Default Why Coral Reefs Around The World Are Collapsing

Why Coral Reefs Around The World Are Collapsing
ScienceDaily (May 29, 2009) — An explosion of knowledge has been made in the last few years about the basic biology of corals, researchers say in a new report, helping to explain why coral reefs around the world are collapsing and what it will take for them to survive a gauntlet of climate change and ocean acidification.

Why Coral Reefs Around The World Are Collapsing
excerpt from above:
Quote:
Corals, it appears, have a genetic complexity that rivals that of humans, have sophisticated systems of biological communication that are being stressed by global change, and are only able to survive based on proper function of an intricate symbiotic relationship with algae that live within their bodies.

After being a highly successful life form for 250 million years, disruptions in these biological and communication systems are the underlying cause of the coral bleaching and collapse of coral reef ecosystems around the world, scientists report in the journal Science.

Default Coral Reefs Face Increasing Difficulties Recovering From Storm Damage

Coral Reefs Face Increasing Difficulties Recovering From Storm Damage

ScienceDaily (Aug. 4, 2009) — As global warming whips up more powerful and frequent hurricanes and storms, the world’s coral reefs face increased disruption to their ability to breed and recover from damage.

Coral Reefs Face Increasing Difficulties Recovering From Storm Damage
excerpt from above:
Quote:
“We have found clear evidence that coral recruitment – the regrowth of young corals – drops sharply in the wake of a major bleaching event or a hurricane,” says lead author Dr Jennie Mallela of the ARC Centre of Excellence for Coral Reef Studies and Australian National University.

I thought this interesting.
Quote:
"Some of these algae that live within corals are amazingly productive, and in some cases give 95 percent of the sugars they produce to the coral to use for energy," Weis said. "In return the algae gain nitrogen, a limiting nutrient in the ocean, by feeding off the waste from the coral. It's a finely developed symbiotic relationship."

Climate change and coral reefs: Coral species has developed the 'skills' to cope with rising temperatures

Move, adapt or die. Those are the options marine plants and animals have in the face of climate change, said Stanford biologist Steve Palumbi, who has been exploring how to help them go with the first two options, rather than the third. He's come up with some surprising answers...

excerpt from above:
Quote:
Corals around the world, already threatened by pollution, destructive fishing practices and other problems, are also widely regarded as among the ecosystems likely to be first — and most — threatened with destruction as earth’s climate warms.

But there is reason to hope, researchers are reporting. The scientists, from Penn State University and elsewhere, have produced new evidence that...

Corals can survive the early stages of their development even under the tough conditions that rising carbon emissions will impose on them says a new study from the ARC Centre of Excellence for Coral Reef Studies.

Globally, ocean acidification remains a major concern and scientists say it could have severe consequences for the health of adult corals, however, the evidence for negative effects on the early life stages of corals is less clear cut...
