Relative expression of foraging mRNA in workers over time. Relative expression of foraging mRNA in individual worker brains from experimental colonies of P. occidentalis. Colonies were entrained in controlled environmental chambers in a 12:12 hr LD regime. Foragers (light bars, n = 4 colonies) and nest workers (dark bars, n = 4 colonies) were collected at six time points. Bars represent the averages of colony means with three nest workers and three foragers sampled per colony (SE calculated across colonies). The open stripe in the horizontal bar at base of the plot represents the light phase and the solid stripe represents the dark phase.
