There was an error published in J. Exp. Biol.216, 452-459. The calculations of carbon fixation and translocation rates, which are presented in supplementary material Table S2, were incorrect. The error was not in the measured data (disintegrations per minute of radioactive samples), but a mathematical error that occurred when calculating the amount of carbon in the sample incubations. Thus, the error does not affect the percent carbon translocation values, only the calculated rates of carbon fixation and translocation per hour.

In Results, Carbon translocation (p. 455, lines 8–10), the text should read:>

The average hourly rate of carbon fixation was 589.1±56.7 ng carbon per sample, or 294.5 ng carbon per egg. An estimated average 15.4 ng fixed carbon was translocated to each egg per hour.

The correct version of Table S2 appears below:
