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<sup>−1</sup>), ‘WBC’ total leukocyte concentration (10<sup>9</sup> L<sup>−1</sup>) and ‘PHA’ response to phytohemagglutinin (mm). Note that the relationship shown in (B) is for females only.</p
The effects of changes in immune measures on changes in body condition for models of relationships that explained significantly more variation than equivalent null models (Table 1); see Tables S2–3 for full model details.
<p>‘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 <sup>−1</sup>), ‘WBC’ total leukocyte concentration (10<sup>9</sup> L<sup>−1</sup>) and ‘PHA’ response to phytohemagglutinin (mm). Juvenile sample sizes are shown as the total number of data points followed by the number of individuals.</p
Boxplot for number of Caspian seal carcases recorded monthly (1971–2008) in the 10 km Apsheron monitoring zone.
<p>Central line of boxes gives median carcases per month. Red line gives mean carcase number.</p

Boxplots of contaminant burdens by sex-age class (top) and CDV status (bottom).
<p>Red dashed line indicates proposed threshold for potential toxic effects for ∑TEQ levels (196−220 pg/g lipid weight) derived from experimental studies in harbour seals (De Swart et al. 1994, 1995a, 1995b, 1996, Ross et al. 1995). y axis is plotted on log10 scale.</p
