Fig. 1. Variation in (A) body mass and (B) hematocrit 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) body mass and (D) hematocrit 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.
