Research Bolsters Importance of Horseshoe Crab Spawning for Migrating Shorebirds Speculation that the welfare of a small, at-risk shorebird is directly tied to horseshoe crab populations is in part supported by new scientific research, according to a U.S. Geological Survey- led study published in Ecosphere, a journal of the Ecological Society of America. Population health of the red knot, a shorebird species whose population has plummeted over the last 15 years, has been directly tied to the...

Sensor uses frog peptides to test for drug and medical device contamination Princeton engineers have developed a sensor that may revolutionize how drugs and medical devices are tested for contamination, and in the process also help ensure the survival of two species of threatened animals. To be fair, some of the credit goes to an African frog. In the wild, the African clawed frog produces antibacterial peptides -- small chains of amino acids -- on its skin to protect it from infection....

Decline may affect at-risk shorebirdsA distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.  The new research also indicates that horseshoe crabs numbers may continue to decline in the future because of predicted climate change, said Tim King, a scientist with the U.S. Geological Survey and a lead author on the new study...

Declining numbers of a shorebird called the red knot have been linked to bait use of horseshoe crabs. Long-term surveys of red knots showed that the average weight of red knots when they leave Delaware Bay has declined significantly since their primary food source, eggs of horseshoe crabs, has been reduced. The study also revealed that red knot survivorship is related to departure weight, and that the population size of red knots has declined by more than 75 percent. "We concluded that the...

Experts are pointing to restrictions in U.S. east coast states on harvesting horseshoe crabs as the cause of the recent surge in the population of endangered migrating shore birds after years of over-fishing.Horseshoe crabs lay the eggs on the shores of the east coast every spring, and the migratory birds rely on the eggs as a source of food.Before the restrictions were put in place, commercial fishermen had harvested millions of crabs, which they used for bait while fishing for conch and...

By Jon Hurdle REED'S BEACH, New Jersey -- On a remote New Jersey beach, a team of biologists huddled behind a dune, out of sight of a flock of birds that gathered on a stretch of sand. Suddenly, there was a loud bang, and the scientists sprinted to a spot on the beach where a net, propelled by an explosive charge, trapped about 100 birds that were flapping their wings helplessly. Rushing to untangle the birds, the team released the sea gulls and then gently placed the other species -- all...

GALLOWAY TOWNSHIP, N.J. -- Environmentalists won a key battle Thursday in their efforts to protect the red knot, a small bird that migrates through the Delaware Bay. After a sometimes contentious meeting that pitted the state and environmentalists against fishermen who have plied the bay for years, the state Marine Fisheries Council - by a 7-3 vote - chose not to veto proposed rules from the Department of Environmental Protection that would implement a two-year moratorium on horseshoe crab...

TRENTON, N.J. -- Environmentalists on Tuesday will urge the governors of New Jersey and Delaware to enforce strong new protections for a migratory shorebird threatened with extinction. Eight conservation groups in the two states are rallying on behalf of the red knot, a species that migrates from South America to the Arctic to breed each spring. The birds' principal stopover is New Jersey and Delaware, where they spend weeks fattening up on horseshoe crab eggs before continuing their...

Great Knot, Calidris tenuirostris
2013-04-23 23:23:04

The Great Knot (Calidris tenuirostris) is a small sized wader, although, it is the largest of the calidrid species. Their breeding habitat is tundra in the northeast parts of Siberia. They nest on the ground, laying about four eggs in a ground scrape. They are strongly migratory, wintering on the coasts in southern Asia through to Australia. This species forms extremely large flocks during the winter. It’s a rare vagrant to western Europe. This bird has short dark legs and a...

A long-legged wading bird, The Great Knot, is the largest of the calidrid species. They breed in the tundra of North Siberia, and migrate strongly in the winter to the coasts of Southern Asia through Australia, traveling in very large flocks. They lay about four eggs on the ground in a ground scrape. Great Knots migrate over long distances and use a limited number of staging sites during its annual round trip between the breeding grounds of Russia, and the non breeding grounds of Australia....

The Red Knot (Calidris canutus), or Knot in Europe, is a species of bird found in the tundra and Arctic mountains in the far north of Canada, Europe and Russia. North American birds migrate to coastal Europe and South America, while European birds migrate to Africa, Papua New Guinea, Australia and New Zealand. This species has an extensive range and a large population of about 1.1 million individuals. There are six subspecies. The adult is 9 to 10.25 inches in length with an 18.5 to 20.8...
