Curriculum vitae

Research interests

Impact of climate change, landscape composition and anthropogenic land-use changes on biodiversity, ecosystem functioning and ecosystem services with special focus on agroecosystems (in particular floral diversity and pollination)

Development and trial of strategies to conserve and increase biodiversity and ecosystem services in agroecosystems (sustainable and environmentally friendly farming practices in conventional and organic agriculture systems)

Significance of biodiversity and related ecosystem services for crop production and human well-being (especially quality of plant products)

Vegetation composition and dynamics (Central Europe)

Forest ecology

Urban ecology and urban agriculture
