Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
Adult wood frogs spend summer months in moist woodlands, forested swamps, ravines, or bogs. During the fall, they leave summer habitats and migrate to neighboring uplands to overwinter. Some may remain in moist areas to overwinter. Hibernacula tend to be in the upper organic layers of the soil, under leaf litter. By overwintering in uplands ...
An animal prepares for hibernation by building up a thick layer of body fat during late summer and autumn that will provide it with energy during the dormant period. During hibernation, the animal undergoes many physiological changes, including decreased heart rate (by as much as 95%) and decreased body temperature . [ 2 ]
When the temperatures begin to drop, snakes go into a state called brumation.This event acts as a type of hibernation for cold-blooded animals. “Cold temperatures cause reptiles and amphibians ...
The survival of amphibians and reptiles during winter is just as fascinating as the long migration of birds or the winter snooze of woodchucks and chipmunks. Exploring the Last Green Valley: Where ...
Water-holding frogs are ectothermic, [8] meaning they depend on external sources of body heat. Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high ...
Snakes across North Carolina hibernate individually in holes in the ground, Hall said. Very few species can make their own holes, so they often find stump holes and rodent burrows to spend much of ...
A frog is an amphibian characterized by long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail. Frogs are most noticeable through their call, which can be widely heard during the mating season. It is estimated that up to 20% of amphibian species may care for their young in one way or another, and there is a great ...
