Table 1 Muscle and liver enzyme activity, fatty acid transport protein mRNA expression, and PPAR mRNA expression in yellow-rumped warblers maintained on a diet with 0.0 ppm (control) or 0.5 ppm (exposed) methylmercury for 14 d. Enzyme activity (μmol min−1 g−1) and expression (− ΔCT) values are means ± SE, and test statistics are from final general linear models.
