New research suggests that humpback whale populations in the Atlantic and Indian Oceans are picking up musical ideas from one another, and incorporating the new phrases and themes into their songs. According to the study, published November 28, 2018, in the peer-reviewed journal Royal Society Open Science, humpback whale populations in different Southern Hemisphere ocean basins (the South Atlantic and Indian Oceans) sing similar song types, but the amount of similarity differs across years.

Saplings from clones of the world's largest and longest-lived trees, felled for timber more than a century ago, could be key to fighting climate change.

In an ironic twist, the mammals also dine on carcasses of their main predator, the Canada lynx, a new study says.

The tidy rows of gleaming solar panels at Pine Gate Renewables facility in southwestern Oregon originally sat amid the squat grasses of a former cattle pasture. But in 2017 the company started sowing the 41-acre site with a colorful riot of native wildflowers. The shift was not merely aesthetic; similar projects at a growing number of solar farms around the country aim to help reverse the worrying declines in bees, butterflies and other key pollinating species observed in recent years.

Formally known as Achatinella apexfulva, the 14-year-old Hawaiian tree snail was the last of its kind on the planet.

The extravagant splendor of the animal kingdom can’t be explained by natural selection alone — so how did it come to be?

In the aftermath of California’s wildfires, rebuilding trails becomes a community effort and for some, a chance to heal and to help.

One of America’s native wild canines, the red wolf, has teetered on the brink of extinction for decades. And despite the efforts of a captive breeding program started in the 1970s, only about 40 such wolves are known to be still living in the wild today, all in North Carolina. But researchers at Princeton University have made a strange discovery that might spell good news for the future of the species: A population of wild dogs, isolated off the coast of Texas, that seem to carry red wolf genes, including remnants of DNA thought to be lost forever.

Thanks to the compounds used to protect precious flowers, antifungal resistance is here—and it could be just as dangerous to humans as antibiotic resistance.

Parasites that control the behavior of their hosts for their own benefit are a well-documented natural phenomenon, but the discovery of a previously unknown relationship between a parasitic wasp and a social spider is particularly upsetting.

It has eight arms, three hearts — and a plan. Scientists aren’t sure how the cephalopods got to be so intelligent.

There’s not much to be grateful for after the great Western Monarch Thanksgiving Count this year. The three-week volunteer effort in California dispatches scores of volunteers to hunt in their woods, backyards, and fields in search for the colorful migrating butterfly.

Photographer Mads Nordsvee describes the sighting as a "fairytale moment".

They live thousands of feet below the Earth’s surface. They eat hydrogen and exhale methane. And they may shape our world more profoundly than we can imagine.

Why trees grown in test tubes could be the answer to preserving the world's forests for the future.

In Venezuela, the red siskin (Spinus cucullatus), a vibrantly colored red-and-black finch, is inextricably linked with the country’s identity. It is present in poems, paintings, names of streets and sports teams and even graces the back of the 100,000 Bolivar bill, but it is rare in its natural habitat. To help reverse this, the Smithsonian and the Piedra de Cachimbo coffee farmers in northern Venezuela stepped in.

Plants are boring. They just sit there photosynthesizing while animals have all the fun. Right? Not so much. Take a look at the interactions between ants and plants—plants have evolved features specifically to make them enticing to ants, like juicy nectar for the insects to eat and hollow thorns for them to take shelter in. In exchange, plants use ants to spread their seeds and even act as bodyguards.

Destruction likely to be just the tip of the iceberg, campaigners warn

Researchers are just now beginning to understand what happens when one whale species attacks another

When do you need a broadsword, and when would you be better off with a dagger? That’s the question that faced artiodactyls, the group of mammals that includes deer, antelope, goats, giraffes, pigs, buffalo and cows, during their evolution. Many male artiodactyls fight over females using weaponized body parts such as horns and antlers. But pigs and several groups of deerlike animals have tusks instead, and a few species have both. Water deer have tusks so pronounced they are nicknamed “vampire deer.”

Containment measures meant to stop a rampant bacterium have been frequently delayed.

Climate change is altering America’s first national park so quickly that plants and animals may not be able to adapt.

Bulldozers are expected to soon plow through the protected habitat of the National Butterfly Center along the Rio Grande to clear the way for President Trump’s border wall, which got a green light from the Supreme Court this week. Hundreds of thousands of butterflies flit through the center’s 100-acre sanctuary. But 70 percent of the land will eventually be on the other side the wall, said Marianna Wright, the executive director. “We do not know...
