Pearly mussels: One of North America's natural jewels is disappearing

If you have spent time boating or fishing in freshwater, there is a good chance you have encountered a pearly mussel. Elliptical in shape, with iridescent inner shells, humans have appreciated the animals since prehistoric times. Coveted for their pearls and mother-of-pearl shells; their meat has been a resource for both humans and wildlife. In a BioScience paper published this week, a team of scientists report that something troubling has been happening in our nation's freshwaters-- once-abundant pearly mussels are disappearing from the landscape.

Written by a team of seven mussel experts, the paper concludes that, "Many pearly mussel populations have a negative growth rate and are likely to disappear unless environmental conditions change." To protect the animals, the authors urge simultaneous research and conservation actions, among them increased research on mussel biology and the protection of mussel habitat.

Though humans have been interacting with mussels for millennia, there are large gaps in our understanding of their life history and the role they play in freshwater ecosystems. Lead author Dr. David L. Strayer, a freshwater ecologist at the Institute of Ecosystem Studies, remarks, "Pearly mussels are imperiled by human activities, such as pollution, dam construction, and channelization. Dozens of species are already extinct and well over a hundred species are in danger of disappearing. For many mussel species, without intervention, future populations will be limited to specimens in museum drawers."

Unique and highly specialized animals, mussels begin life as larvae before spending their adulthood as sedentary bivalves. Larvae, which are microscopic in size, parasitize a fish host before settling to the bottom of a freshwater ecosystem. Very specific in their choice of host, some mussels use elaborate lures to attract the correct fish species. In adulthood, pearly mussels act as filter feeders, eating plankton and other small parti
