The main objective of my PhD is to understand species-specific differences in foraging patterns and resource intake of stingless bee colonies in a tropical ecosystem in Ecuador and Costa Rica. My specific objectives are:
1. Explore the species richness of floral sources visited (pollen and resin via DNA-metabarcoding) and resource intake (i.e. foraging activity, protein content of collected pollen, sugar concentration in collected nectar) of different stingless bee nests.
2. Explore species-specific nutritional preferences (protein and lipid content in pollen, sugar concentration in nectar), floral and resin sources visited by different stingless bees, as well as changes in bee-plant networks over the course of the day.
3. Explore preferences of stingless bees with regard to nectar chemistry using feeding choice and cafeteria experiments.
4. Improve a protocol to extract and quantify fatty acids in pollen samples.
