“…The occurrence of MEs in the Brazilian equatorial margin, in an area not under Amazon River influence, has been recently described (Almeida, Vital, & Gomes, ; Silva et al., ; Soares, Davis, Paiva, et al, ). Freitas and Lotufo (2015) described reef fishes in a mesophotic reef (36 m), and Soares, Davis, Paiva, et al. () described reef fishes and scleractinian corals at depths of 37 m. Both articles reported the presence of a mosaic of benthic habitats, composed of carbonate sediment deposits and reef outcrops located in incised shelf valleys off the Ceará state coast.…”

Aim: This study reviews recent research on the South Atlantic Mesophotic ecosystems (MEs) and the pressures threatening them, and offers suggestions for their management and conservation. Location:The South Atlantic Ocean. Methods:A comprehensive compilation of the scientific literature was performed to examine the distribution, human impacts and conservation status of the South Atlantic MEs. Results: Our review indicated that the South Atlantic Ocean (SAO) is one of the majorMEs areas in the world's oceans. The South Atlantic MEs are composed of a mosaic of distinct seascapes, mainly rhodolith beds, mesophotic reefs (i.e., rocky and biogenic) and marine animal forests (e.g., sponge aggregations, octocoral and black coral forests) that occur along the East South American and West African coasts, seamounts and oceanic islands. Throughout the SAO, the distinct seascapes of MEs are usually formed on the middle and outer continental shelves, shelf-edge, seamounts, submarine canyons, incised valleys and paleochannels, reef structures and insular shelves. We highlighted sea temperature anomalies, ocean acidification, extreme floods and droughts, fisheries, invasive species, marine debris, mining, and oil and gas exploitation as major threats to these ecosystems. Main conclusions:Given the threats to the South Atlantic MEs, growing human pressures may degrade these ecosystems in the next years and undermine their unique biodiversity as well as their potential to provide connectivity between regions and depths. Our review revealed the existence of some extensive and unprotected formations, which urgently demand in-depth investigations and conservation action.

These ecosystems are characterized by the presence of light-dependent corals and associated species (e.g.,

“…Despite a substantial increase in knowledge about Atlantic reef fish biogeography and evolution (Floeter et al., ), several areas in the SWA remained unknown and poorly studied until recently (Anderson et al., ; Freitas & Lotufo, ; Pinheiro, Joyeux, & Moura, ; Pinheiro, Mazzei et al., ). Therefore, several questions on the biogeography and evolutionary processes that shaped the reef fish fauna in the SWA are still unresolved.…”

Aim To present an updated database of fish species recorded on south‐western Atlantic reef environments and to explore the ecological drivers of the structure, the latitudinal gradient of biodiversity and the centre of endemism in this peripheral province. Location South‐western Atlantic (SWA): Brazilian and Argentinian Provinces. Methods A database composed of 733 fish species along 23 locations in the SWA (00°55′ N to 43°00′ S) was compiled based on primary data, literature and museum records. Cluster and beta diversity analyses were carried out to evaluate faunal overlaps among locations and subprovinces. “Target‐area‐distance effect” and “stepping stones dispersal” hypotheses for assemblage composition were tested through Mantel tests. Relationships between the distribution patterns and ecological traits of reef fish species were investigated through generalized linear mixed‐effect models. Results Out of the 733 fish species, 405 are SWA resident reef fishes, of which 111 (27%) are endemics and 78 are threatened with extinction. Cluster analysis detected six subprovinces in the SWA structured following the target‐area‐distance model, and with no evidence for a latitudinal gradient in diversity. The greatest overall richness and endemic species richness were found in the east–south‐eastern region. Depth range, habitat use and body size were the main drivers of SWA reef fish assemblage structure. Main conclusions The Brazilian and Argentinian coasts constitute different provinces structured by oceanographic barriers and environmental filters. Similarities among oceanic islands indicate connectivity driven by stochastic and ecological factors. Species richness and endemism indicate that peripheral provinces may also bear centres of origin and biodiversity, patterns driven by parapatric/ecological speciation and the overlap between tropical and subtropical reef fish species. Ecological drivers of reef fish distribution, such as habitat specialization and body size, support hypotheses of speciation in the periphery. New approaches for spatial planning, marine protected areas and off‐reserve marine management are essential for the conservation and sustainability of SWA reef fishes.

“…For interpretation of the biogeographic affinities of the species, analysis of the following regions in Eschmeyer and Fricke's catalog of fishes (2016) was used: WA = Western Atlantic, EA = Eastern Atlantic, CIRC = Circumtropical, and IS = Invasive species (De Freitas & Lotufo, 2014).…”

This work presents an updated taxonomic list of the fish fauna of the coral reefs in the Southeastern Reefs Marine Sanctuary (SMASE) in the Dominican Republic. The inventory is the result of 360 visual surveys of coral reefs during the period 2013-2016. We recorded 150 species from 86 genera and 47 families, including 14 new records for the southeast coastline of the Dominican Republic. The families of fishes with the highest species number comprised Serranidae (16 species), Haemulidae (12 species) and Pomacentridae (10 species).Key words: Coral reefs; Biodiversity; Caribbean; Ichthyofauna, Marine Protected Area ResumenEn este trabajo se presenta una lista taxonómica actualizada de la ictiofauna para los arrecifes de coral del Santuario Marino Arrecifes del Sureste (SMASE) en República Dominicana. El inventario es resultado de 360 censos visuales realizados en los arrecifes coralinos entre 2013 y 2016. Se incluyen 150 especies, pertenecientes a 86 géneros y 47 familias, conteniendo 14 nuevos registros para la costa sureste dominicana. Las familias de peces con mayor número de especies fueron Serranidae (16 especies), Haemulidae (12 especies) y Pomacentridae (10 especies).
