Frontiers in experimental research on changing environments
Leipzig / Bad-Lauchstädt, Germany
We are pleased to invite you to join us in Leipzig, Germany, from 7 till 9 June 2022 for the conference “Frontiers in experimental research on changing environments” The conference is jointly organized by the Helmholtz-Centre for Environmental Research – UFZ and the German Centre for Integrative Biodiversity Research – iDiv.
Experimental ecosystem research contributes significantly to better understanding how terrestrial ecosystems respond to human-induced environmental change, to deciphering the mechanisms behind these responses, and to enabling more sustainable land-use practices. During our conference, we will discuss the current status and the progress of field experiments in ecological and environmental research on a global scale. Symposium topics range from the effects of land-use change, climate change, air and soil pollution, and nutrient inputs on ecosystems to changing biodiversity and interactions in the above- and below-ground soil-plant system.
With this conference, we will also celebrate more than one century of experimental agricultural and environmental research at the Bad Lauchstädt field station since 1895. Important field experiments at our field research station range from the Static Fertilization Experiment set up in 1902 to the Global Change Experimental Facility (GCEF) established in 2013, and include numerous other small and larger field experiments. By now, the Bad Lauchstädt field station has become an important site of experimental ecosystem research around land use and climate change and the consequences for the soil-plant-atmosphere system, its functions and services - for the UFZ, the iDiv and numerous research partners from Germany and abroad.
With our virtual tour map you can already have today an overview of the all current research projects in Bad Lauchstädt. The experimental ecosystem research was also a cover story in our “UMWELTPERSPEKTIVEN”.

Academic career and research areas
Soil processes and soil management, especially the type and intensity of land use, affect the global carbon cycle. Prof. Kögel-Knabner (b. 1958) investigates the formation, composition and properties of organic matter in soils and their central role in the global carbon cycle. She uses sophisticated spectroscopic methods, such as 13C NMR spectroscopy and nanoSIMS, to investigate the association of organic and mineral matter in soils at the submicron scale. Prof. Kögel-Knabner studied geoecology at the University of Bayreuth, where she also obtained a doctorate in soil science (1987) and earned her post-doctoral teaching qualification (Habilitation 1992). In 1991, she was appointed to a professorship for soil science and soil ecology at the Ruhr-Universität Bochum. Since 1995, she has served as Chair of Soil Science at TUM. Prof. Kögel-Knabner is a member of academies (Leopoldina, acatech, Bavarian Academy of Sciences) and was member of the Bioeconomy Council of the German Federal Government. Since 2015, she has been on the list of "Highly Cited Researchers", and counts among the most cited scientists in the world.

Research interests• Biodiversity
• Ecosystem functioning
• Ecosystem services
• Nutrient enrichment
• Land use changes
• Exotic species
• Extreme climatic events
I am broadly interested in questions at the intersection of community and ecosystem ecology. I use field experiments to investigate the causes and consequences of changes in plant diversity, often in grasslands at Cedar Creek Ecosystem Science Reserve. I also lead synthesis studies across many ecosystems to determine the generality of our findings at Cedar Creek.
To understand the causes of changes in plant diversity, I study how biodiversity responds to anthropogenic drivers, such as land use changes, nutrient enrichment, exotic species invasions, and extreme climatic events. I am particularly interested in whether cessation of these anthropogenic perturbations leads to recovery of biodiversity, or whether the community remains stuck in a depauperate state. To understand the consequences of changes in plant diversity, I study how ecosystem functioning (for example, productivity) and ecosystem services (for example, carbon storage for climate regulation) respond to changes in plant diversity. I am now combining these efforts to quantify the extent to which anthropogenic drivers influence ecosystem processes by restructuring communities and altering biodiversity.

I am a community ecologist interested in how natural and human global change drivers affect populations, communities and ecosystems at different spatial and temporal scales. My research falls into three broad categories;
- How do local and regional processes interact to shape the patterns in diversity, abundance and function that we observe in nature?
- How does environmental changes affect plants, and how do these effects scale across levels of organization from individuals via populations to communities?
- What are the impacts of human land-use regimes, past and present, on terrestrial ecosystems?
I study these topics by a combination of of laboratory experiments, field experiments, and field observations. Through my own research projects and collaborations in Norway, Europe, the US, Uganda, Nepal, China, and Peru I get the opportunity to explore these questions in different regions, study systems, and by using different methods.
I have also worked with nature management and conservation authorities in Norway, with IPBES, and the UNESCO-recognised Heathland Centre at Lygra to explore science-policy links relating to my research.

Land-use change is one of the major drivers affecting terrestrial ecosystems, including both the above-ground and the soil sub-system. This includes changes in the type of land-use such as the transformation of (semi-)natural ecosystems into arable land, but also the change in land-use intensity and the fragmentation of whole landscapes. In this session, we will present and discuss recent experimental results and the variety of experimental approaches to understand and mitigate ecosystem responses to land-use change.
Despite international agreements on goals to limit the increase in global temperatures by reducing anthropogenic greenhouse gas emissions, there is an undamped change of climatic factors. The unprecedented speed of climate change has been shown to cause strong changes in the structure and dynamics of ecosystems as well as the services they provide to humankind. In this session, we will present empirical approaches to assess the consequences of climate change for ecosystems including agricultural systems.
Pollution of air, soil, and water by a variety of chemical compounds originating, for instance, from industry, agriculture or transportation are one of the major threats to biodiversity and whole ecosystems. This includes in particular the atmospheric deposition of nutrients which may lead to ecosystem eutrophication with profound effects on aboveand below-ground communities, on food webs, and on matter cycling. We will discuss recent results and highlight experimental advances to understand and forecast ecosystem responses to pollution by nutrients and other chemical substances.
non-additive. However, we still have profound knowledge gaps regarding the mechanistic basis of both, the context-dependency of, and the interaction between effects of global change drivers on terrestrial ecosystems. This session will discuss recent experimental results as well as methodological advances to better understand variation in ecosystem responses and interactive effects among drivers.
Our experimental research has already led to a profound understanding of ecosystems and their critical regulating
processes. A current challenge is to use this knowledge to develop mechanistic model concepts that allow us to predict how ecosystems of the future will respond to possible future environmental scenarios and conditions. We will discuss the current state and recent developments in predictive modelling of ecosystem processes and functions.
