Biosketch
As an ecologist I am interested in the correlation between species’ body masses and their metabolism and how this correlation is affected by temperature.

Current position
In march 2008, I started my doctoral thesis in the EcoNetLab as a part of the biodiversity exploratories funded by the DFG.

Research interests:
Does the litter-soil community change with the intensity of land use? I am comparing litter-soil communities of differently used forests to see how they are affected by different types of forestry. The focus is on the composition of the communities in these litter-soil systems of differently managed forests. Therefore body sizes, abundances and metabolic rates will be measured and body-size distributions across trophic levels, metabolic demands of populations and population densities across trophic levels as well as in accordance to body mass will be calculated. One of the key questions to be addressed is whether these factors are correlated to the trophic level in the litter-soil system as it has been demonstrated in aquatic systems?
