Storm surges in the Yukon-Kuskokwim Delta

“Doing science in the Delta is more than just coming up with interesting questions and implementing them. It also requires a lot of on-the-ground work and pre-season preparation in order to be out here for as long as we are.” A five month field season in remote Alaska is no deterrent to Ryan Choi. “I […]

Wintering Pribilof Rock Sandpiper Science

Rock sandpipers in Alaska videos

“Typically when a bird gets any ice on their body it’s game over.” But not for rock sandpipers overwintering on the mudflats of Cook Inlet, Alaska. Watch new videos about rock sandpipers on FrontierScientists.com featuring science about avian puffballs surviving and thriving despite enduring ice on feathers and feet. Rock sandpipers in Alaska In Cook […]

Starving trees and the boreal forest

“There are many many factors there. And we can only make rational policy decisions if we know how the system works.” Bjartmar Sveinbjornsson is a professor of biological sciences and the director of the Environment and Natural Resources Institute at the University of Alaska Anchorage. He’s hosted two student as part of the National Science […]

Boreal Forest Growth videos released

On FrontierScientists.com, watch new videos featuring Boreal Forest Research in Alaska: ‘Why So Small?‘, ‘How Tree Needles Age‘, and ‘What Are Stomata?‘. “It isn’t just the climate impacting the vegetation but the vegetation impacting the climate,” Bjartmar Sveinbjornsson explained. “As the globe warms up are the forests going to spread and are they going to […]

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 […]

Squirrels’ role in climate change puzzle

Alaska’s North Slope is home to Arctic ground squirrels. Near the Atigun River their interlaced burrow network takes advantage of sandy soil. The burrows are so interconnected and the entrances so myriad that the scientists working there to decode Arctic ground squirrel mysteries carry a map denoting burrow entrance numbers so they can be certain […]

Learning our forests from space– mapping deforestation and regrowth

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 […]

Assisted migration could help plants find a new home

Laura Nielsen for Frontier Scientists – Plants, evolved to move with the natural rhythms of the world, cannot keep up with the rapid pace of climate change we are facing today. Their ideal habitats are sliding north as the world heats up. Do we get our hands dirty and help move the species most at […]

Safeguarding plants in an uncertain climate future

Laura Nielsen for Frontier Scientists – On a remote island in Norway, deep within an old coal mine sealed behind blast doors, seeds sit in the cold and quiet and wait. They are an insurance against an uncertain future. Our uncertain climate future is altering habitats so swiftly that plants can’t keep up, and we’re […]

Wildfires across our hot planet

Laura Nielsen for Frontier Scientists – Wildfires are a hungry, terrible and complex force which we’ve long struggled to live alongside. Smoke and particulate matter from wildfires can travel thousands of miles, lowering air quality and causing health impacts. Local fires risk lives, and fire damage costs millions or more to repair. And now, conditions […]

Humble lemmings are an Arctic keystone species

Laura Nielsen for Frontier Scientists – Arctic temperatures are warming at twice the rate of lower latitudes’, making the area one of the most rapidly changing regions on Earth. Arctic ecosystems are facing radical alteration. And, surprisingly, a tiny furry rodent may be a major player in those changes. Lemming populations have a powerful impact on […]

Bison Bob a big discovery on the North Slope

As she scraped cold dirt from the remains of an extinct bison, Pam Groves wrinkled her nose at a rotten-egg smell wafting from gristle that still clung to the animal’s bones. She lifted her head to scan the horizon, wary of bears that might be attracted to the flesh of a creature that gasped its […]

Bowhead Whale fluke

Triumphs of the endangered Bowhead Whale

Each spring, wildlife biologist Craig George stands where shore-bound sea ice meets open water at Point Barrow and counts whales. Barrow Alaska is the northernmost town in the united states. The lookout point, accessed daily via snowmobile, is no more than a canvas windbreak atop a pile of ice. Warming spring temperatures thin and break […]

Guillemots, and the Edge of the Ice

Laura Nielsen for Frontier Scientists The Bering Sea region hosts over 90% of seabirds breeding in the continental United States. Most of those birds are hardy migrators, breeding on Alaska’s coast in the warm season and then departing south, chased away by the cold weather. One group which remains is Guillemots, a type of seabird […]

Birds Hall Island Alaska

A far-off place, all for the birds

Ned Rozell for UAFGI – HALL ISLAND — On this windy, misty August day, there are perhaps one million birds clinging to the cliffs that buttress this Bering Sea island. These seabirds, crazy-eyed and with bodies both sleek and clumsy, need solid ground for just a few months to hold their eggs. When their summer […]

Scientists identify likely origins of vertebrate air breathing

Marie Thoms for UAF Cornerstone – University of Alaska Fairbanks scientists have identified what they think is the ancestral trait that allowed for the evolution of air breathing in vertebrates. They presented their research at the 42nd annual meeting of the Society for Neuroscience Oct. 17 in New Orleans. “To breathe air with a lung, […]

The longest non-stop migratory flight

LLiz O’Connell for Frontier Scientists – Early on Bob Gill, Research Wildlife Biologist with the U.S. Geological Survey (USGS), thought Bar-tailed Godwits’ journey from Alaska to New Zealand was a non-stop flight. Faced with skepticism from his colleagues, but armed with satellite technology, Gill tagged a female Godwit he named E-7.  By tracking E-7 in […]
