Role of Allelopathy During Invasion Process by Alien Invasive Plants in Terrestrial Ecosystems

摘要: Biological invasion is causing serious current biodiversity loss in different parts of the world and involves stages: introduction, establishment, naturalization, fast dispersion outside normal ranks. Invasion may cause a reduction abundance native species or elimination populations particular species. Exotic have to surpass biological filters get be invaded new habitat. Importance allelopathy process include release secondary chemical metabolites into surrounding environment inhibit seedling establishment other ecophysiological attributes biota. Temperature, drought, cold, association, feedback from soil microorganism can also adversely affect nutrient cycle, aspects that favor invading capacity exotic Environmental problems generated by become naturally protected sensitive areas, where climatic circumstances evolve shape global warming. The purpose this chapter highlight role during with special emphasis relationships between plants, microorganisms.
