Mussels evolve quickly to defend against invasive crabs
Scientists at the University of New Hampshire (UNH) have found that invasive crab species may precipitate evolutionary change in blue mussels in as little as 15 years. view more (2006-08-11)
Shark skin saves naval industry money
Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. view more (2005-07-18)
Prehistoric Decline of Freshwater Mussels Tied to Rise in Maize Cultivation
USDA Forest Service (FS) research suggests that a decline in the abundance of freshwater mussels about 1000 years ago may have been caused by the large-scale cultivation of maize by Native Americans. view more (2005-06-08)
Virginia Tech fisheries department releases cultivated mussels at Nature Conservancy site
Virginia Tech's Freshwater Mussel Conservation Center and Virginia's Aquatic Wildlife Conservation Center in Marion, Va., released several thousand mussels that have been propagated into the Clinch River. view more (2005-06-21)
Reservoirs may accelerate the spread of invasive aquatic species, researchers say
Just as disturbance makes a landscape susceptible to invasion by alien plant species, the construction of reservoirs around the globe could be contributing to the accelerating spread of exotic aquatic species. view more (2005-05-31)
Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide. view more (2008-11-25)
Sea Grant warns of dumping seafood
In its latest outreach campaign, MIT Sea Grant has developed an educational pamphlet to encourage people not to release or dump live and fresh seafood and seafood waste into the wild. view more (2006-06-22)
Prozac exposure found to disrupt mussel reproduction
Researchers from the National Institute of Standards and Technology (NIST) and North Carolina State University (NCSW) have demonstrated that a commonly prescribed antidepressant can interfere with the reproductive cycle of freshwater mussels-at least in a controlled setting. view more (2006-09-18)
Life in the extreme
Cold seeps are deep-sea environments, usually a few square meters in size, where fluid is released through slow diffusion from the sea floor. Mud volcanoes which are active areas of fluid seepage, are other extreme environments discovered in the 1990s. These harsh conditions give rise to some of the most extreme and scientifically challenging... view more... (2006-11-09)
Frozen shellfish to combat pollution
Millions of tiny oysters and mussels are being frozen and stored for the future to help combat marine pollution around Britain’s coast. Until now, testing for pollution using these living indicators could only be done in the summer when the shellfish were reproducing. This new method combines cryogenic technology with a secret recipe of... view more... (2001-11-28)
Living laboratory found on shoreline statues
A team from the University of Liverpool's School of Biological Sciences have found that the 100 life-size statues which make up Antony Gormley's 'Another Place' art installation on Crosby Beach have become a haven for a settlement of a particular breed of barnacle-Elminius modestus. view more (2006-10-23)
Cockles and mussels reveal all
Cockles and mussels harvested on the shores of the Irish Sea may have provided a staple diet for Molly Malone and her fellow Dubliners, but for scientists at the University of Wales, Aberystwyth they are, along with longer living species such as the clam Arctica islandica*, a detailed record of pollution extending back over two centuries. The... view more... (2004-04-01)
Higher stress leads to longer life
Eating less may make you healthier: even more reason to start that diet tomorrow. Scientists at the Plymouth Marine Laboratory have found that eating less helps marine animals cope with pollution and other stressful situations, and may even let them live longer. Professor Michael Moore found that triggering a cellular process known as autophagy in... view more... (2004-03-26)
Tropical crab invades Georgia oyster reefs -- but the long-term impact can't be predicted
A dime-sized tropical crab that has invaded coastal waters in the Southeast United States is having both positive and negative effects on oyster reefs, leaving researchers unable to predict what the creature's long-term impact will be. view more (2007-09-05)
Biological invasions increasing due to freshwater impoundments, says CU-Boulder study
The growing number of dams and other impoundments is increasing the number of invasive species and the speed at which they spread, putting natural lakes at risk, says a study led by the University of Colorado at Boulder. view more (2008-09-03)
Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.
Clams, mussels and oysters are important vehicles for the transmission of enteric diseases when consumed raw or undercooked. Vibrio species, including human pathogens, are particularly abundant in bivalve tissues, where they can persist even after cleaning procedures, thus representing a potential risk for human health. Although different... view more... (2005-05-25)
New map outlines risk of zebra mussel invasion
The spread of two invasive alien freshwater mussel species - the zebra mussel and the quagga mussel - appears to be controlled in part by calcium levels in streams and lakes and a new risk assessment based on water chemistry suggests the Great Plains and American Southwest could be next in line for invasion. view more (2007-12-04)
Alternative states in the ocean
Ecologists expect natural communities to vary. Occasionally, however, such variation can be severely abrupt and lead to formation of alternative and potentially persistent states. In the July issue of Ecology Letters, Paine and Trimble describe a dramatic assemblage shift on a rocky intertidal shore in Washington State (USA). The change was... view more... (2004-05-13)
A receipe for success
Mix chocolate with some cheddar cheese; add some zebra mussels and throw in a dose of heat and what you'll get is a fresh look at what 21st century chemical engineering all about. This was the theme of a lecture held on 8th March 2004 at the University of Birmingham's chemical engineering department. The lecture's main speaker, Dr Geoff Moggridge... view more... (2004-03-08)
Sticky mussels inspire biomedical engineer yet again
Mussels are delicious when cooked in a white wine broth, but they also have two other well-known qualities before they're put in a pot: they stick to virtually all inorganic and organic surfaces, and they stick with amazing tenacity. view more (2007-10-19)
