Production and consumption of greenhouse gases by microorganisms Jamie.Brown@nau.edu

    Brown’s research focuses on predicting feedbacks to global change through the production and consumption of the greenhouse gasses CO2, CH4, and N2O by microorganisms across multiple ecosystems. Brown has also participated in research into carbon and nitrogen cycling by microorganisms in geothermal springs through stable isotope probing.

    Brown hopes to contribute to the understanding of dynamic microbial processes through the development of innovative in-situ measuring techniques.

    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.
