Ecologists from the University of Queensland (Australia), in a paper published in the journal PLOS Biology, said that only 3% of the reefs in the Great Barrier are fully preserved, while the rest are badly damaged.
Due to global changes in the climate, the reef began to lose corals since 1985, in the last two years, their disappearance began to progress, writes Ridus.
This is because microscopic symbionts, supplying corals with oxygen and nutrients, leave the reefs because of the temperature increase.
Interfere with corals and carnivorous starfish Acanthaster planci, attacking coral polyps.
According to scientists, 3% of healthy corals are enough to occupy almost half of the ecosystem.
But now only about 100 individual reefs correspond to the conditions under which the reef can normally develop. Researchers said that if they direct all efforts to protect these reefs, they will be able to develop fruitfully and over the course of a year they will colonize 47% of the Barrier Reef with larvae.
