Climate change in a landscape context: functional biodiversity, biotic ecosystem services and data synthesis
Climate change and the increased occurrence of extreme climatic events, together with land use changes, are considered as the main causes for the decline of insects. As pollinators and antagonist of herbivorous insects, they ensure essential ecological services. In nature conservation, insects are an important target group due to their high biodiversity and diverse life history traits. However, there is currently a lack of basic knowledge about the effects of climate change in Bavaria on the distribution, biodiversity and biotic interactions of insects and how intensive land use may reinforce them.

Subproject 1 covers the biodiversity of bees, wasps, hoverflies and beetles as well as the ecosystem services of pollination and biological pest control in the joined experimental design of the LandKlif network in near-natural, agricultural and urban habitats. In addition, dislocation experiments and simulations of extreme climatic events are carried out in order to better understand the adaption potential or the resilience of functionally important insect groups. The results deliver the basis for a more sustainable management of Bavaria ecosystems and thus make an important contribution to the preservation of insect diversity and its ecological services in the context of climate change.
