Study ID	ST003553
Study Title	Investigation of age-dependent changes in the gut of honeybee workers using targeted metabolomics for amino acid and biogenic amine determination
Study Summary	In the honeybee guts we measured the concentrations of 20 amino acids and 6 biogenic amines. Tryptophan and its downstream metabolite kynurenine followed the same trends across the worker development, with a significant decrease in their concentrations from day 3 onwards. Serotonin, on the other hand, was significantly increased from day 1. Tyramine and octopamine showed significant increases in concentrations (octopamine for all age groups apart from Day 1; tyramine for all age groups), while their precursor tyrosine showed significantly decreased concentrations for all age groups except experienced foragers.

Treatment:

Treatment ID:	TR003691
Treatment Summary:	On the day of newly emerged workers (day 0), bees were samples as a baseline for no or low bacterial abundance in the gut. Moreover, bees from each hive were collected on Day 1, 3 and 5 to cover the establishment phase of the gut. Samples for the in-hive worker phase, defined as workers inside the hives that have a fully developed microbiome, were taken every day from Day 7 to Day 10. For the foraging phase, we differentiated between new and experienced foragers, as these show different behaviour due to different levels of experience.Based on experience, they were either collected one to two days after onset (new foragers) or at least four days after onset (experienced foragers).
