The relationship between hard and soft tissue structures of the eye in extant lizards. [PDF]

J Morphol, 2022
The sizes of the eye structures are important factors for the visual sensitivity. Strong correlations were found between the size of the scleral ossicle ring and soft tissue structures in extant squamates eyes. These correlations will allow reliable estimations of soft structures and inferences on the visual sensitivity and mode of life in fossil ...

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.

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.

Unraveling patterns and drivers of saurophagy in South American lizards [PDF]

Scientific Reports
Predation plays a crucial role in community structure and population dynamics, influencing the evolution of various groups. Lizards occupy a central position in predator–prey networks, with some species engaging in saurophagy—where they act as both ...

A most unusual tail: Scoliosis in a wild Australian skink, and reported incidences and suggested causes of similar malformations amongst squamates

Austral Ecology, Volume 47, Issue 3, Page 723-728, May 2022., 2022
AbstractMalformations of vertebrae potentially occur across many taxa, particularly in Testudines, which are susceptible to kyphosis (dorsoventral curvature of the spine). Such malformations may stem from either genetic or environmental origins, and their prevalence and associated impacts on survival remain poorly understood.

Morphological study of the integument and corporal skeletal muscles of two psammophilous members of Scincidae (Scincus scincus and Eumeces schneideri)

Journal of Morphology, Volume 282, Issue 2, Page 230-246, February 2021., 2021
Photograph of holocrine glands between the folds of the skin of Scincus scincus. Compound osteoderms are located on both sides. The skin surface is visible on the upper right side. Abstract Sand deserts are common biotopes on the earth's surface. Numerous morphological and physiological adaptations have appeared to cope with the peculiar conditions ...
