The closure of a gate at a national wildlife refuge in Denver about a decade ago ensured protection for bison, bald eagles and other wildlife inside, but also created a physical and metaphorical barrier for people living in diverse communities just outside the fence.
Whether it involves nectar-sucking butterflies or blood-sucking mosquitoes, the ingestion of liquid food has long been known for many insects and other arthropods.
Winters on the Canadian prairies can be brutally cold, but researchers at Western University and Natural Resources Canada have found that even a freezing polar vortex poses little problem for the invasive emerald ash borer.
A new dinosaur which formed part of an array of 'unusual' creatures has been discovered in Argentina.
Minute fossils unearthed in preserved charcoal point to the existence of an entirely unknown group of plants that were among the first to move onto land.
The carnivorous Venus flytrap can be anesthetized with ether. Some surprising parallels to anesthesia in humans emerge.
Australia is losing its birds at an alarming rate—one in six species are now threatened with extinction, predominantly due to climate change, land clearing and worsening bushfires.
Satellite images could offer a new way to monitor for avalanche threats to remote mountain communities, according to Aberdeen scientists studying a deadly Himalayan avalanche.
This week a peer-reviewed study confirmed what many have suspected for years: major oil companies are not fully backing up their clean energy talk with action.
Chances are you’ve never heard of Eunice Foote, but she was the first person to document climate change. Five years before the man credited for discovering it.
The latest research into health-related risks associated with climate change has come in. Based on the contributions from more than 80 experts, the comprehensive study, entitled Health of Canadians in a Changing Climate:
Research prompts warnings humanity is ‘financing its own extinction’ through subsidies damaging to the climate and wildlife
A team of researchers affiliated with institutions in the U.S., Mexico and Australia has found evidence of humpback whales traveling thousands of miles to mate. In their paper published in the journal Biology Letters, they describe their findings and what it could mean for conservation efforts f ...
As they annoyingly buzz around a batch of bananas in our kitchens, fruit flies appear to have little in common with mammals. But as a model species for science, researchers are discovering increasing similarities between us and the miniscule fruit-loving insects.
This may sound counterintuitive, but reducing the number of animals in a population can help the remaining individuals to survive through the winter.
The environmental benefits of stranded whale and dolphin carcasses are being undermined by coastal regulations which require remains to be quickly disposed of, a new study has found.
Europe's Mediterranean countries produce a significant portion of the world's wines, olives, nuts and tomatoes. But research shows that the region's farms and orchards are the most susceptible in Europe to soil degradation and desertification.
Most commercial fertilizer travels a long way before it reaches rural farmers in Kenya. Transportation costs force many farmers to rely on cheap, synthetic fertilizers, which can lead to the acidification and degradation of their soil over time.
A comprehensive new map and report tracking whale migrations around the globe highlights where they go in the high seas and the cumulative impacts the animals face from industrial fishing, ship strikes, pollution, habitat loss and climate change.
In two sets of procedures between October 2021 and February 2022 the BioRescue consortium created two new northern white embryos, bringing the total to 14.
The universal language of music could serve as a gateway to communicate with dolphins and possibly open doors to learn more about the naturally curious creatures, according to researchers from The Australian National University (ANU).
California's massive fire seasons the past two years are part of a trend that scientists have traced back for more than four decades. The area consumed each year by fires has increased significantly over that period—particularly in the Sierra Nevada and northern parts of the state.
Immediate and rapid reductions in greenhouse gas emissions are needed to avoid the worst of climate change. The second REgional Carbon Cycle Assessment and Processes (RECCAP2) study is providing accurate scientific data on sources and sinks of the three main greenhouse gases for 2010-2019 for al ...
Over the past year alone, Indigenous communities in B.C. and throughout Canada have been severely drought, wildfires, floods and temperature changes related to climate change.
When most people think of flavonoids, natural compounds found in plants and other organisms, their nutritional benefits probably come to mind first. But these compounds may have another health benefit: Researchers from Japan have discovered that certain flavonoids inhibit development in mosquito ...
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 ...
Just before the closing scenes of the Cretaceous Period, India was a rogue subcontinent on a collision course with Asia. Before the two landmasses merged, however, India rafted over a "hot spot" within the Earth's crust, triggering one of the largest volcanic eruptions in Earth's history, which ...
America’s vast coastline is being assailed by rapidly encroaching oceans, with up to 1ft of sea level rise expected in the next 30 years – an increase that equals the total rise seen over the past century, a major US federal government report has found.
A new study by Tel Aviv University researchers found that in a marine environment, microplastics absorb and concentrate toxic organic substances and thus increase their toxicity by a factor of 10, which may lead to a severe impact on human health.
Clouds play a critical role in the global climate system. The unique Antarctic environment, with extremely low temperature, low moisture, and low aerosol concentration, makes cloud formation different from that in other regions, including the Arctic.
The astonishing force of the Tonga volcanic eruption shocked the world, but the fact that this underwater volcano actually erupted came as less of a surprise to geoscientists using satellite data to study changes in the temperature deep below Earth's surface.
Nighttime fires have become more intense and more frequent in recent decades, as hot, dry nights are more commonplace, according to a new study led by the Cooperative Institute for Research in Environmental Sciences' (CIRES) Earth Lab at the University of Colorado Boulder.
Politics and society largely dictate climate policy ambitions and therefore the trajectory of greenhouse gas emissions, yet climate change models and projections rarely include political and social drivers.
Two Clemson University engineers say their research is the most comprehensive analysis so far of what causes flash drought, a weather phenomenon that has been blamed for billions of dollars in crop damage and increased wildfire risk. The work is supported by the U.S. National Science Foundation.
Sea levels are rising, and that will bring profound flood risks to large parts of the Gulf and Atlantic coasts over the next three decades.
Poor and marginalized people in Wales are most likely to be exposed to the negative effects of climate change, a report has found.
When Charles Darwin first codified the theory of evolution by means of natural selection, he thought of it as a gradual process. "We see nothing of these slow changes in progress, until the hand of time has marked the long lapse of ages," he wrote in his seminal work, "On the Origin of Species."
A study based on a new varanid fossil species from China shows that the transition from the ancient Varaniformes to Varanus occurred in Asia and supports the Asian origin of Varanidae.
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.
Madagascar is the most important country for vanilla production—the fragrant ingredient that is a favorite flavor for ice cream, cakes and cookies. The vanilla orchid is cultivated in the tropical northeast of the island.
Cedarwood oil can be found in many consumer products—perfumes, soaps and deodorants among them. In addition to its pleasing scent, cedarwood oil also is prized for its insect-repelling and anti-fungal properties.
Decabromodiphenyl ethane (DBDPE) has increasingly been used as an alternative to decabrominated diphenyl ether (BDE209) in consumer products such as plastics, textiles, furniture, and electric/electronic devices.
An iconic winged beauty feared to be on the verge of extinction was spotted more around the West last year, including in Colorado.
Scientists analyzing one of the largest genomic datasets of plants have discovered how the first plants on Earth evolved the mechanisms used to control water and transpire on land hundreds of millions of years ago.

A team of researchers from Italy, the U.K. and South Africa has found that over the past decade, the only two flowering plants in Antarctica have been growing more rapidly.
As a ubiquitous energy source and environmental signal, light affects the lifestyle of organisms living in the photiczone.
A common refrain among biologists holds that the majority of Earth's plant and animal species remain undiscovered. While many of those species inhabit narrow or hard-to-reach ranges, others may in fact be hiding right under our noses.
Until recently, experts considered it unlikely that the honeybee had survived as a wild animal in Europe. In a current study, biologists Benjamin Rutschmann and Patrick Kohl from Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, show that wild honeybees still exist in the region ...
A CABI-led study has conducted a comprehensive survey of nearly 200 potentially harmful alien plant species that could have a detrimental impact upon agriculture, forestry and biodiversity in Ghana once they enter the country.
