Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.

Nearly 400 exceptionally well-preserved fossils dating back 470 million years have been discovered in the south of France by two amateur paleontologists. The discovery provides unprecedented information on the polar ecosystems of the Ordovician period.

Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.

Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.

The rivers of Australia, which once flowed across its now dry interior, used to host a range of bizarre animals -- including a sleek predatory lobe-finned fish with large fangs and bony scales. The newly described fossil fish discovered in remote fossil fields west of Alice Springs has been named Harajicadectes zhumini by palaeontologists.

Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.

The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?

Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new article focused on the spatial patterns found in drylands offers important empirical evidence validating the models.

Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.

In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

Scientists developed a new method to map exactly how a fungus works with leafcutter ants in a complex microbial community to degrade plant material at the molecular level. The team's insights are important for biofuels development.

Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.

We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.

Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.
