Footprints (Contributing project)
Chemical signatures of resource competition between honeybees and wild bees along a landuse gradient
- Detect honeybee-induced shifts in flower visitation of bumblebees
- Evaluate the effect of land use intensity on competition between honeybees on bumblebees
- Measure fitness consequences for bumblebees
- Extract footprints from flowers
- Run GC/MS analysis
- Quantify resource overlap (H2’)
- Use landuse intensity (Li) and landscape context as predictor variables in an analysis of floral resource overlap
- Measure worker size across EPs
- Measure colony growth and reproductive output in a field experiment in the Schwäbische Alb
