High-Frequency Dynamics of Ocean pH: A Multi-Ecosystem Comparison
A compilation of continuous, high-resolution time series of upper ocean pH, collected using autonomous sensors, over a variety of ecosystems ranging from polar to tropical, open-ocean to coastal, kelp forest to coral reef, reveals a continuum of month-long pH variability with characteristic diel, semi-diurnal, and stochastic patterns of varying amplitudes.

Alien species in the Mediterranean Sea by 2010. A contribution to the application of European Union's Marine Strategy Framework Directive (MSFD). Part I. Spatial distribution
The state-of-art on alien species in the Mediterranean Sea is presented, making distinctions among the four subregions defined in the EU Marine Strategy Framework Directive; the WMED hosts most invasive macrophytes, whereas the EMED has the lion’s share in polychaetes, crustaceans, molluscs and fish.

Alien species in the Mediterranean Sea by 2012. A contribution to the application of European Union’s Marine Strategy Framework Directive (MSFD). Part 2. Introduction trends and pathways
There is an increasing trend in new introductions via the Suez Canal and via shipping, while Lessepsian species decline westwards, while the reverse pattern is evident for ship-mediated species and for those introduced with aquaculture. Expand
Mass mortality in Northwestern Mediterranean rocky benthic communities: effects of the 2003 heat wave
Late in summer 2003, extensive mass mortality of at least 25 rocky benthic macro-invertebrate species (mainly gorgonians and sponges) was observed in the entire Northwestern (NW) MediterraneanExpand
Divergent ecosystem responses within a benthic marine community to ocean acidification
Shallow water CO2 vents in the Mediterranean Sea are used as a model system to examine emergent ecosystem responses to ocean acidification in rocky reef communities and suggest that a loss of biodiversity and ecosystem function is expected under extreme acidification scenarios. Expand
Ocean acidification causes ecosystem shifts via altered competitive interactions
Although calcareous species recruited and grew at similar rates to fleshy seaweeds in ambient and low pH conditions, at later stages in low pH, they were rapidly overgrown, suggesting that changes in competitive balance could indirectly lead to profound ecosystem changes in an acidified ocean.

Effects of ocean acidification on invertebrate settlement at volcanic CO2 vents
It is shown that increased levels of CO2 can profoundly affect the settlement of a wide range of benthic organisms and small crustaceans was able to settle and survive under these conditions. Expand
Depth and Seasonal Distribution of Some Groups of the Vagile Fauna of the Posidonia oceanica Leaf Stratum: Structural and Trophic Analyses
It is suggested that in the Posidonia leaf stratum, herbivores and Herbivores-deposit feeders, as consumers of epiphytic micro- and macroflora and deposited particulate organic matter, play an important role in the energy transfer from producers to higher trophic levels of the system. Expand
Adaptation and acclimatization to ocean acidification in marine ectotherms: an in situ transplant experiment with polychaetes at a shallow CO2 vent system
It is shown that a marine metazoan was able to adapt to chronic and elevated levels of pCO2, and different populations of Amphiglena mediterranea showed marked physiological plasticity indicating that adaptation or acclimatization are both viable strategies for the successful colonization of elevated p CO2 environments.

Alien species along the Italian coasts: an overview
The highest number of alien species has been observed in the northern Adriatic Sea, particularly in the Lagoon of Venice, which is the main hotspot of introduction. Expand
