Challenging times are ahead for smaller, lighter-colored butterflies as Earth’s climate continues to warm, a new study has found.
Unlike their relatives with larger wings and darker colors, small butterflies with paler hues — particularly those belonging to the Lycaenidae family — have trouble regulating their body temperatures as the air temperature increases, according to the research.

What we can learn from creative city initiatives, from Sydney to Paris.
What makes a city great? Whether you’re living in Durban, South Africa, or Medellín, Colombia, perhaps no two people living in one place will have the same answer. But ask residents across different cultures and regions about challenges facing their own cities, and common issues will emerge, like the need for more affordable housing, better public transportation and access to resources and services.
With rain hitting the roof, the temperature outside hovering in the low 50s and a cast iron stove keeping things warm inside the cabin that, on this July weekend, is serving as an art studio and classroom, I feel a nap coming on. Summer days in Alaska. They are not always the bluebird skies promised in travel ads.
But there’s no time for napping on this trip to McCarthy, a bustling summer community of artists, writers, seasonal workers and visitors that sits 60 miles down a gravel road in Wrangell-St. Elias National Park & Preserve.
I’m here to expand the techniques I use to observe and record the natural world, to gain a deeper understanding of the animals, plants and geology of the state I’ve called home for eight years. Over the next two days I’ll attend a field-sketching workshop taught by the science illustrator and natural history artist Kristin Link through the Wrangell Mountains Center.
To accompany a photo spread shot by Kiliii Yuan, this short piece details travel to and around Alaska's Gates of the Arctic National Park.

Denali National Park doubles as an immersion course in the cultures, landscape and wildlife of interior Alaska.
Along with Denali herself, a 20,310-foot stunner swaddled in snow and ice, the 4.74 million-acre park houses many of the Alaska Range's other famed mountains, including Mounts Foraker and Hunter. You'll also take in braided rivers carving out new paths, glaciers and wildlife: Bears (both black and grizzly), caribou, Dall sheep, moose and wolves roam these wild acres, as do 160 species of birds, including regal bald eagles, northern hawk owls and Swainson's thrushes.
Denali is no tame Disneyfied experience; your first bear sighting will zap any notion of that. Yet, no matter your level of comfort in the great outdoors, you'll find your place here.
Read the rest of my guide to Denali National Park on the AARP website.
One of the Northwest Boreal Lynx Project’s star travelers, nicknamed Hobo, was radio-collared in Alaska’s Tetlin National Wildlife Refuge in March 2017, just over the border from the Yukon. The lynx took off from his home range in June 2017, and, by July 2018 had traveled a whopping 2,174 miles, across mountains and often powerful rivers.
“That was the first one that really took off. We had inklings of this, but we didn’t really know too much about it,” says Knut Kielland, a professor of ecology at the University of Alaska Fairbanks’ Institute of Arctic Biology. It “was pretty exciting.”
Even for an experienced tundra traveler like photographer Kiliii Yüyan, the 13,238-square-mile Gates of the Arctic National Park & Preserve—which sits in the Alaskan interior, above the Arctic Circle—can be hard to picture.
“I think there’s this sense that the Arctic is a vast, barren plane,” says Yüyan. But the park, which protects parts of the 600-mile-long Brooks Range, is ridged with “incredibly photogenic and majestic” mountains unlike the coastal plains that make up most of the Arctic. “You’re in a true wilderness.”
Standing on a beach in late May 2018, surrounded by her team members and gear, Laura Stelson thought, “What have I gotten myself into?”
An archaeologist who started working for Katmai National Park & Preservetwo years earlier, Stelson was about to lead a four-week expedition, retracing historic routes by a National Geographic explorer in the 1910s. The modern-day expedition’s goal was to find and manage evidence of the trips a hundred years ago as well as the populations that had lived in the area before it was forever changed by a massive volcanic explosion. Stelson’s expedition would cover at least 200 hiking miles, using eight different base camps along the way.
