As ocean waters heat up, a quest to create super corals
2015-08-04 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: In Hawaii this summer, as corals engage in their once-a-year courtship ritual of releasing sperm and eggs into the water by moonlight, Ruth Gates will oversee a unique mating: the coming together of super-corals in her lab. Gates and her team at the Institute of Marine Biology in Kaneohe tagged corals in their local waters that thrived through a heinous hot spell last September. A few of those rugged specimens will be picked for arranged marriages this month, hopefully yielding some offspring...
Rising ocean temps bring gloomy outlook for corals
2015-07-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Beachgoers may love ocean waters that are growing balmier in a warming world, but corals, and subsequently the ecosystems they support, do not. Rising ocean temperatures are proving detrimental to both ocean species and coral reefs, with the impact on coral perhaps most noticeably seen in bleaching. On Monday, the National Oceanic and Atmospheric Administration (NOAA) released a Coral Bleaching Outlook that forecasts the amount of bleaching that may result from ocean warming in the next four months,...

Good news reefs: How corals survive a heating planet
2015-06-26 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: As concern grows over the threat coral reefs face from pollution, destructive fishing practices, and especially climate change and ocean acidification, a research team has found that heat-tolerant corals pass along that tolerance to corals adapted to cooler waters. One of the key questions regarding heat tolerance is the extent to which it is genetically inherited or whether the corals build an ability to endure heat stress through repeated exposure, a process analogous to hardening tomato plants....

Surviving harsh environments becomes death-trap specialist corals
2015-05-21 05:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The success of corals that adapt to survive in the world's hottest sea could contribute to their demise through global warming, according to new research. Researchers from the University of Southampton and the New York University Abu Dhabi found that local adaptation to high salinity levels in the southern Persian/Arabian Gulf (PAG) may prevent coral escaping their fate, as they lose their superior heat tolerance in waters with normal salinity levels. The research is published this week in...

Endangered corals smothered by sponges on overfished Caribbean reefs
2015-04-28 12:00:00| LifeSciencesWorld
[NEWS] For reef-building corals, sponges do not make good neighbors. Aggressive competitors for space, sponges use toxins, mucus, shading, and smothering to kill adjacent coral colonies and then grow on their skeletons. A recent survey of coral reefs across the Caribbean shows that overfishing removes the predators of sponges, greatly increasing the threat of fast-growing sponges to an already diminished population of corals. A research team headed by Dr. Joseph Pawlik at U…
