Female anoles display less but attack more quickly than males in response to territorial intrusions

Female brown anole lizards, which are smaller and often thought of as less aggressive than males, attack same-sex intruders more quickly, consistent with the idea that fighting may be risky for males because of their stronger jaws.

Do displays and badges function in establishing the social structure of male toad-headed lizards, Phrynocephalus vlangalii?

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 taillength, suggesting that resident males may establish their social dominance by communicating their body mass and condition through frequent tail curling.

Deferred agonistic behavior in a long-lived scincid lizard Eumeces laticeps

In the laboratory, males in their home cages were significantly more likely to win encounters with males of similar size than were males fighting in the home cages of opponents, suggesting that encounter site could be important in determining encounter outcome and that field study of possible site defense or territoriality is needed.

A Quantitative Study of the Social Behavior of Tree Lizards, Urosaurus ornatus

Nine adult tree lizards, Urosaurus ornatus, were maintained in a large, indoor enclosure, and each individual was monitored simultaneously, and a despotic hierarchy was established.

Offenders tend to be heavier: experimental encounters in mangrove-dwelling monitor lizards (Varanus indicus)

The evolution of male-biased sexual size dimorphism is often explained by sexual selection providing competitive advantage to the larger males. The aggressive interactions are often dangerous and

Dominance relationships in harems of female Red-winged blackbirds

We investigated the factors determining dominance in aggressive encounters between female Red-winged Blackbirds (Agelaius phoeniceus) resident on territories of single males. Three male territories



A Field Study of the Ontogeny of Social Behavior in the Lizard Anolis Aene Us

The spacing behavior, displays and aggression of hatchling and juvenile lizards (Anolis aeneus) were compared to the behavior of the adults. Tn adults these behaviors are sexually dimorphic, but


Intraspecific variation in home-range area is investigated using observations on 896 individuals in four Anolis species distributed over 16 sites in the Bahamas, possibly indicating variation from a territorial to a wide-ranging, nonterritorial strategy.

Aggression in the Lizard Anolis acutus

Most aggressive encounters observed were of low intensity, and high intensity encounters were more common in disturbed than in undisturbed populations, which allowed a quantitative study of the relationship between territory and aggression.


Four displays, designated according to their apparent social function as assertion, chal- lenge, courtship, and submission, in the behavioral repertoire of the green anole, Anolis carolinensis are

Dominance and the Acquisition of Superior Home Ranges in the Lizard Uta Stansburiana

A survivorship—based multivariate index of home range quality showed that dominants originated from home ranges of higher overall quality than those subordinates.

Time Budget, Niche Overlap, Inter- and Intraspecific Aggression in Anolis humlis and A. limifrons from Costa Rica

A time-budget analysis assessed the nature and frequency of intraspecific and interspecific interactions in natural, undisturbed anole populations and established field foraging sites in terms of perch height and diameter components of the structural habitat.

A Neuroethological Study of Display Behavior in the Lizard Anolis Carolinensis (Reptilia, Lacertilia, Iguanidae)

An analysis of the effects of forebrain lesions on two stereotyped displays indicated involvement of the striatal area of the basal forebrain in species-typical “challenge” displays that are characteristic of territorial encounters between adult conspecifics.

Evolution of Anoline Lizard Display Behavior

For some species display repertoire size seems to have evolved from a single display to repertoires of multiple displays; these subsequent displays are generally restricted to aggressive interactions.
