Levels of aggression and circulating steroid hormones were monitored simultaneously in free-living male lizards following a staged territorial aggressive encounter with another male. In the first 15 min following the aggressive encounter, the frequency of territorial patroling and the frequency of agonistic and advertisement displays increased four- to fivefold in resident males. In most cases these increases persisted for at least 90 min after withdrawal of the intruder male and probably persisted for the entire day of the encounter. Blood samples collected at 15-min intervals revealed no changes in circulating levels of testosterone or corticosterone while this behavioral change was occurring. Thus, the increase in aggressive behavior that follows a male-male territorial encounter in this species does not appear to be mediated by simultaneous changes in circulating levels of these hormones. Interspecific comparisons suggest that interspecific variation in steroid hormone involvement in rapid aggressive responses may depend on the mating system and the extent of male parental care.
在自由生活的雄性蜥蜴与另一只雄性蜥蜴进行模拟领地攻击遭遇后，同时监测其攻击水平和循环类固醇激素水平。在攻击遭遇后的前15分钟内，领地巡逻频率以及争斗和炫耀展示频率在领地占有雄性蜥蜴中增加了四到五倍。在大多数情况下，这些增加在入侵雄性蜥蜴撤离后至少持续90分钟，并且可能在遭遇的一整天都持续存在。在这种行为变化发生时，每隔15分钟采集的血样显示睾酮或皮质酮的循环水平没有变化。因此，该物种中雄性间领地遭遇后攻击行为的增加似乎不是由这些激素循环水平的同时变化介导的。种间比较表明，类固醇激素参与快速攻击反应的种间差异可能取决于交配系统和雄性亲代抚育的程度。
