With their sedentary lifestyles and filter-feeding habits, clams have been silent witnesses to the changes that humans have inflicted upon their waters. These clams are silent no more, as Dr. Ruth H. Carmichael of the Dauphin Island Sea Lab and her colleagues have reported in their recent paper in the prestigious journal Aquatic Biology. Using stable isotope techniques, Carmichael demonstrated it is possible to identify and trace wastewater inputs to estuaries and coastal food webs by...

A U.S. ecologist says he's found a commercially valuable species of clam thriving in oxygen-depleted waters of a so-called "dead zone" off the East Coast. Andrew Altieri, a post-doctoral researcher at Brown University, discovered the population of quahog clams increased in hypoxic zones, defined as areas in which dissolved oxygen in the water has been depleted. He said he determined whether quahog clams have a natural capacity to survive in oxygen-starved waters, but their predators...

Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted waters. Andrew Altieri, a post-doctoral researcher in the Department of Ecology and Evolutionary Biology at Brown University, studied dead zones in Narragansett Bay, one of the largest estuaries on...

Older sources may give it the systematic name Venus mercenaria. It is one of many unrelated bivalves referred to as clams. Hard clams are quite common throughout New England, north into Canada, and all down the Eastern seaboard of the United States to Florida, but are particularly abundant between Cape Cod and...
