“…In turn, nearshore reefs have been largely destroyed because of urbanization, chemical pollution and sedimentation (Costa et al 2008; Laborel-Deguen 2019; Fogliarini et al 2022). Furthermore, unbridled sheries activity has led to numerous stock reductions and " shing down the food web" in multiple coastal locations (Floeter et al 2006; Freire and Pauly 2010; Eggertsen et al 2024). Such regional and local impacts are largely intensi ed by global impacts associated with climate change (Halpern et al 2007; Mumby and Steneck 2008).…”

Tropical marine habitats are among the most biodiverse on Earth but are facing accelerated local and global threats. Well-planned marine protected areas (MPAs) are a countermeasure for biodiversity loss and an alternative to maintain ecosystem services and their sustainable uses. In Brazil, there is a need to improve the ecological representativeness of the national system of MPAs by incorporating poorly protected ecosystems. The Abrolhos Region and Vitoria-Trindade Seamount chain (Abrolhos Seascape) are among the biologically richest marine areas in the Southern Atlantic, and expanding the protection of key habitats in this region can help Brazil to achieve its national and international conservation goals. This study updated the habitat map and the potential distribution of 632 species of fishes, invertebrates, cetaceans, seabirds, and sea turtles, and identified priority areas for biodiversity conservation in the Abrolhos Seascape. Habitat classes were defined based on the probability of occurrence and a comprehensive updated database. Models for species distribution and the weighted endemism method, with additional weight to the threatened species, were combined to identify priority areas for biodiversity conservation. Our results indicate that although some habitats (e.g. shallow reefs, mangroves, estuaries, and deep ocean), are relatively well represented, a large portion of habitats identified as priority areas for biodiversity conservation (e.g. rhodolith beds, mesophotic reefs, shelf slopes and sinkholes), have very low or no representativeness in the current MPAs. Urgent action is needed to effectively protect these habitats, not only to conserve biodiversity, but also to maintain key ecosystem services in the region.
