Aspen Recovery in Yellowstone Spurred by Wildlife Shifts
Wildlife in Yellowstone National Park is undergoing dramatic shifts with consequences that are beginning to return the landscape to conditions not seen in nearly a century. In the park’s northeast section, elk have decreased in number in their historic winter range in the Lamar Valley and are now more numerous outside the park.
Oceanography Boot Camp
The marine reserve off Cape Perpetua served as a laboratory for Oregon college students in April 2014.
Taking the Measure of Seals and Those Who Study Them
In Antarctica, when you sedate a 1,000-pound Weddell seal, it can take a while for the animal to settle down.
Forests at Risk
“The margin between life and death in the forest can be rather small,” says Oregon State climate scientist Philip Mote. As wildfires widen, insects invade and drought deepens, the razor-thin margin for tree survival becomes ever thinner.
An Iceberg Roars
OSU scientists were astounded recently when they listened to recordings of an iceberg that had formed in Antarctica, floated into the open ocean, and eventually melted and broke apart. Scientists have dubbed this phenomenon an “icequake.”
Through the Ice
Andrew Thurber is a self-described “connoisseur of worms.” He finds these wriggling, sinuous creatures, many with jaws and enough legs to propel an army, to be “enticing.” In the Antarctic, where he dives through the ice in the name of science, a type of worm known as a nemertean can reach 7 feet long.
