Coral Bleaching Study Explains Different Responses To Climate Change
2013-04-24 12:24:35

Brett Smith for redOrbit.com - Your Universe Online When corals become stressed, they expel their symbiotic algae companions in a process known as “bleaching.” Corals can survive the bleaching, but it leaves them highly vulnerable and often results in die-off. As a changing climate threatens to bleach the corals of the world´s oceans on a massive scale, a team of researchers from Northwestern University has found that some corals facilitate bleaching through the...

Israeli Scientists Discover Why Soft Corals Pulsate
2013-04-23 14:17:24

The Hebrew University of Jerusalem [ Watch the Video Pulsating Coral In The Gulf Of Eilat ] Scientists from the Hebrew University of Jerusalem and the Technion-Israel Institute of Technology have discovered why Heteroxenia corals pulsate. Their work, which resolves an old scientific mystery, appears in the current issue of PNAS (Proceedings of the National Academy of Sciences in the US). One of the most fascinating and spectacular sights in the coral reef of Eilat is the perpetual...

Cape Coral, Florida injury and accident lawyer website just launched by the Berman Law Group. Cape Coral, Florida (PRWEB) April 14, 2013 The Berman Law Firm is proud to announce a new Cape Coral, Florida injury lawyer website helping all of the citizens of Cape Coral. Cape Coral, Florida, is located on the west coast of Florida, and is a lively destination for many people, but with that said a lot of accidents occur there each year due to the high concentration of people living in the area....

Coral Reefs Also Under Threat From Air Pollution
2013-04-08 04:30:56

redOrbit Staff & Wire Reports - Your Universe Online Fine particles in the air resulting from burning coal or volcanic eruptions can negatively affect coral growth, a team of climate scientists and coral ecologists from the UK, Australia and Panama has discovered. The study, which appears in this week´s edition of the journal Nature Geoscience, found that coral reefs respond to changes in the concentration of atmospheric pollution. Those particulates can shade the corals from...

Sustainable Fishing Practices Reap Local Rewards
2013-03-28 16:28:27

Cell Press Communities that act locally to limit their fish catches will reap the rewards of their action, as will their neighbors. That's the conclusion of a study reported on March 28 in the Cell Press journal Current Biology of the highly sought-after fish known as squaretail coral grouper living in five community-owned reef systems in Papua New Guinea. "We found that many larvae that were produced by the managed adults return to that same fish population, which means that the same...

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...

Increase In Coral Reef Bleaching Attributed To Climate Change
2013-02-25 19:26:09

Michael Harper for redOrbit.com — Your Universe Online Rising temperatures associated with climate change have already been shown to have an effect on a wide range of ecosystems and the creatures that reside within. Recent studies have now added coral reefs to the list of ecosystems that may be damaged as a result of climate change. Judging from new maps and models, the rising sea temperatures, which accompany climate change, could result in more frequent coral bleaching events,...

Manmade Activities Behind Caribbean Coral Die-Off
2013-02-15 10:42:20

April Flowers for redOrbit.com - Your Universe Online A new study, led by the University of Georgia, solves the mystery of the dying Caribbean coral. Plunk down a wastewater treatment plant anywhere along a Caribbean coast and watch the coral reefs nearby start dying, by a means unknown to science. "You'd have all the makings of a great mystery novel," says ecologist James Porter of the University of Georgia. Unlike a novel, however, this story is true. "Between 1996 and 2012,...

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
2013-02-17 07:58:30

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...
