We want to understand and protect the diversity of life on Earth by studying ecosystems, species interactions, and the drivers of biodiversity loss.
Our planet is exposed to severe anthropogenic pressures with profound impacts on the climate, global biogeochemical cycles, and ecosystems resulting in the reduction of natural habitats, loss of biodiversity, and critically altered environmental systems.
Within the focus area on biodiversity and ecosystems, our researchers develop a deeper understanding of these complex and interrelated environmental changes. To reach this goal, we are connecting expertise from all relevant areas—from natural to social scientists including specialists in environmental policy, law, and economics. This way, we are able to transcend disciplinary boundaries and develop integrated solutions to the pressing challenges posed by biodiversity loss.
Peatlands are powerful carbon sinks - if we let them stay intact. New research from ECH members shows how wetland farming - magic word: paludiculture - and microbial life can work together to reduce emissions without sacrificing land use. A story of science, sustainability, and the surprising appetite of microorganisms.
Beneath the surface of Croatia’s largest natural lake, a silent transformation is underway. In a new study, researchers from the University of Vienna and the Ruđer Bošković Institute reveal that climate change is salinising Lake Vrana - threatening freshwater ecosystems and amplifying global climate risks. What looks like a holiday paradise may be a warning sign.
The ocean stores many times more carbon than the atmosphere, yet many of the mechanisms behind its carbon cycles are not yet fully understood. For over three decades, Gerhard Herndl from the University of Vienna has been studying the microbial life in the deep sea and how it can help to explain where the carbon goes and how this influences the climate.
Franz Essl at the Department of Department of Botany and Biodiversity Research is leading the “AgriWeedClim” project.
Agriculture is affected by various factors, such as climate change, biological invasions, changing land use, and increasing intensification of land use. These factors also affect weed species.
Stephan Glatzel at the Department of Geography and Regional Research is leading the “PRINCESS” project.
The PRINCESS project investigates the potential role of rewetting drained, nitrogen-contaminated peatlands in reducing EU-wide greenhouse gas emissions, improving wetland biodiversity while minimizing socio-economic impacts on stakeholders.
Christian Griebler at the Department of Functional and Evolutionary Ecology is leading the “Heat below the City” project.
Groundwater is one of our most important and heavily utilized resources. However, it is also home to a variety of microbes and fauna.
Gerhard Herndl at the Department of Functional and Evolutionary Ecology is leading the “ECOTIP” project.
The Arctic marine environment is under rapid change, both in its physical and biotic conditions.
Lucia Fuchslueger at the Department of Microbiology and Ecosystem at the University of Vienna coordinates a research stream with the “AmazonFACE” project.
The Amazon Forest is a crucial carbon sink and controlling our global climate, and potentially off-setting much anthropogenically released CO2.
Alice Vadrot at the Department of Political Science is leading the “MARIPOLDATA” project.
MARIPOLDATA is an ERC Starting Grant project with a research team led by the Principal Investigator Assoc. Prof. Dr. Alice Vadrot, which develops and applies a new interdisciplinary and multi-scale approach to study new forms of power at the intersection between science and politics.
