Ingredient in Prozac increases risk of extinction for freshwater mussels
You'd think in a river filled with anti-depressants, freshwater mussels would be, well, happy as clams. Far from it. In fact, a new laboratory study suggests that exposure to Prozac can disrupt the reproductive cycle of these mollusks, potentially increasing their risk of extinction. (2006-09-11)

Study reveals details of mussels' tenacious bonds
When it comes to sticking power, marine mussels are hard to beat. They can adhere to virtually all inorganic and organic surfaces, sustaining their tenacious bonds in saltwater, including turbulent tidal environments. Little is known, however, about exactly how the bivalves achieve this amazing feat. Now Northwestern University researchers shed new light on the adhesive strategies of mussels, information that could be used to develop adherents or repellants for use in medical implants.

Strong impact of wintering waterbirds on zebra mussel populations at Lake Constance, Germany
The numbers of overwintering waterbirds at Lake Constance, have increased fourfold since the early 1960s, as shown by a study published in Freshwater Biology. The main avian population changes concerned the mussel-eating tufted duck, pochard and coot. Each bird consumes about 1.4 kg of mussels (fresh mass) per day. It is apparent that wintering waterbirds exert a strong top-down effect on the littoral community, but the mussel stocks recover every summer during the absence of their main predators. (2005-07-20)

Shark skin saves naval industry money
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┬┤. Ralph Liedert from the University of Applied Sciences, Bremen, Germany, is presenting his work on the application of artificial shark skin in a new anti-fouling strategy at the Society for Experimental Biology Annual Main Meeting in Barcelona [session A7.66].

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. (2005-05-25)

Innovative coating could give medical implants a longer life
By mimicking an adhesive protein secreted by mussels and a polymer that repels cells and proteins, Northwestern University researchers have designed a two-sided antifouling coating that could breathe life into medical implants. Currently the longevity of certain implants suffers because bacteria, cells and proteins in the body accumulate on the devices. The new coating, which sticks to a surface and prevents cell and protein buildup, has been shown to work for a long period of time. (2005-05-13)

Diversity, endemism, and age distributions in macroevolutionary sources and sinks
Regions with high diversity or many unique species are often assumed to be hotbeds of species origination, but a new theory demonstrates that such places could instead result from the immigration of species. This theory, outlined in an article to appear in the June 2005 issue of The American Naturalist, also shows how combining the ages of species, determined from the fossil record, with information on where those species currently live can give insight into the past processes that have shaped diversity. (2005-04-15)

Diversity hot spots at cold seeps?
In the most recent issue of Ecology Letters, researchers report that diversity is greater in seep mussel beds compared to vent mussel beds. Lower diversity at vents may be a consequence of a challenging physiological barrier to invasion at vents than at seeps. Moreover, diversity at vents is lowest where spacing between vents is extensive, suggesting that risks of extinction due to limited dispersal may be important in governing biodiversity in the deep sea. (2003-05-22)

Finicky snails provide new clues to the evolution of coastal ecosystems
Mussels have long been a favorite of seafood lovers. But it turns out that inch-long marine snails can be pickier than people.
