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 human hand in fish evolution

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

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.

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.

The teeming life of dead trees

Rotting logs turn out to be vital to forest biodiversity and recycling organic matter

Reviving a famously polluted California lake

Clear Lake, the state’s largest freshwater body of water, is fouled each year by algal blooms, one of many assaults endured by the battered ecosystem. Can a multipronged plan help it recover?

The fight against an invasive fish in California’s Clear Lake

VIDEO: Can removing carp help the lake’s native fish and keep toxic algal blooms in check?  

Leaning into Indigenous knowledge on climate change

Native peoples attuned to the natural world have long collected detailed environmental information. Now scientists are cataloging these observations and learning how they’re affecting Indigenous communities globally.

To help birds and insects, cultivate native gardens

Entomologist Doug Tallamy explains how filling our yards with local plants can provide our feathered friends with a caterpillar buffet

How wind turbines could coexist peacefully with bats and birds

As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.

Does it work to pay people not to cut the forest?

Evidence that the approach helps to save trees, preserve ecosystems and reduce carbon emissions is often hard to come by. But it can succeed if it’s done right, says an economist.

Invasive species are transforming the Everglades

From Burmese pythons and Asian swamp eels to Old World climbing ferns, South Florida hosts hordes of non-native animals and plants. What can be done about the ecological havoc they are wreaking?

How farmers can help rescue water-loving birds

Cranes, sandpipers, ducks, geese and many other waterbirds have lost essential rest stops along their seasonal migration routes. Bird-friendly agriculture can assist in filling the gaps.

Hunting sky islands for genetic clues to climate resilience

OPINION: Isolated mountaintops are hotbeds of evolutionary adaptation and great places to study how climate change affects ecosystems

Forests are under attack from invasive species

OPINION: International commerce and travel bring ecological destruction to the world’s most cherished natural places. We need to do more to stop the assault.

Indigenous languages are founts of environmental knowledge

Peoples who live close to nature have a rich lore of plants, animals and landscapes embedded in their mother tongues — which may hold vital clues to protecting biodiversity

Our oceans’ future: Hot and troubled

OPINION: Ocean warming, acidification and deoxygenation due to climate change — as well as pollution and development — threaten our global waters, but disaster is far from inevitable

Losing the connection between the Andes and the Amazon: A price of peace in Colombia

The South American country, where the biodiversity of the Andes meets that of the Amazon, is losing the great natural wealth of some 1,500 square kilometers of forest each year, mainly in areas formerly under guerrilla control

The case for ocean optimism

With the health of the ocean under threat, a rallying cry for marine conservation goes global. Here are some of the good-news stories.

Moving trees north to save the forests

As the world warms, trees in forests such as those in Minnesota will no longer be adapted to their local climates. That’s where assisted migration comes in.
