a Data are calculated using mean egg size per clutch. Only data for those 

 clutches at, or earlier than, Harrison developmental stage 30 are presented 

 (see text for explanation).

Fig. 2. Coefficients of variation (CV) of intraclutch variation in egg size 



for five species of salamanders. Number of clutches examined for each 



species is indicated. Vertical lines indicate means not significantly 



different using a model I ANOVA with species as treatment. (<x = 0.05).
