“Insects are like a glue that holds ecosystems together,” said researcher Derek Sikes, who is studying populations in Alaska’s boreal forests.
In its second mission, the Healy is scheduled to carry early career scientists on a cruise through the Northwest Passage to Greenland.
Warm conditions in northern seas must match to allow salmon to swim that far, a convergence likely to be more common with climate change, scientists say
Science writer Ned Rozell was joined by two friends on a 33-hour trek from Eagle Summit to the Chena Hot Springs Resort.
Ancient people might have used sea ice as a bridge to “coastal areas and islands with a relatively traversable surface that doubled as a platform for hunting energy-dense marine mammals,” according to a recent study.
Horticulturists and animal breeders today carry on the same type of experiments Charles Georgeson did 100 years ago, finding species of plants and animals capable of adapting to the Far North.
Climate change is likely causing dozens of rivers in Alaska to flow orange, and it could be disastrous for the state, researchers say.
While international phaseouts and bans of persistent organic pollutants show positive effects, levels of unregulated contaminants are on the rise in some regions.
Science writer Ned Rozell is joined on trip into the woods to investigate a peculiar hole in the ground he had noticed on dog walks.
A study sampling microplastics across the state is discovering where they are the most concentrated, with some clues as to why.
A recent paper reported avalanches killed between 23% and 65% of all the collared animals that had died during the 17 years biologists had followed them.
More than 250 stations make up Alaska’s seismic monitoring network. Each presents its own challenges.
A pair of UAF engineering students will try to collect samples every 2,000 feet on Denali, in an effort to determine if the tiny plastic particles are as abundant there as they are elsewhere on Earth.
Researcher Ben Jones found working tools — several paddles and a spear with a stone tip — within the Lost Jim Lava Flow on the Seward Peninsula.
When the ice retreats it causes them to fragment into smaller bodies of ice, establishing more glaciers.
Astrophysicists Lindsay Glesener and Sabrina Savage wait for the conditions to be ideal before launching a pair of rockets loaded with testing instruments into the atmosphere.
Researchers want to use the ultrafine rock particles left by eroding glaciers to suck climate-warming carbon from the air.
Kunali was delivered from the Alaska Zoo in Anchorage to Fairbanks, where its skin, tissue and bones will aid scientists in the future.
An expert in space physics at the UAF Geophysical Institute, Peter Delamere finished third in the Iditarod Trail Invitational 350 bike race.
In the far north, where night will soon be in short supply, nocturnal animals like flying squirrels and owls need to go about their business in daylight.
None of the four members of the Salty Science team had rowing experience, but they managed to win the World’s Toughest Row women’s division after crossing more than 3,000 miles of ocean.
A wide-ranging research program led by a UAF ecologist is tracking the way beavers’ northward movement affects permafrost, water quality, fish, birds and communities.
One Alaska geologist’s explanation: With a lack of the freeze-thaw process that other mountains experience, Denali doesn’t erode as quickly as others.
