What does the word aestivation refer to in the animal kingdom?

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. ... It takes place during times of heat and dryness, the hot dry season, which are often the summer months.

What is the meaning of aestivation in biology?

Aestivation or estivation is the positional arrangement of the parts of a flower within a flower bud before it has opened. Aestivation is also sometimes referred to as praefoliation or prefoliation, but these terms may also mean vernation: the arrangement of leaves within a vegetative bud.

Why do animals aestivate?

Aestivation occurs in animals living in deserts and tropical regions. This is done to protect themselves from hot and dry climate, and due to the scarcity of food water. This can be seen in earthworms, molluscs, arthropods, reptiles and amphibians. A lungfish can aestivate and survive without water for three years.

What is aestivation and why might it be considered a type of dormancy?

Aestivation is the name given to a period of summer dormancy. Summer dormancy is often exhibited by animals when conditions become unfavourable. For example, should summer temperatures fall below a specific threshold an insect might aestivate in its pupal state rather than emerge. ... Summer dormancy.

Who discovered aestivation?

The aestivation hypothesis is a hypothesized solution to the Fermi paradox conceived in 2017 by Anders Sandberg, Stuart Armstrong and Milan M. Ćirković.

What is aestivation example?

Eg- China rose, ladyfinger, cotton etc. 3) Imbricate - If the margins of sepals or petals overlap one another but not in any particular direction. Ex- Cassia and gulmohar. 4) Vexillary - In pea and bean flower, there are 5 petals, the largest (standard) overlaps the lateral petals (wings)

What is aestivation in snail?

Aestivation. During the heat of the day and the dry hours of noon, snails remain in a dormant state called aestivation or dryness sleep. ... Snails that remain outside during their aestivation can usually be recognized by a rather brightly coloured shell, reflecting the sunlight and so minimizing evaporation.

What is Vexillary aestivation?

Vexillary aestivation is the arrangement of corolla in which the anterior petal is innermost and posterior petal is outermost and largest. It is also called as descending imbricate. Papilionaceae flower shows vexillary aestivation. There is large petal which has two lobes fused.

What is aestivation in biology class 11?

Aestivation or estivation is the positional organisation of the sections of the flower inside the bud of the flower before it is opened. That is also the manner in which sepals or petals are arranged in a flower bud with respect to the other members of the same whorl.

When and why do some animals like snails go into aestivation?

When the snails are not able to migrate from the stressful conditions in the habitat, they undergo aestivation to avoid stress by escaping in time. It occurs in summer or dry season, animals like snails go into aestivation to avoid summer-related unfavorable problems the animals.

What is the difference between hibernation torpor and aestivation?

Torpor involves physiological changes related especially to body temperature, metabolism, and water balance. Hibernation is when an organism spends the winter in a state of dormancy; it is long-term multiday torpor for survival of cold conditions. Estivation is summer dormancy, for survival of hot and dry periods.

What is aestivation describe various types of aestivation?

Aestivation means arrangement of accessory floral organs(sepals or petals) in relation to one another in a flower. Some types of Aestivation: -Open: Margins of adjacent petals are not overlapping / touching others. -Twisted: One margin of a petal overlaps regularly the margin of an adjacent petal.

What animals show aestivation?

Reptiles and amphibians

Non-mammalian animals that aestivate include North American desert tortoises, crocodiles, and salamanders. Some amphibians (e.g. the cane toad and greater siren) aestivate during the hot dry season by moving underground where it is cooler and more humid.

During which period does the frog show aestivation?

That's why frogs undergo dormancy stages in summer. This summer sleep is known as aestivation. Hence, the answer is “Summer”.

How do crocodiles Aestivate?

3. Like most reptiles, crocodiles are cold-blooded animals and prefer to take up residence in tropical areas close to wetlands. They cannot generate heat on their own, therefore they go into a period of long sleep (or aestivation, a similar state to hibernation) until the weather heats up again.
