Figure 1: Geography and egg size of sampled populations. (A) Map showing the geographic range of the American alligator and sampled populations. (B) Egg mass variation across populations.
Figure 2: Population variation in the influence of egg mass and temperature on morphological traits, showing (A) the relationship between egg mass and hatchling mass, (B) hatchling mass and (C) snout-vent-length (SVL). In (B) and (C), plotted values are model means under a common egg mass (83g). Error bars represent 95% confidence intervals.
Figure 3: Population variation in metabolic traits and the influence of incubation temperature, showing (A) fat body mass, (B) residual yolk mass, (C) mass-specific fat body mass, and (D) mass-specific residual yolk mass. Error bars represent 95% confidence intervals.
Figure 4: Population variation in the influence of incubation temperature on incubation duration. Error bars represent 95% confidence intervals.
