  abstract = {{O}utbreaks of the coral-eating crown-of-thorns starfish {A}canthaster spp. ({COTS}) have become to be amongst the most severe threats to coral reefs worldwide. {A}lthough most research has focused on {COTS} early development, it remains unclear how {COTS} populations will keep pace with changing ocean conditions. {S}ince reproduction is a key process contributing to outbreaks, we investigated the reproductive success of adult {COTS} acclimated for 3-4 months to different treatment combinations of ambient conditions, ocean warming (+2 ?{C}) and acidification (-0.35 p{H}). {O}ur results suggest that the optimal breeding season in {N}ew {C}aledonia is concentrated around the end of the calendar year, when water temperature reaches >26 degrees {C}. {W}e found negative effects of temperature on egg metrics, fertilisation success, and {GSI}, conflicting with previously documented effects of temperature on echinoderm reproductive outputs. {F}ertilisation success dropped drastically (more than threefold) with elevated temperature during the late breeding season. {I}n contrast, we detected no effects of near-future acidification conditions on fertilisation success nor {GSI}. {T}his is the first time that {COTS} reproduction is compared among individuals acclimated to different conditions of warming and acidification. {O}ur results highlight the importance of accounting for adult exposure to better understand how {COTS} reproduction may be impacted in the face of global change.},
