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.

Fishing promotes small, shy fish

Fishing primarily removes larger and more active fish from populations. It thus acts as a selection factor that favours shy fish, as a recent study by IGB shows.

Defeating the enemy within

According to scientific theories, clonal vertebrates actually have a harder time succeeding than species that reproduce sexually. The Amazon molly proves otherwise. It has found a way to deal with the challenges of its origin and reproduction.

Depth-discrete metagenomics reveals the roles of microbes in biogeochemical cycling in the tropical freshwater Lake Tanganyika

Patricia Q. Tran; Samantha C. Bachand; Peter B. McIntyre; Benjamin M. Kraemer; Yvonne Vadeboncoeur; Ismael A. Kimirei; Rashid Tamatamah; Katherine D. McMahon; Karthik Anantharaman

The authors profiled the microbial community in Lake Tanganyika down to a kilometer deep and investigated their role in biogeochemical cycling. The microbial community in the surface waters was not all that different from a temperate lake, the anoxic water contained high abundances of Archaea (30%) and uncultured candidate phyla with high genomic capacity for nitrogen and sulfur cycling.

Adamescu; Sonja C. Jähnig

The year 2020 marked the end of the "UN Decade of Biodiversity". However, the final UN report showed that none of the 20 Aichi-Biodiversity Targets, agreed in 2010, have been achieved. Recognizing the perilous state of freshwater biodiversity, a research team led by IGB has issued 14 recommendations for political follow-up agreements on the protection of biological diversity.

Shallow lakes at risk: nutrient enrichment enhances top‐down control of macrophytes by invasive herbivorous snails

Ying Liu; Liang He; Sabine Hilt; Rui Wang; Huan Zhang; Gang Ge

The authors investigated how changing nutrient loading modifies the top‐down effect of one of the worst invasive herbivorous snail species on native submerged macrophytes.The results indicate that snail herbivory may increase the chance for macrophyte collapse and shifts of shallow lakes to turbid states, and that this effect occurs at lower snail densities when nutrient concentrations increase.

Shifting states, shifting services: linking regime shifts to changes in ecosystem services of shallow lakes

Annette B. G. Janssen; Sabine Hilt; Sarian Kosten; Jeroen J. M. de Klein; Hans W. Paerl; Dedmer B. Van de Waal

The authors identified major shallow lake ecosystem services and their links to Sustainable Development Goals (SDGs), compared service provisioning among the four ecosystem states and discussed potential trade-offs. They identified 39 ecosystem services which are linked to 10 different SDGs, while several trade-offs within and between ecosystem services across ecosystems were identified.

Projecting the continental accumulation of alien species through to 2050

Hanno Seebens; Sven Bacher; Tim M. Blackburn; César Capinha; Wayne Dawson; Stefan Dullinger; Piero Genovesi; Philip E. Hulme; Mark van Kleunen; Ingolf Kühn; Jonathan M. Jeschke; Bernd Lenzner; Andrew M. Liebhold; Zarah Pattison; Jan Pergl; Petr Pyšek; Marten Winter; Franz Essl

An international team including Jonathan Jeschke provide the first global quantitative projections of future trajectories of alien species numbers. Based on a new model and assuming a business-as-usual scenario, they project that the number of alien species will increase by 36% until 2050 worldwide and by 64% in Europe.
