Settlement pattern of Posidonia oceanica epibionts along a gradient of ocean acidification: an approach with mimics
Effects of ocean acidification (OA on the colonization/settlement pattern of the epibiont community of the leaves and rhizomesof the Mediterranean seagrass,Posidoniaoceanica, have been studied at volcanic CO2vents off Ischia (Italy), using "mimics"as artificial substrates. The experiments...
