Vic Monsaint-Queeney, PhD candidate

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 SCATTERPLOT DEPICTS HOW MUCH CARBON OR OXYGEN ISOTOPE DIFFERENT SOIL BACTERIA TOOK INTO THEIR DNA (A PROXY FOR GROWTH) DURING A 7-DAY EXPERIMENT. SMALL POINTS REPRESENT THE GROWTH OF INDIVIDUAL BACTERIAL STRAINS LINKED BY LINES TO THE AVERAGE GROWTH OF THEIR CLOSEST IDENTIFIED GENUS. COLORS WERE ASSIGNED BY A CLUSTERING ALGORITHM TO GROUP GENERA INTO FAST-GROWING OR SLOW-GROWING LIFESTYLES.

Lifestyles of the fast and slow (bacteria): In the wild, most live in the slow lane

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 […]

A trio of illustrated panels depicts the soil microbial communities in three treatments of a long-term warming experiment north of Flagstaff, Arizona. The panels are labeled in gray text, left to right: control, short-term warming, long-term warming. The control treatment, far left, depicts bacteria, protists, and other microorganisms identified by sequencing the soil’s metagenome in yellow, orange, green, and blue, along with chains of available nutrients. Soil depicted in the center panel, which has undergone short-term warming, shows an increased abundance and diversity of microbes, some of which are growing, incorporating nutrients, and respiring carbon dioxide. The soil that has undergone long-term warming, imagined in the panel on the right, shows fewer microbial species and competitive relationships that are developing for control of the scarcer nutrients.

Does a warmer future favor microbial friend or foe? Ecoss researchers win $3.4M to study interactions in changing soil

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 […]

Haley Dunleavy, PhD ’21

“When I decided to pursue a career in science, my vision of what it would entail was hazy, to say the least. From growing up watching NOVA on PBS to exploring the ecological diversity of deserts, glaciers, coasts, and tundra during my undergraduate career, I knew that science excited me. […]

What the future looks like: NAU student creates tool to make modeling easier for ecologists

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 […]

Earth to reach temperature tipping point in next 20 to 30 years, new NAU study finds

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 […]
