The primary consequence of global warming for reefs is coral bleaching, often leading to extensive mortality. Although bleaching well-documented globally, the thermal stress and experienced by unique South Atlantic remain largely unknown due insufficient monitoring on both spatial temporal scales. Therefore, this work aimed reconstruct past episodes across reefs, assessed whether are becoming more intense, longer-lasting, frequent. We retrieved daily 5 km-resolution Degree Heating Week (DHW) data from U.S. National Oceanic Atmospheric Administration Coral Reef Watch server 33 reef sites spanning last 40 years. For each episode, we intensity (maximum DHW value), duration (number continuous days under stress), frequency between episodes). Generalized linear models were fitted intensity, duration, evaluate influence latitude time x region interaction as predictors. recorded multiple episodes, increasing 2010 onwards, ranging 10 1985-89 75 2020-24. Intensity increased over entire Atlantic. Frequency also Southwestern coast oceanic islands, but not Africa. Episodes at higher latitudes prolonged, validity history reconstruction was groundtruthed using information Abrolhos Bank, only consistently monitored site in Atlantic-DHW accurately matched observed site. With this, our dataset shows that likely occurred Atlantic, went undocumented field. currently available underestimates extent occurring area, which experiencing increases stress.

Remote sensing monitoring and geomorphologic change analysis of coral reefs are great practical significance for the ecological protection sustainable development reef area resources. A WBMD scheme is proposed to better extract information from island environments Xisha, China. Satellite imagery, after preprocessing, subjected water depth correction mitigate influence on reflectance. maximum likelihood classification model then used geomorphological classification, followed by refinement through a decision tree model, forming scheme. The overall accuracy Xisha Chau Zhaoshu Island based was 97.07% 95.07%. Using this analyze geomorphology 2014 2018 reveals that degradation mainly distributed in lagoon slope around lagoon, has been shrinking year year, while gray sand increased, areas other types exhibit fluctuating changes. Previous studies have indicated area, where significant also observed, raising an alarm conservation efforts

Corals can be considered holobiont organisms, since they have an important symbiotic relationship with microbial communities such as zooxanthellae, bacteria, Archaea, fungi and viruses. It is to understand how those influence the health of corals environmental conditions could affect them. The present study aimed describe bacterial associated three Brazilian coral species, Millepora alcicornis, Mussismilia harttii Phyllogorgia dilatata, by a culture-independent method, using 16S rRNA gene sequencing. were collected from two distinct reefs: Recife de Fora, in Bahia (BA) Búzios, Rio Janeiro (RJ). phylum Proteobacteria showed highest relative abundance most sites. compositions these sample sites very each other, not presenting similarities species or related sampling site. In M. alcicornes/RJ, abundant class was Gammaproteobacteria, order Piscirickettsiales, while same BA unassigned Vibrionaceae second family. harttii/BA presented composition 16 phyla (26% Proteobacteria, 16% Chloroflexi, 12% Acidobacteriota).
