Introduction
I am working in the field of soil organic carbon and total nitrogen stocks as well as biogeochemical fluxes and the impact of climate change.
Currently I am studying soil organic carbon stocks in pre-alpine and alpine grassland soils with a focus on grazing-induced changes in soil nutrient stocks, dissolved nutrients, plant above- and below-ground biomass storage, as well as microbial genes. The question hereby is in how far different grazing intensities can support important ecosystem services.

The special issue summarises and highlights key findings of the research unit DASIM funded by the German Research Foundation (DFG) on the process of denitrification. Progress was made in several areas including the development of new and advanced methods to quantify N 2 fluxes such as a new ¹⁵ N gas flux method, enhanced Raman spectroscopy and a ne...
Climate change is inducing loss of soil organic carbon (SOC) and total nitrogen (N) from pre-alpine grasslands, thereby endangering soil functions. At the same time, organic fertilizer
management has been constantly changing, from predominantly farmyard manure to
broadcast spreading of liquid slurry and to recent upper limits of organic N fertili...
Intensive fertilization of grasslands with cattle slurry can cause high environmental nitrogen (N) losses in form of ammonia (NH3), nitrous oxide (N2O), and nitrate (NO3⁻) leaching. Still, knowledge on short-term fertilizer N partitioning between plants and dinitrogen (N2) emissions is lacking. Therefore, we applied highly ¹⁵N-enriched cattle slurr...
The mountain pasture "Bunnenkopfalm" in the German Alps shows a strong grazing-induced increase in SOC stock of ca. 2 t per hectar and year.
Arctic tundra fires have been increasing in extent, frequency and intensity and are likely impacting both soil nitrogen (N) and phosphorus (P) cycling and, thus, permafrost ecosystem functioning. However, little is known on the underlying microbial mechanisms, and different fire intensities were neglected so far. To better understand immediate infl...
Lichens serve as important bioindicators of air pollution in cities. Here, we studied the diversity of epiphytic lichens in an urban area in Munich, Bavaria, southern Germany, to determine which factors influence species composition and diversity. Lichen diversity was quantified in altogether 18 plots and within each, five deciduous trees were inve...
The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in favor of organic N compounds is based on the observation that net N mineralization rates in these cold climates are negligible. However, we find here that this perception is wrong. By synthesizing published data on N cycling in the plant-soil-microbe system...
• The positive effect of global warming on the growth of cyanobacteria has been widely predicted, but long-term studies targeting their adaptive potential to higher temperature have not been carried out so far. Predicting the magnitude and impact of cyanobacterial blooms in the future as a response to global warming requires an understanding of how...
Premise
The proportion of woody dicots with toothed leaves increases toward colder regions, a relationship used to reconstruct past mean annual temperatures. Recent hypotheses explaining this relationship are that (1) leaves in colder regions are thinner, requiring thick veins for support and water supply, with the resulting craspedodromous venatio...
