Catastrophic climatic events leave corals facing a decade-long fight for recovery
Date:6/1/2013

Marine conservationists from Plymouth University, and the Universidad Federal da Bahia in Brazil, have spent more than 17 years analysing the diversity and density of coral colonies off the coast of South America.

That coincided with the catastrophic El Nio event of 1997-98, creating an opportunity for the first detailed assessment of the long-term impact a major environmental incident of this nature can have on coral assemblages.

Professor Martin Attrill, Director of Plymouth University's Marine Institute, said: "Coral reefs are perhaps the most diverse marine ecosystem on Earth, potentially holding 25% of the known marine species. Yet they are under intense threat from a range of local human activities and, in particular, climate change. Any impact on the corals is going to have major knock on effects on the organisms that live on coral reefs, such as the fish, and if climatic events become more frequent, as is suggested, it is likely corals will never be able to fully recover."

The 1997-98 El Nio was the most extensive global event of its kind in history, with record global high seawater temperatures in an 18-month period before and subsequently.

It prompted flooding in some parts of the world and droughts in others, but also caused severe coral bleaching and mortality in parts of Central America, the Indian Ocean, Arabian Gulf, the tropical Pacific and Brazil.

For this study, the research team used their own observations of eight species of scleractinian corals, and data from the Brazilian Meteorological Office, to create a full picture of environmental conditions and species behaviour that resulted.

It showed a significant rise in air and seawater temperatures in 1998, with increased mortality across all species and, in one case, it disappearing completely from the reefs for more than seven years.

The density of the coral in the area also fell after 1998, but then increased continuously until 2
