The popularity of grass-fed beef owes much to the claim that the meat from cattle raised on pastures is superior to corn-fed beef. Many people may feel better knowing they…
Amazonian rainforests bustle with activity: Monkeys snag fruit from branches in the canopy; peccaries root around in the topsoil for grubs, worms and plants; a jaguar feasts on the carcass…
Rivers in the Amazon are cycling between increasingly severe states of flood and drought, as predicted by climate change models, and the results are directly impacting local wildlife and the…
Think of the illegal wildlife trade, and elephant tusks and rhino horns come to mind. But another of the world’s largest land mammals is slipping under the radar: the common…
As plastic debris drifts through the ocean, it accumulates a coating of algae and bacteria. That coating smells delectable — that is, if you’re a fish. Northern anchovies (Engraulis mordax)…
The moon rides high over the Bolivian Amazon as the Tsimané people crowd around the fire to tell stories. A conservation scientist sits among them, leans in to catch every…
A plant without water will wither and, eventually, die. This is easy to observe in the browned leaves of a neglected houseplant, but what happens when an entire forest gets…
Sperm whales wander great expanses of the sea, locking their culture between their lips and carrying it with them wherever they go. Their distinctive vocal traits allowed researchers to identify…
Humans aren’t the only primates who jockey for higher social status and the rewards that go with it. Chimpanzees also compete for higher rank within their communities, and the accompanying…
Rainforest cover in the Indonesian archipelago has declined rapidly in recent years giving way to large-scale plantations of rubber and oil palm. Now a recent study published in Nature Communications…
The loyalty of humpback whales to their annual feeding grounds in Glacier Bay and Icy Strait, Alaska, is passed down from mothers to their calves, marine biologists have shown. Understanding…
At first glance, grasslands may look like monotonous stretches of green or gold. But closer inspection reveals a bounty of diverse grasses, clovers and wildflowers coexisting within small areas. These…

Compounds from our makeup and bathrooms are winding up in the bodies of dolphins, sea otters, and polar bears – sometimes thousands of miles away. For the first time, research…
Amphibians occupy almost every ecological niche, from the highest tropical trees to the most fetid pools of desert water. Brightly colored and cryptically camouflaged, they have evolved an astounding array…
Visitors to the tropics remember the bright colors. Take the blue-and-yellow macaw with its egg-yolk breast and turquoise back – “the usual gaudy colouring of the intertropical productions,” as Charles…
A hodgepodge of laws protects roughly 15 percent of Earth’s land, but safeguards for the ocean lag behind. Today, laws shelter a meager 3.6 percent of the planet’s liquid blue…
At a time when wildfires around the world are burning through records for intensity and size, several western U.S. ecologists argue that in many forests our best hope is to…
Invasive species are great hitchhikers. They float in the ballast of ships, lurk in luggage, stick to unwashed sports gear, and cling to the soles of hiking boots. Scientists focus…
Ask anyone dangling a rabbit’s foot from their keychain what the severed appendage is for, and they’ll tell you it brings good fortune. Ask a traditional healer in West or…
