We analyzed the density of juvenile and adult corals among 18 stations located at three regions around Madagascar, and examined the effects of Marine Protected Areas (MPAs). Our survey did not detect a positive effect of MPAs on juveniles, except for Porites at the study scale. The MPA effect was more pronounced for adults, notably for Acropora, Montipora, Seriatopora, and Porites at the regional scale. For most dominant genera, densities of ju-veniles and adults were positively correlated at the study scale, and at least at one of the three regions. These outcomes suggest recruitment-limitation relationships for several coral taxa, although differences in post -settlement events may be sufficiently strong to distort the pattern established at settlement for other pop-ulations. The modest benefits of MPAs on the density of juvenile corals demonstrated here argue in favor of strengthening conservation measures more specifically focused to protect recruitment processes. specialized Coral assemblages Spatial patterns Marine protected areas Recruitment process Population regulation Madagascar MADAGASCAR 034 082 040 190 106080 [11 ] 2023 0141-1136 https://www.documentation.ird.fr/hor/fdi:010088308 10.1016/j.marenvres.2023.106080 0141-1136 [F B010088308] https://www.documentation.ird.fr/hor/fdi:010088308 https://www.documentation.ird.fr/intranet/publi/2023-09/010088308.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-09-22 2025-02-24 fdi:010088308 fre
