Bruce Hungate, Ecoss Director, Regents’ Professor, and McAllister Chair in Community, Culture, and Environment is presenting in Science on Tap on ‘Climate Change and Culture on the Colorado Plateau‘. How will climate change affect our region? How can we respond? Explore the science of climate change, its relationship to society […]
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.
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.”
Fossil Creek Restoration Can we restore a river after a century of disturbance? Research in the Marks Lab has addressed the following questions: How did native species respond to restoration? Employing a BACI design (Before After Control Impact), we determined the relative importance of flow restoration versus non-native fish removal […]
Overview Fire, a natural ecological disturbance, has been suppressed in U.S. forests for much of the past century. This has prevented damage to property and protected timber resources, but has caused many forests to develop in an unnatural manner, resulting in dense stands of small trees that are now poised […]
Overview The identities of organisms profoundly influence ecosystems, and microbial diversity is vast. The obvious disconnect between this diversity and its treatment in C cycling models is perhaps the best manifestation of the common complaint that so much physiology, taxonomy, ecology, and diversity is ignored when microbial communities are described […]
Overview Using a technique called data-assimilation, we can inform existing ecosystem models with measurements from field experiments. In combination with meta-analysis, this approach becomes a powerful statistical tool to improve our predictions of ecosystem responses to global change. We recently used data-assimilation to study the effect of warming and CO2 enrichment on […]
Overview Over the past several decades, scientists have conducted hundreds of experiments investigating responses of ecosystems to global environmental change. Ecoss synthesizes many of these responses using a statistical technique called meta-analysis. This approach considers all the measurements together and quantifies the overall response, testing whether responses vary among ecosystems, […]
Overview Most global change research focuses on individual components, but the environment is changing in multiple ways simultaneously. The Jasper Ridge Global Change Experiment seeks to find out how these combined changes will affect ecosystems. Researchers tested the response of a California grassland to: climate change elevated atmospheric carbon dioxide […]
Soil microorganisms are biogeochemical forces of global significance. They affect nutrient availability to plants, the amount of carbon stored in soils, and the evolution of the atmosphere over geologic time. The research we conduct in Ecoss examines many aspects of soil microbial ecology. Metabolic Flux Analysis of Soil Microbial Communities […]
