The rapid growth of the oyster aquaculture industry in Rhode Island has raised questions about how many oyster farms Narragansett Bay and the state's salt ponds can support. But a study by a University of Rhode Island graduate student has found that these ecosystems can withstand continued high rates of aquaculture growth without causing ecological harm. Carrie Byron, a doctoral student in the URI Department of Fisheries, Animal and Veterinary Science, examined the ecological carrying...

Acidity is increasing in some regions of the Chesapeake Bay even faster than is occurring in the open ocean, where it is now recognized that increased levels of atmospheric carbon dioxide dissolve in the seawater thereby making it more acidic. These more acidic conditions in key parts of Chesapeake Bay reduce rates of juvenile oyster shell formation, according to new research published in the journal Estuaries and Coasts. The study, conducted at the University of Maryland Center for...

A new study has reinforced the idea that the first British colonists in America had to endure an unusually severe drought. Jamestown in Virginia was the first successful English settlement in North America. Chemical analysis of shells thrown away from 1611-1612 show that the James River was much saltier then than it is today. This was due to decreased flow from surrounding freshwater rivers. Rainfall must have been much lower when these oysters were growing in order for this to have been...

Shells from oysters, clams, and periwinkles hold clues about the ways and rates at which harmful compounds from the spill are being incorporated into the Gulf's marine food web New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? Scientists currently know very little about how long it takes for the...

Acidifying oceans dramatically stunt growth of already threatened shellfish As we prepare to celebrate Earth Day on April 22, we can add another species, one of widespread ecological and economic importance, to the list of the beleaguered. From East Coast to West and around the world, global warming and its effects have descended upon shellfish reefs, particularly those formed by the Olympia oyster. More than one-third of the world's human-caused carbon dioxide emissions have entered the...

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...

In physical, as in financial growth, it's not what you make but what you keep that counts, USC marine biologists believe. Their study of genes associated with growth in oysters suggests that slow-growing animals waste energy in two ways: by making too much of some protein building blocks and then by having to dispose of the excess. Donal Manahan, director of the USC Wrigley Institute for Environmental Studies and the study's senior author, calls the inefficient process "metabolic taxation."...

Iron atoms convey mussel fibers with a robust but stretchy covering We may like to eat mussels steamed in white wine, but we also like to find mussels at the beach. Mostly they are burrowed into the ground or tethered to rocks. But if you look closer you will find a mollusc which has adapted to life and nutrition in a special and fascinating way. Mussels thrive in rocky seashore habitats, in spite of the enormous physical demands present there. This is in no small part due to the evolution of...
