A new study gives insight into the strange breeding behaviour of banded stilts. These water birds fly thousand of kilometres to nest in temporary desert salt lakes.

Bringing back aurochs is a competitive and ambitious venture aiming at recreating wilderness in Europe. But ethical and scientific questions linger.
Unlike napalm, which immediately scalded its victims, Agent Orange kills and maims slowly over time, its effects passed down through generations.

The use of Agent Orange in Vietnam had deep impacts, including a poisoned water supply, birth defects and cancer. Despite decades of attempted litigation, justice for spraying victims seems unlikely.
A brown bear snags a sockeye salmon in Alaska. In warm years, red elderberries ripen early and Kodiak bears leave streams full of salmon to eat them.

Climate change is making berries ripen early in Kodiak, Alaska, luring bears away from eating salmon. This shift may not hurt the bears, but could have far-reaching impacts on surrounding forests.
A drain carries water but does little else, but imagine how different the neighbourhood would be if the drain could be transformed into a living stream.

Drains take up precious but inaccessible open space in our cities. Converting these to living streams running through the suburbs could make for healthier places in multiple ways.
It was all the apple’s fault: we’ve been fascinated by poisoned fruit for a long time.

For mapping patterns of plant invasion from the sky, understanding plant behaviour on the ground and using it along with remote sensing cameras, is crucial.
Hey, what about us? Whale shark (spotted) and manta ray, a close shark relative.

As the Discovery Channel and National Geographic Wild unleash a week of dueling shark programs, a biologist advises viewers to take what they see with a large grain of sea salt.
In an urbanizing world, people increasingly are seeking out nature in cities. Research shows that diverse species of animals, plants and insects can thrive in areas that humans have altered.
A National Park Service staffer applies herbicide to invasive honeysuckle along the Natchez Trace Parkway.

Most of the earthworms in the US Northeast and upper Midwest are nonnative species. Scientists are finding increasing evidence that invasive worms and invasive plants may help each other.
Partula snails were driven to extinction in the wild by introduced predators.

The “decision science” approach helps avoid unanticipated consequences of programs to bring species such as New Zealand’s little bush moa, Waitomo frog, or laughing owl back from extinction.
The Trump administration will review the status of The Bears Ears National Monument in Utah, one of the country’s most significant cultural sites.
Bureau of Land Management
Trump wants to scale back national monuments on federal lands in the name of boosting the economy. But this would undo decades of investments to manage our cultural and ecological resources.

Sea otters had been absent from this Alaskan national park for at least 250 years. By marrying math and statistics, scientists map this animal’s successful comeback.
