  abstract = {{C}oral reefs are iconic ecosystems with immense ecological, economic and cultural value, but globally their carbonate-based skeletal construction is threatened by ocean acidification ({OA}). {I}dentifying coral species that have specialised mechanisms to maintain high rates of calcification in the face of declining seawater p{H} is of paramount importance in predicting future species composition, and growth of coral reefs. {H}ere, we studied multiple coral species from two distinct volcanic {CO}2 seeps in {P}apua {N}ew {G}uinea to assess their capacity to control their calcifying fluid ({CF}) chemistry. {S}everal coral species living under conditions of low mean seawater p{H}, but with either low or high variability in seawater p{H}, were examined and compared with those living in 'normal' (non-seep) ambient seawater p{H}. {W}e show that when mean seawater p{H} is low but highly variable, corals have a greater ability to maintain constant p{H}(cf) in their {CF}, but this characteristic was not linked with changes in abundance. {W}ithin less variable low p{H} seawater, corals with limited reductions in p{H}(cf) at the seep sites compared with controls tended to be more abundant at the seep site than at the control site. {H}owever, this finding was strongly influenced by a single species ({M}ontipora foliosa), which was able to maintain complete p{H}(cf) homeostasis. {O}verall, although our findings indicate that there might be an association between ecological success and greater p{H}(cf) homeostasis, further research with additional species and at more sites with differing seawater p{H} regimes is required to solidify inferences regarding coral ecological success under future {OA}.},
