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 ]
Reptiles that are dormant in the winter tend to have higher survival rates and slower aging. [50] Reptiles evolved to exploit their ectothermy to deliberately cool their internal body temperatures. As opposed to mammals or birds, which will prepare for their hibernation but not directly cause it through their behavior, reptiles will trigger ...
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 ...
But snakes and alligators do go into a similar state when temperatures begin to drop to help them survive the cold. Just as some warm-blooded animals hibernate during the winter as they endure ...
The eastern long-eared bat uses torpor during winter and is able to arouse and forage during warm periods. [25] Some animals use torpor during their reproductive cycle, as seen in unpredictable habitats. [24] They experience the cost of a prolonged reproduction period but the payoff is survival to be able to reproduce at all. [24]
Soon after feeding, close to the end of summer, the adult snakes return to their dens for winter hibernation. [4] The young snakes, around one-year-old, spend more time in marshy areas to find food before the winter temperatures arrive and hibernate there as their small size makes them unnoticeable to predators. [8] During hibernation, the ...
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 ...
Tiger rattlesnakes are terrestrial snakes and are nocturnal during the hot summer (June–August), but become diurnal and crepuscular during the fall season. They hibernate during the late fall and winter in rock crevices or animal burrows. In spite of being ground-dwelling, their activity is not restricted to the ground.
