摘要: Alien species can represent a threat to several ecosystems because they alter relationships and ecosystem function. In Italy, Acacia saligna is major invader it forms dense stands in coastal environments. We analyze the impact of A. Italian Mediterranean dune systems. randomly sampled vegetation investigated its floristic composition with ordination techniques. compared richness invaded non-invaded plots rarefaction curves analyzed frequency focal ruderal species. scrub (habitats 2250* 2260) Pinus wood (habitat 2270*) particularly prevalent sunny areas habitat 2270*. observed an increase decrease suggest that more open disturbed are prone invasion.
