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.

New insights for species conservation

Using water fleas, Luc De Meester showed that a population with a high amount of genetic variation can quickly adapt its behavioural and life-history traits to changes in the environment.

Fulvic acid accelerates hatching and stimulates antioxidative protection and the innate immune response in zebrafish larvae

Thora Lieke; Christian E.W. Steinberg; Sandra Bittmann; Sascha Behrens; Seyed H. Hoseinifar; Thomas Meinelt; Klaus Knopf; Werner Kloas

Improving growth and health parameters by immunostimulants is widely used in older fish, but rarely studied in larvae. Using zebrafish as a model organism, the authors evaluated the effects of exposure to fulvic acids (FAs) on embryonic development. They showed that FA at low to medium concentrations can increase the health of larvae, but becomes detrimental at higher concentrations.

Ice-covered lakes of Tibetan Plateau as solar heat collectors

Georgiy B. Kirillin; Tom Shatwell; Lijuan Wen

The authors investigated the thermal properties of Tibetan lakes during the ice-covered season. They revealed that an extremely large amount of solar radiation penetrated the highly transparent ice cover. As a result, lakes fully mix under ice and get heated up to >6°C. The accumulated heat makes a crucial contribution to ice cover melt.

Model-based decomposition of environmental, spatial and species-interaction effects on the community structure of common fish species in 772 European lakes

Thomas Mehner; Christine Argillier; Trygve Hesthagen; Kerstin Holmgren; Erik Jeppesen; Fiona Kelly; Teet Krause; Mikko Olin; Pietro Volta; Ian J. Winfield; Sandra Brucet

The authors compared the contribution of species interactions to forming fish communities in lakes, relative to effects from abiotic filtering and dispersal. Using Bayesian models with latent variables, they demonstrate that predator-prey and competitive interactions structure biomass and mean mass of fish communities, whereas abiotic filtering and dispersal shape their presence/absence structure.

Hessen; Scott N. Higgins; Klaus D. Jöhnk; Wendel Keller; Lesley B. Knoll; Peter R. Leavitt; Fabio Lepori; Martin S. Luger; Stephen C. Maberly; Dörthe C. Müller-Navarra; Andrew M. Paterson; Donald C. Pierson; David C. Richardson; Michela Rogora; James A. Rusak; Steven Sadro; Nico Salmaso; Martin Schmid; Eugene A. Silow; Ruben Sommaruga; Julio A. A. Stelzer; Dietmar Straile; Wim Thiery; Maxim A. Timofeyev; Piet Verburg; Gesa A. Weyhenmeyer; Rita Adrian

The authors have quantified the long-term temperature changes in 139 lakes worldwide. They analysed shifts in thermal habitats and found that as lakes warm, species will need to shift to different depths or seasons. Lakes in the tropics are particularly affected.

Viewing emerging human infectious epidemics through the lens of invasion biology

Montserrat Vilà; Alison M. Dunn; Franz Essl; Elena Gómez-Dìaz; Philip E. Hulme; Jonathan M. Jeschke; Martìn A. Núñez; Richard S. Ostfeld; Aníbal Pauchard; Anthony Ricciardi; Belinda Gallardo

A research team has studied the close relationships between infectious diseases and biological invasions. The "One Health" approach considers the health of humans as well as animals, plants and other elements of the environment to prevent pandemics and the spread of invasive alien species.
