Concentrations of faecal androgen metabolites in sexually mature meerkats largely reproduce patterns observed for concentrations of serum androgens: dominant females (red) and animals during reproductive events (hatched bars) have greater concentrations than do either subordinate females (pink), dominant males (dark blue), and subordinate males (light blue) or animals outside of reproductive events (solid bars), respectively.

Shown are mean + SEM logged concentrations of faecal androgen metabolites (ng/g) by (a) baseline sex (solid bars) and social status for both sexes, (b) male baseline values (solid bars) in relation to roving (hatched bars) and (c) female baseline values (solid bars) in relation to pregnancy (hatched bars). Numbers of individuals are included for each category in the bottom of the bar graphs. ***P < 0.001, **P < 0.01 and *P < 0.05.
