Subproject 4

The Research Unit MultiTroph is part of the Biodiversity-Ecosystem Functioning China (BEF-China) research platform. The platform was established in 2008 by Chinese, German and Swiss researchers and comprises the worldwide largest tree diversity experiment. MultiTroph aims to identify mechanisms underlying the relationships between biodiversity and ecosystem functions across different trophic interactions along the experimental tree diversity gradient of BEF-China. The ultimate goal is to connect the different interaction types to large food webs in the context of tree diversity loss.

In Subproject 4 we will generate and analyze interaction networks of cavity-nesting bees and wasps including their food resources and natural enemies using DNA barcoding and metabarcoding approaches. We will use reed nests and layer nests to continue our long-term monitoring of trophic networks with direct feeding observations. Furthermore, we will build up a reliable DNA barcoding approach, that serves as the basis to establish high-resolution metabarcoding of cavity-nesting Hymenoptera food webs.
