Birgit Köhler receives the ‘Göttinger Preis Waldökosystemforschung’ for 2011. This award distinguishes excellent works of young researchers in the field of Forest Ecology.
This prize is founded by Prof. Dr. Bernhard Ulrich and is given through the Forest Ecosystem Research Center, Georg-August University of Göttingen. As Prof. Ulrich pioneered the awareness of deleterious effects of high atmospheric acid and N deposition on forests in Germany and laid the ground work for mitigation policy, such awareness of an important global change process has brought the PhD research of Birgit Köhler to Panama. Her research generated one of the leading information on the impact of projected increase in N deposition on trace gas fluxes in forest soils of the tropics.
Her PhD research is summarized in this article: ´Soil nitrogen oxide and carbon dioxide emissions from a tropical lowland and montane forest exposed to elevated nitrogen input´, and is part of the NITROF project, funded by the Robert Bosch Foundation, and was under the guidance of M.D. Corre and E. Veldkamp.
