“…There was a notable presence of species of the families Haemulidae, Lutjanidae, Acanthuridae, Pomacentridae and Holocentridae at all four study reefs, a result very similar to that observed in other reef areas in north‐eastern Brazil (Rocha et al , 1998; Feitoza, 2001; Rocha & Rosa, 2001; Kikuchi et al , 2003; Engmann, 2006). The family Haemulidae was quite abundant on the Cabeço dos Cangulos Reef, although in smaller proportions than observed near the artificial reef environments surveyed here.…”

“…The coral reefs along the Brazilian coast stretch for c. 3000 km from Maranhão (0° 50′ S) to southern Bahia (19° 0′ S) (Kikuchi et al , 2003). These ecosystems are considered ecologically unique as they were constructed in large part by calcareous algae (associated with corals and other organisms) and are significantly different from the better known coral reefs found throughout most tropical seas.…”

The composition and trophic structure of reef fish communities in two natural and two artificial reefs along the coast of Paraíba State in north-eastern Brazil were investigated. A total of 114 species of fish belonging to 47 families were recorded during 120 stationary visual surveys, slightly less than half (46·55%) of which were recorded at all four surveyed localities. Most species are widely distributed on the western Atlantic coast, but several are endemic to Brazil. The greatest diversity and equitability indexes were recorded at the reefs of Sapatas and Cabeço dos Cangulos, whereas the greatest richness and abundance were found at the Queimado shipwreck. The Alvarenga shipwreck reef had the least richness, diversity and equitability. The four localities studied had very similar ichthyofaunas, especially in relation to species composition. The reefs along the Paraíba coast are considered priority conservation areas by the Brazilian Ministry of the Environment, and the information generated by this study will be useful for comparison with other reefs in the region and can be directly applied to programmes seeking to protect and manage these environments.

“…The sites in Abrolhos Archipelago with the lowest vital indices are those where tourism are more intense. Previous analysis on 2000 surveys (Kikuchi et al 2003a) and 2002(Spanó et al 2008 had already shown this. The offshore reefs data display a difference on surveys from 2000 to 2002; however, this difference might rather be the result of inter-annual variability, than change in the ecological conditions.…”

<span>Desde el año 2000 se inició un programa de monitoreo utilizando el protocolo AGRRA en el Parque Nacional Marino de Abrolhos en el marco de la creación del Nodo STA de la GCRMN. Entre 2000 y 2005 se realizaron varias evaluaciones en 26 arrecifes. Los patrones espaciales y temporales de la vitalidad de los arrecifes fueron estudiados mediante análisis de ordenación (MDS), similaridad (ANOSIM) y porcentajes de similaridad (SIMPER). La cobertura de coral vivo, la densidad de colonias grandes (>20cm) y de reclutas (<2cm) y la cobertura de macroalgas indicaron que los arrecifes ubicados a más de 5km de la costa presentan una mejor condición que aquellos ubicados a menos de 5km de la costa. Los arrecifes más alejados registraron una mayor densidad de colonias, un bajo índice de macroalgas, un relativo más alto porcentaje de coberturas algales y una más alta densidad de reclutas en comparación con los arrecifes más cercanos. Los arrecifes más cercanos a la costa han sido más severamente afectados por las actividades humanas. Por ejemplo, eutrofización de aguas (contaminación de aguas residuales), mayor sedimentación y turbidez del agua, mal uso de los arrecifes y sobreexplotación de sus recursos. La implementación de un programa integral de monitoreo en Bahia es urgente y obligatorio para mejorar las estrategias de protección y los esfuerzos de manejo de sus arrecifes.</span>

“…Thermal anomalies on the Brazilian coast have been monitored by NOAA satellite imaging since 1998, and there have been many reports of bleaching events occurring in association with ocean warming events (Migotto, 1997;Castro & Pires, 1999;Dutra et al, 2000;Costa et al, 2001Costa et al, , 2004Costa & Amaral, 2002;Kikuchi et al, 2003;Leão et al, 2003Leão et al, , 2008Ferreira & Maida, 2006). None-theless, only Dutra et al (2000), reported observations of the reefs after the occurrence of the bleaching phenomenon.…”

Episodes of coral bleaching related to El Niño events have been increasing in frequency and severity. This phenomenon is cited as a major cause of degradation of coral reefs. This study evaluates the effects of coral bleaching on the Caramuanas reef community, which occurred during the southern hemisphere summer of 2009/2010. Within this period the sea surface temperature of 31°C and thermal anomalies up to almost 1°C were recorded. During and after this El Niño event, frequency and severity of bleaching, live coral cover, number of colonies, class size, disease occurrence, and mortality rate were monitored on corals larger than 20 cm in diameter. The samples were taken at twelve fixed transects, in three reef stations. Statistical analysis showed that the severity of bleaching was different between the two periods, during and after the 2010 ENSO event. The Caramuanas reef showed sublethal bleaching effects indicating that this reef is tolerant to bleaching when the temperature anomalies do not exceed 0.75°C within one week.
