Soil microorganisms and plants are key players in the production and breakdown of organic matter, and together control global biogeochemical cycles of carbon, nitrogen and phosphorus. TER, the Division of Terrestrial Ecosystem Research, aims to advance our fundamental understanding of how plants and soil microorganisms respond to, and in turn shape, their abiotic and biotic environment, and to determine the consequences for the functioning of Earth’s ecosystems.
Research Mission
Primarily dedicated to basic research, TER addresses pressing environmental issues, such as the impact of climate and land-use change on ecosystem functioning and the role of soils in the global carbon cycle and in food security. In doing so, we work on scales from µm (i.e. the scale at which microbes operate) to the biosphere (i.e. where plant and microbial processes become evident), and in ecosystems spanning the Arctic tundra to tropical rainforests. We integrate this scale of thinking with state-of-the-art methods, including stable isotope tracing and biomarker fingerprinting, and are developing novel approaches to estimate gross environmental processes with isotope pool dilution techniques.
We are strongly committed to conduct world-leading research in a motivating and intellectually stimulating environment, and to train our students to become independent and internationally competitive scientists who enjoy research and contribute to society as conscientious citizens.

Research Projects
The Biogeochemistry of Tungsten (W) in the Plant-Soil Environment
In the past decades, increasing industrial and military use of Tungsten (W)-based products opened new pathways of W into natural systems and raise the need for a better understanding of the behaviour of W in the environment. Soils play a particularly important role in controlling the bioavilability of pollutants and their entry into the food web via plant uptake as they serve as filter and buffer systems.
This project therefore aims at providing crucial information on W solubility, speciation and partitioning in soils governed by important soil chemical properties like pH. Considering the chemical similarity of W and Mo, an essential micronutrient involved in the plant N cycle, we will also explore W uptake and partitioning within the plant and the effect of elevated W concentrations on plant biomass production, N assimilation, symbiontic N2 fixation and on plant metabolic reactions. By combining conventional techniques with novel methods and high-end analytical tools (NanoSIMS, LA-ICP-MS) this project will deliver completely new insights into the behaviour of W in natural systems and provide valuable information on W fluxes in the plant-soil environment.
