Cardiorespiratory synchrony in turtles.
Many reptiles, particularly diving species, display characteristic cardiovascular changes associated with lung ventilation (cardiorespiratory synchrony). Previous studies on freshwater turtles show that heart rate and pulmonary blood flow rate (Qpul) increase two- to fourfold during ventilation compared with breath-holding, and some studies report concomitant decreases in systemic blood flow ra...

متن کاملPhysiological thermoregulation in turtles.
WEATHERS, WESLEY W., AND FRED N. WHITE. Physiological thermoregulafion in turtles. Am. J. Physiol. 22 l(3) : 704-7 10. 17 I. .The physiological capacity of turtles for altering rates of heat exchange was partially assessed by measuring rates of change of body temperature (Tb) during heating from 10 C to 30 C, and during cooling from 30 C to 10 C, in both air and water. In water, turtles heated ...
متن کاملHatching behavior in turtles.
Incubation temperature plays a prominent role in shaping the phenotypes and fitness of embryos, including affecting developmental rates. In many taxa, including turtles, eggs are deposited in layers such that thermal gradients alter developmental rates within a nest. Despite this thermal effect, a nascent body of experimental work on environmentally cued hatching in turtles has revealed unexpec...
متن کاملCancer in sea turtles.
Sea Turtles Sea turtles are one of the oldest extant groups of animals, and they have changed little in basic anatomy for millions of years. Sea turtles are found throughout the world, and depending on the species, range from warm tropical water to frigid oceans near the arctic. They can be herbivores, omnivores, or carnivores and can be quite large. For example, the largest species of sea turt...
