  abstract = {{I}ncreasingly frequent and severe bleaching events driven by climate change are decreasing coral populations worldwide. {R}ecovery of these populations relies on reproduction by the survivors of such events including local and upstream larval sources. {Y}et, corals that survive bleaching may be impaired by sublethal effects that suppress reproduction, reducing larval input to reefs, and consequently impeding recovery. {W}e investigated the impact of the 2020 mass-bleaching event on {A}cropora millepora reproduction on inshore, turbid reefs in {W}oppaburra sea {C}ountry (the {K}eppel {I}slands), to improve our understanding of the effects of bleaching on coral populations. {A}. millepora experienced high bleaching incidence but low mortality across the island group during this event and thus constituted an ideal population to investigate potential sublethal effects on reproductive output. {S}ix months after the heat wave, and just prior to spawning, we collected, decalcified, and dissected samples from 94 tagged {A}. millepora colonies with a known 2020 bleaching response, to investigate the relationships between stress severity and reproduction. {D}espite having regained their pigmentation, we detected a significant reduction in fecundity in colonies that had bleached severely. {C}onsidering the impact of the bleaching event on the coral population sampled (i.e., mortality, bleaching severity and colony size), coupled with reductions in fecundity, we estimated a total decrease in population-level reproductive output of 21%. {T}hese results suggest that reduced reproductive output may impact recovery of coral populations following bleaching and should be considered alongside traditional estimates of coral mortality.},
