As the climate warms, animals change their forms, but which animals are the most special?

Polar bears, birds, arctic foxes, grey forest owls, and mammals are special and change their form depending on the weather.

Polar bears, penguins, birds, amphibians, rodents, these animals are relatively special, and the impact on them is very great.

The change of weather directly affects the life of animals and animals. Some animals with keen senses can often detect changes in the weather in time and prepare in advance.

Ants move, heavy rain. Before heavy rains, the moisture absorbed by the soil increases due to the increase in air humidity, so the ant nests built in the soil become damp. To avoid flooding, ants tend to move before heavy rains.

The loaches are rolling, and the rain is coming. On sunny days, the water contains a lot of oxygen, and loaches live quietly underwater. Before the heavy rain arrives, the oxygen content in the water decreases, and the loaches feel difficult to breathe, so they keep tumbling up and down in the water.

Spiders build webs, and it will clear after a long rain. It rained for a long time, and the spider's web was broken by the rain. But when the weather is about to clear up, the air is no longer dull, and all kinds of small flying insects become very active, and the spiders begin to build webs to prey on flying insects.

The bees are out of the nest and the weather is fine. After a long period of rain and sunshine, the air pressure begins to rise, the air humidity gradually decreases, and pollen appears on the stamens of plants, and bees go out to collect nectar.

The frog crooked, and the rain was coming. On a clear night, the air is fresh, and all kinds of insects come out to move, and the frogs can catch food and feel refreshed, so the song is loud. Heavy rain is approaching, the air is dull, and the frogs are irritable and often have a low chirp.

Some migrate, some hibernate, etc.

The relationship between animals and their living environment is intimate. Weather has a direct impact on the lives of animals. Some animals with keen senses can often detect changes in the weather in time and accurately, and prepare for life in advance.

Earthworms, like earthworms, live in moist soil sacs rich in humus, wriggle their bodies through the combination of muscles and bristles, and feed on dead leaves, rotten roots, and other organic matter of plants. Earthworms cannot maintain a constant body temperature, so they can only live in the deep layers of the soil sac where the temperature does not change too much.

Before heavy rains, the moisture absorbed by the soil increases due to the increase in humidity in the air, so the ant nests built in the soil become damp, and the ants often move before the heavy rain to avoid flooding. There is also a saying that it will rain sooner or later when ants move.

Animals that belong to ectotherms are fish, frogs, snakes, chameleons, lizards, crocodiles, and other animals.

Ectotherms (commonly known as cold-blooded animals) are animals other than mammals and birds, and most of the animals on Earth are ectotherms. Because there is no mechanism for regulating body temperature in the animal's body, the ectothermic animal can only rely on its own behavior to regulate the emission of body heat or absorb heat from the external environment to increase its own body temperature.

When the temperature of the external environment rises, the metabolic rate of the animal increases, and the body temperature gradually rises, and they passively leave the unfavorable environment; When the temperature of the external environment decreases, the metabolic rate of the animal also decreases, and the body temperature gradually decreases. So they either move to the sun to warm up their body temperature, or burrow into the ground or burrows to hibernate, or swim to warm waters, or hibernate in summer.

Advantages of variable temperature:

It can survive under conditions where the external environment or food supply changes greatly. Because they require less energy to maintain body temperature and physiology. The energy from food can be used for more growth.

As a result, ectotherms are more efficient at converting food into body growth than homeotherms.

Although the number of ectotherms in the same environment can be dozens of times that of homeotherms, the adaptability of ectotherms to the environment is weaker than that of homeotherms. Homeothermic animals, for example, can overcome the adverse factors of the environment and have a longer time and a wide range of space to obtain food.

In the context of climate warming, more and more animals have modified their bodies in order to adapt to the current climate, and in Darwin's theory of evolution, such behavior is evolution. <>

First, what kind of animal form has changed.

This time, the article was published by an Australian bird expert, who said that in the course of the investigation in recent years. He noticed that many of the birds were starting to show some abnormalities, such as their claws and ears starting to grow larger. Compared to their previous body shape, they have changed drastically, and he believes that the main reason for this is that the rise in temperature has forced them to change their body structure so that they can emit more heat.

So far, the data he has counted shows that most birds have changed by 4 to 10 percent. <>

Second, how to view such changes.

In this case, we must first recognize that the impact of global temperature rise on the ecological environment is irreversible, and once these animals grow up to adapt to high temperatures, it may be difficult to adapt to future temperature drops. After all, it takes hundreds of thousands of years for a species to evolve. <>

Third, how should we solve such a situation?

At present, all countries in the world are very concerned about the problem of global temperature rise, but all countries do not want to come up with practical solutions. This is especially evident in the developed countries of the West, mainly because the most fundamental cause of global warming is carbon dioxide emissions. And carbon dioxide emissions also mean the progress of industrialization, if human beings give up industrialization, then probably all human beings will not agree.

So from a certain point of view, the only way to change this situation is to accelerate industrialization, thereby changing the existing energy structure.

Warming causes some animals to begin to deform, and these categories of animals change the most: scientists have found that birds are changing the most due to climate change! The length of the tail of the technique increases, the size of the wings of bats increases in warm climates, when the weather is too hot, birds and mammals use the same and ears respectively to dissipate heat, as the weather changes, they may die from overheating, the rump is not covered by feathers is an important part of heat exchange, and the ears, tail and legs of mammals, if they are not covered by fur are also the same.

Pandas, polar bears, penguins, crocodiles and snakes are all animals that vary greatly, especially snakes.

Bats, black-eyed rushes, masked shrews, shrews, parrots. These crops have changed a lot, some have no ears and become larger, and some animals have longer beaks.

Warm-blooded animals are morphing, their beaks, limbs, and ears getting larger and better at regulating their body temperature. Among them, birds are the most varied, and studies have shown a link between increased beak size and short-term temperature extremes in cold environments.

ectotherms. It is characterized by being able to regulate the dissipation of body heat or absorb heat from the external environment to increase one's body temperature by only regulating one's own behavior.

Animals whose body temperature changes with the change of the outside temperature are called ectotherms; Except for birds and mammals.

Except for the rest of the animals, they are ectotherms. Their body temperature changes with the environment, which does not mean that they must not control their body temperature, they can change their body temperature by looking for a cool or warm environment, but they cannot directly control their body temperature, that is, they lack the physiological function to maintain a certain body temperature.

Because ectotherms do not need to use their own energy to warm or cool down, compared to homeothermic animals.

Ectotherms of the same weight only need 1 10-1 3 energy to survive, and therefore only need relatively little noisy food. Because they are more likely to accumulate enough energy, ectotherms also have a shorter breeding period.
