The effects of ocean acidification on the Mediterranean's biodiversity
Project description

This project consists of studying the effects of ocean acidification on a naturally acidified ecosystem. This innovative approach was used for the first time in the Mediterranean in Ischia, Italy, on a volcanic site that emitted CO2 and created a natural gradient of pH acid affecting the benthic ecosystems. The project is about the adaptive physiological response of key organisms: two common gastropods (Patella caerulea, Osilinus turbinate), a mollusk (Mitylus galloprovincialis) and a marine plant (Posidonia oceanica). Two transplantation attempts will also be carried out in situ on these organisms adapted to the acid environment, as well as studies on calcification using a 45Ca radiotracer. The results will enable us to predict more accurately the ecological consequences of sea acidification (by 2100) on the biodiversity of the benthic communities of the Mediterranean.
