Microplastics Worse For Crabs And Other Marine Life Than Previously Thought
2014-07-22 03:43:32

University of Exeter The tiny plastic particles polluting our seas are not only orally ingested by marine creatures, but also enter their systems through their gills, according to a new study led by the University of Exeter. Scientists also discovered that when microplastics are drawn in through this method they take over six times longer to leave the body compared with standard digestion. Lead author Dr Andrew Watts of the University of Exeter said: "Many studies on microplastics...

Marsh Crabs Show Ecological Benefits Of Invasive Species
2013-04-04 10:17:30

Alan McStravick for redOrbit.com - Your Universe Online The marsh systems around Cape Cod have been eroding at a rapid rate in the past few decades. As redOrbit reported in January, researchers from Brown University were able to find a cause and effect relationship between human interaction with the ecosystem and the rapid increase in the native purple crab population. As their research detailed, human manipulation of the region via recreational overfishing and the creation of drainage...

Ship Noise Makes Crabs Cranky

Brett Smith for redOrbit.com - Your Universe Online Private industry rarely has a stake in conservation, but a new study shows that reducing aquatic noise pollution could provide a financial boost for the fishing industry. A new study published in the journal Biology Letters found that the sounds of ship noise ramp up crab metabolism, potentially resulting in lower yields for commercial crabbers. Citing growing evidence that shows even a single noise exposure can affect a variety...

SHOCKING! Crabs Really Do Feel Pain

Brett Smith for redOrbit.com - Your Universe Online Most cultures value the humane treatment and slaughter of their livestock, and now those same standards should be applied to their seafood, according to a new behavioral study published in the Journal of Experimental Biology. The study, from Queen's University Belfast professors Bob Elwood and Barry Magee, exposed common shore crabs to electrical shocks and found those crabs responding to the shocks in a way consistent with...

Researchers have found that a species invasion that starts at the upstream edge of its range may have a major advantage over downstream competitors, at least in environments with a strong prevailing direction of water or wind currents. Scientists from the University of Georgia, University of New Hampshire, Smithsonian Environmental Research Center and University of Vermont studied populations of European green crab, Carcinus maenas. The species was introduced to the East Coast of North...

In 1988, a mysterious invader washed upon the New Jersey shore. The Asian shore crab likely arrived in ballast from commercial ships, and it found its new home to be quite agreeable. More than two decades later, the crab, Hemigrapsus sanguineus, has expanded its range along the Atlantic coast northward to Maine and southward to North Carolina. Its numbers continue to expand, and wildlife biologists have found them in greater densities along New England's cobbled shores. Another tale of an...

A study of oyster reefs in a once-pristine California coastal estuary found them devastated by invasive Atlantic Coast crabs and snails, providing new evidence of the consequences when human activities move species beyond their natural borders. Led by marine biologist David L. Kimbro, now of The Florida State University Coastal and Marine Laboratory, the study shows that in Tomales Bay, half the population of California's native Olympia oyster has perished because its habitat has fallen...

Next time you have an unlucky encounter with a crab's pinchers, consider that the claw tips may be reinforced with bromine-rich biomaterial 1.5 times harder than acrylic glass and extremely fracture resistant, says a University of Oregon scientist.Residents on the U.S. West Coast may have had close encounters with the biomaterial -- detailed by a seven-member team in a paper published online in advance of regular publication in the Journal of Structural Biology. The translucent substance...

By Lucas van Grinsven AMSTERDAM (Reuters) - Blue-collar workers in Europe and the United States who feel threatened by Asian rivals should spare a thought for local birds, crabs and oysters, also facing competition from more efficient eastern species. Dull-colored pigeons, starlings and crows used to dominate the skies above Amsterdam, but these days citizens might spot the brilliant green plumage of a long-tailed tropical parakeet. Originally from Asia, 1,200 collar parakeets now...
