With dogs’ breath fogging the 30-below zero air at their knees, 71 Iditarod mushers steamed their way down the frozen Chena River in Fairbanks on March 6. Upstream, just a few miles behind them, 500 ducks were surviving in a one-mile stretch of open water.

“My wife saw a lynx out there, sitting next to the chicken coop like a lion, twitching its tail and looking at the chickens and ducks,” said Ralph Lohse, who lives with his wife Linda on property between the Edgerton Highway and the Tonsina River. They watched the lynx for 40 minutes, until it leapt to webbing on top of a chicken coop.

Bada found that most of the adult whales were between 20 and 60 years old when they died, but five males were much older. One was 91, one was 135, one 159, one 172, and the oldest whale was 211 years old at the time of its death. That whale was gliding through the Bering, Chukchi and Beaufort seas when Thomas Jefferson was president.

Achyut Tiwari relates how he and his colleagues endured everything from a drunken porter to huge dogs, dizzying mountain trails and even a landslide to conduct their field work in Nepal. His research is on climate responses in treeline dynamics and growth climate in central Himalaya and Hengduan mountain, China. Tiwari is originally from Nepal and is affiliated with Xishungbanna Tropical Botanical Garden, Chinese Academy of Sciences.

One of the many tools birds use to migrate — besides the metal bits in their heads that help them sense Earth’s magnetism — is their ability to use infrasound. Infrasound consists of frequencies too low for us to hear. The aurora, volcanoes, underground nuclear detonations, and stormy seas emit infrasound waves. “Birds flying over the Rockies can hear the surf of both the Atlantic and Pacific,” Sharbaugh said.
