   Notes: Significance is indicated by bold. Superscripts indicate the source term used as the error term for the F tests. ANOVA results for (A) size at first offspring, (B) for age at first reproduction, and ANCOVA results for (C) total offspring production and (D) reproductive rate. Time spent reproducing was a covariate for total offspring production; age at death was a covariate for reproductive rate.
