As increasingly severe wildfires burn more of the North American West each year, how people living there use fuel treatments, such as prescribed burns or planting fire-resistant trees around their homes, can determine how destructive fires will be to communities. The National Science… Read more
Team of NAU paleoclimatologists contribute to major report by Intergovernmental Panel on Climate Change, forming scientific underpinnings for negotiations to limit carbon emissions worldwide
The Intergovernmental Panel on Climate change (IPCC) has just released its latest major assessment report on global climate change, approved by the world’s… Read more
Scientists at Northern Arizona University, Arizona State University, the Arizona Geological Survey at the University of Arizona and the National Snow and Ice Data Center at the University of Colorado Boulder have been awarded almost $2 million from the National Science Foundation to develop a virtual reality teaching tool called Polar Explorer. In this… Read more
Drought—even in a single year—can leave aspen more vulnerable to insect infestation and other stressors decades later, a new study by NAU researchers found. Aspen trees that were not resilient to drought stayed smaller than others, growing more slowly and succumbing to an outbreak of insects known as aspen leaf miners that have plagued interior Alaska for more than two decades.
The findings, led by research specialist Melissa Boyd and Regents’ professor Michelle Mack of the Center for Ecosystem Science… Read more
Predatory bacteria—bacteria that eat other bacteria—grow faster and consume more resources than non-predators in the same soil, according to a new study from Northern Arizona University. These active predators, which use wolfpack-like behavior, enzymes, and cytoskeletal “fangs” to hunt and feast on other bacteria, wield important power in determining where… Read more
More severe and frequent fires in the Alaskan boreal forest are releasing vast stores of carbon and nitrogen from burned trees and soil into the atmosphere, a trend that could accelerate climate warming. But new research published this week in the journal Science shows that the deciduous trees replacing burned spruce… Read more
