Sexual dimorphism in the Neotropical lizard, Tropidurus torquatus (Squamata, Tropiduridae)

Amphibia-Reptilia, 2005
Abstract We describe the sexual dimorphism in coloration, body shape, and body size in Tropidurus torquatus, a widely distributed lizard species in central Brazil. Adult males have colored patches varying from yellow to yellow-and-black, and black on the abdomen, ventral aspect of the thighs ...

Growth in a population of Liolaemus wiegmannii (Squamata: Tropiduridae) in Central Argentina

Amphibia-Reptilia, 1998
Abstract Size frequencies in a population of the lizard Liolaemus wiegmannii were determined throughout the year, to evaluate the effects of recruitment and mortality on the population structure, and to estimate the daily growth rate and its variation.

Ecological constraints to match field and preferred temperatures in lizards Tropidurus catalanensis (Squamata; Tropiduridae)

Journal of Thermal Biology, 2021
We compared microhabitat and body temperatures in the field with thermal preferences of Tropidurus catalanensis to investigate if they match or diverge as demonstration respectively of suitability or poor-quality of the thermal environment. As T. catalanensis is subjected to variable thermal conditions along its distribution and may be jeopardized by ...

Home Range of the Saxicolous Lizard Tropidurus itambere (Tropiduridae) in Southeastern Brazil

Copeia, 1997
environment and to the presence of other individuals of the same species (Brown and Orians, 1970). The spatial distribution plays a fundamental role in social behavior, and much of the diversity in vertebrate mating systems may be understood based on the spacing pattern of the population (Smith, 1985).

Vocalization as a Response to Capture in the Central Chilean Lizard Liolaemus chiliensis (Tropiduridae)

Studies on Neotropical Fauna and Environment, 2001
Among 11 Liolaemus lizard species examined in central and south-central Chile only L. chiliensis responded to capture and handling by vocalizing. Vocalizations sounded more like a squeak than a hiss, and volume was sufficient to be heard at a distance of ~3 m.

Cranial myology of some species of Liolaemus and Phymaturus (Squamata: Tropiduridae: Liolaeminae)

Amphibia-Reptilia, 1998
Abstract The cranial musculature of 19 species of Liolaemus and two species of Phymaturus was compared and analyzed for taxonomic significance. Using 52 myological cranial characters a cladistic analysis of the taxa mentioned was performed.

The Reproductive Cycle of Tropidurus itambere (Sauria: Tropiduridae) in Southeastern Brazil

Journal of Herpetology, 1993
The reproductive cycle of the lizard Tropidurus itambere was studied in an open area near Campinas, Sao Paulo State, southeastern Brazil. Females had vitellogenic follicles or oviductal eggs only during the wet season, whereas males had large testes with spermatozoa throughout the year.

Two new species of lizards of the genus Stenocercus (Iguania, Tropiduridae) from central Peru

Zootaxa, 2015
We describe two new species of Stenocercus from the Andes of central Peru (Departamento Ancash): Stenocercus amydrorhytus sp. nov. from elevations between 2810 and 3075 m and S. johaberfellneri sp. nov. from elevations between 3120 and 3200 m. Stenocercus amydrorhytus is most similar to S. ivitus, S. chrysopygus, S. melanopygus, S.

Insights on the sleep ecology of Tropidurus hispidus (Spix, 1825) (Squamata: Tropiduridae)

The Herpetological Journal
We report preliminary data on the sleep ecology of Tropidurus hispidus (Tropiduridae) lizards based on six observations of sleeping lizards in natural settings, and highlight how standard monitoring techniques can be useful to study lizard sleep behaviour.
