Researchers used charcoal found in lake sediment records to assemble the fire history across the Rocky Mountains. They discovered that, since 2000, wildfires are burning nearly twice as much area, on average, compared to the last 2,000 years.
A study of woodland ecosystems that provide habitat for rare, endangered species along streams, rivers throughout California reveals some ecologically important areas are inadvertently benefitting from water humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term survival of natural communities and spotlights the need for changes in the way water is managed across the state.
Researchers at the University of Central Florida have published a first- of-its-kind study that shows that near-infrared (NIR) spectrum cameras can help python hunters more effectively track down these invasive snakes, especially at night.
New research led by scientists from the Max Planck Institute for the Science of Human History shows that disruptions to Indigenous land management following Iberian colonization did not always result in widespread forest regrowth in the Americas and Asia-Pacific, as has been recently argued.
The fairy circles of the Namib are one of nature's greatest mysteries. Millions of these circular barren patches extend over vast areas along the margins of the desert in Namibia. An early hypothesis by G.K. Theron was that poisonous substances from Euphorbia damarana leaves induced fairy circles. Now new research at Göttingen University and the Gobabeb Namib Research Institute found the original experiment and, 40 years later, the researchers are able to conclusively disprove this hypothesis.
Parts of the Amazon have been cultivated by Indigenous peoples for thousands of years, and mere centuries ago were the sites of cities and farmland, but other parts are "untouched." By examining microscopic bits of plant remains and charcoal in the soil, scientists learned that the Putumayo region of Peru's plant life hasn't changed much in 5,000 years, meaning that the people who have lived there found a long-term way to co-exist with nature.
Louisiana State University marine geologist and paleoclimatologist Kristine DeLong's new research findings uncover new information about the underwater ancient cypress forest and the Gulf Coast's past.
Good acoustics in the workspace improve work efficiency and productivity, which is one of the reasons why acoustic materials matter. The acoustic insulation market is already expected to hit 15 billion USD by 2022 as construction firms and industry pay more attention to sound environments. Researchers at Aalto University, in collaboration with Finnish acoustics company Lumir, have now studied how these common elements around us could become more eco-friendly, with the help of cellulose fibres.
Global land-use changes -- including forest fragmentation, agricultural expansion and concentrated livestock production -- are creating "hot spots" favorable for bats that carry coronaviruses and where conditions are ripe for the diseases to jump from bats to humans, finds an analysis published this week by researchers at the University of California, Berkeley, the Politecnico di Milano (Polytechnic University of Milan) and Massey University of New Zealand.
Swedish researchers from institutions including Uppsala University have spent four years gathering data from the areas affected by the major forest fire of 2014. In their study of how the ecosystem as a whole has been altered, they could see that water quality in watercourses quickly returned to normal, while forested areas continued to lose carbon for many years after the fire.
