environments provide essential supporting, regulating, provisioning and cultural ecosystem services. Anthropogenic stressors such as nutrient input from agriculture, pollution, sediment dumping, and user pressures

nutrient uptake in phytoplankton for future net primary production, and time of emergence of anthropogenically induced trends in dissolved organic matter in Earth system model simulations. I am currently

the glomeruli (GL). (Photo: Ulf Bickmeyer) To elicit any effect on living systems, natural and anthropogenic compounds target the smallest unit of the biota, the single cell. Small molecules may act as signaling [...] fluorescent cellular compounds. The aim of this research is to define cellular targets of natural and anthropogenic small molecules. Chemical analysis of secondary metabolites Secondary metabolites are those chemical

Marine Chemistry The Marine Chemistry team investigates the importance of natural and anthropogenic organic substances and nutrients in water and marine organisms and their significance for global material

Bremerhaven, as a container building placed on a platform some meters above the snow. Concerning anthropogenic pollutants, the Antarctic atmosphere is "ultra clean". Thus local pollution by vehicles and the

Biological effects of marine organisms Pollutants of anthropogenic origin have also been polluting our oceans since the industrialization of the world. Coastal seas such as the North and Baltic Seas in

motivation is to identify the nature of the associated aerosol sources (biogenic, geochemical, or anthropogenic) as well as source regions, and to elucidate to what extend the atmospheric signal is authentically

this sudden rise has proven a challenge for researchers. After all, factoring in the effects of anthropogenic influences like the accumulation of greenhouse gases in the atmosphere, of the weather phenomenon
