The fur trade halted abruptly with the International Fur Seal Treaty of 1911, which finally forbade commercial harvesting. Hunters and trappers had run rampant during the last two centuries. The species of sea life they harvested for pelts during the 18th and 19th century were decimated: Northern fur seal populations were incredibly rare, and Sea […]
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.
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.
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.
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 […]
The Arctic is blanketed in snow for 9 to 10 months of the year. Then in May or June, with the Sun shining long overhead, snow melt comes sudden. Mathew Sturm, professor of Geophysics, University of Alaska, Geophysics Institute says the world of the Arctic can go from “White to dark in a space of […]
Laura Nielsen for Frontier Scientists – This winter snowy owls were on the move; unusually large numbers of the magnificent birds made their way to the Lower 48 United States. With a wing span greater than four feet and distinctive plumage, snowy owls are a glorious sight. The birds’ winter migrations normally take them to […]
Laura Nielsen for Frontier Scientists – “Every day, Landsat satellites provide essential information for land managers and policy makers to support wise decisions about our resources and environment in the places we live and work.” (NASA) Matthew Hansen, University of Maryland, and co-author Thomas Loveland, U.S. Geological Survey, released an unprecedented record of global deforestation […]

Ned Rozell for UAFGI – Despite taking up as much space as Australia, the blue-white puzzle of ice floating on the Arctic Ocean is an abstraction to the billions who have never seen it. But continued shrinkage of sea ice is changing life for many living things. A few Alaska scientists added their observations to […]
