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.....»»
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.....»»
Study uncovers the role of soil microbes in forest ecosystems
Assessing the function of forest ecosystems requires a deep understanding of the mechanisms of soil nitrogen mineralization. A study conducted by a team of researchers has shed light on how soil N-cycling genes drive soil nitrogen mineralization duri.....»»
A model to promote the coordination between environmental protection and agricultural development in Erhai Lake
Erhai Lake, covering 252 km2, located in Yunnan Province, is one of the seven largest freshwater lakes in China. However, over the last three decades, the lake has suffered pollution episodes. In order to solve this problem, the local government has.....»»
Africa"s iconic flamingos threatened by rising lake levels, study shows
It is one of the world's most spectacular sights—huge flocks or "flamboyances" of flamingos around East Africa's lakes—as seen in the film "Out of Africa" or David Attenborough's "A Perfect Planet.".....»»
Q&A: El Niño drought leaves Zimbabwe"s Lake Kariba only 13% full—a disaster for people and wildlife
Water levels at Lake Kariba in Zimbabwe have dropped dramatically because of the latest El Niño drought. The country's president, Emmerson Mnangagwa, has declared a national disaster......»»
Scientists discover first nitrogen-fixing organelle
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recen.....»»
Researchers find a new organelle evolving
A "nitroplast" converts nitrogen from the air to a chemically useful form. Enlarge / A photo of Braarudosphaera bigelowii with the nitroplast indicated by an arrowhead. (credit: Tyler Coale) The complex cells that under.....»»
It just became the perfect time to buy a last-gen Intel CPU
Intel made an unexpected decision regarding its 13th generation of processors, which is why now is a good time to buy a Raptor Lake CPU......»»
Tropical coral-infecting parasites discovered in cold marine ecosystems
Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research from University of British Columbia botanists......»»
Officials brace for "uncertainty" in water transfers to Lake Mead
Key backup tubes inside the Glen Canyon Dam might be damaged, potentially threatening the delivery of water to Lake Mead in the future if water levels ever dip too low in Lake Powell, according to a Bureau of Reclamation memo......»»
Earthquakes may not be primary driver of glacial lake outburst floods
Glacial lakes form when meltwater is trapped behind a dam, usually glacial ice, bedrock or a type of moraine (terminal types being an unconsolidated pile of debris at the maximum extent of the glacier). When a dam fails, the resulting sudden release.....»»
