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 […]
Soil is a complex ecosystem with diverse microenvironments ranging from bulk soil with low quality substrates and no or very limited microbial growth, to high quality C-rich environments near decomposing litter and rhizosphere where microbial growth and death rates are high. Soil contains different microbial communities, supports varying microbial activities […]
Ecoss studies the microbial communities of the human body and the implications for disease including STDs and HIV, as well as analyzing the microbial community using bioinformatics, community ecology theory and Bayesian statistical modeling.
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?
We study soil microbial communities in Antarctica, microbes in hot spring ecosystems in Tengchong, China, methane production at Axel Heiberg Island near Greenland as an analog for life on other planets, and the distribution of soil microbial communities across the arid Southwest.
As part of a large interdisciplinary team, with funding from the National Science Foundation, we have studied how genetic and environmental factors affect leaf litter quality in cottonwoods and other riparian species, and how these effects are manifest in aquatic ecosystems.
