mortality (due to bleaching) was higher than rate of bleaching (Leptoseris gardineri). Coral bleaching occurs when coral polyps expel algae that live inside their tissues. This photo taken on March 2020 shows coral bleaching on the Great Barrier Reef in Australia. At our GBR sites, coral taxa Porites, Leptoseris, Acropora and Pocillopora showed a comparatively low chance of experiencing bleaching and mortality, whereas taxa such as Stylophora, Isopora and Montipora were particularly prone to bleaching (see Fig. Coral can survive a bleaching but being bleached puts coral at higher risk for disease and death. ... A specimen of Leptoseris troglodyta, the cave-dwelling coral, photographed near Indonesia in 2003. The 1998 bleaching event reduced coral species richness by 61% and reduced coral cover by 85%. Normally, coral polyps live in an endosymbiotic relationship with these algae, which are crucial for the health of the coral and the reef. Four more severe bleaching events have occurred since, in 2002, 2016, 2017, and now in 2020. “By being active in … For the best experience on our site, be sure to turn on Javascript in your browser.

Bleaching is associated with the devastation of coral reefs, which are home to approximately 25 percent of all marine species. Three specimens of the coral Leptoseris kalayaanensis Licuanan and Aliño, 2009 (Scleractinia: Agariciidae) were discovered (15 m depth) in the Kalaayan Is. In our experience, Leptoseris is a challenging coral to feed and most attempts up to this point have been unsuccessful. Two earlier mass bleaching events occurred on the Great Barrier Reef in 1998 and 2002, that were less severe than 2016. The scientists' main concern this year is the southern region, which escaped the bleaching during 2016 and 2017 as water temperatures were close to normal, Hughes said. Having said that, Leptoseris are highly adaptable to different lighting systems but do change colors to compensate. There is a need to rapidly mobilize a team to respond to the coral bleaching event that is currently underway in Puerto Rico and the USVI. They are also source of food security for millions of people around the world. Bleaching is when corals turn white as a stress response to warm water temperatures. Coral reefs protect coastlines by absorbing constant wave energy from the ocean, thereby protecting people living near the coast from increased storm damage, erosion and flooding. What is amazing about them, they exist without the symbiotic algea and dwells in holes, at the ceiling of caves, where almost no light occurs. No more waiting in all day.
