MicroBEEs: Consequences of land-use for solitary bee microbiota and function

When addressing land-use effects on plant-pollinator interaction networks, a major player has so far been largely ignored: Microbes. In MicroBEEs, we investigate how land-use induced changes in flowering plant composition and diversity affect bee-microbe interactions via changes in the species and nutritional composition of available floral resources. We combine network analyses of bee-plant (resource) and bee-microbe interactions with DNA-meta barcoding, shotgun metagenomics, laboratory assays and nutritional analyses. Our aim is to better understand which functions underlie interactions among and between mutualistic bee-microbe networks at both gene and taxonomic level. Specifically, we want to 1) disentangle bee-microbe networks in relation to land-use intensity and corresponding plant-bee diversity and network complexity, 2) define major functional genes of the bee microbiome, 3) experimentally verify the functional role of selected bacteria, and 4) assess how resource diversity and composition (and thus land-use intensity) affect the functional/taxonomic stability of (mutualistic) interaction.
