Fig. 3. (A,B, left) Growth rate vs initial snout–vent length (SVL) for individual males of (A) Sceloporus virgatus and (B) S. jarrovii, by treatment group. (A,B, right) Growth rate by treatment group, from data in left panels. Lowercase letters denote differences among treatments based on post hoc comparison of growth rates from (A) separate slopes or (B) ANCOVA models with initial SVL as the covariate. Values are means ± 1 S.E.M. (N values are given in bars). Regression equations: (A) CAST, y=–0.002x+0.235; CON, y=–0.013x+0.702; TEST, y=–0.004x+0.251; (B) CAST, y=–0.001x+ 0.113; CON, y=–0.008x+0.591; TEST, y=–0.005x+0.406.
