Interviewed by STICH Scholar and Ecoss social media specialist Kayla Blair. Meet Vic Monsaint-Queeney, a PhD candidate in Bruce Hungate’s lab! Here, Vic studies bacteria in the soil on the San Francisco Peaks in Flagstaff, where she looks at the different types of nitrogen that these microbes consume. The research involves […]
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 […]
The Center for Ecosystem Science and Society (Ecoss) at NAU has been named one of 15 new partner institutions of the AGU Bridge Program, which works to support students in applying to and succeeding in graduate school in the Earth sciences. Ecoss and the other new partner groups join a […]
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 […]
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 […]
Moss-associated N2 fixation provides a substantial but heterogeneous input of new N to nutrient-limited ecosystems at high latitudes. In spite of the broad diversity of mosses found in boreal and Arctic ecosystems, the extent to which host moss identity drives variation in N2 fixation rates remains largely undetermined. We used […]
Globally, soils store two to three times as much carbon as currently resides in the atmosphere, and it is critical to understand how soil greenhouse gas (GHG) emissions and uptake will respond to ongoing climate change. In particular, the soil-to-atmosphere CO2 flux, commonly though imprecisely termed soil respiration (RS), is […]
Large-scale vegetation restoration projects pose threats to water resource security in water-limited regions. Thus, the quantification of how vegetation cover affects soil moisture is of key importance to support effective restoration schemes in drylands. However, the current understanding of such effects remains poor. For this study, an in-situ vegetation-removal experiment […]
