  abstract = {{M}adagascar is a major hotspot of biodiversity in the {W}estern {I}ndian {O}cean, but, as in many other regions, coral reefs surrounding the island confront large-scale disturbances and human-induced local stressors. {C}onservation actions have been implemented with encouraging results for fisheries, though their benefit on coral assemblages has never been rigorously addressed. {I}n this context, we analyzed the multiscale spatial variation of the composition, generic richness, abundance, life history strategies, and cover of coral assemblages among 18 stations placed at three regions around the island. {T}he potential influences of marine protected areas ({MPA}s), algal cover, substrate rugosity, herbivorous fish biomass, and geographic location were also analyzed. {O}ur results highlight the marked spatial variability, with variation at either or both regional and local scales for all coral descriptors. {T}he northeast coastal region of {M}asoala was characterized by the high abundance of coral colonies, most notably of the competitive {A}cropora and {P}ocillopora genera and stress-tolerant taxa at several stations. {T}he southwest station of {S}alary {N}ord was distinguished by lower abundances, with depauperate populations of competitive taxa. {O}n the northwest coast, {N}osy-{B}e was characterized by higher diversity and abundance as well as by high coral cover (similar to 42-70%) recorded at unfished stations. {R}esults clearly underline the positive effects of {MPA}s on all but one of the coral descriptors, particularly at {N}osy-{B}e where the highest contrast between fished and unfished stations was observed. {B}iomass of herbivorous fishes, crustose coralline algae cover, and substrate rugosity were also positively related to several coral descriptors. {T}he occurrence of reefs with high diversity, abundance, and cover of corals, including the competitive {A}cropora, is a major finding of this study. {O}ur results strongly support the implementation of locally managed marine areas with strong involvement by primary users, particularly to assist in management in countries with reduced logistic and human resources such as {M}adagascar.},
