Predicted relationships between changes in immune measures and changes in body condition in Galapagos sea lion pups resident in the human-impacted (A, C, E) and the control (B, D, F) colonies.

<p>Dotted lines represent 95% confidence intervals, ‘Δ’ denotes ‘change in’, ‘MLR’ mass per unit length (kg), ‘SFT’ skinfold thickness (cm), ‘ALB’ albumin concentration (relative peak intensity), ‘IgG’ total immunoglobulin G concentration (mg mL⁻¹), ‘WBC’ total leukocyte concentration (10⁹ L⁻¹) and ‘PHA’ response to phytohemagglutinin (mm). Note that the relationship shown in (B) is for females only.
