Note spherical orientation of embryo, even at late developmental stages. Bars = mm. Egg laying is not synchronous in plethodontid salamanders, and this precludes collection of a large number of plethodontid clutches at early stages of development. Therefore, I collected clutches at various stages of development. To ensure that intraclutch variation did not vary with development, a Wilcoxon's matched-pairs signed-ranks test was conducted on 12 D. santeetlah clutches to test if stage of development significantly influenced CV. Coefficients of variation were calculated for two developmental stages (stage 45 and an earlier stage, ranging from 9 to 41 for the clutches in question) for each clutch, and no significant difference was found in CV due.
