A. Relative AIC over different development windows, using TSD model type FM logistic. The period 0.50–0.55 has the lowest AIC (relative AIC set to zero). Generally development windows including 0.50–0.55 have low AIC. B. Example showing the relationship between the CTE (0.50–0.55) in natural nests and the hatchling sex ratio. The curve (—) is the maximum likelihood fit, and dashed lines are ± 2 SE.
