How is biodiversity changing?
Biodiversity is declining dramatically worldwide. BGB is investigating how species diversity is changing in space and time - both locally, for example, in the Thur catchment area in Switzerland, and also globally with the help of data archives and satellite data. The time periods studied range from a few decades to millions of years.
What influences species diversity?
Land use changes, such as intensified agriculture and urbanisation, climate change, the overexploitation of natural resources and invasive species alter habitats and threaten biodiversity. BGB investigates how these factors influence biodiversity.
How are terrestrial and aquatic ecosystems interconnected?
Ecosystems in water and on land are closely linked. For example, leaves that fall from trees into water serve as food for microorganisms. These are eaten by predatory insect larvae that leave the water after their final larval stage. On land, these insects serve as particularly nutritious food for birds. BGB aims to study this networked biodiversity holistically.
How can we promote and protect biodiversity?
BGB aims to develop practical recommendations for praxis and policy to stop or at least reduce species loss as quickly as possible. How can habitats in residential areas be networked through blue-green infrastructure? Or, what does successful biodiversity policy look like?
