Quantification of aboveground biomass (AGB) in Alaska’s boreal forest is essential to the accurate evaluation of terrestrial carbon stocks and dynamics in northern high-latitude ecosystems. Our goal was to map AGB at 30 m resolution for the boreal forest in the Yukon River Basin of Alaska using Landsat data and […]

A study led by Northern Arizona University offers new evidence that a common framework to sort bacteria into two lifestyles doesn’t easily apply to bacteria living in wild soil. The findings, published in The ISME Journal, show that rather than bacteria falling into two major lifestyle groups—one adapted to be competitive and […]
In 2002, the Odyssey probe discovered evidence of past ice on Mars. The U.S. Congress authorized the Iraq War resolution. The Anaheim Angels won the World Series. And in a meadow 15 miles north of Flagstaff, scientists began to monitor and move small plots of soil along a mountain gradient […]
Xin Huang wants to make modeling and using big data easier for everyone, especially ecologists who don’t have extensive computer programming experience. As a third-year doctoral student in the Center for Ecosystem Science and Society at Northern Arizona University, Huang saw a technical barrier between the earth system modeling community […]
As the Arctic endures another summer of record-breaking surface air temperatures, a team from NAU, led by Ecoss’ assistant research professor Christina Schädel, has been awarded a three-year, $764,000 grant from the Department of Energy to help improve models that predict what will happen to permafrost carbon as the Arctic […]
On a recent weekday morning, I logged on to a zoom session of Mrs. Mathew’s summer science class at Greyhills Academy High School in Tuba City. A picture of two giant heaps of soil appeared on the screen, and then an image of Grand Prismatic Spring in Yellowstone National Park. […]
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 out this week 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 […]
Rubber powdery mildew caused by the foliar fungi Oidium heveae is one of the main diseases affecting rubber plantations (Hevea brasiliensis) worldwide. It is particularly serious in sub-optimal growing areas, such as Xishuangbanna in SW China. To prevent and control this disease, fungicides causing serious environmental problems are widely used. […]
Unique soil properties in rhizosphere can affect plant growth and biogeochemical cycles of ecosystems. While rhizosphere has been widely investigated, little is known about differences in the rhizosphere effect (RE) between co-existing overstory trees and understory shrubs and herbs in forest ecosystems. In this study, we investigated REs on soil […]
