Few studies have examined the role of steroid hormones in mediating tactic-associated differences in male agonistic behaviour. Long-term (24 h) steroid hormone responses to winning staged male–male encounters in different morphs of free-living male tree lizards,Urosaurus ornatus, were studied. Males belong to either an aggressive, territorial (type) morph or to a less aggressive, non-territorial morph. On the day after winning a staged male–male encounter, males of the less aggressive morph… 

Steroid Correlates of Territorial Behavior in Male Jacky Dragons, Amphibolurus muricatus

Results suggest that high circulating T is acting in a preparatory manner to increase the likelihood of producing a territorial response upon engaging in a social encounter, however, once this response has been initiated T may not need to remain elevated to allow continued expression of territorial behavior.

Social competition, corticosterone and survival in female lizard morphs

Results are consistent with decreased fitness effects and suppression of immune function previously reported for orange female morphs surrounded by more orange neighbours, and indicate that corticosterone is likely to be an important physiological mechanism regulating female fitness in nature.

The evolution of colour polymorphism in the painted dragon, Ctenophorus pictus

It is demonstrated that red- headed males beat yellow-headed males in staged contests for females and that this is linked to what appears to be a convention of red dominance in male-male interactions set very early in ontogeny, long before colouration has developed.

Hormonal response of male green anole lizards (Anolis carolinensis) to GnRH challenge.

GnRH challenges on lightweight and heavyweight males to determine if lightweight males were capable of producing comparable levels of circulating testosterone to heavyweight males but are socially or physiologically suppressed from doing so failed, suggesting more field studies are needed in reptilian systems.

Seasonal Specificity of Hormonal, Behavioral, and Coloration Responses to Within- and Between-Sex Encounters in Male Lizards (Sceloporus undulatus)

The biological significance of hormonal, behavioral, and coloration responses of resident male S. undulatus in social interactions with conspecifics are clarified in terms of potentially aggressive versus courtship interactions and breeding versus postbreeding contexts.
