Picky Eaters Keep Endangered Coral Reefs Clean
2013-02-14 06:19:23

[ Watch the Video: Picky Eater Fish Endanger Coral Reefs ] Peter Suciu for redOrbit.com — Your Universe Online Few pet owners would expect their dog or cat to clean up the house, and anyone who has ever camped in places such as Yellowstone Park knows that bears can visit and will leave a campsite in worse shape than they found it. Fish on the other hand could actually be doing some good in cleaning up coral reefs. A recent study conducted in the Fiji Islands found that four...

Investigating Coral Speciation And Adaptation
2013-02-07 19:34:01

Brett Smith for redOrbit.com — Your Universe Online When Darwin first formed his theory of evolution, he noted how physical isolation due to geographic barriers could result in the development of specialized adaptations. These novel adaptations were then selected and passed on to future generations. Eventually a new species would evolve. While many researchers are focused on how physical barriers and isolation can lead to new species on land, a pair of LSU biologists are more...

Researchers from the University of Bonn found out that tiny foraminifera in the oceans can save islands The climate is getting warmer, and sea levels are rising — a threat to island nations. As a group of researchers lead by colleagues from the University of Bonn found out, at the same time, tiny single-cell organisms are spreading rapidly through the world's oceans, where they might be able to mitigate the consequences of climate change. Foraminifera of the variety Amphistegina are...

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...

Coral Fossils Say 20th Century El Nino Was Intense But Not Unusual
2013-01-04 12:28:23

Watch the video “Examining Fossil Corals” April Flowers for redOrbit.com - Your Universe Online Scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation (ENSO), a Pacific Ocean climate cycle that affects weather patterns worldwide, by examining a set of 7,000-year-old fossilized corals. The teams says that their study will help assess the accuracy of climate model predictions for twenty-first-century climate change in...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered corals at Australia´s Great Barrier Reef at depths that were previously believed to be uninhabitable. A team of researchers with the University of Queensland's Seaview Survey has been working on a multi-year project to map out the Great Barrier Reef, and they recently announced that they have found corals in waters nearly as dark as night. The newly discovered corals sit at 410 feet below the surface at...

China´s coral reefs have suffered a devastating 80 per cent decline in recent decades, driven mainly by the country´s unrestrained economic development, according to a new international scientific study. The first comprehensive survey of the state of corals along mainland China and in the South China Sea reports a grim picture of decline, degradation and destruction resulting from coastal development, pollution and overfishing. A new study by Professor Terry Hughes and Matthew...

Damaged Corals Have A Hard Time Reproducing
2012-12-18 06:32:57

April Flowers for redOrbit.com - Your Universe Online New research from the University at Buffalo reveals that coral colonies in the Bahamas that have suffered tissue damage were still producing low numbers of eggs four years after the initial injuries. The study, recently published in the Journal of Experimental Marine Biology and Ecology, showed that tiny sperm-producing factories called spermaries were in short supply as well. UB geology professor Howard Lasker, PhD led the study on...

Corals Shrinking Around Equator Thanks To Global Warming
2012-12-11 14:34:21

Brett Smith for redOrbit.com - Your Universe Online As the clamoring for a more comprehensive strategy to battle climate change continues, scientists are producing more and more research that suggests incremental changes in global temperature can have a massive effect on ecosystems. A new study from a team of Australian and German researchers showed that when sea surface temperatures increased by about 0.7 degrees Celsius during the last interglacial warm period, the Earth´s...

Government Agency Proposes Dozens Of Coral Species For Endangered Species Act
2012-12-03 16:06:58

Lee Rannals for redOrbit.com — Your Universe Online A new Endangered Species Act listings proposed by the National Oceanic and Atmospheric Association (NOAA) would cover 66 coral species found in the Pacific and the Caribbean. NOAA said that in 2009, it received a petition to list 83 species of reef-building corals under the ESA from the Center for Biological Diversity. The organization found that the Center presented substantial information indicating a listing under the ESA...

Crown Of Thorns Starfish, Acanthaster planci
2013-11-11 10:54:41

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Foxface Rabbitfish, Siganus vulpinus

Image Credit: Dr. Wayne Meadows (NOAA)/Wikipedia The foxface rabbitfish is found in coral rich lagoons, and reefs in the coastal water of the Western Pacific. Around the western Philippines, Indonesia, New Guinea, the Great Barrier Reef, New Caledonia, Caroline Islands, and the Marshall Islands. It has also been sighted around Vanuatu, Nauru, Kiribati, and recently Tonga. Adults usually swim in pairs, but the juveniles have been known to form schools. The adult foxface rabbitfish is...

Barrier Reef Anemonefish, Amphiprion akindynos

The Barrier Reef Anemonefish (Amphiprion akindynos) is native to the marine lagoons and reefs in the Western Pacific Ocean.  It lives at a depth of around eighty-two feet in temperatures fluctuating between fifty degrees Fahrenheit to 89.6 degrees Fahrenheit. Its range includes northern New South Wales, the Loyalty Islands, Tonga, New Caledonia, Coral Sea, and the Great Barrier Reef. They are typically seen near or within the tentacles of their host anemones. They will inhabit anemones like...

Knotted Fan Coral, (Melithaea ochracea), is a species of colonial soft coral that is found in tree-like fans on shallow reefs in the South China Sea between Taiwan and Indonesia, including Singapore and Malaysia. In Taiwan, it is the most widespread coral in its family Gorgonacea. It is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 1.6 to 16 inches per second. This species usually grow to about 8 inches in length, with...
