There are terms that apply to two or more different areas of human activity. In most cases, they have a similar interpretation, the only difference is in the specifics. But there are those whose decoding is simply two polar concepts, and one of them is “introduction”. This word is familiar mainly to biologists and zoologists, and it also often appears in music. Well, let's take a look at two of his interpretations.
What is introduction in biology?
It’s worth starting with science, since it is in this industry that this term is more common. Moreover, it is heard not only among scientists, but also among schoolchildren, as well as among students, since it has a simple interpretation and is considered a very common phenomenon in nature.
From a biological point of view, introduction is the relocation of a certain species of animals or plants to another territory on which they did not previously live. This process can be specially organized or happen by chance. In other words, introduction is the process of introducing alien species that are not inherent in an extraneous ecosystem.
Adaptation
After a new species appears in a new territory, it goes through the process of acclimatization. This is necessary in order for the plant or animal to get used to the new habitat, adopt a new ecosystem, weather, soil, air, etc. There are species that do not even notice such changes and do not experience discomfort (for example, cockroaches). But certain living organisms are not always well acclimatized, some of them die under new conditions. Often introduced species drag a chain of biological changes in a new ecosystem. Because of them, a certain species of local fauna or flora changes or even dies out. In such cases, it is believed that the experiment ended with biological pollution.
Plant introduction
The people have mastered this practice for many centuries, and it cannot be said that it received success or failure. It will be more accurate to note that the result here is 50/50, that is, everything depends on the plant itself, as well as on the conditions in which it will have to move. Centuries-old practice has taught mankind some tricks in this matter. Firstly, you can not radically change the living conditions for the plant, that is, you cannot transplant a palm tree from the tropics to the tundra. For a transplant of a certain type, several similar conditions are needed - climate, soil, rainfall. And the second conclusion that people came to is the division of this process into two types: simple and complex.
Easy Transplant Method
The name speaks for itself. A simple introduction of plants is a transplant of those without any biological or chemical intervention to a new place. There are two ways to carry out a similar procedure. The first is that a preliminary experiment is carried out, its consequences are studied, and only then the necessary types of flora are resettled. The second way - a small batch of a certain breed of plant is induced, its reactions are studied, and if only they are positive, the process is brought to an end.
Complex plant transplant
In this case, biological developments and chemical experiments are used. Complex introduction is the breeding of new plant species whose properties will correspond to the new habitat. For a small number of representatives of a new breed, artificial ecosystems are often constructed in which climate, soil, irrigation and other living conditions are established, such as will be in a new place. In this case, the new breed either takes root, after which it is transported to other territories, or undergoes further changes.
Little help
By the way, the most striking example of plant introduction is potato and corn. These cultures were moved from America to Europe. Due to the fact that the plants were unpretentious, they not only took root in the new hemisphere, but also were able to adapt to various climatic zones: temperate, subtropical and tropical.
Animal introduction
This phenomenon is considered more common than the previous one, and all because animals, oddly enough, can walk. Of course, it’s unlikely that any of them will be able to swim across the Atlantic Ocean, but if it gets on a ship, then it becomes quite real. Thanks to the ancient ships around the world, rats spread. After all, few people know that their homeland is Asia. It was after the Crusades that these animals, together with the knights, loaded onto the ships and went to a new house - to Europe. And from there, together with the discoverers, on the same ships they moved to America.
If the introduction of animals is intentional, then we are most likely talking about livestock. Horned breeding is the prerogative of the highlanders, and the inhabitants of the valleys based herding on their experience.
In the field of art
Introduction to music is a kind of vast and complete introduction. It is performed as a brief initial part of a large work of complex shape. Often this introductory passage has an autonomous name, and it is likely that it can be performed independently. The introduction may be called the overture to the opera or the first scene, which follows immediately after the overture.
The dimensions and shapes of this small work do not have clear boundaries and requirements. It is only important that it tunes the listener to the mode and tonality in which the instrumental or choral composition will be performed.
Musical examples
There are such works where the term "introduction" is brought to the fore. This is done if the introduction is of particular importance for the further perception of the composition, it is especially beautiful and sets the viewer in the right mood. For example, consider the work of Pablo de Sarasate, Introduction and Tarantella.
The first part is calm, lingering and melodic, but it determines the tonality of the work and its mood. The second part is the dance itself. Tarantella is always energetic, fast and very rhythmic. Similar examples are found in the works of Frederic Chopin - “Introduction and Shiny Polonaise”, by Camille Saint-Saens - “Introduction and Rondo Capriccioso”, as well as many other composers.
