Researchers appeal for new regulations to save coral reefs from live fish trade

...erating pace, starting at 100 km per year from its coast in the 1970s, to reach over 400 km per year in the 1990s. However, the scientists say the strongest argument for balancing international trade and local needs is the social inequity that arises from the export of the dwindling coral reef resources ...

Record air pollution above the Arctic

... AWIPEV-Research base in Ny-Ålesund at the western coast of Svalbard. However, at the beginning of May it turned to a deep orange-brown. Confirming the observations of the German team, Swedish scientists of the Department of Applied Environmental Science at Stockholm University (ITM) measured up to fifty m...

Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs

...rra Nevada de Santa Marta massif, on the Caribbean coast of Colombia. The reserve is an important home for threatened species, and its protection was a top priority of the Alliance for Zero Extinction ?a 62-member group of conservation organizations battling global extinctions. In March, alliance members ...

Mobile DNA part of evolution's toolbox

...il a live specimen was caught in 1938 off the east coast of South Africa. The coelacanth is a descendant of the ancient marine organism that gave rise to the terrestrial vertebrates more than 360 million years ago. Humans are therefore separated from the coelacanth by hundreds of millions of years of evolu...

Study: Living coral reefs provide better protection from tsunami waves

Researchers barcode DNA of Venice museum's vast fungi collection

... that has caused widespread dieback of tanoaks and coast live oaks in California and southwest Oregon. "In the case of exotic plant diseases, DNA information may be used, as it is in criminal forensics, to identify possible culprits and to understand how they were introduced," said Garbelotto. "This pro...

Microbe fixes nitrogen at a blistering 92 C

...at Axial Volcano on the Juan de Fuca Ridge off the coast of Washington and Oregon. Fixing nitrogen at 92 C smashes the previous record by 28 C, a record held by Methanothermococcus thermolithotrophicus, an archaeon that was isolated from geothermally heated sand near an Italian beach and fixes nitrogen at ...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...d trees in the western U.S., native to the Pacific coast from San Diego to Alaska. The sequenced DNA was isolated from a specimen collected along the banks of the Nisqually river in Washington State. The poplar project supports a broader DOE drive to accelerate research into biofuels production, under the...

Small, smaller, smallest -- The plight of the vaquita

... thought ?confined to a small area off the eastern coast of the Baja California Peninsula. What is driving the vaquita towards extinction" It is not, as is so often the case, degradation of its habitat. A risk factor analysis discounted pollution or the drastic reduction of freshwater flow from the Colo...

Finding an answer to Darwin's Dilemma

...ms between layers of sandstone on the southeastern coast of Newfoundland. This pushed back the age of Earth’s earliest known complex life to more than 575 million years ago, soon after the melting of the massive "snowball" glaciers. New findings reported today shed light on why, after three billion years ...

Researchers link ocean organisms with increased cloud cover and potential climate change

...ns seen over a large area of ocean off the eastern coast of South America. Using complex numerical models, they estimated that the resulting increase in cloudiness reduced the absorption of sunlight by an amount comparable to what has been measured in highly polluted areas of the globe. If confirmed ...

Hundreds of thousands of viral species present in the world's oceans

...l, they saw that samples from the British Columbia coast were the most genetically diverse (consistent with its nutrient-rich environment). The other three samples showed increasing diversity with decreasing latitude, a trend that parallels previous findings from terrestrial ecosystems. In fact, the resear...

Endangered shortnose sturgeon saved in Hudson River

...s in large rivers and estuaries along the Atlantic coast of North America, has increased by more than 400 percent in the Hudson River since the 1970s, report Mark Bain, associate professor of natural resources at Cornell, and his colleagues in the online publication PLoS ONE. However, the shortnose sturgeo...

The findings were reported...

Meat and two neutrons -- the key to a longer life

...d by 10%, which, with humans expected to routinely coast close to the centenary, could add a further 10 years to human life. Food enhanced with isotopes is thought to produce bodily constituents and DNA more resistant to detrimental processes, like free radical attack. The isotopes replace atoms in su...

How to manage forests in hurricane impact zones

"Coastal areas in the southern United States are adapted to disturbance from both fire and high wind," says Stanturf, project leader of the SRS disturbance ecology unit based in Athens, GA. "But those adaptat...

Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward

...e in sea ice." A decrease in sea ice along the coast shows a drop in krill in the marine environment. As a major food source for higher animals, the loss of krill will reduce resources for higher mammals and birds. Data gained through the Long-Term Ecological Research (LTER) site near the American ...

Saving endangered whales at no cost

...ation of about 350 individuals remains on the east coast of North America. A leading threat to the species is lethal entanglement by fishing gear: Photographic evidence indicates that 75% of individuals show signs of entanglement, mostly from lobster fishing gear.
