Species introduction: a commented synthesis

Abstract

In this review, some aspects of species introduction and transference into different environment, giving emphasis to the historical background, the process and the way in which the species were introduced, as well as some examples of impacts that this practice may cause to native communities are presented and discussed. Since man quit being nomad, he started a trace of species movement that stamp civilizations in all ecosystems, modifying the species natural distribution. At the moment, with the increasing demand for food and the facilities provided by the transportation means, this practice has become even more exacerbate, increasing the risks of species disappearance and extinction.
