Figure 2.

Relationships between litter size and oxidative damage (n = 18 in both cases). (a) Pre-reproductive oxidative damage (d-ROMs) in relation to litter size at birth (p = 0.039), (b) Post-reproductive oxidative damage (d-ROMs) in relation to litter size at weaning (p = 0.006). Unsuccessful females are not represented here because they either did not reproduce or they may have failed early in reproduction for other reasons than initial elevated oxidative stress levels. Notice that overlapping values are reducing to 16 the number of readily apparent points.
