Abstract
Con el tiempo la vegetación sufre cambios tanto en su composición florística como en la importancia relativa de sus especies. Estos cambios pueden ser fenológicos debido a la estacionalidad, en forma de fluctuaciones debido a variaciones ambientales interanuales, cambios cíclicos cuando ocurre una secuencia recurrente de poblaciones específicas en un sitio determinado, o bien cambios unidereccionales en la vegetación, cuyas etapas constituyen la sucesión vegetal. A lo largo de la historia de la ciencia de la vegetación, se han propuesto distintos modelos y teorías que han tratado de explicar la dinámica y los procesos que ocurren durante la sucesión vegetal. El objetivo de este trabajo es presentar una breve revisión de los mismos.
Vegetation undergoes changes along time in its floristical composition as well as in the relative importance of its species. These may be phenological changes along seasons, fluctuations due to interannual environmental variation, cyclic changes when there is a recurrent sequence of specific populations in a site, and unidirectional changes in vegetation, which are known as plant succession. Along the history of vegetation science different models and theories have been proposed in order to explain the dynamics of such complex systems and the processes which occur during plant succession. The object of this paper is to offer a brief review of them.
