During the "Musorstom 9" cruise in 1997, investigations of marine platforms representing drowned reef systems revealed for the first time the presence of two Acropora species as fossils at seven Marquesas islands. The predominant species was Acropora valida, which was widespread in the archipelago and dated between 7.4 and 48.6 ka, providing evidence of an earlier Pacific distribution pattern broader than previously observed. It is proposed that disappearance of Acropora after 7.4 ka was linked to climatic events probably ENSO events controlling the distribution of corals and coral reefs in the eastern Pacific without excluding alternatively the effects of an increase in sea-level rise. specialized Marquesas Acropora Fossil Climate Biogeography 021 036 30 4 1101-1105 2011 0722-4028 https://www.documentation.ird.fr/hor/fdi:010054095 10.1007/s00338-011-0810-y 0722-4028 [F B010054095] https://www.documentation.ird.fr/hor/fdi:010054095 https://www.documentation.ird.fr/intranet/publi/2011/11/010054095.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-11-30 2024-04-29 fdi:010054095 fre
