“…5) is in accordance with the hard coral coverage evaluated by Ferreira et al (2012). They reported a higher percentage in the open pools compared to the isolated ones: 50.6±6.0% at Salão; 34.0 ±14.2% at Podes Crer; followed by 22.5±7.8% in Tartarugas and the lowest coverage, 5.6 ±6.1% at Cemitério.…”

“…Local scale anthropogenic stressors, such as accelerated coastal development, reef eutrophication, marine pollution, tourism pressure, over-exploitation of reef resources, overfishing and destructive fisheries and, more recently, the introduction of nonindigenous invasive species are also related to this degradation (Leão and Kikuchi 2011). There is a record of the impact of ENSO events in the coral community at the atoll (Ferreira et al 2012) but overall, the differences in the linear extension rates for S. stellata we observed in this study may reflect the higher environmental quality of the reef system in Rocas compared to those from Bahia.…”

“…This would explain the higher frequency of juvenile colonies in the closed pools, where we observed frequencies of 67.4% at Porites and 62.3% at Âncoras in colonies with 4.1 to 10 cm diameters. Ferreira et al (2012) indicate that the occurrence of two sequential positive SST anomalies (2009 and 2010), which triggered up to 50% coral bleaching in the Rocas Atoll and Fernando de Noronha reefs, reduced post-bleaching coral recovery and intensified the outbreak of diseases, specifically black-band, plague and darkspot diseases affecting primarily Siderastrea spp. at the atoll.…”

“…BARBARA R. PINHEIRO et al equatorial location of the Rocas Atoll leads to minimal seasonal SST variability, with an annual range of 3°C for monthly mean temperatures (Ferreira et al 2012). Salinity in the surrounding seawaters varies from 36 to 37 parts per thousand (ppt) (Gherardi and Bosence 1999).…”

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 and size-frequency can contribute to the production of models that are used to estimate impacts and potential recovery of the population, acting as a powerful tool for the conservation and management of those ecosystems. Here, we present the first evidence of Siderastrea stellata planulation, its early growth, population size-frequency distribution and growth rate of adult colonies in Rocas Atoll. Our results, together with the environmental protection policies and the absence of anthropogenic pressures, suggest that S. stellata population may have a good potential in the maintenance and recovery in the atoll. However, our results also indicate an impact on corals' recruitment, probably as a consequence of the positive temperature anomaly that occurred in 2010. Thus, despite the pristine status of Rocas Atoll, the preservation of its coral community seems to be threatened by current global changes, such as more frequent thermal stress events.
