What is the "secret" of coral reef recovery in the Middle East?
Dubai, United Arab Emirates (CNN) - Although high temperatures in the water cause coral reefs to be digested or expelled, coral reefs in the Arabian Peninsula are resistant to the effects of high temperatures, Who are trying to discover the secret of their steadfastness.
The coral reefs, with their diverse colors and shapes, adorn the shallow waters around the world and serve as a refuge for diverse fish and aquatic animals. While coral reefs resemble trees or small plants, they are actually structures of living organisms called "molten or limping", which accumulate in large numbers and secrete limestone, which gives coral reefs its steel structure.
The diversity of the colors of coral reefs is due to the microscopic algae in which they live, where coral provides nutrients and a safe location to live, while coral algae provide about 90 percent of its food, making it a win-win process.
John Pert, marine biologist at New York University in Abu Dhabi, noted that rising water temperatures "drive coral reefs to digest or expel algae, leading to reduced numbers of algae and coral bleaching."
The reef, located in the Gulf of Aqaba on the northern tip of the Red Sea, is one of the areas not affected by the changes. "The rate of global warming in the Gulf is faster than the global average," said Bar-Ilan University doctoral student Jessica Bellworth. Coral reefs in those areas do not suffer from universal bleaching. "
Bill Worthy studied coral reefs in Aqaba to see how resilient they were. She began to put them in laboratories and increase the temperature by five degrees above 27 degrees Celsius. As reefs began to lose color after two or two degrees above the maximum summer temperature, Legitimate flexibility is obvious despite exposure to high temperatures.
"The sea levels were low due to the amount of water in the snow, and a sea barrier blocked the southern entrance of the Red Sea," said Professor Maher Vain, who oversaw the research on paleontology. , Which led to raising the temperature and salinity, and the death of the majority of living things.
Although the Gulf of Aqaba heat has become relatively cold, according to Fayne's theory, coral reefs have preserved their old ability to survive with warm temperatures.
On the other hand, researchers at King Abdullah University of Science and Technology in Saudi Arabia are using genetic analyzes to find out why coral reefs in the Red Sea are less susceptible to pollution, although they are not immune, compared to the same species that live on the Earth's surface and the reef barrier.
The researchers also compare individual coral reefs to determine why some reefs can tolerate more temperatures than others. The next step will be to raise coral reefs.
"Some researchers have talked about the possibility of transferring heat-resistant reefs from the southern Arabian Gulf to other parts of the world, but we do not know the genetic effects, and there is a risk of introduction of the disease and parasites," Burt said.
