It's All About Being Fat And Flexible For Corals Adapting To Climate Change
2014-07-10 03:47:46

By Pam Frost Gorder, Ohio State University Study suggests best targets for environmental conservation The future health of the world's coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat—and to be flexible about the type of algae it cooperates with. In the first study of its kind, scientists at The Ohio State University discovered that corals—tiny reef-forming animals that live symbiotically with algae—are...

Scientists Working To Protect Australia's Great Barrier Reef
2014-07-03 14:37:23

Brett Smith for redOrbit.com - Your Universe Online Australian scientists are studying degraded reefs off the Northwest Australian coast as the country marks a decade since a massive rezoning of the Great Barrier Reef Marine Park. “Reefs north of Exmouth have experienced large-scale bleaching in the past five years,” said Malcolm McCulloch from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at the University of Western Australia. The marine biology team is busy...

More Coral Babies Staying At Home On Future Reefs

Nova Southeastern University It seems that coral reefs are experiencing something their human counterparts have been for years – a shrinking "empty nest" syndrome. That's right – researchers have found that increasing ocean temperatures due to climate change will soon see reefs retaining and nurturing more of their own coral larvae, leaving large reef systems less interconnected. The study brought together an international group of researchers from NSU's Oceanographic Center; the...

Marine Pollution Impact On Corals Is Harsh, But They Can Recover
2013-11-26 14:24:00

[ Watch the Video: Protection From Marine Pollution Would Help Coral Reefs Recover ] Brett Smith for redOrbit.com - Your Universe Online A new study on coral reefs from a team of Florida and Oregon researchers has found common marine pollution doubled the rate of disease among corals and more than tripled the amount of coral bleaching, an early sign of reef stress. According to the team’s report in Global Change Biology, a three-year, controlled exposure of corals to high levels of...

Coral Recovery In Light Of Cyclone Yasi Shows Promise
2013-06-07 08:52:34

April Flowers for redOrbit.com - Your Universe Online The coral reefs on Australia´s Great Barrier Reef were devastated by Cyclone Yasi — a Category 5 Hurricane which made landfall in Queensland, Australia, on February 3, 2011. A new study from the ARC Center of Excellence for Coral Reef Studies (CoECRS) shows that large numbers of coral larvae replenished the reefs within nine months of the cyclone. The findings, published in PLoS ONE, provide fresh hope for the ability of...

Microborers Represent New Threat To Earth’s Coral Reefs
2013-03-18 11:42:49

Brett Smith for redOrbit.com - Your Universe Online Previous studies have shown that warming oceans and ocean acidification threaten to destroy the ocean´s coral reefs. Now, a new study from Australian researchers published in the journal Global Change Biology suggests that yet another threat could decimate these delicate ecosystems. “Our research shows that when seawater is both acidic and warm — which is predicted to happen under future climate scenarios — coral...

Using a world-first scientific discovery, Australian researchers are developing a stress-test for coral, to measure how coral reefs are being impacted by pressures from climate change and human activity. The scientists have found hemoglobin genes in the microalgae which live symbiotically with coral, which may provide a readout on how stressed a particular coral is — and how likely it is to bleach and die. Coral bleaching occurs when the symbiotic algae abandon the coral due to...

Investigating How Corals Survive In The Hottest Reefs On The Planet
2013-02-01 14:48:45

National Oceanography Centre, Southampton (UK) Coral reefs are predicted to decline under the pressure of global warming. However, a number of coral species can survive at seawater temperatures even higher than predicted for the tropics during the next century. How they survive, while most species cannot, is being investigated by researchers at the National Oceanography Centre, Southampton (NOCS) and New York University Abu Dhabi (NYUAD). We tend to associate coral reefs with tropical...

European Settlement Caused Collapse Of Great Barrier Reef Coral
2012-11-07 10:07:33

Lawrence LeBlond for redOrbit.com - Your Universe Online Australia´s Great Barrier Reef, the largest coral system in the world, so big that it can be seen from space, is one of the planet´s most remarkable natural wonders. But researchers from University of Queensland have now revealed this precious ecosystem is not faring so well. The problem: European settlement and extensive degradation on mainland Australia. The expansion of European settlement in Australia has been...

Great Barrier Reef Is Shrinking
2012-10-02 07:58:43

April Flowers for redOrbit.com - Your Universe Online The Great Barrier Reef in Australia is the world's largest coral reef, and the only living thing on Earth that is visible from space. The Great Barrier Reef is approximately 3000 kilometers long and up to 65 kilometers wide in some places. According to new research from the Australian Institute of Marine Science (AIMS ), the Great Barrier Reef has lost half of its coral cover in the last 27 years. The research team attributes this...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
