Most of the Earth's coral reefs are in very sad condition. In fact, as current climate trends continue, there is a real risk that your grandchildren will grow up in a world without coral reefs. In the waters off the coast of Hawaii, scientists have recently discovered a collection of coral that does not go down without a fight.
A recent study has documented the discovery of "super corals" that seem to have adapted to the harsh inhospitable waters of Hawaii's Canary Bay. While the battle is far from over, the marine biologists who discovered the reef state that it offers "hope for reef resilience and effective protection over the coming decades".
In the journal Proceedings of the Royal Society B: Biological Sciences, marine biologists from the University of Hawai'i found that the coral reefs of the Kane Bay were destroyed by human activity in the 1
As we have seen regularly throughout the world, this stress is sufficient to induce widespread bleaching events that are so severe that the coral reefs can not recover. In the Bay of Canada, however, many coral species appear to have achieved tolerance to the warmer waters and are recovering strongly.
To delve more deeply into this phenomenon, they took coral colonies from Kan'an Bay and another reef in Waimānalo Bay, some 18 kilometers away, and compared them to rough water under laboratory conditions claim. After living in a basin with adverse water conditions for 2.5 months, the Canary Islands Bay corals were much more resilient and grew more than twice as fast as the Waimānalo Bay coral.
This does not seem to be a short-term adjustment. "Now the question arises as to what mechanisms allow corals at these locations to exhibit increased temperature and pH tolerance, and although our experiments in the Bay of Kane seem to rule out short-term acclimatization, the mechanism remains unknown", the authors wrote in the study.
It is too early to say how often "supercorals" occur elsewhere in the world and whether they could repopulate ravaged reefs in other parts of the planet. Research shows, however, that there is still hope for the fighting reefs of the world.
"If we take the necessary steps now, we will notice that coral re-establishment in our lifetime, and our children and grandchildren will be able to observe the re-establishment of coral reefs during their time, because we make the decision Reefs are worth saving, "said study author Christopher P. Jury of the Hawai'i Institute of Marine Biology at the University of Hawai'i in Mānoa to the AFP News Agency.
