Ventilation and gas-exchange in the tegus lizard tupinambis-tequixin at different temperatures
(Brazilian Journal of Medical and Biological Research, 1981-01-01) [Resumo]
Experimental and field record of preferred temperature in the neotropical amphisbaenid Amphisbaena mertensi stauch (reptilia, amphisbaenidae)
(Comparative Biochemistry and Physiology A: Physiology, 1984-12-01) [Artigo]
1. 1. Temperature preference in experimental thermal gradient in the laboratory was determined and field preferred temperature was recorded, for Amphisbaena mertensi. 2. 2. Mean preferred temperature in 52 experiments ...
Phylogeny, Ecology, and Heart Position in Snakes
(Physiological and Biochemical Zoology, 2010-01-01) [Artigo]
The cardiovascular system of all animals is affected by gravitational pressure gradients, the intensity of which varies according to organismic features, behavior, and habitat occupied. A previous nonphylogenetic analysis ...
Seasonal changes in daily metabolic patterns of tegu lizards (Tupinambis merianae) placed in the cold (17 degrees C) and dark
(Physiological and Biochemical Zoology, 2008-03-01) [Artigo]
Oxygen consumption rate was measured continuously in young tegu lizards Tupinambis merianae exposed to 4 d at 25 degrees C followed by 7-10 d at 17 degrees C in constant dark at five different times of the year. Under these ...
Circadian pattern of Bothrops moojeni in captivity (Serpentes: Viperidae)
(Journal of Venomous Animals and Toxins Including Tropical Diseases, 2012-01-01) [Artigo]
Members of the subfamily Crotalinae are considered to be essentially nocturnal and most of the data about these snakes have been collected from the field. Information on how nutritional status affects the movement rate and ...
Regulation of cardiac filling and stroke volume in Synbranchus marmoratus
(Comparative Biochemistry and Physiology A-molecular & Integrative Physiology, 2006-04-01) [Resumo]
Metabolic response to feeding in Tupinambis merianae: Circadian rhythm and a possible respiratory constraint
(Physiological and Biochemical Zoology, 2006-05-01) [Artigo]
The diurnal tegu lizard Tupinambis merianae exhibits a marked circadian variation in metabolism that is characterized by the significant increase in metabolism during part of the day. These increases in metabolic rate, ...
Heat Exchange from the Toucan Bill Reveals a Controllable Vascular Thermal Radiator
(Science, 2009-07-24) [Artigo]
The toco toucan (Ramphastos toco), the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, from serving as a ...
Does autonomic regulation of heart rate optimise oxygen uptake in teleost fishes?
(Comparative Biochemistry and Physiology A-molecular & Integrative Physiology, 2008-07-01) [Resumo]
Minimal volume regulation after shrinkage of red blood cells from five species of reptiles
(Comparative Biochemistry and Physiology A-molecular & Integrative Physiology, 2008-05-01) [Artigo]
Red blood cells (RBCs) from most vertebrates restore volume upon hypertonic shrinkage and the mechanisms underlying this regulatory volume increase (RVI) have been studied extensively in these cells. Despite the phylogenetically ...
