Résumé
Reef-building species play key roles in promoting local species richness and regulating ecosystem functions like biogeochemical fluxes. We evaluated the functioning of a habitat engineered by the reef-building polychaete Sabellaria alveolata, by measuring oxygen and nutrient fluxes in the reef structures and in the soft-sediments nearby. Then, we investigated the relative importance of temperature, the engineer S. alveolata, and different facets of macrofauna diversity (taxonomic, functional diversity and identity), on the reef biogeochemical fluxes using multiple linear regressions and effect sizes. The reef fluxes were more intense than the soft-sediment fluxes and mainly driven by the engineer biomass and abundance, stressing the importance of these biogenic structures. Higher water temperatures and an intermediate level of associated macrofauna functional dispersion weighted only by abundance (i.e. intermediate biological trait variability) maximized the reef's global biogeochemical functioning. Ultimately, the physical degradation of the reefs could lead to lower levels of functioning.
