This poor ancient sea cow was first killed by a crocodile and then eaten by a shark some 20 million years ago

A sea cow's fossil offers a rare glimpse into Miocene-era predation

Trees in the Amazon are "running" uphill to escape from climate change

Trees are searching for colder temperatures, with far-reaching consequences for the entire ecosystem.

This coastal ecosystem was degraded and damaged. Then, the otters came in

Otters remarkably managed to fix this ecosystem — even down to its geology.

Tiny ants are sending ripples through African ecosystems, changing how lions hunt

The tiny ant is more powerful than you'd think.

This ecosystem shows what Earth was like billions of years ago

Hidden in one of the driest environments on the planet are lagoons teeming with life

California is losing its trees -- perhaps permanently -- as climate change is shifting its ecosystems

Trees are burning and grasslands are taking their place.

Almost half of the world is now "degraded"

We're leaving no stone unturned.

Archaea: the invisible powerhouses of the planet

Archaea are probably the most successful beings on Earth. They've been around for billions of years and can survive almost anywhere.

Different cities have their own microbial fingerprint, a global study reports

"If you gave me your shoe, I could tell you with about 90% accuracy the city you came from," the authors boast.

The world's largest ecosystems could collapse in decades -- much faster than previously thought

Scientists are concerned about the irreversible damage done to global ecosystems.

Ecosystems with varied plant species are lusher, more efficient

Greater plant diversity benefits everyone in the ecosystem, a new study reports. Higher levels of plant diversity allow ecosystems to utilize more energy and more efficiently, new research found. Ecosystems with 60 or more plant species contained twice the amount of living biomass, on average, than ecosystems built on plant monocultures. This is the first […]

Tropical forests and coral reefs are buckling under interacting threats

When it rains, it pours.

What is biodiversity

Diversity, 100% biological.

Climate change and ozone layer holes form feedback loop, reports international panel

"Greenhouse gas emissions trap more heat in the lower atmosphere which leads to a cooling of the upper atmosphere. Those colder temperatures in the upper atmosphere are slowing the recovery of the ozone layer."

What is soil? Here's the inside scoop

The Earth's great recycle bin.

Arctic plants are getting taller due to climate change -- which could fuel more climate change

Well, this is an unusual problem to have.

Climate change will become the leading cause of vertebrate-species loss by 2070

Things are heating up.

Limiting global warming to 1.5 degree C would save most global species, new study concludes

... but if we keep on with the "business as usual" approach, things will be much worse.

Scientists successfully transplant coral into the devastated Great Barrier Reef

This successful first trial might one day save the reef.

Juice company dumped orange peels in Costa Rican national park in the 90s -- it revived the forest

Orange is the new forest.

Pristine mountain habitats are also not safe from climate change

Incoming climate change will have a drastic effect on pristine mountain habitats, a new study has found.

Humanity is driving thousands of species extinct, but there's a flip side -- we also create new species

Humans -- tyrants of creators? Two researchers explored this duality by studying both extinct species and those who had evolved as a direct influence of man.

Are cephalopods taking over the oceans?

Human activity has been wreaking havoc on ocean life. One group however seems to thrive where others struggle to survive: new evidence shows that cephalopods' numbers have significantly increased over the last six decades.

Why don't they just eat all of them - predator-prey study reveals new law governing ecosystems

The results of a new study offer insight into the workings of predator-prey mechanisms, more specifically how the number of herbivores and other animals that are preyed upon affect the number of carnivores.

Ecosystems still feel the pain of ancient extinctions

The more researchers study ecosystems, the more we learn that an ecosystem behaves, in many ways, just like a living organism: thousands of years after human hunters wiped out big land animals like giant ground sloths, the ecosystems they lived in are still suffering from the effects, much like a body suffers from past trauma. […]

New study estimates 1 million marine species - one third still unknown

The world’s oceans are teeming with life, a new census estimating almost 1 million species out there; but marine life is declining, with the main causes being overfishing, ocean acidification and coastal damage. Avoiding a crisis The new numbers are just estimates, but they are much lower than previous studies, which put the number of […]

Earth took 10 million years to recover from biggest extinction

Some 250 million years ago, life on Earth passed through its toughest time so far, as 96% of all marine species and over three quarters of land vertebrates went extinct. According to British researchers, the mass extinction was so severe that it took life 10 million years to recover. With less than 10 percent of […]

Seagrass on ocean coasts can store twice as much carbon as tropical rainforests, yet face destruction

A new research from a team of international marine geoscientists has found that seagrass meadows, found in coastal regions, can store up to twice as much carbon as temperate or tropical forests. The scientists involved in the study, thus, believe that seagrasses can potentially become a viable solution to climate change, if scaled and preserved […]

Antarctic plant ecosystem threatened by 'alien' seeds

Antarctica is home to one of harshest environments in the world, but exactly because of this it exhibit a unique set of fauna to the world. As the local arctic climate warms, however, and an increasing number of tourists and scientists are bringing in thousands of seeds, once pristine ecosystems are now at risk. Seeds […]

Ocean life threatened by mass extinction

Climate change and over-fishing are held responsible for the swift collapse of coral reefs and the propagation of mass extinction among marine life. According to the International Programme on the State of the Ocean (IPSO), which presented the study this Tuesday to the U.N., the Earth is faced with its biggest spate of mass extinctions […]

Fool's gold is ocean's fertilizer

Bacteria and small plants at the bottom of the ocean require significant quantities of iron to survive and grow, just like us humans do. But their situation is extremely different, and they can’t just opt for an iron rich diet. So where does their iron come from ?   Pyrite, or fool’s gold (as it […]

Underwater... lakes !

Boy I’ve gotta tell you, my jaw really dropped when I heard this one. There are actual lakes, on the bottom of oceans, especially in the Gulf of Mexico region; they’ve got their own shores and all. The brine water of these lakes actually hosts unique wildlife, creating an absolutely amazing environment. The fact that […]

Stunning variety of sea life found in Antarctica

The British Antarctic Survey (BAS) published some quite awesome pictures showing that Antarctica isn’t the lifeless frozen wasteland most people believe it to be; ice fish, octopus, sea pigs, giant sea spiders, rare rays and gorgeous basket stars all thrive in the extreme temperatures in Antarctica’s waters. Well, thrive is perhaps a too strong word, […]
