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

The Abrolhos Bank is an area of high ecological, socio-economic importance and harbour the richest and most-extensive coral reefs in the South Atlantic. During 14 expeditions from late 2013 to late 2015 on the central/southern coast of the Espírito Santo State (19°–20° S)  we have discovered  the existence of a series of new shallow (12–25 m depth) reef complex with  large biogenic structures, intermediate between the typical mushroom-shaped pinnacles of the northern Abrolhos Bank (17°–18° S) and the common small patch reefs. 

These newly discovered reefs harbour a relatively rich and abundant reef community, with 73 fish and 14 benthic cnidarian species to date, including endangered and commercially important ones. Importantly, the area urgently needs a properly mapping and understanding the ecological functioning of this reef system. Information provided in the article published at the Marine Pollution Bulletin "Newly discovered reefs in the southern Abrolhos Bank, Brazil: Anthropogenic impacts and urgent conservation needs (https://t.co/3eNdLdNqWw)"  is a baseline for future impact evaluations, particularly considering the recent worst environmental disaster of Brazil from a dam collapse in Doce river that affected the region.

O Banco dos Abrolhos é uma rica área em termos ecológicos e sócio-econômicos, a qual abriga a mais ampla riqueza recifal no oceano Atlântico Sul. Ao longo de 14 expedições do fim de 2013 ao fim de 2015 na região central/sul do estado do Espírito Santo (19°–20° S) nós descobrimos a existência de uma série de novos recifes rasos (12-25m de profundidade) com amplas estruturas biogênicas e formatos intermediários entre os famosos chapeirões do norte do banco dos Abrolhos (17°–18° S) e os recifes em mancha, comuns na região. 

Estes recifes recém descobertos abrigam uma rica e abundante fauna recifal, que conta até o momento com 73 espécies de peixes e 14 cnidários bentônicos, incluindo espécies ameaçadas e de importância econômica. Cabe ressaltar que a área necessita de um mapeamento urgente, além de pesquisas para compreender melhor o papel desses recifes. As informações contidas no artigo publicado no Marine Pollution Bulletin "Newly discovered reefs in the southern Abrolhos Bank, Brazil: Anthropogenic impacts and urgent conservation needs (https://t.co/3eNdLdNqWw)" configuram uma primeira base de conhecimento para futuras avaliações de impacto na região, considerando em particular o pior e mais recente desastre ambiental  no Brasil, com o rompimento da barreira no Rio Doce, o qual afetou o região.
