Epiphytic hydroids on Posidonia oceanica seagrass meadows are winner organisms under future ocean acidification conditions: evidence from a CO 2 vent system (Ischia Island, Italy)
Effects of ocean acidification (OA) on the plant phenology and colonization/settlement pattern of the hydrozoan epibiont community of the leaves of the seagrass Posidonia oceanica have been studied at volcanic CO 2 vents off Ischia (Italy). The study was conducted in shallow Posidonia stands (2.5–3....
