Thus, today, nickel releases are common in coastal ecosystems. In this study, two major reef-building species Acropora muricata and Pocillopora damicornis were exposed in situ to ambient and moderate nickel concentrations on a short-term period (1 h) using benthic chamber experiments. Simultaneously, we tested in laboratory conditions the combined effects of a chronic exposure (8 weeks) to moderate nickel concentrations and ocean warming on A. muricata. The in situ experiment highlighted that nickel enrichment, at ambient temperature, stimulated by 27 to 47% the calcification rates of both species but not their photosynthetic performances. In contrast, an exposure to higher nickel concentration, in combination with elevated temperature simulated in aquaria, severely depressed by 30% the growth of A. muricata. specialized Metals Nickel Coral bleaching Coral photosynthesis Coral growth Global change NOUVELLE CALEDONIE 038 036 021 120 1-2 250-258 2017 0025-326X https://www.documentation.ird.fr/hor/fdi:010070917 10.1016/j.marpolbu1.2017.05.025 0025-326X [F B010070917] https://www.documentation.ird.fr/hor/fdi:010070917 https://www.documentation.ird.fr/intranet/publi/2017/09/010070917.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-10-03 2023-07-11 fdi:010070917 fre
