NREL Fall 2009 Seminar Series
"Using stable isotopes to understand ecological processes and global change"
Stable isotopes have proven to be a powerful tool to study ecosystems, their functioning and responses to global changes, because they create a non-disruptive window through which we can study processes and follow the fate of specific element. Stable isotope studies are in fact now largely contributing to the fast advancement of knowledge in ecology, ecosystem and atmospheric science. For this seminar series, speakers will guide us through the use of isotopes, by presenting a diverse set of case studies where improved understanding of plants, animals, microbes, soils and the atmosphere come through measures and models of stable isotopes. Additionally, on November 13th Dan Reuss will host an open lab event at the new NREL Stable Isotope facility, and inform us about the large array of isotopic and conventional analyses that lab can do.
Lectures will be in the NESB Francis Clark Conference Room B215, at 11 a.m. - noon, unless otherwise noted. Talks will be limited to 35 minutes to allow ample time for questions, suggestions, and discussion.
