FRAM-seminar: How to measure multiple environmental stressors

Empirically testing the effects of all possibly co-occurring stressors and chemical mixtures is rendered impossible. Thus, theoretical advances of our predictive capacities are urgently needed. Professor Ralf B Schäfer is an expert on exposure and effects of different environmental stressors and will present two ways to deal with these phenomena.

Professor Dr. Ralf B. Schäfer (Phd 2008), working group leader in Quantitative Landscape Ecology, is professor at the University Koblenz-Landau since 2010 in the Institute for Environmental Sciences. His main expertise has particular emphasis on organic toxicants, on freshwater invertebrates, microbes and ecosystem functions using field investigations and different statistical and spatial modelling techniques. He has published over 80 articles in international peer-reviewed journals including leading multidisciplinary journals.

The current epoch is characterised by an unprecedented influence of human societies on ecosystems through multiple anthropogenic stressors. These stressors range from habitat degradation over invasive species to pollution including by toxicants. The co-occurrence of these stressors is rather the norm. Moreover, given that approximately 30,000-70,000 chemicals are in daily use and many such as pesticides are deliberately emitted, environmental chemical exposure alone is often characterised by the co-occurrence of multiple chemicals.

Professor Ralf B. Schäfer will first present recent studies on the co-occurrence of stressors and chemicals in the field and present two research avenues to deal with these phenomena: 1) Prioritisation of mixtures and stressors and 2) Advancement of predictive capabilities using theoretical models.

The FRAM-seminar will take place on Vasaplatsen 1, Jan 31, 9.00-12.00.
