Fig. 2. Variation in (A) hemoglobin concentration and (B) red blood cell (RBC) number across the reproductive cycle on a high-quality diet (different lowercase letters indicate significant differences in means at P<0.05 using Tukey–Kramer adjustment); and variation in (C) hemoglobin and (D) red blood cell number across the egg-laying cycle on a high-quality (filled circles) versus low-quality (open circles) diet. Values are least-square means ± s.e.m.
