The Japanese project is known as SEEDS (Subarctic Pacific Iron Experiment for Ecosystem Dynamics Study), an ongoing eff...

Ecological destruction fuels emerging diseases

...diversity. In the Guanacaste Conservation Area of northwest Costa Rica, a 1,000 square km (400 square mile) United Nations World Heritage Site that features habitats ranging from rain forests to savannas, the ATBI is documenting an estimated 250,000 species of plants and animals, including everything from vir...

Study Links Ebola Outbreaks To Animal Carcasses

...d in the region straddling northeast Gabon and the northwest Republic of Congo. Of these carcasses, 21 gorilla, chimp and duiker carcasses were tested for the Ebola virus, with 14 samples being found positive. In 11 cases, instances of human infection were directly linked to gorilla, chimpanzee and duiker carc...

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...Richmond Mine in Iron Mountain, Calif., nine miles northwest of Redding and one of the largest Superfund sites in the country. She hopes to understand how the organisms live together and interact with minerals to produce the hot, heavy-metal rich and highly acidic water that drains from the mine and contaminat...

NRL scientists detect 'milky sea' phenomena

...at least three nights. The event took place in the northwest Indian Ocean, approximately 280 km off the Somali coast. The boundaries of the feature matched closely with a surface ship's reported entry and exit of the brightly glowing waters. Although such observations cannot be fully explained based on the k...

The researchers included 45,478 randomly selected people in the district to answer screening questions about exposure to poultry and flu-like ill...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

...e Centre as part of a larger register covering the northwest Atlantic, from the Arctic to Cape Hatteras (North Carolina). The scope of life forms ranges from microscopic plants to marine mammals in waters from the lower intertidal to the deep sea. Researchers at the Huntsman, led by curators Lou Van Guelpen a...

Crucial site for endangered frogs and birds saved

...a stepped in to protect the 1,600-acre site on the northwest slope of the Sierra Nevada de Santa Marta massif, on the Caribbean coast of Colombia, before its development for vacation homes. The site is the sole breeding ground for the Globally Endangered Santa Marta Parakeet. Another 18 bird species and five ...

Albatross study shows regional differences in ocean contamination

...st of North America, while Laysan albatrosses head northwest toward the northern and western regions of the North Pacific. Black-footed and Laysan albatrosses both consume a mixed diet of squid, fish, and fish eggs. Finkelstein analyzed nitrogen isotope ratios in the two species--an indicator of an animal's ...

Healthy coral reefs of Madagascar resisting damage from climate change

...ned with results of a similar survey in 2002 along northwest Madagascar's coast, increased to 829 the total number of fish species in Malagasy waters. The two Rapid Assessment Program (RAP) expeditions also recorded the highest coral diversity of the western Indian Ocean and the Red Sea, making the region one ...

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

... Dorado Nature Reserve established in March on the northwest slope of the Sierra Nevada de Santa Marta massif, on the Caribbean coast of Colombia.

Ebola-outbreak kills 5000 gorillas

...ividually known gorillas at the Lossi Sanctuary in northwest Congo were killed by Ebola during outbreaks in 2002 and 2003. They then used transect surveys to show that 95% gorilla mortality rates extended over a much larger area of several thousand square kilometres. Chimpanzees were also heavily affected, wit...

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

... to show rapid declines in the great sharks of the northwest Atlantic since the mid-1980s. Now, by examining a dozen different research surveys from 1970-2005 along the eastern U.S. coast, the research team has found that their original study underestimated the extent of the declines: scalloped hammerhead and...

Ocean's 'twilight zone' may be a key to understanding climate change

...light zone off Hawaii, while 50 percent did in the northwest Pacific near Japan. These sinking particles, often called "marine snow," supply food to organisms deeper down, including bacteria that decompose the particles. In the process, carbon is converted back into dissolved organic and inorganic forms tha...
