Newly discovered reefs in the southern Abrolhos Bank, Brazil: Anthropogenic impacts and urgent conservation needs

“…This region corresponds to an ecological and biogeographic transitional zone between tropical and subtropical marine biotas (Lavrado and Ignacio, 2006;Spalding et al, 2007;Pinheiro et al, 2015b), characterized by the occurrence of range boundaries of multiple species (Andreata and Séret, 1995;Absalão et al, 2006;Paiva, 2006;Serejo et al, 2006). Despite recent mapping surveys across the Abrolhos Bank, the area of the unexplored shallow reefs complex described here was assigned as unconsolidated sediments (see Fig.…”

The shore fishes of the Trindade–Martin Vaz insular complex: an update

“…Prior to the present work, collections and observations of shore fishes were made by Murray (); Nichols & Murphy (); Miranda‐Ribeiro (); Carvalho () and Gasparini & Floeter () in Trindade; and by Andreata & Séret (); Pinheiro et al . () and Pereira‐Filho et al .…”

“…Scorpaena albifimbria represents an interesting discovery because the species was only known from the north‐western Atlantic Ocean (Froese & Pauly, ). Monopenchelys acuta , on the other hand, is present in all tropical oceans (Froese & Pauly, ) but its only previous record in the Brazilian province is on the Vitória–Trindade Chain (Andreata & Séret, ). Individuals of Emblemariopsis aff.…”

“…The presence in Trindade of the cobalt chromis Chromis flavicauda (Günther 1880), collected in Martin Vaz by Andreata & Séret (1995) but equivocally cited for Trindade by Gasparini & Floeter (2001), is here confirmed. Another species previously known only for Martin Vaz, the Atlantic cornetfish Aulostomus strigosus Wheeler 1955 (Pinheiro et al ., 2009), was also collected in Trindade.…”

“…1(f)]. The clinid Ribeiroclinus eigenmanni (Jordan 1888) cited by Gasparini & Floeter (2001) for Trindade was caught on the Vitória-Trindade Chain (Columbia seamount) by Andreata & Séret (1995). To date, no specimen of this species has been caught or sighted at either Trindade or Martin Vaz.…”
