An amphibious rescue mission

On the edge of extinction, rare frogs and toads need more than a little love to reproduce. High-tech help, from IVF to hormone therapy, may save them.

The creative way to pay for wildlife recovery

OPINION: ‘Pragmatic rewilding’ restores damaged ecosystems and harnesses private money, with benefits for all

How humans shift fish evolution | Things to Know

VIDEO: By targeting larger individuals, intense fishing may lead to a fishery dominated by the small

The accidental tree killers

Epidemics of forest-felling diseases are on the rise thanks to globetrotting pathogens that slip through even the best defenses. To prevent further losses, scientists are turning to high-tech surveillance and detection, even canine noses.

As coral die, protected areas aren’t enough

COMIC: The reef-builders face larger threats, scientists say. Chief among these is warming seas.

The human hand in fish evolution

Fishery practices that go for the big ones may be counterproductive when mostly the small survive

A new history for the tropical forests of the Americas

Fossilized leaves and pollen are revealing the evolutionary past of New World tropical forests. The findings are helping to reshape predictions of what might happen to these ecosystems as the climate changes.

How truffles took root around the world

For centuries, the wild delicacy grew only in Europe. But improved cultivation techniques have enabled the pricey, odorous fungus to be farmed in new landscapes.

A shocking number of birds are in trouble

Rich data on the global state of our feathered friends presents plenty of bad news — but also some bright spots. Researchers know better than ever how to help endangered birds, and there are notable bird conservation successes.

Eyes on the deep

Decades of exploring the seafloor have helped oceanographer Samantha Joye tackle marine issues — from the underwater movement of oil from Deepwater Horizon to the biology of remote microbial communities

Betting on bats for genetic treasures

Bat genomes are full of clever tricks that are treats for biology and medical science — it’s why scientists want to sequence them all

A salamander’s dangerous liaisons

The giant genomes of these struggling amphibians tell a story of outsider invasions, assault by disease and cross-species sex. A geneticist explains.

Photograph of Kevin Lafferty climbing onto a small boat from the waters off Anacapa Island near Ventura, California, after spearing fish in March 2018. He’s advising a UC Santa Barbara PhD student on research to determine if reef fish inside protected marine reserves have more or fewer parasites than the depleted fish populations outside the reserve. It’s to test a pattern that has emerged in other studies: that parasites thrive with richness and abundance of marine life.

In praise of parasites

They worm into snails and infect the brains of fish. They’ve also found their way into Kevin Lafferty’s heart. He sees them as beautiful examples of sophisticated evolution, and as keys to ecosystem balance.

Marine wildlife is starting to suffocate

Global warming and agricultural runoff have driven the loss of oxygen in oceans around the world, with looming ecological consequences.

Scientists can’t agree about Chernobyl’s impact on wildlife

Is Chernobyl a radioactive wasteland reeling from chronic radiation, or a post-nuclear paradise with thriving populations of animals and other life forms? Studies don’t always agree about levels of mutations and other ill effects.
