Horseshoe Crab Behavior Impacted By Biomedical Bleeding
2014-02-26 06:56:44

University of New Hampshire DURHAM, N.H. – New research from Plymouth State University and the University of New Hampshire indicates that collecting and bleeding horseshoe crabs for biomedical purposes causes short-term changes in their behavior and physiology that could exacerbate the crabs’ population decline in parts of the east coast. Each year, the U.S. biomedical industry harvests the blue blood from almost half a million living horseshoe crabs for use in pharmaceuticals —...

Extinct Arthropod Had Big Claws Spider Brain

Brett Smith for redOrbit.com - Your Universe Online While finding an intact fossil of any kind can be an exciting discovery, an international team of paleontologists recently discovered the earliest known complete nervous system in the fossil of a never-before described creature that crawled or swam in the ocean some 520 million years ago, according to a report in the journal Nature. The researchers said the fossil belongs to an extinct group of marine arthropods known as megacheirans,...

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...

Death March Recorded In Fossil
2012-09-10 04:27:43

Brett Smith for redOrbit.com - Your Universe Online An unusually complete fossil unearthed in Bavarian Germany was found to depict the tragic last moments of a prehistoric horseshoe crab as it stumbled for its life over 150 million years ago. The crab´s fossilized track, which is over 31 feet in length, displays both the beginning and end of its death march that was the result of the arthropod falling into a stagnant lagoon, according to a recent report published in the journal...

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...

Liquid crystal droplets could replace horseshoe crab blood in common endotoxin test The Food and Drug Administration requires every drug they certify to be tested for certain poisons that damage patient health. The current gold standard for this is the limulus amoebocyte lysate (LAL) assay that involves using the blood of horseshoe crabs, which strangely enough is blue, to test for endotoxin, a substance commonly associated with many symptoms caused by bacterial infections. But researchers at...

Experiments by a team of researchers in New York and New Jersey have generated evidence that questions the common belief that the pterygotid eurypterids ("sea scorpions") were high-level predators in the Paleozoic oceans. This group, which ranged the seas from about 470 to 370 million years ago (long before the dinosaurs appeared), included the largest and, arguably, scariest-looking arthropods known to have evolved on planet Earth. Reaching lengths of 2 ½ meters with a...

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....

Having survived for more than 400 million years, the horseshoe crab is now under threat "“ primarily due to overharvest and habitat destruction. However, climatic changes may also play a role. Researchers from the University of Gothenburg reveal how sensitive horseshoe crab populations are to natural climate change in a study recently published in the scientific journal Molecular Ecology. The horseshoe crab is often regarded as a living fossil, in that it has survived almost unchanged...

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...

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...
