Ecology

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.

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

The underappreciated benefits of wild bees

Native pollinators are key to both ecology and agriculture, but have yet to get their due

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?  

Abandon the idea of ‘great green walls’

OPINION: The notion of planting miles of trees to hold back encroaching deserts is misguided and damaging; we should promote programs that secure livelihoods and respect dryland ecologies instead

Conservation paleobiology: Eyeing the past to restore today’s ecosystems

Researchers use historic remnants like antlers, shells, teeth and pollen to learn how natural communities once worked. The clues serve as guides for restoration.

Why one deforestation solution has yet to stop massive tree loss

OPINION: Zero-deforestation supply-chain commitments aren’t protecting tropical forests as much as hoped. But they might, if the same standards were applied to domestic and export markets.

Natural pest control: Plants enlist their enemies’ enemies

These stealthy survival tactics could teach us how to curb the widespread use of chemical pesticides in agriculture. But first, researchers must learn how seemingly helpless flora deploy this masterful strategy.

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.

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.

Not enough fish in the sea

The scientist who found a way to tally up global catches is an ocean advocate and a vocal critic of industrial fisheries. Now we have a treaty for the high seas — but does it go far enough?

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.

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?

City birds are changing their tune

Several species of urban-dwelling birds have modified their songs in response to human-generated noise
