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 ]
During summer or droughts, caimans may dig a burrow and go into a form of summer hibernation called aestivation. Female caimans build a large nest in which to lay their eggs. The nests can be more than 1.5 m (4.9 ft) wide. Female caimans lay between 10 and 50 eggs, which hatch within about six weeks.
They are small frogs, growing to 0.6 inches (1.5 cm) in length on average. Blanchard's cricket frogs hibernate during the cold months, beginning in late October, and emerging from hibernation in late March or early April. Breeding occurs from mid-May to mid-July. Females lay small clusters or single eggs. Tadpoles emerge in late summer ...
During the summer months, the ponds and other habitats that the lesser siren live in go through periods of drought, which leads to low water levels and possibly dried-up ponds. The lesser siren's strategy to withstand the rigors of these dry seasons is something called " aestivation ", or summer dormancy, which can last up to 35 weeks ...
They usually hibernate at temperatures between 1 and 15 degrees, the desert box turtles have designated overwintering or hibernation sites that are closely within their home range. The desert box turtles burrow themselves into the ground for about 35 cm with their hind sticking out.
Dermophis mexicanus, also known commonly as the Mexican burrowing caecilian or the Mexican caecilian, and locally as the tapalcua or tepelcua, is a species of limbless amphibian in the family Dermophiidae. The species is native to Mexico and Central America, where it burrows under leaf litter and plant debris.
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.
It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability of food, the season of the year or for mating.
