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 […]
The tiny cosmos of organisms living on a streamer of algae in a river—the algal microbiome—could help scientists learn what turns an environment from healthy to toxic and back again. A multidisciplinary team led by Northern Arizona University has won $3 million from the National Science Foundation to translate the […]
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 […]
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 […]
Organic matter input to soils can accelerate the decomposition of native soil carbon (C), a process called the priming effect. Priming is ubiquitous and exhibits some consistent patterns, but a general explanation remains elusive, in part because of variation in the response across different ecosystems, and because of a diversity […]
Warming global temperatures are changing life on every continent on Earth, including Antarctica, where more microbes are moving in to territory previously covered by ice. How these microbes respond to warming offers us clues about what future Antarctica will look like and who will thrive there. Microbial ecologist and PhD […]

Wired red oak is first of its kind in North America. As trees across the U.S. continue their picturesque march toward autumn, one 100-year-old oak tree in Massachusetts is attracting a crowd of admirers online. The tree is a scientific wonder—not because of its unique looks or a special way […]
Global terrestrial nitrogen (N) and phosphorus (P) cycles are coupled to the global carbon (C) cycle for net primary production (NPP), plant C allocation, and decomposition of soil organic matter, but N and P have distinct pathways of inputs and losses. Current C-nutrient models exhibit large uncertainties in their estimates […]
The research team, led by Bradley Butterfield from NAU’s Center for Ecosystem Science and Society (Ecoss) and including Scott Anderson from the School of Earth and Sustainability, found that a plant’s evolutionary build—its growth form (tree vs. shrub) and how its seeds are dispersed—are strong predictors of how quickly it […]
