Pogonomyrmex barbatus harvester ants have been observed making regular visits to the nests of much smaller ants, which groom these larger visitors. This behavior represents the first known example of mutualism between different ant species, showcasing the intricate social dynamics within ant communities.

Caine's book explores the ways of life in Chillca, a small community on the flanks of Mount Ausangate in Peru, 14,000 feet above sea level. In this village of 350 people, women are the primary pastoralists, tending to herds of alpacas, llama and sheep.

"It was so emotional and meaningful for everybody. [There] was like an excitement. But it was also super sorrowful at the same time," said Best.

California's Sierra snowpack peaked at only 73% of average on February 25, 2026, and has since diminished. The Northern Sierra recorded just 10% of normal snow levels by mid-April.

Noor, meaning light in Arabic, is a solar facility that produces enough energy to power more than a million homes, utilizing concentrated solar power instead of traditional PV panels.

Indigenous communities have seen dramatic changes, from rescinding land-management policies that were more inclusive of Indigenous knowledge to reducing $1.5 billion in climate funding for tribal initiatives.

Western Sahara is the largest disputed territory in the world, designated by the United Nations as a non-self-governing territory, despite Morocco controlling about 80% of it.

The Wasteland Nomad is built from biochar and seeds of indigenous plants, which are both biodegradable materials. Biochar works like a sponge inside the soil, as it holds water, gives microbes a surface to live on, and locks carbon into the ground instead of letting it escape into the air.

Before state Route 62 was built, there was seamless 95-mile-long habitat connectivity between the San Bernardino and Little San Bernardino mountain ranges, extending from the I-10 south of Joshua Tree National Park to the I-15 near the Cajon Pass. Now, plans for two new wildlife crossings across the highway aim to bring back some of that connectivity, while potentially saving a local population on the brink of extinction in the process.

In Turkana, the land is rugged, roads disappear into dust, and villages are scattered across vast distances in a county of just more than a million people. Despite it being the rainy season, weather experts warn that Turkana and other arid regions may receive little relief. Authorities say drought is once again taking place, with 23 of Kenya's 47 counties affected.

As a SoCal resident, I visit Anza-Borrego at least once a year to explore the sandstone Slot canyon and surrounding desert, keeping an eye out for animals like chuckwalla lizards and bighorn sheep. Despite its incredibly dry environment (the park averages just four to eight inches of rain a year, and summertime temps routinely hit the hundreds), Anza-Borrego teems with life and opportunities to explore one of the nation's most unique ecosystems.

In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.

The Colorado River is an interconnected system, sustained by Rocky Mountain snowpack, rainfall and groundwater. It is fragile, and under increasing stress. Two and a half decades into this century, the river that built the modern West has 20% less water flowing through it than it did on average in the last century. As heat and drought intensify, so do the stakes: Failure to recognize the severity of changing conditions, managing the river in parts without considering needs of the whole and inadequate planning for long-term shortages put the future of all the basin at risk.

Over time, the water evaporated to form the smaller, brinier Owens Lake. Indigenous Paiute people call the Owens Valley Payahuunadü, 'the land of the flowing water'. Today, Owens Lake is a 'Dusty Vestige of the Old West', as NASA described a photograph of the lake taken from space.

Because we're homeotherms, we assume all mammals work the way we do. But in recent years, as improvements in technology allowed researchers to more easily track small animals and their metabolisms in the wild, we're starting to find a lot more weirdness.

Western water law is based on the prior appropriation doctrine, which gives the first entity to make "beneficial use" of water the right to keep on using that amount, even if that means that upstream "junior" users' spigots will get shut off. By the early 1900s, a rapidly growing California was enthusiastically diverting the Colorado River, with huge irrigation districts gobbling up the senior water rights.
