Ventilatory compensation of the alkaline tide during digestion in the snake Boa constrictor
(Journal of Experimental Biology, 2004-03-01) [Artigo]
The increased metabolic rate during digestion is associated with changes in arterial acid-base parameters that are caused by gastric acid secretion (the 'alkaline tide'). Net transfer of HCl to the stomach lumen causes an ...
Autonomic control of heart rate during forced activity and digestion in the snake Boa constrictor
(Journal of Experimental Biology, 2001-10-01) [Artigo]
Reptiles, particularly snakes, exhibit large and quantitatively similar increments in metabolic rate during muscular exercise and following a meal, when they are apparently inactive. The cardiovascular responses are similar ...
Effects of temperature on lung and blood gases in the South American rattlesnake Crotalus durissus terrificus
(Comparative Biochemistry and Physiology A-molecular & Integrative Physiology, 1998-09-01) [Artigo]
The effects of temperature on lung and blood gases were measured in the South American rattlesnake (Crotalus durissus terrificus). Arterial blood and lung gas samples were obtained from chronically cannulated animals at ...
Relationship of venom ontogeny and diet in Bothrops
(Herpetologica, 1999-06-01) [Artigo]
We studied ontogenetic changes in venom toxicity of the pitvipers Bothrops jararaca and B. alternatus in order to evaluate the relationship between venom action and diet. Toxicity tests (LD50) were performed for the venoms ...
Red blood cells from the South American rattlesnake (Crotalus durissus terrificus) regulate volume incompletely following osmotic shrinkage and swelling in vitro
(Comparative Biochemistry and Physiology A-molecular & Integrative Physiology, 2000-09-01) [Artigo]
The ability of rattlesnake (Crotalus durissus terrificus) red blood cells to volume regulate in vitro has been investigated. Blood was drawn through a catheter inserted in the dorsal aorta and equilibrated to gas mixtures ...
Energetic and physiological correlates of prey handling and ingestion in lizards and snakes
(Comparative Biochemistry and Physiology - A Molecular and Integrative Physiology, 2001-03-19) [Trabalho apresentado em evento]
In this review, we summarize the energetic and physiological correlates of prey handling and ingestion in lizards and snakes. There were marked differences in the magnitude of aerobic metabolism during prey handling and ...
