Fig. 5. Body composition of controls (filled symbols) and diet-restricted nestlings (open symbols) of European shags. The relationship of lipid mass (A), liver mass (B), pectoral muscle mass (C), heart mass (D), leg muscle mass (E) and intestine mass (F) to body mass. The axes are log-scaled, and the linear regression lines are shown for each treatment group. Organ and body masses are lean dry (Ld) masses in g, and lipid mass is dry mass in g.
