Ecoss researcher Michelle Mack is leading a $1 million NASA-funded project to measure the extreme fire activity in boreal forests and its effects on arctic tundra. Based on the number of acres burned, 2015 is shaping up to be the second most extreme fire year during the past decade in North […]
Northern Arizona University: PhD and MS positions in Ecosystem Ecology are available in the Center for Ecosystem Science in Society (Ecoss) at Northern Arizona University. The Ecoss mission is to conduct high-impact, innovative research on ecosystems and how they respond to and shape environmental change, to train next-gen scientists, and […]
Winter 2016 Prospective Student Retreat Was Great Ecoss hosted prospective graduate students for a two day visit this winter in February. The next Student Retreat will take place in the winter/spring 2017. Check back here for details as they become available. Attendance was by invitation only, and prospective students had […]
Michelle Mack describes the effects the wildfires in Alaska this summer will have on the carbon emissions from permafrost in this story in the Washington Post. “Beyond the direct carbon emissions from fire, loss of the insulating organic layer is likely to destabilize permafrost, leading to thaw, decomposition and release […]
When new carbon enters soil, especially carbon that is easily assimilated and decomposed by soil microorganisms, a chain reaction occurs leading to the breakdown of older soil carbon, carbon that would otherwise have remained stable. Current theory does not explain this chain reaction, sometimes called the “priming effect.” But understanding […]
We study antibiotic resistance in human pathogens, genetic sampling of meat for antibiotic resistance, methods to develop a molecular database for strains of E. coli in urinary tract infections, and food safety of kosher vs non-kosher chicken.
Heat waves in Arizona: Do microbial symbionts buffer the effects of heat waves?
Bruce Hungate, Director of Ecoss gave the keynote address to the Goldschmidt Conference in Prague this week for the session, “How do Biogeochemical Cycles Operate on a high-CO2 Planet?” The abstract for Dr. Hungate’s keynote address was entitled “Rising CO2 and the Biogeochemistry of Soil Microbial Ecosystems.”
NAU professor and a team of researchers are seeking to better understand staph bacteria, information that could lead to reductions of the potentially lethal pathogen. Abstract The human microbiome can play a key role in host susceptibility to pathogens, including in the nasal cavity, a site favored by Staphylococcus aureus. […]
