Sex ratios (a-c) and sex differences in maturation age (d) and adult mortality (e) in GSD and TSD reptiles. Sex ratios are given as the proportion of males, thus 0.5 represents an even sex ratio. For maturation age and adult mortality, positive values refer to later-maturing females and higher female mortality, respectively. In each box plot, each data point represents one population; the thick middle line, box, and whiskers show the median, interquartile range, and data range within 1.5 × interquartile range from the lower and upper quartiles, respectively. Numbers below each box denote the number of species (number of populations in brackets)
