Abstract: Sexual differentiation of green sea turtles is directed by incubation temperature. The constant incubation temperature that produces both sexes is known as the pivotal temperature, with warmer temperature producing more or all females and cooler temperatures producing more or all males. Here we present data on a laboratory experiment designed to evaluate the pivotal temperature of green turtles from Suriname. The best estimates for the pivotal temperature were 29.4 or 29.5 °C. These values are similar to a previous estimate of pivotal temperature from this green turtle population. When both datasets are combined, the pivotal temperature is estimated to be 29.2 or 29.3 °C. These values are within the range of limited information available from other green turtle populations. Nevertheless, more data from pivotal temperature experiments are needed for a greater understanding of how incubation temperature impacts local nesting populations.
