Aggression is an important component of behavior in many animals and may be crucial to providing individuals with a competitive advantage when resources are limited. Although much is known about the effects of catecholamines and hormones on aggression, relatively few studies have examined the effects of physical performance on aggression. Here we use a large, sexually dimorphic teiid lizard to test whether individuals that show high levels of physical performance (bite force) are also more… 
The role of size and aggression in intrasexual male competition in a social lizard species, Egernia whitii
It is suggested that aggression may be important in other functional contexts, such as parental care, and that alternative traits,such as fighting experience, may beImportant in determining competition outcome in this species.
Aggression, color signaling, and performance of the male color morphs of a Brazilian lizard (Tropidurus semitaeniatus)
The results suggest that Yellow males might undertake a sneaker tactic, preventing aggression costs by evasiveness even though they might perform similarly to Black males, and show that dominance is highly correlated to chest’s intensity of dark yellow colorations and that lizards signal their dominance status through displays of head bob bouts.
Choose Your Weapon: Defensive Behavior Is Associated with Morphology and Performance in Scorpions
Morphology can be adaptive through its effect on performance of an organism. The effect of performance may, however, be modulated by behavior; an organism may choose a behavioral option that does not
Proximate determinants of bite force capacity in the mouse lemur
The results suggest that bite force in the grey mouse lemur is mostly determined by morphology and age, yet is independent of variation in testoster-one, and age was highly significantly and positively correlated with bite force.
Covariations between personality behaviors and metabolic/performance traits in an Asian agamid lizard (Phrynocephalus vlangalii)
The idea that behaviors in life-history trade-offs are natural history-dependent in P. vlangalii supports the idea that activity/exploration or risk-taking behaviors are more likely to impact resource acquisition for organisms foraging on clumped and ephemeral food sources, and evidence that behavioral types play functional roles in life historyTrade-offs to supporting POLS hypothesis is provided.
Sexual Selection and Dynamics of Jaw Muscle in Tupinambis Lizards
It is proposed that the pterygoideus muscle may act as a signal of reproductive condition of males because it is associated with testis size and sperm presence and the results suggest that jaw muscle as sexual character could be influenced by inter- and intrasexual selective pressures.
Linear versus geometric morphometric approaches for the analysis of head shape dimorphism in lizards
Geometric morphometric approaches provided better insights into the underlying functional relationships between the cranium and the jaw musculature, as illustrated by shape differences in muscle insertion areas not detected using linear morphometric data.
Drivers and patterns of bite force evolution in liolaemid lizards
The jaw system of liolaemid lizards is used to investigate the drivers of in vivo bite force variation and test for differences in evolutionary rates in morphology and performance, showing high rates of evolution for performance traits compared to morphological traits such as external head dimensions.
Do exploration and risk-taking behaviors covary with metabolism and performance in an Asian agamid lizard ([i]Phrynocephalus vlangalii[i])?
Ecological factors related to predation risks and foraging play major roles in determining which behavioral traits may mediate life history trade-offs and thus the pace-of-life syndrome structure


Bite-Force Performance Predicts Dominance in Male Venerable Collared Lizards (Crotaphytus antiquus)
Staged interactions between body size-matched male Venerable Collared Lizards (Crotaphytus antiquus) in the laboratory showed the strong role of weapon performance, as opposed to weapon morphology, in determining dominance.
Locomotor performance and dominance in male Tree Lizards, Urosaurus ornatus
The results suggest a link between hormones, performance and behaviour in territorial lizards, and dominance behaviour and locomotor performance are strongly associated.
Effect of body size on aggression in the ant, Cataglyphis niger (Hymenoptera; Formicidae)
Although the capacity to recognize nestmates was shared by all individuals, some patterns of agonistic behaviors were size related, and Escape was mostly displayed by the small workers, and threat, associated with ritualized fights, by the large workers.
Morphology, performance and fighting capacity in male lizards, Gallotia galloti
The finding that bite performance is linked to dominance fits in with the high sexual dimorphism in head size in this species, as head size is a predictor of bite force performance.
Fight versus flight: physiological basis for temperature-dependent behavioral shifts in lizards
Differences in the physiological properties of jaw versus limb muscle were observed that enhance the ability of the jaw muscle to generate maximal force at all temperatures tested, showing how behavioral responses may be determined by the limitations set by temperature on physiological processes.

It is shown that the evolution of hindlimb length in apes is inversely correlated with the development of body size sexual dimorphism (SSD), which is consistent with the suggestion that selection for fighting performance has maintained relatively short hindlimbs in species of Hominoidea with high levels of male–male competition.
Testosterone supplementation in juvenile Psammodromus algirus lizards: consequences for aggressiveness and body growth
It is suggested that although an elevated testosterone level may have positive effects on aggressiveness and activity, it also may have negative effects manifested as reduced growth rate and body condition.
