Green Plants Share Bacterial Toxin
A toxin that can make bacterial infections turn deadly is also found in higher plants, researchers at UC Davis, the Marine Biology Laboratory at Woods Hole, Mass. view more (2006-11-07)
Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and marine chemists. view more (2007-09-10)
Red Tide causes sea turtle die-off in El Salvador
A "Red Tide" event that occurred off the coast of El Salvador late last year directly caused the deaths of some 200 sea turtles. view more (2006-03-24)
North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels. view more (2005-10-11)
Ocean 'dead zones' trigger sex changes in fish, posing extinction threat
Oxygen depletion in the world's oceans, primarily caused by agricultural run-off and pollution, could spark the development of far more male fish than female, thereby threatening some species with extinction. view more (2006-03-30)
Researchers link ocean organisms with increased cloud cover and potential climate change
Atmospheric scientists have reported a new and potentially important mechanism by which chemical emissions from ocean phytoplankton may influence the formation of clouds that reflect sunlight away from our planet. view more (2006-11-08)
Algae provide new clues to cancer
A microscopic green alga helped scientists at the Salk Institute for Biological Studies identify a novel function for the retinoblastoma protein (RB), which is known for its role as a tumor suppressor in mammalian cells. view more (2006-10-13)
New research in Chesapeake Bay, Pamlico Sound shows hurricanes, runoff tax water quality management efforts
A scientific study that involved analyzing phytoplankton in both North Carolina's Neuse River Estuary/Pamlico Sound and Maryland and Virginia's Chesapeake Bay offers a new lesson in light of recent increased hurricane activity along the East Coast, researchers say. view more (2005-12-23)
Accelerating loss of ocean species threatens human well-being
An international group of ecologists and economists has shown that the loss of biodiversity is profoundly reducing the ocean's ability to produce seafood, resist diseases, filter pollutants and rebound from stresses such as overfishing and climate change. view more (2006-11-07)
Europe's largest climate change experiment launched
Scientists at the University of Liverpool have launched a large scale experiment to monitor the impact of climate change on freshwater systems. view more (2006-01-18)
Discovery of method to combat toxic algal blooms and description of a new group of organisms
In the fall of 1997 a then unknown species of plankton, Parvilucifera infectans, was discovered in the Gullmar Fjord, on the west coast of Sweden. The organism is a parasite that infects and kills several species of toxic algae. Some of these toxic algae can generate extremely potent blooms at great cost to fisheries and the tourism industry... view more... (2002-04-18)
Fishing kills Fijian coral reefs
Outbreaks of a coral-eating starfish have occurred in Fiji resulting from overexploitation of the predatory fishes that normally limit its numbers. The impacts of the starfish are dramatic, with previously pristine coral reefs being turned into dull algal mats. Worryingly, Dulvy, Freckleton and Polunin - the authors of a study in the May issue of... view more... (2004-05-04)
Arctic Coring Expedition Continues to Yield New Clues About Climate Change
For the second time in as many months, the IODP Arctic Coring Expedition (ACEX) is making news with new analysis of ocean-floor sediments. view more (2006-08-10)
Advance in cholera bacteria points to new treatment and vaccine
Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans. view more (2005-12-08)
World's largest flower evolved from family of much tinier blooms
The plant with the world's largest flower - typically a full meter across, with a bud the size of a basketball - evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science. view more (2007-01-12)
Study reveals classic symbiotic relationship between ants, bacteria
Ants that tend and harvest gardens of fungus have a secret weapon against the parasites that invade their crops: antibiotic-producing bacteria that the insects harbor on their bodies. view more (2006-01-06)
Sunscreens from the sea
Tiny floating plants protect themselves against the damaging effects of the sun's ultra violet rays using compounds that may prove very useful to the skincare industry. Scientists at the Plymouth Marine Laboratory are now working with Boots Company plc to develop the potential of these natural sunscreens for human skincare. "Because... view more... (2001-07-18)
Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the July issue of Ecology Letters, Duffy, Canuel, and... view more... (2003-07-02)
Fish species plays surprise role in aiding coral reef recovery
In a study that marks progress in understanding the basis of coral reef recovery, researchers have revealed the critical importance of a rare batfish, Platax pinnatus, in promoting the return to health of a disturbed coral reef overgrown with algae. view more (2006-12-19)
Changes in reef latitude
Since the 1980s, researchers have hypothesized that nutrient levels rather than temperature are the main factor controlling the latitudinal bounds of coral reefs, but the issue remains controversial. view more (2006-02-22)
