Earth’s ability to absorb nearly a third of human-caused carbon emissions through plants could be halved within the next two decades at the current rate of warming, according to a new study in Science Advances by researchers at Northern Arizona University (NAU) and the University of Waikato, New Zealand. Using […]
In a year in which global temperature and atmospheric carbon dioxide records were broken, experts from 20 colleges and universities will gather virtually November 17-19, 2020 at Northern Arizona University to discuss why carbon reduction is critical to their institutions’ futures, and how each is forging a path to zero […]
PhD and MS positions in Ecosystem Ecology are available in the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University. Graduate student benefits include a stipend (teaching assistantship or research assistantship), tuition waiver, health insurance, and payment of non-tuition fees. The Ecoss mission is to conduct high-impact, innovative […]
If the fate of carbon is a test that planet Earth is taking right now, one of the answer keys is likely to be found in soil, where microorganisms—which account for nearly 15 percent of global biomass, by some estimates—eat, store and respire carbon and other nutrients. As Earth warms, […]

Plants store nonstructural carbohydrates (NSCs), such as sugars and starch, to use as carbon and energy sources for daily maintenance and growth needs as well as during times of stress. Allocation of NSCs to storage provides an important physiological strategy associated with future growth and survival, and thus understanding the […]
Ecoss graduate student Ali Martinez and a team of ecologists including her advisor Marks, Ecoss researchers Ben Koch and Zasha Welsh, Alex Flecker (Cornell University) and Steve Thomas (University of Nebraska) constructed a system of miniature streams whose temperatures Martinez can manipulate. The team studies how nutrients will move in […]
Eight Ecoss students, faculty, and staff traveled to Detroit, MI in May 2018 to present their research at the Annual Meeting of the Society for Freshwater Science. Undergraduate researcher Zasha Welsh presented a poster, as did graduate students Courtney Roush, Meghan Schrik, Jack Torresdal, and Adam Siders. Ben Koch, Victor […]
A team of scientists from Northern Arizona University’s Center for Ecosystem Science and Society (Ecoss) and Lawrence Livermore National Laboratory (LLNL) recently announced a major achievement in ecosystem science. Their research, published as “Estimating taxon-specific population dynamics in diverse microbial communities” in the journal Ecosphere, illustrates a powerful new technique […]
“NAU Regents’ Professor Bruce Hungate, director of the Center for Ecosystem Science and Society (Ecoss), recently joined a new initiative lead by LLNL to study how the soil microbiome controls the mechanisms that regulate the stabilization of the organic matter in soil. “How do different kinds of microorganisms in the soil grow? How […]
