1. Unravelling the foraging behavior of the southern stingray, Hypanus americanus (Myliobatiformes: Dasyatidae) in a Southwestern Atlantic MPA
RESUMO Um estudo anterior sugeriu que a raia-prego (Hypanus americanus) apresenta uma marcante mudança ontogenética no seu uso de hábitat no Arquipélago de Fernando de Noronha (FNA), local turístico atraente no Brasil, que pode ser associado a mudanças em seus hábitos alimentares e estratégias de forrageamento. Aqui, nós conduzimos amostragens visua

2. Cryptocaryon irritans, a ciliate parasite of an ornamental reef fish yellowtail tang Zebrasoma xanthurum
Resumo Cryptocaryon irritans é um protozoário ciliado parasita obrigatório de peixes marinhos selvagens e cultivados. Causa a doença dos “pontos brancos”. Infecções por esse patógeno pode causar perdas significativas para aquaristas e para marinocultura comercial em todo o mundo. Este estudo relata a ocorrência de C. irritans parasitando a espéc

3. Population dynamics of Siderastrea stellata Verrill, 1868 from Rocas Atoll, RN: implications for predicted climate change impacts at the only South Atlantic atoll
ABSTRACT Coral reefs are one of the most vulnerable ecosystems to ocean warming and acidification, and it is important to determine the role of reef building species in this environment in order to obtain insight into their susceptibility to expected impacts of global changes. Aspects of the life history of a coral population, such as reproduction, growth an

4. Organização trófica da comunidade de peixes de poças de maré da Praia dos Castelhanos (ES), Atlântico sudoeste tropical / Trophic organization of the tidepool fish community of Praia dos Castelhanos (ES), southwestern tropical Atlantic
The identification of the trophic groups is fundamental to understanding the factors responsible for organizing and structuring the communities. Accordingly, the present study was conducted in the tidepools of Praia dos Castelhanos, located in the Espírito Santo State, southeastern Brazil, in order to describe the trophic organization of the fish community,

6. Projeto raia de fogo: aspectos populacionais da raia de fogo (Dasyatis marianae Gomes, Rosa &Gadig, 2000) e pesca de elasmobrânquios no complexo recifal do Parracho de Maracajaú
The species Dasyatis marianae inhabits coastal areas associated with coral reefs, considered endemic to the northeast of Brazil, occurring from the State of Maranhão to the south of Bahia. Specimens of this species are commonly sighted by divers and fishermen in the area of Maracajaú reefs, a complex reef that is part of the Environmental Protection Area o

7. ResÃduos sÃlidos bentÃnicos em ambientes recifais de Pernambuco e na abordagem das operadoras de mergulho
Benthic marine debris are those debris deposited on the bottom of the oceans. Studies of this type of pollutant are still scarce all over the world, both about the qualiquantification, as well as about the understanding of how social actors linked to the marine environment are behaving on this issue. Thus, this study aimed to qualiquantify the benthic marine

8. Geobiologia do Atol das Rocas, Atlântico Sul Equatorial
This thesis approaches the geobiology of the only Atoll in the South Atlantic Ocean. Different classifications were made for Rocas Reef Complex along the nineteenth and twentieth century, which are evaluated historically. Biogeomorphological analysis and mapping of the reef units were done on the Rocas Atoll for the comprehension of the sedimentary dynamic a

9. Produtividade fitoplactÃnica e hidrologia no ecossistema recifal de Porto de Galinhas (Pernambuco- Brasil)
The Porto de Galinhas beach, located in the south coast of Pernambuco, Brazil, about 50 kilometers from Recife, has coral reef formations that form natural pools of extreme beauty, and thus, actually is undergoing an intense tourist activity, as one of the most visited beaches of Northeastern Brazil. The phytoplankton productivity and biomass and some hydrol

10. Ecologia trÃfica das anÃmonas-do-mar Anthopleura cascaia e Anthopleura krebsi (cnidaria: anthozoa) em duas praias de Pernambuco, Brasil
Studies of trophic ecology are fundamental to understanding the role that the species play in the ecosystem. Sea anemones are important components of reef environments, but few studies address the relationship anemone and its prey. So, it was developed a study on the species Anthopleura cascaia and Anthopleura krebsi on Piedade and Carneiros beach, in Pernam

11. Epibenthic colonization on an artificial reef in a stressed environment off the north coast of the Rio de Janeiro State, Brazil
A influência da sedimentação e da turbidez causadas pela precipitação pluviométrica e vazão do rio Paraíba do Sul nos meses de verão foi investigada em um recife artificial na costa norte do Estado do Rio de Janeiro, Brasil. Quatro placas de recrutamento e quarto placas de sucessão eram retiradas mensalmente (Janeiro de 2002 a Fevereiro de 2003) da
