  "description": "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 were conducted in shallowPosidoniastands (2-3 m depth), in three stations on the northand  three on the south sides of the study area, distributed along a pH  gradient. At each station, 4 rhizome mimics and 6 artificialleaves were collected every three months (Sept 2009-Sept 2010). The epibionts on both leaf and rhizome mimics showed clearchanges  along the pH gradient; coralline algae and calcareous invertebrates  (bryozoans, serpulid polychaetes and barnacles) weredominant at control stations but progressively disappeared at the most acidified stations. In these extremely low pH sites theassemblage was dominated by filamentous algae and non calcareous taxa such as hydroids and tunicates. Settlement pattern onthe  artificial leaves and rhizome mimics over time showed a consistent  distribution pattern along the pH gradient and highlightedthe  peak  of  recruitment  of  the  various  organisms  in  different  periods  according  to  their  life  history.Posidoniamimics  at  theacidified  station showed a poor and very simplified assemblage where calcifying  epibionts seemed less competitive for space. Thisprofound difference in epiphyte communities in low pH conditions suggests cascading effects on the food web of the meadow and,consequently, on the functioning of the system",
