Are hemipenial traits under sexual selection in Tropidurus lizards? Hemipenial development, male and female genital morphology, allometry and coevolution in Tropidurus torquatus (Squamata: Tropiduridae). [PDF]

PLoS ONE, 2019
Male genitalia show considerable morphological variation among animals with internal fertilization and exhibit a high level of evolvability in lizards.

Territory quality and male dominance in Tropidurus torquatus (Squamata, Tropiduridae) [PDF]

Phyllomedusa: Journal of Herpetology, 2006
In territorial species, females are often attracted by high-quality territories, which are expected to be owned by males that successfully won competition with other males.

The demography of the lizard Tropidurus torquatus (Squamata, Tropiduridae) in a highly seasonal Neotropical savanna [PDF]

Phyllomedusa: Journal of Herpetology, 2003
The demography of the lizard Tropidurus torquatus (Squamata, Tropiduridae) in a highly seasonal Neotropical savanna. The demography of a population of Tropidurus torquatus was studied from March 1996 until December 1998, in the Cerrado biome of central ...

Effects of incubation temperature on development, morphology, and thermal physiology of the emerging Neotropical lizard model organism Tropidurus torquatus [PDF]

Scientific Reports, 2022
Incubation temperature is among the main phenotypic trait variation drivers studied since the developmental trajectory of oviparous animals is directly affected by environmental conditions.

Bipedal locomotion in Tropidurus torquatus (Wied, 1820) and Liolaemus lutzae Mertens, 1938 [PDF]

Brazilian Journal of Biology, 2008
Bipedalism has evolved on numerous occasions in phylogenetically diverse lizard families. In this paper we describe, for the first time, bipedal locomotion on South American lizards, the sand-dweller Liolaemus lutzae and the generalist Tropidurus ...

Connectivity among thermal habitats buffers the effects of warm climate on life-history traits and population dynamics. [PDF]

J Anim Ecol, 2022
Through its effects on movement, landscape fragmentation may influence the response of populations to climate change. This 3‐year‐long experiment on common lizards demonstrates that habitat connectivity can drastically change the impacts of warming on life‐history traits and population dynamics.

Closer to the Heart: Cardiac Muscle Aerobic Capacity Correlates With Intraspecific Variation in Sprint Performance Rather Than Androgen Levels in the Neotropical Lizard Tropidurus catalanensis. [PDF]

J Exp Zool A Ecol Integr Physiol
In male lizards Tropidurus catalanensis, sprint locomotor performance correlates with cardiac aerobic capacity. ABSTRACT Assessments of the interplay between physiology and whole‐organism performance are fundamental to understand how individuals function in different ecological contexts.

Ancient Introgression Explains Mitochondrial Genome Capture and Mitonuclear Discordance Among South American Collared Tropidurus Lizards. [PDF]

Mol Ecol
ABSTRACT Mitonuclear discordance—evolutionary discrepancies between mitochondrial and nuclear DNA phylogenies—can arise from various factors, including introgression, incomplete lineage sorting, recent or ancient demographic fluctuations, sex‐biased dispersal asymmetries, among others.

Divergent calcium signaling in RBCs from Tropidurus torquatus (Squamata--Tropiduridae) strengthen classification in lizard evolution. [PDF]

BMC Physiol, 2007
We have previously reported that a Teiid lizard red blood cells (RBCs) such as Ameiva ameiva and Tupinambis merianae controls intracellular calcium levels by displaying multiple mechanisms. In these cells, calcium stores could be discharged not only by: thapsigargin, but also by the Na+/H+ ionophore monensin, K+/H+ ionophore nigericin and the H+ pump ...
