Sea otter UAV health checkup

Spying on sea otter activities lets biologists measure populations of other species in the otters’ habitat. “It’s just a lot of work to get densities of clams and marine species like that,” described wildlife biologist Daniel Monson. To get a better idea of ecosystem health, scientists can use Unmanned Aerial Vehicle (UAV) technology to take […]

Polar bears respond to sea ice habitat loss

Sea ice is a polar bear conveyor belt

“It’s very difficult to observe polar bears directly in their environment.” “They travel widely,” George Durner, research zoologist with the United States Geological Survey Alaska Science Center, explained the bears travel “Hundreds of thousands of square kilometers in the course of the year across the sea ice environment.” To enter the polar bear world Durner […]

In new videos Hair Reveals Diet and In the Eyes of the Polar Bear, Frontier Scientists features current polar bear research. Scientists Todd […]

Where are the nests migratory bird science

Fitness for birds in warming Alaska

Jonathan Perez stands in a remote part of Alaska’s North Slope while White-Crowned Sparrows sing from surrounding shrubs and a Jaeger flies overhead, calling. Perez is listening to the bird calls, recording what species sound out and how many individuals are singing. Next to him, an automated device is attempting to do the same.

Imaging the future of Arctic plant life

If you know where to look in the Arctic, you’ll find strange hexagons dotting the tundra beneath the enduring summer sun. Strange, scattered honeycomb chambers. The open-top hexagonal units shelter 1 or 2 square meters’ worth of tundra plants, passively raising the temperature within their fiberglass walls by 1-3°Celcius.

Migration Over The Brooks Range

Even Wacky Weather doesn’t stop bird migration to Alaska. Scientists on the north side of the Brooks Range at Toolik Field Station find the birds which made it over the mountains have located their nests, indicating procreation has begun.

Alaska research insects vacuuming

Mosquito netting, vacuum power, and bug science

Vacuuming at home isn’t too edifying. How about vacuuming the Alaska tundra to snag a bag full of bugs? That’s an entirely different story. Ashley Asmus, graduate research assistant at the University of Texas at Arlington, is using a huge reverse leaf blower to collect the bugs she’ll study.

Longspur capture bird

Stressed out? Every year migratory birds battle stress, and win

On the tundra a wire walk-in trap has been placed over seed scattered atop icy Alaskan ground. A Longspur alights nearby. It twists its head to eye the seed, hops inside then briefly flaps – unsettled by the trap door closing behind it. The Longspur settles and eyes the ground again, beginning to peck. PhD student Jesse Krause, a researcher […]
