The El Niño, in itself, is an event that concerns a large fringe of the community affected by him, from South America to Asia. Now, at a time he is back, there is another community which provides devastating effects to the area which studies, marine biology.According to scientists who are analyzing the phenomenon, a major El Niño event can negatively impact coral reefs around the world. The last major phenomenon, which lasted between 1997 and 1998, caused the worst coral bleaching in history. In total, 16% of these were destroyed â€" in the case of Maldives, the percentage reached some unthinkable 90%.According to the Australian Bureau of meteorology, there is a chance of occurrence of the phenomenon this year, and the signs are not positive. It can be worse than 1998, which means a problem for industry and global agriculture, but also for the so-called Coral triangle, a region in Southeast Asia which houses more marine species than any other place on the planet."In 1998, the Coral triangle began to whiten in may, and this happened until September," explained this Friday Ove Hoeg Guldberg, a marine biologist at the Institute for Global change at the University of Queensland. "The region has extended periods of temperature anomalies during El Nino because the Equator passes through the middle of it, and therefore the area experiences both the Summer in the northern hemisphere and the South."Guldberg, who heads the chapter on oceans of the report of the Intergovernmental Panel of climate science (IPCC) says that it only required half a degree more than temperature at sea for bleaching of corals.Corals are animals that behave like plants, maintaining a symbiotic relationship with the dinoflagellates, a type of microbe that live within their tissues, where do photosynthesis and sugar to its host.But as temperatures rise, the dinoflagellates stop producing sugar and instead produce dangerous free radicals. The corals expel us, stop producing its coverage of calcium carbonate and turn white, explains the Climate Central.See a gallery of algae and corals recently discovered in northwest of Hawaii.Foto:  Derek Keats / Creative Commons.fancybox-wrap { position: absolute; top:0; left: 0; z-index: 8020; } .fancybox-skin { position: relative; /*margin-top:20px !important;*/ background: #222222; color: #74b32e; text-shadow: none; -webkit-border-radius: 2px; -moz-border-radius: 2px; border-radius: 2px; } .fancybox-opened { z-index: 8030; } .fancybox-opened .fancybox-skin { -webkit-box-shadow: 0 10px 25px rgba(0, 0, 0, 0.5); -moz-box-shadow: 0 10px 25px rgba(0, 0, 0, 0.5); box-shadow: 0 10px 25px rgba(0, 0, 0, 0.5); } .fancybox-outer, .fancybox-inner { position: relative; } .fancybox-inner { overflow: hidden; } .fancybox-type-iframe .fancybox-inner { -webkit-overflow-scrolling: touch; } .fancybox-close{ background: url('wp-content/themes/codistage/styles/fancybox/exit.png') no-repeat; width:25px; height:25px; float:right; margin-top:10px; margin-right:5px; } /*.ngg-gallery-image img{width:565px; height:393px;}*/Os recifes de corais estão em perigo1of 17jQuery(document).ready(function($) { var thumbContainerWidth = 0, thumbs = Array(), selectedIndex = 1, thumbIndex = 1, imageOffset = 7; $('.ngg-gallery-thumbnail-box').each(function() { thumbs.push($(this)); }); /*thumbnail navigation */ $('.ngg-greensavers-thumb-next').unbind().bind('click', function(e) { e.preventDefault(); if(thumbIndex<= (thumbs.length-imageOffset)) { $('.ngg-thumbnails-container').stop().animate({ left : -$(thumbs[thumbIndex]).position().left }); thumbIndex++; } }); $('.ngg-greensavers-thumb-prev').unbind().bind('click', function(e) { e.preventDefault(); if(thumbIndex >1) { $('.ngg-thumbnails-container').stop().animate({ left : $('.ngg-thumbnails-container').position().left + ( $(thumbs[thumbIndex-1]).position().left - $(thumbs[thumbIndex-2]).position().left ) }); thumbIndex--; } }); $(window).load(function() { /* set thumbnail container width */ $('.ngg-gallery-thumbnail').each(function() { thumbContainerWidth = thumbContainerWidth + $(this).width() + 10; }); $('.ngg-thumbnails-container').width(thumbContainerWidth); }); });
