This study addresses several basic questions relating to the roles of badges and displays in establishing social structure in male Phrynocephalus vlangalii. Significant differences in body mass and condition were found between resident and floater males of P. vlangalii, and resident males engaged in tail curling and agonistic interactions more frequently than floater males. Frequency of tail curling was correlated negatively with body mass in floater males, but was not correlated with body mass and condition in resident males. Relative tail-tip badge size, relative belly patch size and relative tail length could significantly predict an individual's body mass, and body condition was positively correlated with relative tail length, suggesting that resident males may establish their social dominance by communicating their body mass and condition through frequent tail curling.
