Background It is now apparent that the complex microbial communities found on and in the human body vary across individuals. What has largely been missing from previous studies is an understanding of how these communities vary over time within individuals. To the extent to which it has been considered, it […]

Rising atmospheric CO2 concentrations may alter the nitrogen (N) content of ecosystems by changing N inputs and N losses, but responses vary in field experiments, possibly because multiple mechanisms are at play. We measured N fixation and N losses in a subtropical oak woodland exposed to 11 years of elevated […]
Ecoss studies the interactions of plants with their physical and biotic environments at a fundamental level common to all organisms: gas exchange, energy balance, and water relations. We explore how plants make a living in diverse environments ranging from deserts to rainforests. A longstanding interest is the biophysical and ecological […]
On January 5th, Bruce Hungate presented at Science on Tap at the Green Room, Flagstaff. Featuring an update on the Paris agreement (COP21), new science, legal intrigue, and what Elvis can teach us about climate models.
Global change affects plants and soil in ecosystems across the globe. By doing so, it can alter the composition of ecosystems and the functions they provide. For instance, even small changes in plant growth and soil properties can have a large impact on the amount of CO2 and other greenhouse gases in the atmosphere. At Ecoss, we use field experiments to manipulate the temperature, rainfall and other environmental factors in various ecosystems. This allows us to mimic future conditions, and helps us understand how future ecosystems will differ from the ones today. (more…)
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 […]
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.
Heat waves in Arizona: Do microbial symbionts buffer the effects of heat waves?
The “Multiple Dimensions of Bioscience” Travel Award supported Rachel Rubin’s travel to Evolution 2015, the joint annual meeting of the Society for the Study of Evolution (SSE), the Society of Systematic Biologists (SSB), and the American Society of Naturalists (ASN) in Guaruj, Brazil.
The American Society for Microbiology awarded the 2015 FEMS-ASM Mäkelä-Cassell Award to Ember Morrissey, Ph.D. Morrissey will be presenting her latest, groundbreaking research at the Federation of European Microbiological Societies (FEMS) 6th Congress of European Microbiologists hosted this year in Maastricht, the Netherlands, on 7–11 June. Morrissey is currently a […]
