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.

Collective behavior: How animals work together

Studies of birds, fish and ants reveal the hidden ways groups coordinate movement, which might influence engineers designing drone armadas and efficient information flow

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.

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.

The cultural lives of birds

VIDEO: Culture was once thought to be uniquely human, but scientists are finding evidence that many birds are also cultural creatures. What does avian culture look like? And why does it matter?

There goes the night

Artificial lights spell darker times for much of the planet’s wildlife — but it doesn’t have to be that way

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.

Nature, nurture and randomness

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

City birds are changing their tune

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

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.

In the Great Pacific Garbage Patch, new marine ecosystems are flourishing

Sea life, stuck to plastic bottles and other human trash, has journeyed far from coastal habitats — and may threaten local species

Frogs kick back against lethal fungus

Scientists are seeing signs of resistance to the infections that have been wiping out the world’s amphibian populations — and developing strategies to aid in the fight Down Under

One fish, two fish, 3,000 fish ...

Groups of cichlid fishes in East Africa radiated into thousands of species within dazzlingly short periods of time. How did they do it?

A lifetime of love for the charismatic narwhal

An independent scientist working with the Inuit has unraveled many mysteries of the one-tusked ‘unicorn of the sea’

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

They swim and they spin: Meet the aquatic spiders

Some make nests inside seashells, others tote bubbles of air on their backs. The spiders that went back to water evolved lots of slick survival strategies.
