Behavioral 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 کامل"Behavioral Thermoregulation by Turtle Embryos" (2011), by Wei-Guo Du, Bo Zhao, Ye Chen, and Richard Shine
In ?Behavioral Thermoregulation by Turtle Embryos,? published in Proceedings of the National Academy of Sciences [4] in April, 2011, Wei-Guo Du, Bo Zhao, Ye Chen, and Richard Shine report that turtle embryos can move towards warmer temperatures within the egg [5] when presented with a small, 0.8 degrees Celsius gradient. This behavioral thermoregulation may benefit the embryo?s fitness by accel...
متن کاملBehavioral thermoregulation by fishes: a new experimental approach.
Electronic equipment allows fishes, by their spatial movements, to regulate the temperature in experimental tanks. Swimming into warmer water causes the temperature of the entire tank to increase; conversely, swimming into cooler water causes the temperature to decrease. The technique may be adapted for studying simultaneous behavioral regulation of temperature and nonthermal factors.
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...
