Living World

Dealing with rats, and their health, in America’s ‘rattiest’ city

OPINION: A study in Chicago found that rodents surviving poisoning are more likely to carry disease. Good pest control needs to take such things into account.

Nature, nurture and randomness

OPINION: More than genes and upbringing determine animal personalities: There’s a good dose of chance in the mix, too.

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

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.

Get out in your yard and count bugs

OPINION: How worried should we be about insect declines? Community science is vital for gathering information about arthropods.

Mysteries of the poisonous amphibians

Many brightly colored frogs and salamanders have enough toxins in their skin to kill multiple people. How do they survive their own noxious weapons?

We need to stop bugs at the border

OPINION: Trade and travel come with a shared responsibility for biosecurity

Zoos need to change

OPINION: To justify their existence, they must make conservation their top priority

As glaciers retreat, new streams for salmon

Ecologist Sandy Milner has traveled to Alaska for decades to study the development of streams flowing from melting glaciers. He’s seen insects move in, alders and willows spring up, and spawning fish arrive in thousands.

Animal personalities can trip up science, but there’s a solution

Individual behavior patterns may skew studies. A new approach called ‘STRANGE’ could help, by taking into account the habits, tendencies and life experiences of the creatures under scrutiny.

How animals follow their nose

It’s not easy to find the source of a swirling scent plume. Scientists are using experiments and simulations to uncover the varied strategies that animals employ.

Controlled burns won’t save all of California from wildfire

There are two types of wildfire in the state, and they’re on the rise for different reasons. Each needs a distinct management approach, a researcher says.

How lunar cycles guide the spawning of corals, worms and more

Many sea creatures release eggs and sperm into the water on just the right nights of the month. Researchers are starting to understand the biological rhythms that sync them to phases of the moon.

Could getting rid of old cells turn back the clock on aging?

Researchers are investigating medicines that selectively kill decrepit cells to promote healthy aging — but more work is needed before declaring them a fountain of youth

How the brain calculates a quick escape

Whether fly or human, fleeing from danger is key to staying alive. Scientists are beginning to unravel the complex circuitry behind the split-second decision to beat a hasty retreat.

Mistletoes in a warming world

Can the famous parasitic plants help animals to survive climate change, or will they be killed off by extreme weather?

Edith’s checkerspot butterfly: Checkered past, uncertain future

How do animal populations respond to climate change? After studying the same butterfly and its habitats for decades, two biologists explain that it’s complicated — but endlessly intriguing.

As the Arctic warms, beavers move in

Scientists are just beginning to study the impacts of beaver dams on the tundra

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.

Blessed are the (tiny) cheesemakers

Cheese is not just a tasty snack — it’s an ecosystem. And the fungi and bacteria within that ecosystem play a big part in shaping the flavor and texture of the final product.
