A high-country Eden for sockeye salmon

In late summer, a few months before this mossy valley will feel the sting of 40-below air, bright red salmon dart through a crystal-clear pool amid fragrant green vegetation. The Gulkana Hatchery has a Garden-of-Eden feel, which is fitting since millions of sockeye salmon begin life here each year.

Salmon nose deep into Alaska ecosystems

Bonsai trees tell of winters long past

“These are museum-class bonsais,” Ben Gaglioti says as we walk through an elfin forest. Gaglioti, a University of Alaska Fairbanks ecologist, has led me into another landscape I have never seen in Alaska. This terrace of spongy ground above the rainforest is home to trees that Dr. Seuss might have dreamed up.

Rugged science on the Southeast coast

To the woman wearing earbuds and sitting next to me in seat 7E: I’m sorry; I did not get to shower before boarding the plane after 12 days of accompanying four scientists in the hills north of Lituya Bay. I will try to keep my arms pinned to my side and lean toward the window.

His 48th summer on top of the world

This June, George Divoky will refurbish a cabin that sits on a lonely gravel island north of Alaska. He was not planning a remodel this year. Sometime during the winter, a polar bear tore through a plywood wall of the cabin Divoky moved 20 years ago to Cooper Island.

Live-trapping lynx in the far north

Knut Kielland, a professor with UAF’s Department of Biology and Wildlife, used to trap lynx for their fur. Here, he has captured this 22-pound female lynx as part of an Alaska-wide project he leads to better understand the ecology of the animal.

Happenings north of the Arctic Circle

Though the calendar calls it springtime, the thermometer on the truck reads minus 28 F on this sunny morning a few days past spring equinox. I am riding shotgun with Knut Kielland, an ecologist at the Institute of Arctic Biology at the University of Alaska Fairbanks. He has invited me to join him for a week north of the Arctic Circle — 66.6 degrees north latitude, about 150 miles from Fairbanks.

Caribou cams give insight into secret lives

Caribou wearing cameras around their necks have filmed a secret world of mushroom nibbling, desperate head-shaking during bug episodes, and nuzzling of wet newborns seconds after they fall to the tundra.

Listening to the voices of killer whales

Hannah Myers has listened to many hours of orca calls in the Gulf of Alaska. The University of Alaska Fairbanks graduate student often knows a killer whale’s family group after hearing just a few syllables of its call.

Blown back to Alaska, bird perseveres

A bar-tailed godwit recently arrived in New Zealand on its second attempt to get there from Alaska, after a storm had blasted it back north. Keith Woodley of the Pukorokoro Miranda Shorebird Centre on the North Island of New Zealand reported that a male godwit carrying a satellite transmitter first left the mudflats near the Kuskokwim River on Sept. 11, 2021.

Shorebirds depend on wee slivers of Alaska

Pencil-beaked shorebirds with the ability to stay airborne for a week — flying all the way from Alaska to New Zealand — rely on a few crescents of mudflat to fuel that incredible journey.

Scientists recently found that almost the entire population of bar-tailed godwits that breed in Alaska fatten up on clams and worms on ephemeral sand bars just west of the mouth of the Kuskokwim River. In autumn, 80 percent of the birds rest and feed on islands within 15 miles of one another.

Fluorescent bill may be seabird’s neon sign

The crested auklet looks like a smiling clown that never blinks. It is probably the only seabird that smells like a tangerine. Its beak — the color of a tangerine — is so bright a scientist thinks it may be fluorescent.

Setting traps to catch an Alaska virus

On this crisp, cool fall day in 2021, this trapper — who lives in Atlanta and works for the Centers for Disease Control and Prevention — hunts for a virus that was unknown to humans until 2015. That’s when a Fairbanks doctor examined a lesion on a woman’s shoulder.

Pine grove near Yakutat is farthest north

We were on the Yakutat Forelands — a sweep of forested lowlands left behind after glaciers retreated from the landscape hundreds of years ago. Taking steps that felt like walking on a trampoline, we moved through a pine grove in a few-acre spread of open green muskeg.

Visit to glacier begins with wildlife encounter

We heard a loud buzz. A hummingbird hovered in front of my cracker. As I held still, the hummingbird probed the peanut butter, twice, with its needle beak. The cracker transferred the vibration to my left hand, tickling my fingers. As the bird zoomed off, I looked over at Ben to confirm the experience.
“I think you have superpowers now,” he said.

Visit to an exotic tree plantation in Alaska

In 1964, just after Lyndon Johnson swore the oath to follow John F. Kennedy, Alaska forester Les Viereck and others planted tree seedlings at the north end of this old farm field.

White-winged crossbills and yellow snow

By Ned Rozell While out on a springtime snow trail, I recently saw a dozen white-winged crossbills pecking at snow on the side of the trail. When I reached the spot, I saw a yellow stain from where a team of dogs had paused. Last spring, I saw a bunch of crossbills gathered near an outhouse. They were congregated at a communal pee spot in the snow. The birds were …

Bowhead whales: A recent success story

Bowhead whales are true northern creatures, swimming only in cold oceans off Alaska, Canada, Greenland, Svalbard and Russia. These bus-size whales have the largest mouths in the animal kingdom, can live for 200 years and can go without eating for more than a year due to their remarkable fat reserves. Bowheads are also a rare wildlife rebound story, with the population north and west of Alaska now numbering more than 16,000. That’s up from the 1,000 or so animals Yankee whalers left behind in bloody waters at the turn of the last century.

Giant storms, big waves and chilly winds

…the Howard Pass weather station in the western Brooks Range recorded an air temperature of minus 33 degrees Fahrenheit. At the same time, the wind was blowing 47 miles per hour. That’s a windchill of minus 78 degrees. That inhumane condition is not unusual for Howard Pass, a relative low spot (2,062 feet) in Alaska’s farthest-north mountain range.

The northern shrike: songbird like no other

Northern shrikes often jam their prey in forks of trees, or impale voles and birds on a sharp branch, or maybe a strand of barbed wire. Shrikes may store food like this because their feet are more like a chickadee’s than a hawk’s; sticking their food to something helps them tear into it.
