J Exp Biol (2020) 223 (17): jeb224139.
Published: 11 September 2020
...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...

...., 2001 ), which might explain why ovarian hormones could control female growth and lead to SSD in both female- and male-larger reptiles ( Starostová et al., 2013 ). The independence of SSD from male gonadal androgens explains why SSD is so evolutionarily plastic among lizards including geckos...

...Michelle N. Reichert; Deidre L. Brink; William K. Milsom The homolog to the mammalian carotid body has not yet been identified in lizards. Observational studies and evolutionary history provide indirect evidence for the existence of a chemoreceptor population at the first major bifurcation...

...-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...

..., primates do differ from lizards in that variation in total gape cycle duration is more evenly affected by variance in all the phases in primates, and total gape cycle variance is lower than its constituent phases. These data suggest that primates trade off variance in some phases for variance in others, so...

... 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...

...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...

Published: 1 March 1996
...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...
