“…The Mediterranean submarine volcanic vents are natural sources of CO 2 since this gas is the main component of the volcanic emissions that have been happening for hundreds of years, forming unique and extraordinary environments in which the relative abundance of dissolved inorganic carbon (Ci) species is altered by an increase in the partial pressure of CO 2 (pCO 2 ), with a consequent drastic reduction in seawater pH 1,2 . In these special acidic environments, marine ecosystems suffer from a drastic remodeling; while the pioneering studies on ocean acidification focused on how it negatively affects some species while favoring others 3 , more recent evidence exists on the large ecological effects on herbivores, invertebrates [4][5][6][7] and on intra-community processes within seagrass meadows exposed to acidic conditions 8,9 . Seagrasses have been reported to be Ci-limited in the marine realm [10][11][12] , using CO 2 and bicarbonate (HCO 3 -) as external Ci sources for photosynthesis 10 .…”

“…The pH of the water inhibited the utilization (Fragoso et al 2010). The targeted species in the present study, Hydrolithon spp had the highest coverage (18-69%; Martin et al 2008) on seagrass at a water pH of 8.1 (8.0-8.2) while there were no such epiphytes at 7.7 pH (Martin et al 2008;Mutalipassi et al 2020) owing to a positive correlation between the coralline cover and epiphytic CaCO 3 and pH (Martin et al 2008). In the Mediterranean Sea, overall the decomposition of thionitrophilous taxa reduced pH values which slowed down the growth of small calcareous species such as Pneophyllum fragile Kützing, 1843 and Hydrolithon spp which cannot grow in poor-bad conditions (Sfriso et al 2007(Sfriso et al , 2009(Sfriso et al , 2014.…”

“…Among gastropods, many herbivorous taxa can benefit from CO 2 increases at vent sites through the provision of higher habitat complexity and food, as an effect of the increase in primary production [77]. In particular, R. variabilis deserves particular mention, since this species showed sensitivity to pH reduction in laboratory trials, with alteration in its ability to perceive chemical cues from prey [78]; however, R. variabilis did not show changes in settlement along the pH gradient.…”
