    1 million species are under threat. Here are 5 ways we speed up extinctions

    Stories about individual species on the brink of extinction may be all too familiar. But a new tally now reveals the breadth of the conservation crisis: One million of the world’s species are now poised to vanish, some as soon as within the next few decades.

    That number, which amounts to 1 in every 8 animal or plant species on Earth, comes from a sweeping new analysis of about 15,000...

    War wrecked an African ecosystem. Ecologists are trying to restore it

    The national park at the southern end of Africa’s Great Rift Valley was once considered a wildlife paradise. Hippopotamuses lolled in the lush waters of Mozambique’s Lake Urema, and thousands of antelope bounded across the park’s savannas and floodplains. Elephant herds and prides of lions drew international tourists.

    Then civil war erupted in the southeast African nation in 1977,...

    Pandas’ share of protein calories from bamboo rivals wolves’ from meat

    Giant pandas eat bamboo like a wolf in vegan clothing.

    In the wild, pandas devour massive amounts of bamboo and digest it so efficiently that protein from the plants probably supplies at least half of the animals’ calories, a study finds. That’s about on par with measurements of how many calories from protein make up the carnivorous diets of wolves and feral cats, conservation biologist...

    How a tiger transforms into a man-eater

    No Beast So FierceDane HuckelbridgeWilliam Morrow, $26.99

    At the heart of No Beast So Fierce is a simple and terrifying story: In the early 20th century, a tiger killed and ate more than 400 people in Nepal and northern India before being shot by legendary hunter Jim Corbett in 1907. Rather than just describe this harrowing tale, though, author Dane Huckelbridge seeks to explain how...

    Human encroachment threatens chimpanzee culture

    From deep inside chimpanzee territory, the fieldworkers heard loud bangs and shouts. Hidden video cameras later revealed what the chimps in the Boé region of Guinea-Bissau were up to. Males were throwing rocks at trees and yelling.  

    Researchers don’t fully understand why the apes engage in this rare behavior, known as accumulative stone throwing. And scientists may not have much time to...

  • 50 years ago, DDT pushed peregrine falcons to the edge of extinction

    Fierce and swift, steel blue in color and called the world’s most perfect flying machine, the peregrine falcon is heading toward extinction in North America. The reason: DDT. Perilously high levels of the pesticide and related chemicals have been found in the eggs, fat and tissues of the birds…. [The falcons] are not picking up the DDT directly, but get it by eating other birds which...

    Shutdown aside, Joshua trees live an odd life

    A year when vandals trashed a Joshua tree in a national park during a U.S. government shutdown is a good time to talk about what’s so unusual about these iconic plants.

    The trees’ chubby branches ending in rosettes of pointy green leaves add a touch of Dr. Seuss to the Mojave Desert in the U.S. Southwest. Its two species belong to the same family as agave and, believe it or not,...

    This rediscovered Bolivian frog species survived deadly chytrid fungus

    Save for one “lonely” survivor in captivity, the Sehuencas water frog hadn’t been seen in the wild since 2008. That’s when its numbers collapsed, primarily due to chytridiomycosis, a fungal disease that has devastated frog populations worldwide. Fearing the species might be extinct, some scientists spent 10 years searching the Bolivian mountain forests for the amphibians. Now, they’ve found a...

    Endangered northern bettongs aren’t picky truffle eaters

    A small endangered marsupial with a taste for truffles may be a linchpin in one kind of Australian forest — and the evidence is in the animal’s poop.

    Northern bettongs feast on truffles, the meaty, spore-producing parts of certain fungi. Plenty of animals eat a selection of these subterranean orbs from time to time. But analyses of the scat from northern bettongs (Bettongia tropica)...
