Fig. 2 Pregnancy rates of female white-tailed deer (Odocoileus virginianus) in northern Illinois with corresponding litter sizes represented as a proportion of pregnant females by age class. Panel A: vertical reference line indicates 31 days; fawn n = 1,494, yearling n = 736, adult n = 2836. Panel B: fawn n = 233, yearling n = 444, adult n = 1924.

Fig. 3 Growth curves by fetal sex for white-tailed deer (Odocoileus virginianus) fetuses collected in northern Illinois. Curves fit to the data using Gompertz growth regression in SigmaPlot v. 13. Drop lines from regression correspond to pictured fetal sizes. Data used to generate plot include 2333 male fetuses and 2256 female fetuses.

Fig. 4 Effect of maternal age and litter size (fetus number) on fetal size of white-tailed deer (Odocoileus virginianus) from northern Illinois. Graph represents the group means of fetal BMI by maternal age class. Error bars depict the standard error of the means. Table below figure panel presents the significance levels for group comparisons (*** < 0.001, ** < 0.01, * <0.05, NS not significant). Sample sizes include 3595 fetuses of adult females, 749 fetuses of yearlings, and 241 fetuses of fawns.
