Will modern coral reefs go extinct? The answer is uncertain, but some of their ancient counterparts managed to dodge a bullet—for a while, at least.

Drone footage captured by researchers in Oregon State University's Marine Mammal Institute is offering new insight into the acrobatics undertaken by gray whales foraging in the waters off the coast of Oregon.

In a study published in Proceedings of the Royal Society B, researchers at the UH Hawaiʻi Institute of Marine Biology (HIMB) Toonen- Bowen "ToBo" Lab have identified scenarios under which eight of the most common species of coral found in Hawaiʻi can adapt to and survive ocean warming and acidification.

If you'd stopped monitoring the Adriatic Sea's marine life in the mid-20th century, the outlook would have been promising. Snails and the clams they hunt for food increased in abundance for several decades during the late 1800s and early 1900s, evidence of a vibrant and healthy ecosystem.

The ocean's twilight zone is deep, dark, and—according to new research—iron deficient. No sunlight reaches this region 200 to 1,000 meters below the sea surface, where levels of iron, a key micronutrient, are so low that the growth of bacteria is restricted. To compensate, these bacteria produce molecules called siderophores, which help the bacteria scavenge trace amounts of iron from the surrounding seawater.

A research team from Freie Universität Berlin has discovered that soil properties are severely impacted when subjected to a large number of different environmental stressors. The study is published in Nature Communications.

An international team of scientists has made a discovery that could reshape our understanding of how global biodiversity evolved. By reconstructing the evolution of species over the past 45 million years, researchers found that the geographic origins of many plants, insects and mammals are more closely linked than previously thought.

When thinking of animal camouflage, we typically imagine creatures remaining still, blending seamlessly into their surroundings. But remaining motionless isn't always practical, and many animals are highly mobile, constantly moving through their environment to graze their food.

In an innovative paper published today in the journal Plants, People, Planet, scientists from the Royal Botanic Gardens, Kew, Huarango Nature and paramotorists from Forest Air, highlight the exciting potential of paramotoring as a means of aiding research and conservation efforts in some of the most fragile and challenging parts of the globe.

Electric power companies dedicate significant resources to clearing overgrown plants and debris from the area surrounding power lines. These areas are known as electric rights-of-way, and anything that obstructs access to them can threaten power outages, hinder public safety and make it harder for utility crews to perform necessary maintenance and repairs.

Fruit bats generate more diverse antibodies than mice, but overall have a weaker antibody response, according to a new study published September 24 in the open-access journal PLOS Biology by Dan Crowley from Cornell University and colleagues.

Until a few years ago, the butterfly known as the southern small white could barely be found north of the Alps. That was before a Europe-wide invasion that brought a huge increase in the insect's distribution—at the same time as a rapid decrease in genetic diversity within the species.

The Eiffinger's tree frog (Kurixalus eiffingeri), found on Ishigaki and Iriomote islands in Japan, has a unique biological adaptation: its tadpoles do not defecate during their early developmental stages. This finding by researchers at Nagoya University in Japan contributes to our understanding of how these small frogs survive in the tiny bodies of water where they spawn. The findings were published in the journal...

Coral reefs will continue to experience severe heat stress as rising temperatures cause the oceans to become unbearably hot—but a new study shows that altering their feeding habits could allow local populations to avoid total extinction.

Instead of nurturing their sick young, ant queens eat their infected offspring at the first sign of illness then "recycle" them into energy to produce new eggs, a new study led by the University of Oxford has shown. The findings have been published in Current Biology.

In a new study, researchers at the University of Illinois Urbana-Champaign tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors together, the scientists found that good nutrition enhances honey bee resilience against the other threats.

A new species of flatworm has been discovered and has already invaded several states in the southern United States. The particularity of the new species is that it looks a lot like Obama nungara, a species that has invaded much of Europe. The new species has been named Amaga pseudobama in reference to this resemblance.
