Figure 1. Generalized Additive Model (GAM) fits of air temperature (°C) against hatchling output at Playa Grande.
Smooth fits from GAMs show the additive effects of mean air temperature (°C) during the two months of incubation on mean monthly (a) hatching success and (b) emergence rate of leatherback turtle clutches at Playa Grande. Tick marks on the x-axis represents observed data points and Y-axis represents the smooth function and the values are centered. Gray area corresponds to two standard errors around the main effect.
