Projects

since 2015     Enhancing biodiversity-based ecosystem services to crops through optimized densities of green infrastructure in agricultural landscapes ECODEAL (Biodiversa/BMBF)

Project summary:
Ecological intensification relies on ecosystem services to substitute external inputs in agriculture and has been proposed as a way to achieve high yielding, stable and sustainable crop production, while allowing to reach other societal targets such as nature conservation or human health. Pollination and natural pest control are key ecosystem services that can reduce pesticide use and increase crop yield quantity and quality. Organisms delivering these services depend to a large extent on non-crop habitats, or "green infrastructure" in the landscape, as cropland is not well suited as a habitat all year round. The project aims to answer the following questions: How much green infrastructure do we need to maintain stable communities of ecosystem service providers, and a high flow and stability of the services to the crop? Which type or combination of green infrastructure, old or young flower areas, arable fallows, seminatural grasslands, optimizes farmland biodiversity and ecosystem services? Since establishing non-crop habitat comes at a cost, which densities of green infrastructure will enhance crop yield and populations of service (or conservation) relevant species while providing net increases in crop productivity as well as net economic benefits to the farmer? ECODEAL will answer these questions.

Species groups: agricultural pests, pest control-related organisms incl. birds, pollinators

Study regions: Würzburg (Germany) and other European countries

Habitat: Agroecosystems

Methods: applied landscape ecology, GIS, yield measurements in crop fields, exclosure experiments for biocontrol and pollination assessment, biodiversity monitoring and sampling, greenhouse experiments

since 2013     Collaborative Research Center "Insect timing" (Sonderforschungsbereich SFB 1047)
Within the Collaborative Research Center "Insect timing", my group focuses on timing in plant-pollinator interactions. A mismatch in timing of mutualistic interaction partners might result in the disruption of such interaction, and potentially endangers the fitness of the partners. So far, it has been rarely studied  how changes in temperature, e.g. caused by anthropogenic climate change, shift the timing and fitness of interacting species. The central questions of this project are:

- How does ambient temperature affect the timing of the larval development and the emergence of pollinators?

- Does temperature synchronize the activity period of pollinators to the flowering period of their food plants, and can temporal mismatches be counteracted by bet-hedging strategies or by phenological plasticity, which might allow the re-adjustment of activity times in accordance to the timing of the partner?

- Can negative effects of mismatches be buffered by other (previously unimportant) species of the same functional group?
