Substrate color selection. (a) Schematic diagram of the choice experiment used to test whether melanic and nonmelanic Phrynocephalus versicolor adults are behaviorally segregated according to their color. This area is divided into two type of substrates: where black surface indicates black substrate (left), and white surface represents weathered yellow substrate (right), and lizards were released at the boundary of two substrates (pointed by the arrow). See text for details. (b) Differences of lizards counting between black substrate and weathered yellow substrate for melanic or nonmelanic lizards. Statistics are presented as mean ± SEM. *Significant difference (p < .05) reported for corresponding color measuring point. ns, not significant
