How nitrogen has been underestimated in lake ecosystems
An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. This results in increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish deaths. Until now, controls in lake management have focu.....»»
Scientists use "leaf glow" to understand changing climate
New University of Minnesota research suggests "leaf glow" provides vital information on vegetation dynamics in Arctic and boreal ecosystems like Minnesota's forests and wetlands, which are among the fastest warming in the world. Using remote sensing.....»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Scientists map soil RNA to fungal genomes to understand forest ecosystems
If a tree falls in the forest—whether or not anyone registers the sound—one thing is for sure: there are lots of fungi around. Within a forest's soil, hundreds of species decompose debris, mobilize nutrients from that decay, and deliver those nut.....»»
Some cannabis rolling papers may contain unhealthy levels of heavy metals
A team of chemists at Lake Superior State University, working with colleagues from Wayne State University, both in Michigan, and two representatives from JEOL U.S., a lab equipment maker, has found that some cannabis rolling papers contain high level.....»»
Laser-treated cork absorbs oil for carbon-neutral ocean cleanup
Oil spills are deadly disasters for ocean ecosystems. They can have lasting impacts on fish and marine mammals for decades and wreak havoc on coastal forests, coral reefs, and the surrounding land. Chemical dispersants are often used to break down oi.....»»
Mangrove blue carbon at higher risk of microplastic pollution
Earth's oceans and coastal ecosystems are a major sink for carbon storage, known as blue carbon. Sequestration of carbon is vitally important in the fight against climate change as it 'locks away' this molecule, alleviating pressure on greenhouse gas.....»»
Io: New image of a lake of fire, signs of permanent volcanism
Juno captures images of Io's violence as study says it has always been that way. Enlarge (credit: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt/Thomas Thomopoulos) Ever since the Voyager mission sent home images of Jupite.....»»
Respiratory stress response that stunts temperate fish also affects coral reef fish
Coral reef fish, like the fish in other marine and freshwater ecosystems, are likely to reach smaller maximum sizes and start reproducing earlier with smaller and fewer eggs as climate change continues to warm up the ocean......»»
NASA"s Juno gives aerial views of mountain and lava lake on Io
Scientists on NASA's Juno mission to Jupiter have transformed data collected during two recent flybys of Io into animations that highlight two of the Jovian moon's most dramatic features: a mountain and an almost glass-smooth lake of cooling lava. Ot.....»»
Polystyrene microplastics shown to enhance invasion of exotic submerged macrophytes
Submerged macrophyte invasions and microplastic pollution are major challenges in the context of global change and pose a serious threat to aquatic environments. The presence of microplastics in aquatic ecosystems alters plant function, sediment micr.....»»
Invasive species sound off about impending ecosystem changes
Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring?.....»»
Rewilding amphibians: Protecting endangered species to restore ecosystems
In a recent paper published in Biological Conservation, iDiv researchers suggest that given amphibians' ability to act as "canaries in the coal mine" for aquatic environments, they should be reintroduced or rewilded. Rewilding would not only help pro.....»»
Migratory birds are on the move and nature-friendly farms can help them on their way
Every spring, hundreds of thousands of birds leave their winter habitat on Poyang, the largest freshwater lake in China, and fly north over the most densely populated region on Earth to reach their breeding grounds in Siberia. As with any long-distan.....»»
Light pollution affects coastal ecosystems, too—this underwater "canary" is warning of the impacts
In the early 20th century, canaries were used as early warning systems in coal mines to alert miners to rising levels of carbon monoxide......»»
Yellowstone Lake ice cover unchanged despite warming climate
The length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, despite warming temperatures in the region, according to new research led by University of Wyoming scientists......»»
Study finds patterns of crop-specific fertilizer-nitrogen losses, opportunities for sustainable mitigation
Nitrogen fertilizers play an essential role in ensuring global food security. However, the applied fertilizer-nitrogen, particularly that exceeding crop demand and soil N retention capacity, can potentially escape into the environment and lead to a v.....»»
Researchers shine light on rapid changes in Arctic and boreal ecosystems
Arctic and boreal latitudes are warming faster than any other region on Earth. In three new studies, Earth system scientists at the University of California, Irvine report how the ecosystems in these regions are changing......»»
SWOT satellite helps gauge the depth of Death Valley"s temporary lake
California's Death Valley, the driest place in North America, has hosted an ephemeral lake since late 2023. A NASA-led analysis recently calculated water depths in the temporary lake over several weeks in February and March 2024, demonstrating the ca.....»»
Northern permafrost region emits more greenhouse gases than it captures, study finds
Permafrost underlies about 14 million square kilometers of land in and around the Arctic. The top 3 meters contain an estimated 1 trillion metric tons of carbon and 55 billion metric tons of nitrogen. Historically, the northern permafrost region has.....»»
A machine learning-based approach to discover nanocomposite films for biodegradable plastic alternatives
The accumulation of plastic waste in natural environments is of utmost concern, as it is contributing to the destruction of ecosystems and is causing harm to aquatic life. In recent years, material scientists have thus been trying to identify all-nat.....»»
