Published Roadside hedges can reduce harmful ultrafine particle pollution around schools



A new study confirms that planting hedges between roadsides and school playgrounds can dramatically reduce children's exposure to traffic-related particle pollution.
Published Freshwater connectivity can transport environmental DNA through the landscape


A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published New rivers in the North? Scientists identify how the dissection of Arctic landscapes is changing with accelerating climate change



New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years.
Published Climate change is reducing global river water quality



A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.
Published Fewer but more intense tropical storms predicted over the Ganges and Mekong



Climate experts project a decline in the frequency of future tropical storms but an increase in their strength across the Ganges and Mekong basins allowing for better future planning.
Published Invasive red fire ants spreading in Europe



One of the most invasive species in the world is Solenopsis invicta, a red fire ant species with a painful sting. Native to South America, the ant has established itself across the globe. A group of ant experts confirm that the species has made its way to Sicily -- the ant's first official sighting in Europe. The ants could soon spread all over the continent, the researchers warn, which could cause major environmental, health, and economic problems in Italy and beyond.
Published Helicopter-based observations uncover warm ocean water flows toward Totten Ice Shelf in Southeast Antarctica



An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.
Published Scientific ocean drilling discovers dynamic carbon cycling in the ultra-deep-water Japan Trench



Hadal trenches, with their deepest locations situated in the so-called hadal zone, the deepest parts of the ocean in water depth >6km, are the least-explored environment on Earth, linking the Earth's surface and its deeper interior. An international team conducting deep-subsurface sampling in a hadal trench at high spatial resolution has revealed exciting insights on the carbon cycling in the trench sediment.
Published Researchers charting a sustainable course in oceanic carbon capture



As researchers around the world race against time to develop new strategies and technologies to fight climate change, a team of scientists is exploring one possible way to directly reduce the amount of carbon dioxide in the environment: Negative emissions technologies (NETs).
Published Study reveals human destruction of global floodplains



A hydrologist's study provides a global estimate of human destruction of natural floodplains. The study can help guide future development in a way that can restore and conserve vital floodplain habitats that are critical to wildlife, water quality and reducing flood risk for people.
Published Beaver activity in the Arctic increases emission of methane greenhouse gas



The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.
Published Invasive alien species play key role in 60% of global plant and animal extinctions


A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published Bursting air bubbles may play a key role in how glacier ice melts



New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.
Published Ag tech can cut billions of tons of greenhouse gas emissions



As the Earth's human population grows, greenhouse gas emissions from the world's food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions -- reducing more greenhouse gas than food systems add.
Published Fossil spines reveal deep sea's past



Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
Published Balancing biodiversity, climate change, food for a trifecta


Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.
Published Invasive species are animals, too: Considering a humane approach


Invasive alien species are animals that may pose a threat to biodiversity, but it's time to deal with that threat in a more ethical way.
Published Large herbivores keep invasive plants at bay


Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
Published Farms that create habitat key to food security and biodiversity


Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
Published Blowing snow contributes to Arctic warming



Atmospheric scientists have discovered abundant fine sea salt aerosol production from wind-blown snow in the central Arctic, increasing seasonal surface warming.
