Dose-response curves for Snodgrassella relative abundance in the guts of honey bees after treatment with different concentrations of glyphosate. (A) One-day-old adult worker bees at the stage of acquiring the microbiota were treated with glyphosate for 20 days (early exposure). (B) Five-day-old bees with established gut microbial communities were treated with glyphosate for 15 days (late exposure). Dots show Snodgrassella 16S rRNA copy numbers in the guts of sampled bees. For both panels, four-parameter log-logistic dose-response models were fitted using the functions drm and LL.4 (to fit and define the structure of the regression model) in the package drc (58) in R v3.5.2 (56) (Table S2).
