... hydration state through dietary water intake. Recent studies performed in snakes, which are generalist carnivorous reptiles, suggest that the benefits of dietary water intake are negated by hydric costs of digestion. Most lizards are generalist insectivores that can shift their prey types, but firm...

...Caleb L. Loughran; Blair O. Wolf ABSTRACT Because most desert-dwelling lizards rely primarily on behavioral thermoregulation for the maintenance of active body temperature, the effectiveness of panting as a thermoregulatory mechanism for evaporative cooling has not been widely explored. We measured...

...: This Review highlights our understanding of postnatal neurogenesis in reptiles in comparison to mammals. Research in reptiles will help to address the mechanisms of postnatal neurogenesis and place it within a functional and evolutionary context. Neurogenesis Reptiles Lizards Neuronal proliferation...

...-force estimates in a diverse sample of lizards. Results indicate that both variables have a significant impact on the accuracy of measurements. Maximum bite force is significantly greater using leather as the biting substrate compared with a metal substrate. Less-forceful bites on metal are likely due...

...G. Beltrami; C. Bertolucci; A. Parretta; F. Petrucci; A. Foà SUMMARY The present study first examined whether ruin lizards Podarcis sicula are able to orientate using the e-vector direction of polarized light. Ruin lizards were trained and tested indoors, inside a hexagonal Morris water maze...

... to reveal variation in feeding function,but allows testing of the functional role of the phases of the gape cycle. The jaw kinematics of two species of lizards are analyzed when feeding trials are conducted using quantitative control of prey mass, hardness and mobility. For both species, there were...

...Mats Olsson; Mark Wilson; Caroline Isaksson; Tobias Uller; Beth Mott SUMMARY We performed experiments on male Australian painted dragon lizards( Ctenophorus pictus ) to test the hypothesis that carotenoids can scavenge reactive oxygen species (ROS), protecting the organism from oxidative stress...

...Eric J. McElroy; Kristin L. Hickey; Stephen M. Reilly SUMMARY Foraging mode has molded the evolution of many aspects of lizard biology. From a basic sit-and-wait sprinting feeding strategy, several lizard groups have evolved a wide foraging strategy, slowly moving through the environment using...

...Tobias Wang; David R. Carrier; James W. Hicks ABSTRACT The extent to which lizards ventilate their lungs during locomotion is controversial. Direct measurements of airflow across the nostrils suggest a progressive reduction in tidal volume and minute ventilation with increased running speed, while...

...C. T. Farley; M. Emshwiller ABSTRACT Nocturnal geckos can walk on level ground more economically than diurnal lizards. One hypothesis for why nocturnal geckos have a low cost of locomotion is that they can perform mechanical work during locomotion more efficiently than other lizards. To test...

...Dale Ritter ABSTRACT Lateral bending of the trunk during terrestrial, quadrupedal locomotion was analyzed in four species of lizards, using high-speed videography and computerized motion analysis. The focus of the analysis was whether lizards produce a standing or a traveling wave of bending...

...Barry Sinervo; Richard Hedges; Stephen C. Adolph ABSTRACT Decreased mobility of gravid females is thought to be an important cost of reproduction in lizards. We measured sprint speeds of female western fence lizards (Sceloporus occidentalis Baird and Girard) before and after they had oviposited...

...K. Johansen; A. S. Abe; J. H. Andresen ABSTRACT The central circulation in the lizard Tupinambis teguixin (Linné, 1758) was studied using angiocardiographic techniques. Contrast medium was selectively injected into the vena cava superior, the sinus venosus, the right atrium, and the ventricular...

...M. L. Glass; N. Heisler ABSTRACT The effects of hypercapnia on the arterial acid-base status of the Tegu lizard, Tupinambis nigropunctatus (Spix), were studied at 25 °C. Arterial increased over the first 2 h of hypercapnia causing a fall in arterial plasma pH (pH a ) of about 0·17 units with ≈4% CO...

...Kathleen K. Smith; William L. Hylander ABSTRACT Single-element strain gauges were placed across the mesokinetic joint of the skull of the savanna monitor lizard, Varanus exanthematicus Bose, in order to document the extent and timing of mesokinetic movement. In addition, rosette strain gauges were...
