Figure 1.

Mean (± s.e.m., n = 8 otoliths) percent polymorph composition (i.e., aragonite, vaterite) by weight of sagittal and lapilli otoliths collected throughout the ontogenetic development (i.e., days post hatch, dph) of Lake Sturgeon, Acipenser fulvescens, and White Sturgeon, A. transmontanus. Stars (*) indicate significant differences between species at developmental stage (i.e., days post hatch; dph) while letters indicate results of post-hoc Tukey HSD tests where developmental stages not sharing the same letter are significantly different. Lapilli otoliths of Lake Sturgeon are not included at 12 and 14 dph because they were too small to remove. Note the measured values are proportions thus the error bars apply to both aragonite and vaterite.
