A drastic decrease in the population of freshwater mussels could have dire effects on fish and humans alike. Zoologist Caryn Vaughn from Oklahoma´s Aquatic Research Facility in Norman has been researching these freshwater mussels for over 20 years. She says she´s concerned about the drastic decrease in mussel population that´s occurred in that time. Vaughn told the National Science Foundation “This one river that we´ve been working in for over 20 years, we...

Researchers from the Texas A&M Institute of Renewable Natural Resources have discovered fresh remains of a freshwater mussel species thought to be extinct in Texas, according to a research associate with the institute. Dr. Charles Randklev said his research team found a single individual of false spike "Quadrula mitchelli" with tissue still in the shell "” which indicates that the individual was recently alive "” in the San Saba River in Central Texas. Mussel thought to be...

Scientists working with the Partnership for the Delaware Estuary and The Academy of Natural Sciences have made an important discovery in the Delaware River between Chester, Pennsylvania, and Trenton, New Jersey: beds of freshwater mussels. This includes several uncommon species, two of which were previously believed to no longer exist in both Pennsylvania and New Jersey. "Freshwater mussels are very sensitive to a variety of problems, including pollution, dams, water flows, loss of forests,...

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. And in a novel development, the conservation scientists from Queen's will be able to keep tabs on the precious mussels after attaching tags to the outside of...

Biodiversity in freshwater systems is impacted as much or more by environmental change than tropical rain forests, according to University of Oklahoma Professor Caryn Vaughn, who serves as director of the Oklahoma Biological Survey. "When we think about species becoming extinct, we don't necessarily think of the common species in freshwater systems, many of which are declining," says Vaughn. "We need to be concerned about these declines, because these common species provide many goods and...

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. Research conducted by Suzanne Peyer, a doctoral candidate in the University of Wisconsin-Madison Department of Zoology, shows that physiological differences between the two species might determine which mollusk...

By Ray Grass For the Deseret News Utah biologists' worst fears may come true. Early tests show quagga and zebra mussels may have found their way into three Utah reservoirs. Early tests, however, show that three of Utah's most popular waters -- Bear Lake, Flaming Gorge and Lake Powell -- have not been contaminated. Larry Dalton, aquatic invasive species coordinator for the Utah Division of Wildlife Resources, said samples were taken from 42 waters in Utah. He said Pelican Lake, Red Fleet...

LITTLE ROCK - The U.S. Fish and Wildlife Service plans to declare extinct the turgid-blossom pearly mussel, a species once found in the Black and White rivers in Arkansas and other parts of the South. That particular mussel species has been on the endangered species list since 1976. Wildlife officials say a five-year review found no sign of the mussel. "We really have no idea what caused it (to become extinct)," Jim Widlak, a fish and wildlife biologist, told the Arkansas Democrat-...

By Erin Fuchs, Chattanooga Times/Free Press, Tenn. Oct. 28--DALTON, Ga. -- During a summer survey of freshwater mussels, conservationist Nate Thomas saw the mollusks struggling to find enough water in the Conasauga River to thrive. "You could literally see the trails the shells made (in the mud) as they moved up and down the bank, looking for water," said Mr. Thomas, who runs The Nature Conservancy's North Georgia operation. "Some of them made it. Some of them didn't." The Conasauga...
