According to a new study, some of the coral reefs in the rea are able to recover from the harmful effects of “bleaching” on corals.

A new research has shown that some there are factors that may render some reefs more resilient to the impact of catastrophic “bleaching” on corals that is caused by a rise in sea temperature. The team said that bleachingthreatensvaluable source of biodiversity as well as the tourism and fishing industries.Bleaching happens when reef symbiosis is disrupted due to a rise in seas temperature as well as several other reasons.

Nicholas Graham at Australia’s James Cook University, who is the lead researcher said, “Water depth, the physical structure of the reef before disturbance, nutrient levels, the amount of grazing by fish and survival of juvenile corals could help predict reef recovery.”

Experts said that the worst period of mass bleaching happened in 1998in 60 tropical countries due to exceptionally strong El Nino weather pattern.Corals depend on single-cell algae called dinoflagellates, who feed on nitrogen, phosphorus and other nutrients provided by the coral and they use the light to transform this food into energy.

The new study was published in the journal Nature.
