Biogeochemical cycling of nutrients along the land-river continuum: implications for eutrophication risk, resilience and recovery
Tuesday, 7 May 2024, 3 p.m.Seminar Room 1, Brückstr. 3a, Magdeburg
Nutrients (nitrogen, N, and phosphorus, P) from agriculture and domestic wastewater, are a major cause of eutrophication and water-quality impairment. Nutrient biogeochemical cycling processes along the land-river continuum can play an important role in regulating downstream nutrient transport, mediating nutrient supplies to receiving waters. Nutrient cycling processes are often quantified from relatively short-term, localized process measurements, which can be challenging to extrapolate in space and time. Hydrochemical monitoring, combining ambient tracers, stoichiometry and water body metabolism, offer opportunities to explore the cumulative effects of nutrient sources and biogeochemical cycling processes on downstream nutrient transmission. Using hydrochemical case studies from Canada, the U.S. and the U.K., this presentation will explore nutrient retention and release along the land-river continuum, and the implications for nutrient legacies, nutrient source apportionment, and eutrophication risk, resilience and recovery. Consequently, to protect river biota, a shift to more sustainable agricultural practices like reducing pesticide application is urgently required. Lina Stein
Research gaps and research needs - Mining the scientific literature reveals global biases in hydro-hazard research
Monday, 26 February 2024, 3 p.m.
room E01 A, Theodor-Lieser-Straße 4, Halle
Dr Lina Stein is a postdoctoral researcher at the University of Potsdam in the Analysis of Hydrologic Systems group. Her research focus is knowledge synthesis in hydrology, where she uses text-as-data methods to extract hydro-hazards knowledge. She was awarded her PhD from the University of Bristol, UK, in 2021 for her thesis on flood generating processes. She has a background in environmental science and hydrology from her degrees at the University of Freiburg, DE.

Changing life in lakes - human impacts on trophic interactions
Monday, 19 February 2024, 3 p.m.
Brückstraße 3a, 39114 Magdeburg, Seminar Room
The Anthropocene is characterized by rapidly changing environments. Human activities have caused or intensified stress on ecological communities and the species within them. Stressors, influencing survival and reproduction, result in altered selective pressures on organisms. Adaptive responses to altered selection pressure can range from physiological phenotypic plasticity to changes in the microbiome, and evolutionary adaptation. These responses can in turn feedback on ecological processes at the population and community level with consequences for the entire ecosystem functioning. Adaptive responses to stress can prevent or promote abrupt transitions between alternative stable states of ecosystems. Understanding the complexity of interacting ecological and evolutionary processes ecological communities use to deal with their changing world is highly needed if we want to predict, plan for, and manage societal effects of climate change.
Join me here in exploring how ecosystem change can lead to evolutionary change in plankton communities of lake ecosystems.

Long-term ecological research project REES - Using genomics to measure freshwater eco-evolutionary processes in the field
Monday, 22 January 2024, 3 p.m.
Brückstraße 3a, 39114 Magdeburg, Seminar Room
How do freshwater ecosystems react to changing environmental conditions and to what extent can
these changes be captured in the dynamics of eco-evolutionary processes? The project REES ('Rhine
Eco-Evolutionary System') aims at the long-term assessment of eco-evolutionary interactions in the
Rhine as a limnic habitat under consideration of diverse associated water bodies. The study area
includes the main flow channel of the Rhine (km 845, North Rhine-Westphalia), as well as Rhine
oxbows, Rhine water-fed gravel pit lakes in ecological succession and the surrounding floodplain
(Rees, district of Kleve). The extensive system of standing and flowing freshwater bodies covered in
the REES study site allows the investigation of dynamic variations in biodiversity composition at all
levels, from species diversity of communities to genomic diversity at the molecular level of individuals
and populations. Along a selected trophic cascade, representative species will be long-term observed
and analysed ecologically and especially also (population-)genomically. The incorporation of
ecological genomics is the core aspect of this LTER-D (German network of the Long-Term Ecological
Research) project, which is intended to capture the feedback of evolutionary changes on the
ecological system. Population genomic approaches can be used to infer both evolutionary and
ecological processes from genomic data. To cope with the dimension of this project, REES is
designed as an interdisciplinary collaboration project and currently counts four project partners with
corresponding subordinate projects.
