Only thing I can think of off the top of my head is that the temperature is linked to food availability, when food is available its fine to make a bunch of females since their off spring wont have to compete for food, but if food is scarce then its better to make males, the ones best suited for survival will end up getting to mate, so its as if nature is using the food scarcity as a filter to get rid of bad genes

Other way around. Mothers are more likely to have daughters when the food supply is low. Females are hardier, are more resistant to famine and disease, and live longer. Mothers are more likely to have sons when they are living in plenty, because sons are less likely to survive childhood and require greater resources to grow taller and stronger.
