We have all heard the term “fauna”. What is this concept? Now we will understand in detail.
Definition
So, fauna ... What is this term? Large explanatory dictionary of the modern Russian language D.N. Ushakova claims that this is the animal world, all kinds of animals inherent in a given area or geological era. And if you need to describe the fauna of a particular region, the mainland, the island, then domestic animals (that is, those that a person artificially brought into the area or cultivated) are not taken into account. Although in themselves they also belong to this totality.
The same applies to insects (they are also representatives of the fauna), because often a person arriving in a new territory for the purpose of development or simply traveling, not knowing, brings with him adult insects disguised in clothing or luggage, or their larvae, diluting or even violating thereby, the “backbone” of the animal world historically formed in this area. But with this method of distribution, not every type of insect has a chance to survive in a foreign area, if only because of the inappropriate climate.
Aggregates
Based on geographical criteria, biologists united representatives of the fauna into groups that also connected among themselves on the basis of historical interconnection and common biogeocenoses (ecosystems). As a result, the fauna world was clearly classified according to the zonal continental feature. In scientific circles, this feature is called geographical. But the animal kingdom of a single continent and a certain latitude cannot be considered as a single cluster. Therefore, it was necessary to extend the chain of division of animals: ichthyofauna (fish), avifauna (birds), entomofauna (insects).
But this "sorting" did not end there. The ecological nature of the species is the next step in the classification of fauna, reflecting the lifestyle and behavioral characteristics of each animal species. For example, only those who know how to swim live in flooded territories and in marshy areas, and animals that are able to jump from tree to tree and adapted to life on such plants dominate in subtropical and tropical forests.
So, the fauna ... What is it? What is she like? More on this later.
Flora and fauna: what is it?
It is very important in the study of the fauna of a particular area is to clarify the methods and ways of immigrating species into the local group. This, as has already been said, is to some extent blamed on humans, since the intensive development of intercontinental routes of sea and airliners jeopardizes the originality and authenticity of the fauna of different ecosystems.
All the described methods and methods of classification and gradation, as well as the accounting and conservation of diversity in compliance with endemism, apply equally to the flora. And what does this concept mean ? Now let's figure it out. This is a collection of plants growing in a certain area.
By the way, man is also a representative of the fauna, although he calls himself the peak of evolution, the crown of creation of nature. This is all due to the volume of the brain. He is incomparably greater than the intelligence of any other living being. Possessing the gift of speech and a brain that allows you to think and create - this is what distinguishes man from animals.
In general, human activities on Earth can be called creative. But often successes in this are dizzy and cause a surge of ambition and vanity, making it possible to think that fauna is the property of man, given to him by Heaven. And, adhering to this opinion, for thousands of years man has tamed, ennobled, cultivated many species of animals that are either helpers or entertainment or food for him.
Conclusion
Now you know such things as flora and fauna. What are these terms, we examined in detail. It is safe to say that representatives of these classes fill our world. It is thanks to the flora and fauna that our planet is called living, because all animals, birds and plants create the biosphere of the Earth.
