FIG. 1.

Body morphometrics measurements from 13-mo-old alligators. Incubation periods were 30 or 33.5°C (A, C, E, G, and I) and 32°C (B, D, F, H, and J). Crosshatched bars are Lake Apopka females (F), and black bars are Lake Woodruff females. Diagonal lined bars are Lake Apopka males (M), and white bars are Lake Woodruff males. Bars represent the mean ± SEM for body mass (A and B), snout-vent length (C and D), and total length (E and F). Condition indices (body mass/length measurement³) were calculated using either snout-vent length (SVL; G and H) or total length (TL; I and J). In J, an uppercase A and B over bars denotes a significant sex effect; in B, D, F, and J, a lowercase x and y over bars denotes a significant lake-of-origin effect.
