A new way of looking at marine evolution over the past 540 million years has shown that levels of biodiversity in our oceans have remained fairly constant, rather than increasing continuously over the last 200 million years, as scientists previously thought.
At first, the noise pulsing from the drooping elm tree boughs seemed to be coming from the power lines erected nearby. Like a surging electrical current, the sound fizzed to a crescendo on the ears before receding slightly, only to build up again to a loud, vibrating whirr.
Scientists are clear: the number of plant and animal species on Earth is declining. The climate crisis, habitat loss, pollution and the illegal wildlife trade are all pushing species toward extinction. Researchers especially worry that losing too much biodiversity could push the earth past a tip ...
Researchers exploring Antarctica’s seabed have discovered a thriving, unprecedented colony of icefish “about a third of the size of London”.
A focus on valuing nature through the lens of the market has contributed to the global biodiversity crisis, according to a recent report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
Love them or hate them, recent reports of an “insect apocalypse” sounded alarm bells around the world as conservationists warned of dire repercussions for people and ecosystems. But a wide-scoping meta-analysis of 166 long-term surveys across 1676 global sites shows the decline has considerable ...
Pete Knapp, 36, who lives in London, has visited North Korea, travelled overland from Kenya to Cape Town, motorcycled through Japan and Cambodia and trekked by horse through China. Until a few years ago, “I felt invincible,” he says. He had never experienced anxiety, or worried about the climate ...
Dig a teaspoon into your nearest clump of soil, and what you’ll emerge with will contain more microorganisms than there are people on Earth. We know this from lab studies that analyse samples of earth scooped from the microbial wild to determine which forms of microscopic life exist in the world ...
Wealthy people have disproportionately large carbon footprints and the percentage of the world’s emissions they are responsible for is growing, a study has found.
Scientists have announced a plan to map the genomes of at least 100 bee species, representing each of the major bee taxonomic groups in the U.S., to help them determine which bees are more vulnerable to climate change and pesticides.
There’s a tree-planting frenzy everywhere you look. In August 2019, the state of Uttar Pradesh in northern India announced that more than a million Indians had planted 220 million trees on a single day. A month earlier, Ethiopia had made a similar declaration: more than 350 million trees had bee ...
European green crabs feast on shellfish, destroy marsh habitats by burrowing in the mud and obliterate valuable seagrass beds. The invasive species also reproduces quickly, making it a nightmare for wildlife managers seeking to control its spread in Washington's marine waters.
Amazon forests are increasingly becoming fragmented by deforestation and fire. A new study published in Nature Communications and led by researchers in the University of Helsinki, in cooperation with scientists across the globe, uses a novel approach to quantify the impacts of fragmentation on p ...

Zoos and aquariums could improve the lives of a wider range of their animals, new research suggests. The use of "environmental enrichment" (giving animals stimulating environments) has become increasingly common in zoos and aquariums in recent years.
Zebra mbuna (a species of cichlid fish) and stingrays can add and subtract one from the numbers one to five, according to a study published in Scientific Reports.
A trio of researchers at the University of California has found that zebra finches are able to remember up to 42 bird voices based only on their vocalizations.
New research shows changes in tides and hurricane activity played a part in upending the Maya civilization centuries ago. Changes to the water table throughout the Yucatan Peninsula impacted the Maya and now offer lessons on the effects of present-day climate change, researchers say.
A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They've calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you're planning to take is worth destroying polar bear habitat.
As negotiations before the 15th Conference of the Parties to the Convention on Biological Diversity (COP-15) take place, international research has quantified the impact of human consumption on species extinction risk.
Over the past few decades, pollinators have been in decline worldwide, which is concerning because 70% of crops used for human food depend on pollinators. Turfgrasses—used for most residential lawns—often take some of the blame for pollinator decline as they are known to be wind-pollinated and w ...
The past few weeks have been hectic. Almost every week we had a party at home. Usually, Diwali celebrations continue for a month. Families invite other families for lavish meals, show off their beautiful saris, and kids go to sleep very late—I mean VERY late.
Young people are often seen as having a bleak worldview, plugged uncritically into social media and anxious about the climate crisis, among other pressing issues.
Mating changes female behavior across a wide range of animals, with these changes induced by components of the male ejaculate, such as sperm and seminal fluid proteins. However, males can vary significantly in their ejaculates, due to factors such as age, mating history, or feeding status. This ...
A team of researchers from Leiden University, University College London and the University of Amsterdam, has found that human infants laugh in ways that are more like chimpanzees than adult humans. In their paper published in the journal Biology Letters, the group describes their study.
Jack Tseng loves bone-crunching animals—hyenas are his favorite—so when paleontologist Joseph Peterson discovered fossilized dinosaur bones that had teeth marks from a juvenile Tyrannosaurus rex, Tseng decided to try to replicate the bite marks and measure how hard those kids could actually chom ...
A common belief in nature conservation is that people need to "know nature" in order to care about it. However, new research has found that farmers in the Brazilian Amazon can develop strong connections with nature despite having little knowledge of local biodiversity—in this case local bird spe ...
For more than a century, Yosemite National Park was viewed as a refuge where nature prevails unmolested by man-made forces amid picturesque vistas of granite cliffs, waterfalls and giant sequoias.
An individual human can maintain stable social relationships with about 150 people. This is the proposition known as "Dunbar's number"—that the architecture of the human brain sets an upper limit on our social lives. A new study from Stockholm University indicates that a cognitive limit on human ...
A trio of researchers from the University of Pisa has found that lions, like many other animals, engage in contagious yawning. In their paper published in the journal Animal Behavior, Grazia Casetta, Andrea Paolo Nolfo and Elisabetta Palagi describe their study of lions living in the wild in Afr ...
Yale researchers have joined the robust conversation regarding the Australian bushfires — a growing set of blazes that have drawn international statements ranging from climate activists lamenting koala deaths on Twitter to Russell Crowe appealing to the Golden Globes audience for change.
Less than a decade after unveiling the “Map of Life,” a global database that marks the distribution of known species across the planet, Yale researchers have launched an even more ambitious and perhaps important project — creating a map of where life has yet to be discovered according to Yale Un ...
As part of their biannual climate change perception reports, researchers from Yale University have identified six target audiences in the United States with unique responses to climate change.
Less than a decade after unveiling the “Map of Life,” a global database that marks the distribution of known species across the planet, Yale researchers have launched an ambitious and perhaps even more important project — creating a map of where life has yet to be discovered.
Little known is the fact that Chinese scientists have participated in joint research and biodiversity protection in the Amazon since 2008, contributing their wisdom to the world's largest tropical rainforest.
It's not just on land where heat waves occur; they can also happen underwater. New research in Frontiers in Marine Science uncovers recent and future trends in marine heat waves within the largest estuary in the nation, with catastrophic consequences for marine creatures and the coastal economy ...
Nagoya University researchers and colleagues have revealed the nerve circuitry regulating the response of a tiny soil worm to changing temperatures. The findings, published in the journal Proceedings of the National Academy of Sciences, help clarify one way the nervous system translates external ...
Historical photographs are increasingly used by conservation scientists to assess how places have changed over time, and the degree of human and environmental impact. Such is the case with black and white pahotographs taken in 1917 of the lush reefs, shore and villages surrounding Pago Pago Harb ...
Big banking is saying little on how they will combat climate change through their financing, shows a new study which finds minimal, clear commitments to aid financing away from fossil fuels.
An international team led by researchers at the Centre for Palaeogenetics in Stockholm has sequenced DNA recovered from mammoth remains that are up to 1.2 million years old. The analyses show that the Columbian mammoth that inhabited North America during the last ice age was a hybrid between the ...
The Southeast Asian box turtle is the most heavily trafficked turtle in the world – captured and sold to China for food and medicine and for the pet trade in the United States, Japan and Europe. But little was known about its ecology until a University of Rhode Island herpetologist spent six mon ...
A huge iceberg, the world's largest, has broken off from an ice shelf in Antarctica and is floating through the Weddell Sea, the European Space Agency said.
