Seaweed fails to prevent ocean acidification impact on foraminifera along a shallow-water CO2 gradient
2015
Ocean acidification causes biodiversity loss, alters ecosystems, and may impact food security, as shells of small organisms dissolve easily in corrosive waters. There is a suggestion that photosynthetic organisms could mitigate ocean acidification on a local scale, through seagrass protection or seaweed cultivation, as net ecosystem organic production raises the saturation state of calcium carbonate making seawater less corrosive. Here, we used a natural gradient in calcium carbonate saturation, caused by shallow-water CO2 seeps in the Mediterranean Sea, to assess whether seaweed that is resistant to acidification (Padina pavonica) could prevent adverse effects of acidification on epiphytic…

Catacomba di Villagrazia di Carini. La galleria XII: indagini archeologiche e problemi della conservazione
2017
The archaeological research in the southeastern area of the Early Christian catacombs of Villagrazia di Carini has been ongoing since 2000 to the present, but in 2014 the structural problems occurred during the excavation of the cubicles X13 and X15 have showed that this sector of the cemetery was cut into a tuff stone bench less compact and durable than the rest of the catacomb. Similarly, the excavation in the corridor XII has provided new informations about the serious effects of the physico-chemical changes that occurred here, over the centuries, by the action of the environmental factors and the continued infiltrations of water from the above ground. The risk of a collapse that would m…
