Circulating carotenoid titer as a function of age.

<p>Significant differences (<i>P</i><0.05) within developmental treatment are denoted by #, and within adult treatment by *. Each treatment group is labeled based on access to LOW or HIGH levels of carotenoids during development (2–49 days old; first word in legend) and LOW or HIGH levels at adulthood (119–137 days old; second word in legend). HIGH levels of carotenoids during the first 7 weeks of development increased circulating carotenoid titer by the end of development, but these differences disappeared by the beginning of the adult stage. HIGH levels during adulthood increased circulating carotenoid titer within one week, and levels remained relatively higher throughout the remainder of the study.
