Sea turtles struggle to find food with rising temperatures MIAMI, Aug. 22, 2014 /PRNewswire-USNewswire/ -- An unprecedented marine heat wave that swept the Southeast Indian Ocean in 2011 has given FIU scientists a glimpse into the future of climate change. The heat wave caused the loss of more than 90 percent of the dominant seagrass in some regions of Shark Bay, Australia. Since seagrass meadows provide habitat for many ecologically important species, and provide food for large...

MIAMI, Aug. 13, 2014 /PRNewswire-USNewswire/ -- The loss of sharks could contribute to the destruction of one of the planet's most under-appreciated sources of carbon storage -- seagrasses. While sharks are often sensationalized as voracious predators, it's their actual prey that poses a risk to seagrasses, according to FIU researchers. "Seagrasses around the world are under considerable threat -- from pollution to dredging and changes in water quality," said Mike Heithaus, interim...

University of New South Wales The migration of tropical fish as a result of ocean warming poses a serious threat to the temperate areas they invade, because they overgraze on kelp forests and seagrass meadows, a new study concludes. The harmful impact of tropical fish is most evident in southern Japanese waters and the eastern Mediterranean, where there have been dramatic declines in kelps. There is also emerging evidence in Australia and the US that the spread of tropical fish...

Seed-filled Buoys Could Help Restore Marine Meadows In San Francisco Bay
2014-02-22 07:11:14

San Francisco State University A pearl net filled with seedpods, tethered by a rope anchored in the coastal mud but swaying with the tide, could be an especially effective way to restore disappearing marine meadows of eelgrass, according to a new study. The resulting crop of eelgrass grown by SF State researchers is as genetically diverse as the natural eelgrass beds from which the seeds were harvested, said Sarah Cohen, an associate professor of biology at the Romberg Tiburon Center....

Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur. If the seagrass contains sulfur, it is an indication that the seabed is stressed and that the water environment is threatened. The technique will help biologists all over the world in their effort to save the world’s seagrass meadows. Seagrass meadows, such as eelgrass or Halophila, grow along most of the world's coasts where they provide important habitats for a wide variety of life...

Sea Otters Helping In The Fight Against Poor Water Quality

redOrbit Staff & Wire Reports - Your Universe Online Scientists studying seagrass beds in one of the largest estuaries in central California are crediting its recovery on the return of sea otters to the coastal region, according to new research published in this week’s edition of the Proceedings of the National Academy of Sciences. According to Suzi Gage of BBC News, seagrass at Elkhorn Slough in Monterey County was “heading for extinction” due to an increase in pollution in...

Key Role In Marine Ecosystem Health Played By Tiny Grazers
2013-04-03 10:55:32

USGS Tiny sea creatures no bigger than a thumbtack are being credited for playing a key role in helping provide healthy habitats for many kinds of seafood, according to a new study by the Virginia Institute of Marine Science and U.S. Geological Survey. The little crustacean “grazers,” some resembling tiny shrimp, are critical in protecting seagrasses from overgrowth by algae, helping keep these aquatic havens healthy for native and economically important species. ...

Fish Have Huge Nutrient Impacts On Marine Ecosystems
2012-12-12 09:33:47

University of Georgia Fish play a far more important role as contributors of nutrients to marine ecosystems than previously thought, according to researchers at the University of Georgia and Florida International University. In a pair of papers in the journal Ecology, they show that fish contribute more nutrients to their local ecosystems than any other source-enough to cause changes in the growth rates of the organisms at the base of the food web. Jacob Allgeier, a doctoral student in...

Michael Crumbliss for RedOrbit.com This week new research was published that points to seagrasses as a solution to climate change. Seagrass can store up to twice the carbon of the world´s terrestrial forests. The paper, "Seagrass Ecosystems as a Globally Significant Carbon Stock," is the first global analysis of carbon stored in seagrasses and was published in the journal Nature Geoscience.  The research was led by James Fourqurean of Florida International University, in...

The Slender sea star (Astropecten spinulosus), is a species of starfish in the Astropectinidae family. It is found only in the Mediterranean Sea, spending much of its life on sandy, muddy or gravelly seabed in areas very rich in algae from 3.5 to 165 feet deep. Its favorite seabed meadows are Mediterranean Tapeweed (Posidonia oceanica) and Little Neptune Grass (Cymodocea nodosa). The common name Sea Star is a generic term given to other members of this genus as well. This sea star spends...

The Rusty Carpetshark (Parascyllium ferrugineum) is a species of fish in the family Parascylliidae. It is found off the southern coast of Australia, between latitudes 31° S and 41° S. They are typically found in water at depths between 15 and 500 feet. It occurs on beds of algae on reefs or seagrass, and also hides in rocky caves and ledges during the day. The Carpetshark grows to about 31.5 inches long. The mouth is in front of the eyes. It is gray-brown in color with an unclear...
