“…In this case, H. opuntia is widely distributed throughout the Caribbean and along the Brazilian coast, but the extension of its distribution reported here can cause important changes in the ecological dynamics of this single atoll formation in the south-western Atlantic, for example if these algae start to compete with corals. The sea urchin Tripneustis ventricosus (Lamarck, 1816) recently invaded the atoll probably through ballast water of ships (Soares et al, 2010) and its population has been monitored since then in order to guide proper management when and if necessary. It is alarming that H. opuntia is commonly associated with phase-shifts in the Caribbean (see Hughes, 1994), thus it is critical to understand its ecological dynamics in Rocas Atoll to determine if we are dealing with an invasive species or a natural temporal fluctuation before implementing management and removal actions.…”

Rocas is the only atoll in the south-western Atlantic and comprises a shallow platform area of about 360 km 2 , distant 230 km from the continent and 130 km from Fernando de Noronha Archipelago, in Brazil. Since the 1970s, its marine flora has received the attention of several authors, giving rise to considerable and well-established knowledge about its algal biodiversity, with a total of 143 seaweed species reported for the area. Previous efforts stressed the interesting absence of the green algae Halimeda, usually abundant in tropical reefs and one of the most important seaweed groups in the structure of the tropical benthic community. Herein, we report for the first time the presence of Halimeda opuntia at Rocas, collected during an expedition in January 2012. Based on phylogenetic analysis, was proposed that H. opuntia was originated in the Indo-Pacific Ocean and that its establishment in Brazil was independent from populations of the Caribbean as a whole and the Bahamas in particular. Another hypothesis is the current scenario of increased frequency and intensity of extreme events along the Brazilian coast, which could explain the transport of propagules from adjacent areas towards the atoll.

“…Furthermore, FNA is inserted in a Marine Protected Area (MPA), with a National Marine Park (PARNAMAR) and an Environmental Protection Area (EPA), which is classified as a UNESCO natural heritage. The RA is also inserted in an MPA, and it is situated at the top of a submarine mountain chain, with its base at 4000 m depth, located 148 km west of the Fernando de Noronha Archipelago (Soares et al, 2010).…”

“…Em linhas gerais, pode-se dizer que no Brasil os índices de eficiência da gestão de UCs costeiras e marinhas são em geral medianamente satisfatórios, como verificado na análise RAPPAM realizada com 44UCs marinhas entre os anos 2005-2011 (Ogana et al 2012) (Prates, 2003) e Parque Estadual Marinho da Pedra da Risca do Meio (Lima Filho, 2006;Soares et al 2010).…”

As áreas marinhas protegidas fazem parte de uma estratégia global de conservação da biodiversidade, uma vez que essas áreas apresentam alta riqueza biológica, sendo base para diferentes serviços ecossistêmicos. Em diversas ilhas e arquipélagos o turismo se constitui como principal atividade econômica, usufruindo dos resultados de um ambiente protegido. Porém, o turismo não controlado tornou-se a principal causa de degradação e destruição em ecossistemas insulares, sendo consequência direta de falhas na governança destes espaços. Neste contexto, o presente estudo teve como objetivo analisar a governança ambiental no Arquipélago de Fernando de Noronha (Brasil). Os dados foram coletados através de observação direta e entrevistas com atores-chave, sendo analisados pela abordagem da Policy Analysis e a partir da utilização do software MACTOR. Os resultados obtidos sugerem que, na ilha principal (a única habitada), o paraíso é substituído por graves conflitos socioambientais, caracterizados por problemas ambientais tipicamente urbanos e disputas de poder entre os atores sociais. A má gestão, a falta de integração entre as instituições e o não cumprimento às restrições ambientais podem gerar uma situação de colapso em termos sociais, ambientais e econômicos no arquipélago.
