Overcoming the longstanding separation of individual research disciplines within biodiversity research is the goal of the joint Berlin-Brandenburg project ‘Bridging in Biodiversity Science’ (BIBS). The investigations of individual, often isolated research schemes slow down scientific progress and the development of effective measures for biodiversity. This project builds bridges between disciplines, scales and systems. Focusing on the challenge posed by rapid change in ecological systems, BIBS studies will focus on the often neglected interfaces between disciplines, as well as the value and limitations of the ‘bridge’ concept. The focus of the work packages is on the bridging element of research on marine-terrestrial systems, rural-urban gradients, ecosystem components on and below the surface, and natural versus novel ecosystems. The project will develop sound policy recommendations, and the whole chain of causes, mechanisms and consequences of change on different ecosystems and spatial-temporal scales wil be considered. The results will be presented as conceptual publications both to the scientific community and to policy makers and the general public. In addition, BIBS includes citizen science projects and science-social platforms for exchanges between the scientific community, government and society. As the DLR Project Management Agency, we have already – in the authorisation phase – enabled the integration of an active knowledge transfer interface between the German Centre for Integrative Biodiversity Research (iDiv) and BIBS, and initiated meaningful cooperation with the concurrently running Changing City Climate Joint Project ‘3DO’ that investigated Berlin, Hamburg and Stuttgart.
