...) and snakes (Python molurus) are exposed to hyperoxia. In toads, hyperoxia caused similar elevations of arterial P CO 2 at 20 and 30°C, indicative of a temperature-independent oxygen-mediated drive to breathing, whereas P CO 2 was unaffected by hyperoxia in snakes at 25 and 35°C. These findings do not support...

... Burmese python (Python molurus). Independent of body mass, Burmese pythons possess a significantly lower standard metabolic rate and respond to feeding with a much larger metabolic response compared with water snakes. While fasting, pythons cease gastric acid and intestinal base secretion, both of which...

... pythons (Python molurus) experience similar increases in metabolic rate during the digestion of a meal as they do while crawling, hence each would have an equal demand for vascular supply when these two actions are combined. To determine, for the Burmese python, whether blood flow is prioritized when...

... the lungs from oedema. Within non-crocodilian reptiles, ventricular pressure separation has only been observed in varanid lizards and has been regarded as a unique adaptation to an active predatory life style and high metabolic rate. The systemic and pulmonary sides of the ventricle in Python molurus...

... python (Python molurus). We also report simultaneous measurements of arterial blood gases and haematological parameters. Arterial blood was obtained from chronically implanted catheters,and blood oxygen-dissociation curves were constructed from oxygencontent measurements at known oxygen partial pressure...

... very large cardiac shunts. Very little is known about the cardiac shunt patterns in other groups of reptiles. Here we characterise cardiac performance and flow dynamics in the Burmese python (Python molurus) using an in situ perfused heart preparation. The pericardium remained intact and the two atria...

... flow and stroke volume of Burmese pythons (Python molurus) while fasting at rest, exercising, digesting and exercising while digesting. All measured variables increased significantly during exercise (crawling at 0.4 km h −1 and at ), highlighted by a 17-fold increase in and a 24-fold increase...

... to digest the meal efficiently. The high energy cost of initiating digestion would thus be more than offset by the energy savings resulting from not maintaining the gut during the period of quiescence. The present paper extends these observations to the Burmese python (Python molurus), a snake species...
