Figure 4:

Immune reactive cortisol (black dots and solid lines) and corticosterone (black dots) across the full length of baleen plates from two calves with extensive cutaneous wounding from Kelp Gulls: (A) SRW female calf ‘091109PV-Ea45’ and (B) SRW calf of unknown sex ‘091208PV-Ea49’. The Y-axis is centred at the ‘natal notch’ (zero on the X axis) indicating the time of birth. X-axis indicates cm above the natal notch, i.e. positive values along the X-axis denote post-natal baleen growth while negative values indicate pre-natal growth. Arrows indicate ‘knolls’, regions with relatively higher elevations in glucocorticoids which could be associated with maternal GCs for the late pregnancy stages. In figure legend, B = corticosterone and F = cortisol.
