Research for the future of our freshwaters

 Our profile

Our vision is the understanding of processes that shape the structure and functioning of water bodies and their biota. Our research findings help to predict responses to environmental change and to develop measures conductive to sustainable water management.

IGB is Germany’s largest and one of the leading international research centres for freshwaters. Here, hydrologists, biogeochemists, physicists, microbiologists, evolutionary ecologists, fish ecologists and fisheries biologists from all over the world are working under one roof.

Hydropower: the mortality risk for fish at turbines

IGB has presented a procedure for the assessment of fish mortality at hydroelectric power plants. The researchers advise against subsidising small hydropower plants unless adequate fish protection is implemented.

We need a safety net for biodiversity

Not only species, but also their habitats and genetic diversity need ambitious, interlinked targets. The study in Science with Luc De Meester outlines the scientific basis for redesigning the new set of biodiversity goals.

IGB Annual Research Report 2019

This annual research report spotlights our research results on freshwater biodiversity, greenhouse gases in inland waters, water in the landscape, and protection and use of freshwaters, as well as the most important developments at IGB in 2019 – in short: one year of freshwater research.

Outlines | IGB Policy Brief: Strengths and weaknesses of the Water Framework Directive (WFD)

The IGB Policy Brief recommends continued commitment to the objectives of the WFD and improved practical implementation – and offers options for action to policy makers and practitioners.

Climate change destabilizes aquatic ecosystems through weakening the interactions between species richness and biomass of phytoplankton and the chemical and physical environmental factors. This is the conclusion of a study on long-term data series of 10 aquatic ecosystems using the convergent cross mapping (CCM) method.

The role of connectivity in the interplay between climate change and the spread of alien fish in a large Mediterranean river

Johannes Radinger; Emili García-Berthou

Dams exacerbate the consequences of climate change on river fish: A potential response of river fish to environmental changes is to colonise new habitats. Dams restrict the habitats of fish, but do not necessarily prevent the spread of invasive species, as Johannes Radinger and his team found.

Pragmatic animal welfare is independent of feelings

Robert Arlinghaus; Ian G. Cowx; Brian Key; Ben K. Diggles; Alexander Schwab; Steven J. Cooke; Anne Berit Skiftesvik; Howard I. Browman

In this Letter to Science the researchers argue that effective application of animal welfare in conservation is also possible if it is based on objective and measurable parameters of animal welfare – without relying on concepts such as consciousness, sentience or pain.

Species distribution models have limited spatial transferability for invasive species

Chunlong Liu; Christian Wolter; Weiwei Xian and Jonathan M. Jeschke

In this synthesis study, a research team led by IGB shows that species distribution models have limited spatial transferability for invasive species and how this relates to species characteristics and model parameterization.
