Fig. 4. Both the total respiration (A) and respiration during day 45 (B) were
greater for embryos from VA than they were for embryos from SC. Total
respiration was 1291±52 J and 1191±53 J for embryos from VA
(N=20) and SC (N=19), respectively. Respiration during day
45 was 1.71±0.13 J h–1 and 1.62±0.13 J
h–1 for embryos from VA (N=19) and SC
(N=19), respectively. Yolk manipulation did not affect the
respiration of embryos. Data were adjusted for embryonic growth or embryonic
mass by ANCOVA (see text for details). Error bars represent 95% confidence
intervals of means for each treatment.
