BRANQUEAMENTO DOS CORAIS PDF
ARTIGOS. Branqueamento de corais nos recifes da Bahia e sua relação com eventos de anomalias térmicas nas águas superficiais do oceano. Coral bleaching. Over the last month, newspapers have been flooded with information about coral bleaching – what is great to raise global awareness about this very serious. A new study confirms that coral reefs have faced devastating damage in recent years—a symptom of Earth’s rapidly changing climate.

Coral bleaching in Bahia reefs and its relation with sea surface temperature anomalies.
Mussismilia hispida, Siderastrea spp. Since several coral bleaching events were registered in Bahia. There were no mass coral death associated to these events and the affected corals fully recovered after the impact.
From to anomalies of 0. However in the Abrolhos region, where reefs are located more than 10 km from the continent, only SST anomalies higher than 0. All species presented different levels of bleaching, ‘light’ or ‘heavy’. In Bahia, there is a strong linkage between coral bleaching and periods of elevated sea surface temperature, and the most affected corals were the ones from the coastal reefs.
These coastal reefs are exposed to the impacts from processes occurring in the continent, suggesting that corals exposed to high levels of nutrient and sediment loads, and brsnqueamento SST fluctuations, may be more resistant to the post bleaching effects, such as infectious diseases and mass mortality.
