Signature 1
Source: Figure 4A
Description: Bacteria Taxa determined by ANCOM-BC to be differentially abundant in 2.3years old Assamese macaques (mean age -1SD, equivalent to infant age class) Versus 4.7years old Assamese macaques (mean age, equivalent to Juvenile age class), exposed to prenatal, maternal glucocorticoid during early pregnancy/gestation (Early-preGC), as assessed within the rich season.
Abundance in Group 1: increased abundance in Early pregnancy glucocorticoid (Early-preGC) exposure in 2.3years (mean age -1SD)

Description: Bacteria Taxa determined by ANCOM-BC to be differentially abundant in 2.3years old Assamese macaques (mean age -1SD, equivalent to infant age class) Versus 4.7years old Assamese macaques (mean age, equivalent to Juvenile age class), exposed to prenatal, maternal glucocorticoid during early pregnancy/gestation (Early-preGC), as assessed within the rich season.
Abundance in Group 1: decreased abundance in Early pregnancy glucocorticoid (Early-preGC) exposure in 2.3years (mean age -1SD)
