embryos from parents that sp…
The European Flag According to Paolo Fabbri
2021
Too often we consider symbols in our cultures to be indivisible monoliths that can only be interpreted through the connotations they take on over time. This is due, on one hand, to their compact nature, the correspondence between the planes of expression and content that make them appear solid, impossible to break down. However, it is also true that in the majority of cases we inherit ready-made symbols that seem to have been born with their current shape, with no hint as to the processes that have made them this way. As a rule, there are so many, varied meanings of the word “symbol” that, in the absence of a clear, consensual hypothesis on what a symbol is, they can be difficult to read. A…

Management strategies of infiltrated businesses
2015
The contribution analyses how businesses infiltrated by Organised Crime Groups are managed, and identifies differences between infiltrated and legal businesses in order to highlight accounting and non-accounting ‘red flags’ that can be used in a risk assessment model of criminal infiltration
