Across the world, coral reefs are currently struggling to recover from record bleaching events triggered by unusually warm ocean temperatures and a climate change-induced rise in ocean acidity. A lot of these imperilled reefs lie in the eastern Pacific region and are part of a population that, according to a new study, has been completely separated from the rest of the Pacific Ocean for at least the past two decades.
(From International Business Times / by Avaneesh Pandey)– The study, carried out by a team of researchers who used supercomputers to simulate the movement of coral larvae in the region, supports the view expressed long back by Charles Darwin, who called the over 3,100 mile stretch separating the eastern and western Pacific an “impassable” barrier.
