Latitudinal Variation in the Pattern of Temperature-Dependent Sex Determination in the Japanese Gecko, Gekko japonicus.

Discussion Our study demonstrated that the low (24 °C) and high (32 °C) incubation temperatures yielded significantly female-biased hatchlings, while the medium temperatures (around 28 °C) produced male-biased hatchlings or an even sex ratio of hatchlings in I G. japonicus i .

The dataset provided daily mean air temperatures, daily maximum air temperatures, and daily minimum air temperatures of 30-year means: (a) mean air temperature; (b) maximum air temperature; (c) minimum air temperature. In our species, maternally derived yolk steroid hormones interact with incubation temperatures to affect offspring sex ratio, with substantial effects of yolk hormones on offspring sex ratio at the medium temperature of 28 °C [[14]].
