Alaska Science Forum: High-tech bird decoy fools flycatchers
Julie Hagelin needed a fake bird. She found one in an unexpected place. The biologist for the Alaska Department of Fish and Game is studying the mysterious olive-sided flycatcher, known for its piercing "quick, three beers!" heard above black spruce bogs throughout Alaska. The bird, which weighs as much as a dozen pennies and migrates as far as Bolivia, is declining throughout most of its range in North America. N...

Tracks across Greenland ice, 60 years apart
On top of an ice body more than two miles thick, Chris Polashenski last summer hoped to find a candy wrapper that might have fallen from Carl Benson's pocket 60 years ago. As he repeated the Alaska glaciologist's measurements on the Greenland ice sheet, Polashenski realized that six decades of snowfall, windstorms and glacier movement had wiped out evidence of Benson's passage. "Carl's footprints were entombed in ...

Tracking salmon to their birth streams
Strontium is a trace element and mineral people use to make glow-in-the-dark paints and toothpaste for sensitive teeth. In research for his college degree, Sean Brennan used strontium's unique qualities to track salmon in an Alaska river. At Brennan's Ph.D. defense at the University of Alaska Fairbanks, adviser Matthew Wooller praised Brennan's ambitious plan and his execution of it up and down the many webs of th...

The mystery of 53 dead caribou in the Alaska Range
Forty-two years ago, an Army helicopter pilot flying over a tundra plateau saw a group of caribou. Thinking something looked weird, he circled for a closer look. The animals, dozens of them, were dead. The pilot reported what he saw to the Alaska Department of Fish and Game. The caribou, 48 adults and five calves, were lying in a group. The way their carcasses rested showed no signs that the animals had been runni...

Ever-changing: the number of Alaskan glaciers
A glaciologist once wrote that the number of glaciers in Alaska “is estimated at (greater than) 100,000.” That fuzzy number, perhaps written in passive voice for a reason, might be correct. But it depends upon how you count. Another glaciologist saw an example of the confusion when he visited Yakutat Glacier. Yakutat, near the Alaska town of the same name, is a withering glacier that calves into a deep lake of its...

Arctic Alaska shines in a different light
Slicing through the top quarter of the Alaska map, the Arctic Circle marks the boundary of perpetual light. North of the line, the sun won't set on summer solstice. But somehow the breezy, treeless tundra of Barrow has a more arctic feel than Fort Yukon, also pole-ward of the line but home to dense spruce forests and Alaska's all-time high temperature of 100 degrees. A more "ecologically sound" definition of the A...

Old-growth spruce destroyed at research site
This spring, John Yarie learned of the death of the oldest living things he knew. Since 1988, the silviculture professor at the University of Alaska Fairbanks had measured and fertilized a stand of giant spruce trees on a hillside south of Fairbanks. A few weeks ago, forest technicians visited the site and found that one dozen trees had been cut down, possibly by "wood poachers." "I'm just really disappointed some...

Astronaut recruit: Alaska a good analog for space
Jessica Cherry spends her favorite moments looking at Alaska from above. As a new recruit for a class of astronaut candidates, she may someday view the world from miles higher. Cherry, 37, is a pilot and professor at the University of Alaska Fairbanks' International Arctic Research Center and Institute of Northern Engineering. She flies small aircraft all over the state for fun and research. She is also a member o...

Alaska Science Forum: Woods of Alaska stir after long winter slumber
It’s late May, 118 miles from the Arctic Circle. Time for a walk to work. The season has changed since February, the last time I wrote about walking through the North Campus of the University of Alaska Fairbanks. The North Campus is a rectangle of more than 1,000 acres that begins a few steps south of my door and ends at the university’s multistory research buildings. The spruce-dominated forest, bordered on all s...
