These shells don't clam up: Innovative technique to record human impact on coastal waters
With their sedentary lifestyles and filter-feeding habits, clams have been silent witnesses to the changes that humans have inflicted upon their waters. view more (2008-12-03)
Annual Tahoe Report Says Asian Clam Invasion Is Growing Fast
Released today, UC Davis' annual Lake Tahoe health report describes a spreading Asian clam population that could put sharp shells and rotting algae on the spectacular mountain lake's popular beaches, possibly aid an invasion of quagga and zebra mussels, and even affect lake clarity and ecology. view more (2009-08-19)
Paleontologists learn how not to become a fossil
The best way to avoid becoming a fossil is to be small and live in deep, tropical waters. So say four paleontologists who have published a detailed, global study of clam preservation. view more (2006-04-13)
Deep in the ocean, a clam that acts like a plant
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. view more (2007-02-21)
Are walruses right-handed?
Walruses are 'right-flippered', according to research published this week in BMC Ecology. The first study of walrus feeding behaviour in the wild showed that the animals preferentially use their right flipper to remove sediment from buried food. This is the first time that any aquatic animal has been shown to prefer using one flipper to the other... view more... (2003-10-17)
Ancient whale fall from California's Año Nuevo Island one of youngest, most complete known
A fossilized whale skeleton excavated 20 years ago amid the stench and noise of a seabird and elephant seal rookery on California's Año Nuevo Island turns out to be the youngest example on the Pacific coast of a fossil whale fall and the first in California, according to University of California, Berkeley, paleontologists.

Brown Scientist Finds Coastal Dead Zones May Benefit Some Species
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. view more (2008-10-15)
MBL Scientists Find Evidence of RNA in Organelle Essential to Cell Division
Despite more than a century of study, scientists know relatively little about the inner workings of centrosomes—organelles essential to cell division in humans and animals. view more (2006-06-07)
500 million years of errors: Brachiopod shells record shadow of arms race in ancient oceans
A study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators. However, the rare predation traces left on brachiopod shells by unknown assailants coupled with a subtle increase in their frequency through time may be the shadows on the wall that show killers were in the... view more...

Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.
Clams, mussels and oysters are important vehicles for the transmission of enteric diseases when consumed raw or undercooked. Vibrio species, including human pathogens, are particularly abundant in bivalve tissues, where they can persist even after cleaning procedures, thus representing a potential risk for human health. Although different... view more... (2005-05-25)
Overfishing great sharks wiped out North Carolina bay scallop fishery
Fewer big sharks in the oceans led to the destruction of North Carolina's bay scallop fishery and inhibits the recovery of depressed scallop, oyster and clam populations along the U.S. Atlantic Coast, according to an article in the March 30 issue of the journal Science. view more (2007-03-30)
Rare albino ratfish has eerie, silvery sheen
A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound. view more (2007-09-25)
Excellent Underwater Vision Examined by Scientists from Lund
We humans are poorly adapted for underwater vision. However, the Moken peoples of south-east Asia manage to collect shells, clams and sea cucumbers using no visual aids when diving to a depth of 3 or 4 metres. Scientists from Lund University in Sweden have now measured the visual acuity of these children and have found that their ability to see... view more... (2003-05-15)
Analysis finds strong match between molecular, fossil data in evolutionary studies
During a seminar at another institution several years ago, University of Chicago paleontologist David Jablonski fielded a hostile question: Why bother classifying organisms according to their physical appearance, let alone analyze their evolutionary dynamics, when molecular techniques had already invalidated that approach? view more (2009-04-29)
New map outlines risk of zebra mussel invasion
The spread of two invasive alien freshwater mussel species - the zebra mussel and the quagga mussel - appears to be controlled in part by calcium levels in streams and lakes and a new risk assessment based on water chemistry suggests the Great Plains and American Southwest could be next in line for invasion. view more (2007-12-04)
Sea Grant warns of dumping seafood
In its latest outreach campaign, MIT Sea Grant has developed an educational pamphlet to encourage people not to release or dump live and fresh seafood and seafood waste into the wild. view more (2006-06-22)
Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply
Fewer big sharks in the oceans mean that bay scallops and other shellfish may be harder to find at the market, according to an article in the March 30 issue of the journal Science, tying two unlikely links in the food web to the same fate. view more (2007-03-30)
UCSB researcher leads worldwide study on marine fossil diversity
It took a decade of painstaking study, the cooperation of hundreds of researchers, and a database of more than 200,000 fossil records, but John Alroy thinks he's disproved much of the conventional wisdom about the diversity of marine fossils and extinction rates. view more (2008-07-11)
Scientists: New phylum sheds light on ancestor of animals, humans
Genetic analysis of an obscure, worm-like creature retrieved from the depths of the North Atlantic has led to the discovery of a new phylum, a rare event in an era when most organisms have already been grouped into major evolutionary categories. view more (2006-11-03)
Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters
Seventeen years after the Exxon Valdez ran aground in Alaska's Prince William Sound, compelling new evidence suggests that remnants of the worst oil spill in U.S. history extend farther into tidal waters than previously thought, increasing the probability that the oil is causing unanticipated long-term harm to wildlife. view more (2006-05-16)
