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

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.
