Altered Thermoregulation in the Iguana Dipsosa Urus Dorsalis following Exercise
-1. Seven desert iguanas ran on a motorized treadmill for 20-min periods. Before, during and after exercise, the iguanas were in a thermal gradient which allowed them to thermoregnlate behaviourally. 2. For several hours following exercise, the iguanas selected warmer ambient temperatures, resulting in small, but statistically significant, increases in body temperature. 3. The increases in temp...
متن کاملBehavioral thermoregulation by turtle embryos.
Mobile ectothermic animals can control their body temperatures by selecting specific thermal conditions in the environment, but embryos--trapped within an immobile egg and lacking locomotor structures--have been assumed to lack that ability. Falsifying that assumption, our experimental studies show that even early stage turtle embryos move within the egg to exploit small-scale spatial thermal h...
متن کاملThe link between autonomic and behavioral thermoregulation
The human thermoregulatory apparatus has both autonomic and behavioral mechanisms at its disposal. Behavioral mechanisms include changing of clothes, moving to warmer/cooler/shaded areas and changing the environment by operating windows or the thermostat. For autonomous thermoregulation the body relies on metabolic responses to increase heat production, and besides sweating also on cardiovascul...
متن کاملBehavioral thermoregulation in mammals: a review.
In mammals, thermoregulation is a key feature in the maintenance of homeostasis. Thermoregulatory capacities are strongly related to energy balance and animals are constantly seeking to limit the energy costs of normothermia. In case of thermal changes, physiological mechanisms are enhanced, increasing rates of energy expenditure. However, behavioral adjustments are available for species to low...
متن کاملAlfaxalone anaesthesia in the green iguana (Iguana iguana).
OBJECTIVE To characterise the anaesthetic effects of alfaxalone administered intramuscularly (IM) at 10, 20, and 30 mg kg(-1) . STUDY DESIGN Prospective, randomized cross-over study. ANIMALS Ten juvenile green iguanas (Iguana iguana) of mean body weight (±SD) 480 ± 134 g. METHODS Alfaxalone was administered IM in the triceps of both thoracic limbs. Times for anaesthetic induction, plateau...
