In the first project year we study species diversity as well as the impact of single and multiple stressors at the famous Breitenbach in Hesse (Germany). The Breitenbach has been studied by researchers of the Max Planck Institute for Limnology, River Station Schlitz, for about 40 years. Researchers of the institute have yielded unprecedented insights into the ecological principles of freshwater ecosystems, from bacteria to higher animals such as the insects (see Wagner et al. 2011 for an overview).

With support of the researchers and technicians of the former Max Planck Institute we have recommissioned on of the large emergence traps and also installed two mobile emergence traps. With both we collect data on species diversity and emergence dynamics. These data are of primary importance as part of the German Barcode of Life Projekt.
