Does Israel Hold the Key to Saving the World’s Coral Reefs?

While the coral reefs are dying out in most parts of the world due to the devastating effects of climate change, they appear to have adapted to the scorching temperatures of the Gulf of Eilat in southern Israel [and are] thriving—to the astonishment of the scientists.

A study published by the Journal of Experimental Biology reveals that the spawns of the fully formed corals in the Eilat waters of the northern Red Sea inherited the same genetic imprint responsible for hot weather adaptation, making the gulf one of the few places on earth where this underwater ecosystem will continue for years to come in the face of the deteriorating climate change.

The study was conducted by researchers at the laboratory of Prof. Maoz Fine of the Faculty of Life Sciences at Bar-Ilan University, as well as scientists from the Swiss Federal Institute of Technology (EPFL).

The unique aspect of Prof. Fein’s research is that it examines the impact of climate change on reproductive processes of the coral reef population, as opposed to the examination of various life stages of an adult coral.

“Although [the] world’s reefs are in a very bad state, the reefs of the northern Red Sea and particularly the Gulf of Eilat are in relatively good shape,” Fine said. “In recent studies we have tried to explain the phenomenon and found that fully formed corals are immune to high temperatures at five to six degrees [Celsius] above the summer daily maximum. This is wonderful news, because in other places the reefs turn white when the temperature rises even two degrees above the maximum.”

Fein said the reefs he had examined in his study represent the genetic imprint of the next generation of coral reefs in the region.

“This guarantees us many years of quiet, which in a way is an insurance certificate, compared to any other parts of the world, and it’s possible the coral reefs of the Gulf of Eilat will be the only ones left in the world,” he said.
