Greater Yellowstone elk suffer worse nutrition and lower birth rates due to wolves
Wolves have caused elk in the Greater Yellowstone Ecosystem to change their behavior and foraging habits so much so that herds are having fewer calves, mainly due to changes in their nutrition. view more (2009-07-20)
Yellowstone's quiet power
A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought during times when the giant volcano is slumbering. view more (2007-03-01)
Hot springs microbes hold key to dating sedimentary rocks, researchers say
Scientists studying microbial communities and the growth of sedimentary rock at Mammoth Hot Springs in Yellowstone National Park have made a surprising discovery about the geological record of life and the environment. view more (2008-01-23)
Prey not hard-wired to fear predators
Are Asian elk hard-wired to fear the Siberian tigers who stalk them" When wolves disappear from the forest, are moose still afraid of them? view more (2007-06-21)
MSU researchers recommend ways to fight lake trout invasion in Glacier National Park
Natural barriers like waterfalls play an important role in preventing lake trout from spreading through Glacier National Park, so maintaining those barriers should be a priority, Montana State University researchers said after conducting a four-year study in the park. view more (2008-04-25)
Killing wolves may not protect livestock efficiently
Costly and time-consuming efforts to eliminate wolves that prey on sheep, cattle and other domestic animals are ineffective on a long-term, regional scale, according to an examination of wolf control methods in Alberta and several U.S. states by University of Calgary researchers. view more (2006-04-05)
Poison + water = hydrogen. New microbial genome shows how
Take a pot of scalding water, remove all the oxygen, mix in a bit of poisonous carbon monoxide, and add a pinch of hydrogen gas. It sounds like a recipe for a witch's brew. It may be, but it is also the preferred environment for a microbe known as Carboxydothermus hydrogenoformans. view more (2005-12-05)
'Rosetta Stone' of supervolcanoes discovered in Italian Alps
Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale - and possibly trigger climatic and environmental effects at a global scale. view more (2009-09-21)
Shining a light on deep-sea vents: Science meets policy
Scientists first discovered undersea hot springs, known as hydrothermal vents, nearly 30 years ago. These vents, which are among the world's most extreme ecosystems, are found along the ocean ridge, 40,000 miles of underwater mountain range that zig-zags throughout the world's ocean basin. view more (2006-02-21)
Viewing ecosystems from above
"New technology and global observations have improved resource-management decision making from disaster detection and mitigation of fires, insect outbreaks, storms, and floods, to agricultural management and basic ecological research," says Dennis Ojima (Colorado State University). view more (2007-08-07)
Wolf reintroduction proposed in Scottish Highland test case
Researchers are proposing in a new report that a major experiment be conducted to reintroduce wolves to a test site in the Scottish Highlands, to help control the populations and behavior of red deer that in the past 250 years have changed the whole nature of large ecosystems. view more (2009-07-21)
New cell division mechanism discovered
A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. view more (2008-10-28)
Big quakes spark jolts worldwide
Until 1992, when California's magnitude-7.3 Landers earthquake set off small jolts as far away as Yellowstone National Park, scientists did not believe large earthquakes sparked smaller tremors at distant locations. view more (2008-05-27)
Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. view more (2008-05-23)
Cornell conservationists propose allowing wild animals to roam parts of North America
If Cornell University researchers and their colleagues have their way, cheetahs, lions, elephants, camels and other large wild animals may soon roam parts of North America. view more (2005-08-18)
Earthquake swarms not just clustered around volcanoes, geothermal regions
An earthquake swarm - a steady drumbeat of moderate, related seismic events - over hours or days, often can be observed near a volcano such as Mount St. Helens in Washington state or in a geothermal region such as Yellowstone National Park in Wyoming. view more (2006-10-26)
Early life on Earth may have developed more quickly than thought
The Earth's climate was far cooler - perhaps more than 50 degrees - billions of years ago, which could mean conditions for life all over the planet were more conducive than previously believed, according to a research team that includes a Texas A&M University expert who specializes in geobiology. view more (2009-11-12)
Are wolves the pronghorn's best friend?
As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope. view more (2008-03-04)
Mountain caribou's ancient ancestry revealed
The declining mountain caribou populations of Canada's southern Rockies are a more distinct breed than scientists previously believed, according to a new study by University of Calgary researchers that is shedding light on the ancient ancestry of the mountain-dwelling herbivores. view more (2009-01-29)
Fledgling mantle plume may be cause of African volcano's unique lava
Nyiragongo, an active African volcano, possesses lava unlike any other in the world, which may point toward its source being a new mantle plume says a University of Rochester geochemist. view more (2009-03-13)
