Figure 3.

Hydric physiology of G. sila differed across measurement periods throughout their active season and based on lizard sex. Hydric physiology was measured as CEWL (a), plasma osmolality (b) and body condition (c; Peig and Green, 2009). Large points with error bars represent model-estimated means ±95% confidence intervals. Each small point represents a measurement on an individual lizard. Sample sizes are noted on the x-axis. Different letters denote significant pairwise differences between measurement periods for a given sex (P < 0.0001 for females; P < 0.04 for males), and asterisks denote significant pairwise differences between sexes for a given measurement period (P < 0.04), based on that linear mixed-effects model (Table 2). These means are on the full dataset from our study, which includes 1–3 measurements on any given lizard; means based only on data from lizards with 2–3 repeat measurements showed the same patterns.
