Coral reefs 'weathered dinosaur extinction'

Coral reefs 'weathered dinosaur extinction'

Science
Corals may have teamed up with the microscopic algae which live inside them as much as 160 million years ago, according to new research.The two organisms have a symbiotic relationship, meaning they need each other to survive.But this partnership was previously thought to have developed about 60 million years ago.The new findings suggest that reef algae may have weathered significant environmental changes over time.This includes the mass extinction that wiped out most of the dinosaurs.Algae's resilience to temperature changes has been of concern to scientists recently, as warming events on the Great Barrier Reef have seen the coral "bleached" of its algae. The study, conducted by an international ...
'Coral ticks' suck the life out of degraded coral

'Coral ticks' suck the life out of degraded coral

Science
July 26 (UPI) -- The last hope for degraded coral reefs is under attack. A new survey of Fiji Island reefs has revealed the significant damage being caused by small sea snails, previously ignored by marine biologists. Scientists have dubbed the tiny snails "coral ticks" because they suck the fluid from young Porites cylindrica coral. When researchers surveyed the impacts of coral ticks on Fiji reefs, they found snail infestations could curb Porites cylindrica growth by as much as 43 percent in a month. Until now, scientists hadn't much noticed the tiny snails. They're small, colorless and don't move around much. They don't leave obvious marks on coral, and they're mostly only found on reefs that have already been severely damaged. But even severely damaged reefs can be rehabilitated. Por...

How ocean acidification weakens coral skeletons

How ocean acidification weakens coral skeletons

Science
Jan. 29 (UPI) -- The ongoing acidification of Earth's oceans is a threat to a variety of marine organisms, including coral, the backbone of many diverse ecosystems.According to a new study published this week in the journal PNAS, acidification is curbing coral's ability to reinforce the strength of its skeleton through thickening."Our research incorporates the nuances of coral skeletal growth, enabling more precise projections of how, where, and by how much, ocean acidification will affect tropical reef-building corals," Nathaniel Mollica, an oceanography at the Woods Hole Institute in Massachusetts, said in a news release.Lab experiments attempting to measure the effects of acidification on corals have offered varied results, but the latest research suggests such confusion is a product of...
A third of coral reefs 'entangled with plastic'

A third of coral reefs 'entangled with plastic'

Science
Plastic is one of the biggest threats to the future of coral reefs after ocean warming, say scientists.More than 11 billion items of plastic were found on a third of coral reefs surveyed in the Asia-Pacific region.This figure is predicted to increase to more than 15 billion by 2025.Plastic raises by 20-fold the risk of disease outbreaks on coral reefs, according to research. Plastic bags, bottles and rice sacks were among the items found."Plastic is one of the biggest threats in the ocean at the moment, I would say, apart from climate change," said Dr Joleah Lamb of Cornell University in Ithaca, US. "It's sad how many pieces of plastic there are in the coral reefs ...if we can start targeting those big polluters of plastic, hopefully we can start reducing the amount that is going on to the...
