Relict is a term that comes from the Latin word relictus, which in turn derives from the verb whinnying. The Royal Spanish Academy (RAE) acknowledges its use in the field of straight, although it does not provide a definition of the term.
What the RAE is the concept of relict goods or relict flow. These ideas are associated with what leaves a person when go dead. This relict patrimony is made up of the assets, obligations and rights that result from the death of an individual.
The relict flow can be divided into the full flow (includes both assets and liabilities of the deceased person) and the liquid flow (the resulting equity after deducting the debts). East heritage it can be the center of an inheritance or legacy.
The notion of relict is also used in the context of biology. Living beings whose distribution is bounded or that they managed to survive some natural phenomenon or human action.
There is talk of relict species, therefore, when the number of copies is in decline and limited to a small geographic space. This can be caused by the emergence of a new predator, a change in the climate, or the activity of the human being, among other reasons.
Relict species are distinguished by their scarce presence on the planet, unlike others, which abound, or those that simply enjoy the space that naturally corresponds to them. In addition to the aforementioned causes, a species can reach this point if the competition (a type of interspecific relationship) harms them, something that can occur in different ways and at various levels.
For the number of individuals of a species to decrease, it is not always necessary for another to use it as a basis for its diet, but certain changes in the environment generated by competitors can leave it without the necessary nutrients for its subsistence, or deprive it of the nutrients. means they used to take refuge from their natural predators. This is especially true in small or highly fragmented populations.
In this sense, it is called relict forest to the one that is a remnant of a much larger one that has lost much of its surface. To be classified as a relict, a comparison is made with some time in the past, which allows determining that Forest in question has regressed.
One of the most prominent examples of these vestiges of flora It is the Fray Jorge forest, located in the Chilean province of Coquimbo, more precisely in the Altos de Talinay, a cordon of hills. It is a space characterized by vegetation semi-desert (such as sclerophyllous and xerophilous scrub) and a Mediterranean climate. To the south it borders the Limarí River, while to the west is the Pacific Ocean.
The feature of this relict forest that most admires its visitors is that it is a true green spectacle in a rather desert area, which leads them to wonder how it is possible that they survive and how they got there in the first place. Some experts suggest that the origin of the flora of the Fray Jorge forest is mixed, found in ancestors diversified, southern and boreal areas of the center and south of the country.
Palmar de Ocoa is another well-known relict forest in Chile, located southeast of Quillota. Some of the Chilean palms (jubea chilensis) that live in it are three centuries old and grow very close to each other. For more than a hundred years, its various owners have been in charge of preserving it, and for this reason it is considered a sanctuary of conservation.
