Robustness and Resilience of Nature‐Society Systems in the evolving Anthropocen

We found a significant deficiency in the interdisciplinary approach to basic and transformational research concerning the interrelated impacts of environmental pollution, biodiversity loss, and climate change.

Despite the substantial amount of research on chemical pollution over the last few decades, it has mostly remained within the domain of ecotoxicology, with little effect on broader ecological fields. Furthermore, there is a lack of social-ecological and social science research addressing the strong interdependence between societies and synthetic chemicals, as well as transformation paths.

Due to the complexity and global nature of this environmental issue, it requires integrated, cross-border research and solution strategies. On the one hand, there is a shortage of research in accurately measuring the effects of new factors on biodiversity and ecosystems. On the other hand, human-caused factors, and potential levers for transformation, such as strategic action fields, relevant actors, and political and economic governance options, need to be examined. 

The RobustNature consortium aims to address the research gaps by providing a comprehensive platform for interdisciplinary and transdisciplinary research.

The goal is to facilitate societal transformation by examining the safe and equitable operating space for new entities, accounting for both the ecological ceiling and the social foundation. This will be accomplished by combining research on novel entities, the resilience of organisms and ecosystems, and the related social activities, needs, and drivers of change.

Considering this, the consortium has developed the following core research question to guide its work: How do environmental pollution, climate change, and land use change interact to impact biodiversity, ecosystem health, and human well-being, and which societal drivers and transformation levers are involved?

Project Description

This project offers a three-months research experience project at the Department Evolutionary Ecology and Environmental Toxicology (E³T), as part of the Institute of Ecology, Diversity and Evolution in the field of behavioral ecotoxicology.

The project aims to characterize behavioral toxicity of emerging contaminants in early life stages of fish. It will compare life-stage specific toxicity of select pesticides and neuro-active pharmaceuticals that are commonly found downstream of agricultural areas or municipal wastewater treatment plants where they pose a potential risk to non-target aquatic vertebrates such as fish. Specifically, the project will assess classic behavioral responses of the model fish species zebrafish (Danio rerio) after short- and medium-term exposure to environmentally relevant concentrations of two pesticides and two pharmaceuticals as well as positive control substances with well-described behavioral effects in fish. Endpoints to be assessed include spontaneous tail coiling activity, scototaxis, geotaxis, shoaling ability and interaction with other individuals.

The student will work with early life stages of zebrafish, and will receive in depth training in behavioral experimental design, analysis of the above fish behaviors using the Zebrabox system and associated software as well as data analysis. 

Requirements

The student must have experience with working with live fish, hold a bachelor degree in biological/animal sciences or a related discipline, and should be currently enrolled in a masters program. Because this project is related to working with livie animals, we expect a strong reliability and diligence. Basic knowledge in the field of ecotoxicology is preferred but not mandatory.

Recommended literature and preparationLiterature related to ecotoxicology, neurotoxicity.

Project Description

The variability in the development of organisms and the flexibility in the interactions of systems comprising multiple organisms are prerequisites for all adaptations to a habitat’s ever-changing conditions. The initial goal of our research is the systematic and quantitative characterization of robustness at the organismic level in a multiscale approach from molecules to ecosystems.

It is essential to determine the fundamental truth of a system. What is its normal state? How much does it fluctuate? When does a system lose its resilience? What happens then? The mean of these values, their variance and their distribution provide the basis for the examination of stressor effects (e.g., changes in temperature, salinity, and moisture levels): How does a “new normal” change as a function of stressor activity? How must ecosystems be adjusted to preserve a system close to its original state?

Animals, plants, fungi, and other microorganisms have always interacted and will continue to interact in diverse manners. However, they are influenced by abiotic factors and the complex impact of humanity in the developing Anthropocene. Our assumption is that science has the tools and methods to perform detailed quantitative studies that provide numbers for normal as well as extreme conditions.

Our long-term goal is to describe seemingly different interactions with the same tools and comparable ontologies and to combine them in a larger network that not only describes complex biological systems but reaches out to and interfaces with economic and political systems

Project Description

Aquatic ecosystems are among the most severely impacted ecosystem with excessive biodiversity loss. In particular, overexploitation, chemical pollution, fragmentation, habitat destruction or degradation and invasion by non-native species are the factors that can result in species loss.

Therefore, a comprehensive understanding of these factors and the robustness and resilience of aquatic systems is key to developing integrative concepts in aquatic ecology, nature conservation, and water policy. This understanding will be achieved in the research focus „Water“ via a multiscale approach (from the molecule to the ecosystem) and an interdisciplinary and transdisciplinary perspective.

Project Description

Global environmental problems do not only affect ecosystems, but also have consequences at the social and economic level. Due to the complex nature of these problems, estimating the interdependencies of effects is difficult and involves a high degree of uncertainty. For the management of global environmental risks, disciplinary approaches considering only partial aspects are not sufficient. In the research area, global environmental problems are therefore interdisciplinary analyzed using systemic approaches.

The research area "Systemic Risks" examines global environmental problems from a social-ecological and social science perspective. On the one hand, societal drivers of global environmental change are examined. On the other hand, concepts for interdisciplinary assessment of environmental risks as well as levers for sustainable transformation of nature-society systems on different levels are addressed.
