Virginia Tech's College of Natural Resources partnered with federal and state agencies in this major undertaking. (2005-06-20)

Lake Michigan fish populations threatened by decline of tiny creature
The quick decline of a tiny shrimp-like species, known scientifically as Diporeia, is related to the aggressive population growth of non-native quagga mussels in the Great Lakes, say NOAA scientists. As invasive mussel numbers increase, food sources for Diporeia and many aquatic species have steadily and unilaterally declined. (2009-02-19)

Plastic pollution causes mussels to lose grip
A new study shows that microplastics are affecting the ability of mussels to attach themselves to their surroundings -- potentially having a devastating impact on ocean ecosystems as well as a worldwide industry worth between 3-4 billion US dollars per year. (2019-01-29)

A fishy change in diet
New McGill research suggests that a common freshwater fish, the yellow perch, is moving away from its traditional diet to one that is less nutritious and potentially poisonous. The consequences may be deadly to freshwater life and harmful to human food sources. (2004-09-23)

New methods improve quagga and zebra mussel identification
The earliest possible detection of quagga and zebra mussels has long been a goal of biologists seeking to discover their presence in water bodies. The Bureau of Reclamation's Detection Laboratory has released two reports identifying a new sampling method to improve the accuracy of quagga and zebra mussel detection while still at the microscopic larval stage. (2013-10-31)

Alternative states in the ocean
Ecologists expect natural communities to vary. However, variation can be abrupt and lead to formation of alternative and potentially persistent states. In Ecology Letters, July, Paine and Trimble describe a dramatic assemblage shift on a rocky intertidal shore in Washington State (USA). The study emphasizes the ecological importance and generality of size escapes, a mechanism also characterizing potentially permanent transformations of terrestrial grasslands to forests. (2004-05-13)

Freshwater Sponges May Pose Threat To Zebra Mussels
While studying a recent increase in freshwater sponges in Lake Erie, researchers at Ohio State University found that the sponges were smothering zebra mussels in some areas, eventually killing them. Researchers first noticed the increase in sponges in 1993 while studying an artificial reef built near Lorain, Ohio (1996-06-04)

Zebra mussel impact on microbenthic community low in Lake Erie
Ohio Sea Grant research by Robert Heath at Kent State University and Joseph Balczon of Westminster College, has found that unlike other aquatic nuisance species, zebra mussels may have little effect on microbenthic organisms in Lake Erie. (2000-09-18)

In field tests of the apparatus at a water treatment facility in a Cleveland suburb, the scientists found that zebra musselswere unable to attach to pipes in this oxygen-controlled environment (1997-06-02)

Risk of extinction cascades from freshwater mussels to a bitterling fish
Reproduction of native and invasive bitterling fishes and their hybridisation was studied in Japan. We collected mussels in which these bitterlings lay their eggs, kept them in aquaria, collected eggs/larvae ejected from mussels, and genotyped them. We found that hybrids occurred when local mussel density was low. The rapid decline of the host mussels and artificial introduction of an invasive congener interacted to cause the rapid decline of a native fish. (2021-01-04)

Study of aquatic mussels indicates they may yield new antifouling materials, surgical adhesives
A possible role in surgical adhesion for aquatic mussels is among research topics to be discussed at the 34th annual Great Lakes Regional Meeting of the American Chemical Society, June 2-4, at the Radisson Hotel Metrodome and the McNamara Alumni Center, in Minneapolis. (2002-06-04)

Invasive species not best conservation tool: Study
Harnessing an invasive fish species sounded like a promising conservation tool to help reverse the destruction wreaked by zebra mussels on endangered native mollusks in the Great Lakes -- except that it won't work, says a University of Guelph ecologist. (2016-04-06)

Lubricant-infused material is a slick trick against mussels

(2010-08-16)

Zebra mussels hang on while quagga mussels take over
The zebra mussels that have wreaked ecological havoc on the Great Lakes are harder to find these days -- not because they are dying off, but because they are being replaced by a cousin, the quagga mussel. But zebra mussels still dominate in fast-moving streams and rivers. (2009-06-12)

Acid attack -- can mussels hang on for much longer?
Scientists from the University of Washington have found evidence that ocean acidification caused by carbon emissions can prevent mussels attaching themselves to rocks and other substrates, making them easy targets for predators and threatening the mussel farming industry. (2016-07-05)

Radio waves stop marine pests dead in their tracks
A new method for killing zebra mussels, which cause millions of dollars in damage to boats and power plants, will be described during the national meeting of the American Chemical Society, the world's largest scientific society, in Chicago, August 26-30. The technique uses low energy radio waves that cause the mussels to lose essential minerals, such as the calcium they need to maintain their shells. (2001-08-28)

To build up mussels, you need to know your fish
Times are tough for 31 of Michigan's 45 varieties of freshwater mussels. Sporting evocative names like wavy-rayed lampmussel and round pigtoe, these residents of the state's rivers are imperiled by habitat disruption and pollution and are also threatened by climate change. Michigan State University scientists' recommendation to figure out the best places to focus conservation efforts: Worry about fish. (2018-02-27)

Small mussels in the Baltic are getting even smaller
Blue mussels in the Baltic Sea are getting smaller with time but bigger in numbers, according to a new study from Stockholm University. Analyzing data from the last 24 years, the main reason for this appears to be changes in food quality. The type of phytoplankton that is available for blue mussels to eat can in turn be linked to our changing climate. (2020-10-27)

Lakes with zebra mussels have higher levels of toxins, MSU research finds
Inland lakes in Michigan that have been invaded by zebra mussels, an exotic species that has plagued bodies of water in several states since the 1980s, have higher levels of algae that produce a toxin that can be harmful to humans and animals, according to a Michigan State University researcher. (2004-03-10)

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)

Queen's scientists boost endangered freshwater mussels population
The endangered freshwater mussel species has been given a welcome boost by scientists from Queen's University Belfast following a 12 year cultivation project. Over 300 of the mussels, which are threatened in many parts of Europe and North America, have been released back into the wild at a range of secret locations in Northern Ireland. (2010-03-23)

Marine biodiversity loss due to warming and predation: UBC researcher
The biodiversity loss caused by climate change will result from a combination of rising temperatures and predation -- and may be more severe than currently predicted, according to a study by University of British Columbia zoologist Christopher Harley. (2011-11-28)

University of Oklahoma ecology and evolutionary biology graduate student receives EPA's STAR Fellowship award
Freshwater mussels are North America's most imperiled faunal group (approximately 50 percent of mussel species are on the endangered species list), yet provide essential ecosystem services (e.g., water filtration, nutrient cycling). Ecosystem services are resources and services provided by natural ecosystems that are essential for human well-being. Atkinson is researching their environment. (2011-09-28)

Queen's University Belfast is working on a three-year study to conserve and restore endangered horse mussel reefs in Strangford Lough. (2009-01-22)

Understanding mussels' stickiness could lead to better surgical and underwater glues
Mussels might be a welcome addition to a hearty seafood stew, but their notorious ability to attach themselves to ships' hulls, as well as to piers and moorings, makes them an unwelcome sight and smell for boaters and swimmers. Now, researchers report in ACS' journal Langmuir a clearer understanding of how mussels stick to surfaces, which could lead to new classes of adhesives that will work underwater and even inside the body. (2014-06-04)

Acidifying oceans could hit California mussels, a key species
Ocean acidification, a consequence of climate change, could weaken the shells of California mussels and diminish their body mass, with serious implications for coastal ecosystems. (2011-07-14)

Rensselaer effort to 'pull mussels' at Lake George looks promising
