Have you ever thought about how animals survive the cold winters? Through millions of years, animals have evolved and acquired adaptations that allowed them, and even allow them, to cope with the cold temperatures. For example, migration is a type of strategy with which animals can flee from icy areas to the area where temperatures are warmer or more conducive. Another type of strategy is the state of lethargy or sleeping organisms when temperatures are very cold.
Precisely, on one of these bedroom strategies we will develop this interesting post of ecology, more specifically about What is the mists and examples of animals that bruman. If you are interested in learning everything about this evolutionary strategy of animals, we invite you to continue reading this article.
What is the Brumation
Let’s start this article unveiling what is the fart. Brumation, like hibernation, is a state of lethargging that some animals suffer usually in cold times. Precisely during the mits, the organism continues with its basic vital functions, but drastically decreases its metabolic activity To save energy. It is worth clarifying that the mists can also occur when there is a shortage of food, drought or some other adverse environmental condition.
As we mentioned, the animal’s metabolic activity decreases considerably. However, they continue to hydrate and, in some cases, they can feed during this state of lethargging. However, mits in the mists is not a general rule, since, precisely, during the winter the food and functions of the digestive system are also depressed, therefore digestion becomes practically impossible.
What animals buman
If you wonder what are the animals that make the mists, we must keep in mind that this state is typical of the Ectoterms or cold -blooded animalsthat is, those animals that are not able to regulate their body temperature, but rather depend on external heat sources such as the sun. Therefore, the mists are specific to reptiles and amphibians. In itself, the mists constitutes an adaptation that ectoterms animals acquired to survive cold and other environmental adversities. We recommend reading this other article about 10 cold blood animals so that you know several examples.
Now, the sites where animals pass the mists are not random. In general, when the decrease in daylight hours begin to notice, at the end of summer or early fall, animals begin to look for safe sites or shelters where to pass the mists. For example, aquatic animals usually buried at the bottom of the bodies of water, while terrestrial animals dig holes on Earth, take refuge under fallen logs or even under the leaf litter. A curious case is that of the common salamandra (Salamandra Salamandra) that its state of lethargging elapses under the ice plates of frozen water bodies. To end this section, we will list some examples of animals that bruman:
- Bermeja frog (Temporary frog): It is located in Europe and northern Asia. It is a terrestrial amphibian, but the state of mourning takes place in the water.
- Spurs toad (Cultripes Pelobates): Its distribution is limited to the Iberian Peninsula. It usually excavate holeos of great depth to take refuge during the migration.
- Chaco land turtle (Chelonoidis chilensis): He is native to the Chaco forest in South America. According to the subspecies or the intensity of the cold of the area that reside, they can dig more or less deep wells on the earth based on shrubs or under dense herbaceous vegetation.
- Red ears turtles (TRACHEMYS SCRIPTA ELEGANS): Also known as Galapago de Florida, inhabits the southern United States and northern Mexico. Being an aquatic species, during the mists it is buried in the mud of the body of water that inhabits.
- Pork snout snake (Heterodon Platihiros): It is in Mexico and the United States. During winter, witch in deep burrows or under tree trunks.
- Lizard overo or Argentine tegú (Salvator Merianae): He is native to Argentina. During the cold months, Bruman in burrows that they themselves build or that other animals have abandoned.
Difference between Brumation and Hibernation
Frequently the mists is confused with hibernation. Although both imply a Letargo status In organisms, it is not the same. Let’s see some here Differences between hibernation and mists:
- During the hibernation, animals cannot wake up from the state of lethargy, while in the mourning, if the thermal conditions are modified, animals can leave that state.
- In hibernation animals survive from the nutritional reserves they have stored before starting the lethargy. The same does not happen in the mists, since animals can wake up to ingest water and, in some cases, food.
- Hibernation occurs in mammals while the mists occur in reptiles and amphibians.
