Fig. 1.

Box plot diagrams of A: snout-vent length and B: body mass (note log2 scale) for dissected animals grouped by age and sex (open boxes = female; grey boxes = male). Boxes define 75^th to 25^th percentiles and are bisected by the mean values. Whiskers define 90^th and 10^th percentiles with outliers (filled circles) above and below. Superscripts over boxes denote differences between groups (P > 0.05). Sample sizes for each group are set below graphs. C: A scatterplot diagram of snout-vent length and body mass for laboratory-raised animals (open figures) and field-captured, Lake Woodruff juvenile animals (solid figures). Males = triangles; females = circles. Individual locally weighted scatter plot smoother (LOWESS) curves (tension = 50) are plotted for each group.
