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 PhysiolIn 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.

Pulmonary development in Squamata: Insights from embryonic studies using micro-CT. [PDF]
Dev DynAbstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

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

Miología craneal de Tropidurus melanopleurus (Squamata: tropiduridae)
, 1997 Se describe la musculatura craneal de Tropidurus melanopleurus. La misma coincide en general con la exhibida por otros Tropiduridae, para los cuales se ha postulado poseen un patrón miológico común que a la vez formaría parte de uno generalizado asignable a otros iguanios. Se destacan sin embargo como características propias para T.

Potential distribution of endemic lizards from Brazilian restingas: The present announcing the end. [PDF]
Ecol EvolWe evaluated the current and future potential distribution of the endemic lizards from Brazilian restingas and hypothesize that the ENMs will indicate alterations in the potential distribution of the restinga‐endemic lizards. Our models are robust enough to explain the suitable climatic zones for the occurrence of the studied species.

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae). [PDF]
Anat Rec (Hoboken)Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Ultrastructural study of spermatozoa of the neotropical lizards, Tropidurus semitaeniatus and Tropidurus torquatus (Squamata, Tropiduridae) [PDF]
Tissue and Cell, 1999 A detailed description of the sperm ultrastructure of Tropidurus semitaeniatus and T. torquatus is provided. Mature spermatozoa of T. semitaeniatus and T. torquatus are filiform and characterized by: apical portion of acrosome depressed; perforatorium single; epinuclear lucent zone well developed; midpiece short; mitochondria columnar; midpiece with ...

Trifold origin of the reptilian ear ossicle and its relation to the evolutionary modification of the temporal skull region. [PDF]
J AnatThe columella‐complex in reptile middle ears involves the footplate, columella shaft, and extracolumella. The latter is partly of quadrate developmental origin, whereas the footplate derives from the mesodermal otic capsule, the shaft and another part of the extracolumella from the hyoid arch.
