Facilities and Equipment

The Institute has established a unique, innovative experimental infrastructure. IGB is continously improving and extending its laboratory equipment, in particular to support molecular, microbial, biogeochemical and phycological research to enable analytics in recent fields of research.

Large experimental research facilities

Studies on the biology of fish can be conducted in the aquarium (1,000 m² floor space) with fresh water recirculation systems in tanks of different sizes. Additionally, there are different open ponds available for these research. Further studies in aquaculture research are conducted in the Aquaponic- system, a greenhouse for the combined production of fish and vegetables (tomatoes).

 

In the stratified, eutrophic Lake Dagow, large enclosures were installed to study the effect of altered food webs on sediment activity.

 

Much larger mesocosms are currently installed in the oligotrophic Lake Stechlin, including the sediment-water and water-atmosphere interfaces. These enclosures will form the experimental backbone of the Lake Stechlin Research Centre to study climate-related impacts on the biodiversity of microbiota and related ecosystem functions (Project: TemBi).

 

IGB has divided whole lakes, including the “Große Fuchskuhle” for studying the impact of humic substances on the diversity and activity of bacteria, and the Lakes Gollin and Schulzen to simulate the effect of enhanced input of natural particulate carbon on the aquatic food web - from bacteria to fish (Project: TERRALAC).

 

The Hydro-Ecological Field Experimental Flume (HEFE) along the River Spree east of Berlin was finished in 2010. It allows to experimentally study the consequences of  hydrologic and hydraulic alterations on aquatic ecology and applied issues under natural field conditions. Flow rate and velocity can be manipulated in two 350 m long channels through an upstream artificial weir. This innovative facility especially serves to conduct interdisciplinary hydraulicecological projects.

 

In-situ behavioral ecology studies are conducted Lake Kleiner Dölln using the installed 3D telemetry system. Research questions tested here deal with the importance of personality for reproductive fitness of prey species in the field. Further research concerned with the elucidation of mechanisms of selection in terms of behavior characteristics in wild fish.

 

The installation of continuous logging environmental data on lakes Mueggel and Stechlin and the River Spree is a basic infrastructure of long-term research in the context of limnological basic research. In several research initiatives impacts of global climate change on aquatic system were studied.
