...Frank E. Fish; Sandra A. Bostic; Anthony J. Nicastro; John T. Beneski SUMMARY Crocodilians, including the alligator ( Alligator mississippiensis ), perform a spinning maneuver to subdue and dismember prey. The spinning maneuver, which is referred to as the `death roll',involves rapid rotation about...

... temperature fluctuations. Reptiles may also be active at seasonally varying body temperatures and could, therefore, gain selective advantages from regulating biochemical capacities. Hence, we tested the hypothesis that a reptile (the American alligator Alligator mississippiensis ) that experiences pronounced...

... alligators ( Alligator mississippiensis ) were used to examine the relationships between depolarization of the right ventricle,depolarization/contraction of the cog-wheel valve muscle and the resultant right ventricular, pulmonary artery and systemic pressures. Depolarization swept across the right ventricle...

In chronically cannulated and undisturbed amphibians and reptiles, the pH changes in arterial blood are, nevertheless, reduced by a concomitant respiratory acidosis (increased caused by a relative hypoventilation). Alligators ( Alligator mississippiensis ) have been reported to exhibit exceptionally large...

This study reports measurements of in vivo locomotor strain from the limb bones of lizard ( Iguana iguana ) and crocodilian ( Alligator mississippiensis ) species, animals from previously unsampled phylogenetic lineages with non...

... quantifies the sprawl and high walk kinematics of the alligator Alligator mississippiensis moving at different speeds on a treadmill and compares them with kinematic data available for other vertebrates. These data allow us to examine the effects of speed on crocodilian postures and to examine how...

...Luiz Guilherme S. Branco; Stephen C. Wood ABSTRACT Central chemoreceptor function was assessed in unanesthetized alligators, Alligator mississippiensis , at body temperatures of 15, 25 and 35°C. Two experiments were performed. In the first experiment, the fourth ventricle was perfused with mock...
