The word fauna is derived from the Latin "Faunus" which has been translated as Faun, who was the Roman god responsible for the fertilization of animals and their proliferation, although it is also believed that Fauna was the name of the Roman goddess of the earth and the fertility of all the species that were on it. The fauna is considered today as the set of animals that originate or own a zone or geographical region determined in this field includes all species that exist in that specific space also should be aware that these species they also belong to a geological periodBeing able to be found in a given ecological system, if an alteration occurs in the fauna of an ecosystem, it can be altered, causing serious damage to it or to the animal species itself, since animals are vulnerable when changes occur in their normal habitat.
The development of the fauna of a region depends on both biotic factors and abiotic factors, so that they can survive and evolve properly, since what determines the emergence of the animal species is the environment to which they are exposed, taking into account factors such as the climate., temperature, the existence of water, in addition to the presence of other competitive or predatory species.
There are different types of fauna and this depends on their origin, on the one hand there are those that are called autochthonous, and they are known in this way because they are native to a specific area or simply because some natural phenomenon that has occurred in the The land took them there, without the intervention of human beings in their location, being able to adapt themselves better to the environment in which they live. And otherwise there are the so-called exotic or foreign species, which are those types of animals that were introduced by humans into an ecosystem to which they did not initially belong. And finally the invasive species, in which they themselves have decided to change their habitat looking for an improvement in it.
In another type of classification it can be said that they are wild (those found in nature and act according to their instincts) and domestic (in which man has intervened in their upbringing so that over time they lose their character. wild).
