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.

Lake habitats are disappearing as the climate changes

Global warming is increasing the surface temperatures of lakes worldwide – are species finding the temperatures they need to survive? Researchers led by IGB have quantified the long-term temperature changes in 139 lakes worldwide.

Ideas and perspectives: Biogeochemistry – some key foci for the future

Thomas S. Bianchi; Madhur Anand; Chris T. Bauch; Donald E. Canfield; Luc De Meester; Katja Fennel; Peter M. Groffman; Michael L. Pace; Mak Saito; Myrna J. Simpson

In order to empower the field of biogeochemistry further in its capacity to inform and influence social transitions, the authors make a strong plea to further strengthen the integrative nature of biogeochemistry. They put special attention to the integration of mechanisms, including both the molecular and eco-evolutionary perspectives, and insights from the social sciences.

Variation of bacterial communities along the vertical gradient in Lake Issyk Kul, Kyrgyzstan

Keilor Rojas-Jimenez; Alex Araya-Lobo; Fabio Quesada-Perez; Johana Akerman-Sanchez; Brayan Delgado-Duran; Lars Ganzert; Peter O. Zavialov; Salmor Alymkulov; Georgiy Kirillin; Hans-Peter Grossart

Diversity and community composition of bacteria along vertical gradients were studied in Lake Issyk Kul, Kyrgyzstan, the 6th deepest lake worldwide and the largest high-altitude lake. In the molecular assessment, the 16S rRNA gene analysis revealed significant changes in the composition, responding mainly to depth and salinity with Planctomycetes and Chloroflexi dominating in the deepest layers.

A review of hydropower plants in Romania: distribution, current knowledge, and their effects on fish in headwater streams

Gabriela Costea; Martin T. Pusch; Doru Bănăduc; Diana Cosmoiu; Angela Curtean-Bănăduc

Hydropower is renewable, but mostly not environmentally friendly. The study shows for Romania how the expansion of hydropower runs counter to the goals of EU environmental policy. Hydropower conflicts with the requirements of the Flora-Fauna-Habitat Directive and the European Water Framework Directive: around half of the hydropower plants in Romania are located in nature conservation areas.

Incomplete recovery of a shallow lake from a natural browning event

Garabet Kazanjian; Soren Brothers; Jan Köhler; Sabine Hilt

The authors investigated the recovery of a small, temperate shallow lake from a strong flooding-induced browning and nutrient loading event. Concentrations of dissolved organic carbon and phosphorus remained elevated and affected primary production despite water levels dropping to pre-flood levels indicating consequences of extreme precipitation for lake water quality and aquatic food webs.

Exploring the suitability of ecosystem metabolomes to assess imprints of brownification and nutrient enrichment on lakes

Jeremy A. Fonvielle; Darren P. Giling; Thorsten Dittmar; Stella A. Berger; Jens C. Nejstgaard; Anne Lyche Solheim; Mark O. Gessner; Hans‐Peter Grossart; Gabriel Singer

In the Lake Stechlin Lake Lab facility, the researchers tested whether dissolved molecules retain information about past and present alterations of lakes. They found that UV or microbial activities left measurable imprints on dissolved compounds, emphasising the relevance of the "ecosystem metabolome" to monitor the functioning and quality of lakes.
