SummaryA laboratory experiment with the broad-headed skink (Eumeces laticeps) involving staged agonistic encounters demonstrates that larger males have an advantage over smaller ones in agonistic bouts. Field data on head wounds produced by intraspecific fighting during the breeding season show a much higher frequency of new wounds among males over 100 mm in snout-vent-length than in smaller males. The significant difference in new-wound frequency strongly suggests avoidance of fights by the… 
Chemosensory Recognition of Familiar and Unfamiliar Conspecifics by the Scincid Lizard Eumeces laticeps
TLDR
It is indicated that both sexes of broad-headed skinks can discriminate between chemical stimuli of familiar and unfamiliar individuals of the opposite sex and that males can distinguish their own cloacal chemicals from those of unfamiliar males.
Effects of female presence on intrasexual aggression in male lizards, Podarcis hispanicus
TLDR
It is suggested that the lack of information on the reproductive state of an unfamiliar female may be enough to decrease fighting motivation of an intruding male, if he has more expectations of success with his own familiar female.
Territory quality and male dominance in Tropidurus torquatus (Squamata, Tropiduridae)
TLDR
Testing the hypothesis that organismal traits in dominant males of the lizard Tropidurus torquatus are associated with the quality of the territory owned found that high-quality territories were associated with larger males that had longer heads, while males occupying low- quality territories exhibited more head displays, traveled larger distances and ran slightly slower than those associated with high- Quality territories.
Sexual selection versus alternative causes of sexual dimorphism in teiid lizards
TLDR
Observational field data were used to tentatively conclude that intrasexual selection was the cause of larger body size of C. tigris males relative to females because larger males won in male aggressive interactions and had higher reproductive success.
AGGRESSIVE BEHAVIORS AND THEIR EFFECT ON RESOURCE USE BY MALE LITTLE BROWN SKINKS, SCINCELLA LATERALIS
The aggressive behaviors of adult male Little Brown Skinks, Scincella lateralis, and their effects on access to an important resource (a single retreat) were the subject of a study consisting of 10
Chemosensory cues allow male lizards Psammodromus algirus to override visual concealment of sexual identity by satellite males
TLDR
Large males of the lizard Psammodromus algirus reacted aggressively to young intruder males despite their female-like coloration, suggesting that they might have the ability to recognize competitor males by chemosensory cues.
Reproduction in the Arenicolous Mexican Lizard Uma exsul
TLDR
Uma exsul and Mexican Uma paraphygas mature early and are short lived, consistent with an r-selected life-history strategy, compared with the North American species Uma scoparia, Uma inornata, and Uma notata, which exhibit K-selected characteristics.
Intraspecific Aggression in Neonate Common Five-Lined Skinks (Plestiodon fasciatus)
TLDR
It is suggested that, in the field, small neonates usually will be subordinate to (and avoid) larger ones while active on the surface, but will readily share retreat sites with larger neonates.
The Evolution of Performance‐Based Male Fighting Ability in Caribbean Anolis Lizards
TLDR
It is suggested that more dimorphic (and hence more territorial) species escalate to biting during fights more readily compared with less territorial species, and the ecological and behavioral qualities of species may modify both the shape and the size of sexually selected traits as well as the nature of the information those traits convey.

The evolution of sexual dimorphism in the skink Eumeces laticeps: an example of sexual selection
TLDR
Both sexes are capable of eating prey much larger than the mean or maximum size of prey found in stomachs, suggesting that resource partitioning is a consequence of sexual size differences rather than a cause.
Blue tails and autotomy: enhancement of predation avoidance in juvenile skinks
TLDR
Repeated predation without ill effects by several predators allows rejection of the hypothesis that the blue tail is aposematic for the predators tested, and the trend of predation rates on blue- and black-tailed hatchlings is in the direction predicted for inhibition.
Skink Reproduction and Sexual Dimorphism: Eumeces fasciatus in the Southeastern United States, with Notes on Eumeces inexpectatus
TLDR
Clutches brooded in the laboratory revealed that eggs increase in mass considerably during development, but offspring hatch at a size much smaller than eggs at deposition, in addition, significant differences were found in hatchling size among clutches.

Induction of Orange Head Coloration and Activation of Courtship and Aggression by Testosterone in the Male Broad-headed Skink (Eumeces laticeps)
TLDR
Intraperitoneal implantation of testosterone propionate in Silastic capsules restores the bright orange head coloration and activates court- ship and agonistic behaviors in castrated males.
INTRASPECIFIC AND INTERSPECIFIC AGGRESSION IN LIZARDS OF THE SCINCID GENUS EUMECES: CHEMICAL DETECTION OF CONSPECIFIC SEXUAL COMPETITORS
TLDR
Male E. inexpectatus did not behave aggressively toward male E. fasciatus, and could recognize conspecific males by a species-identifying odor, suggesting that it may have evolved through intraspecific selection for ability to recognize sexual competitors or by direct selection against interspecific fighting.
Home-Range Size and Overlap in Sceloporus undulatus erythrocheilus (Reptilia: Iguanidae)
TLDR
A population of the rock-inhabiting lizard, Sceloporus undulatus erythrocheilus, was studied over two activity seasons in the eastern Colorado foothills and the large degree of male home-range overlap suggests that home range is not equal to territory in this population.

TLDR
A natural selection model is developed to predict the equilibrium frequencies of the two male types: cuckoldry or parental care and a preliminary test of the model provides qualitative agreement.
Foraging and Diet of a Diurnal Predator (Eumeces laticeps) Feeding on Hidden Prey
TLDR
The diet of Eumeces laticeps consists of a variety of insects and their larvae, snails, isopods, spiders, Anolis lizards, and even juvenile EumECes, and various measures of prey size correlate with size of the lizards' trophic structures.
