Some primates spend their entire lives in trees. They avoid the ground, where preferred food is scarce and predators lurk. But deforestation and climate change are threatening their homes in…
Scientists analyzed levels of chemical pollutants in native jataí bees across eight landscapes in Brazil’s São Paulo state. They found that in landscapes with more vegetation, the bees had fewer pollutants, at lower levels, indicating that the plants act as a filter and protective barrier
Extinction threatens nearly half of all primate species, largely due to human activities. But alongside them, a hidden world of biodiversity also could disappear: parasites. Using computer modeling, researchers discovered…
Southern right whales, one of the most historically hunted whales globally, have recovered nicely since the whaling era. But a new analysis has shown that El Niño events, which warm…
Cows aren’t too bullheaded or dumb to learn new bathroom habits. Researchers showed this by toilet-training a small group of calves in a toilet they designed and dubbed the MooLoo.…
Tiger sharks sometimes swim thousands of kilometers—far enough to move among oceans. Their flexible diets and adaptable behaviors set them up to be successful jet-setters, zipping around the world and…
From above, the Lhaviyani atoll in the Maldives forms a rough oval, encircling a turquoise stretch of the Indian Ocean speckled with islands. But on the ground, populations of insects,…
Female hummingbirds sometimes look like the brightly colored males of their species. Researchers have long pondered the reason for this. Now, a study of hummingbirds in Panama suggests that sporting…
The jaguar population in Mexico increased by about 800 animals from 2010 to 2018, according to the first two censuses of the elusive carnivores ever conducted in the country. The…
For 20 years, researchers stared at the dark side of the moon to measure its faint but visible “earthshine,” a glow created by sunlight reflecting off Earth and onto the…
Bears, wolves, and other carnivores in Michigan adjust their behavior to avoid active roadways, researchers reported recently in the journal Global Ecology and Conservation. The study is part of the…
Despite living in a concrete jungle, London’s urban bees fly shorter distances to feast on nectar-rich flowers than their neighbors in the countryside—a counterintuitive discovery explained by the many lush…
Every year, growing swaths of the Amazon rainforest are degraded by logging, fragmentation, and human-sparked fires. New research using airplane-based laser scanning of trees shows that degraded forests are hotter,…
Public attitudes in China have shifted substantially to favor stricter regulations on the wildlife trade and a willingness to stop consuming wildlife, researchers reported recently in the Chinese journal Biodiversity…
From underwater tunnels to bridges to communication cables snaking across the ocean floor, structures made by humans are encroaching on marine life at an ever-growing pace. Our physical footprint of…
The COVID-19 pandemic has made it clear that when coronaviruses leap from wild animals to humans, the results can be devastating. A new study from Vietnam provides new insights about…
The Greenland Ice Sheet is losing mass, and there may be no way to stop it, scientists have concluded. Even if large amounts of snowfall return to the ice sheet,…
An analysis of the DNA of three wild dogs living above 4,300 meters (14,000 feet) on the island of New Guinea matches that of captive New Guinea singing dogs. These…
In the arctic tundra of northeastern Siberia lies a graveyard of a now-extinct species of megafauna, the woolly rhinoceros, dating back 50,000 years. Now, a new genomic analysis of the…
Poaching is a pervasive global problem, and iconic mammals like elephants and rhinos are hit hard by illegal hunting. This is especially true in the world’s poorest countries and within…
The Ocean Cleanup is a highly touted nonprofit with the ambitious goal of cleaning up 90 percent of the ocean’s plastic. In reality, the initiative’s impact on the world's floating…
Marine mammals stranded on beaches in the southeastern United States died with high levels of pollutants stored in their organs and blubber, researchers reported recently in Frontiers in Marine Science.…
Like a mermaid on an underwater picnic, she floats gently in the current as slivers of sunlight reveal a garden of corals in the Golfo Dulce, in southern Costa Rica.…
As humans continue to emit record levels of carbon dioxide, we are putting marine habitats at risk. One consequence of these emissions, ocean acidification, is a serious threat to many…
New research shows that without healthy forest corridors that allow animals to find new habitat, primates native to the Amazon basin will suffer as the impacts of climate change worsen.…
Protected lands in the tropics are often managed to curtail poaching, creating a refuge for vulnerable wildlife that face risks of extinction. However, a new study in West Africa’s largest…
Far out in a featureless sea, the light of the moon is a beacon for migrating eels. They’re aiming for coastal estuaries, gateways to freshwater rivers where they will live…
As the Mojave Desert in California and Nevada becomes hotter and drier, birds need more water to stay cool. Species that can’t get enough water are rapidly declining in this…
A delicate balance between beneficial and harmful soil fungi associated with tree roots guides the diverse mixture of tree species that thrive in subtropical forests, according to a new study.…
Salt clearings deep in the Congo basin host numerous breeding groups of Western lowland gorillas (Gorilla gorilla gorilla). These intelligent social mammals usually reside in groups of two to eight…
