Do Habitats Show a Different Invasibility Pattern by Alien Plant Species? A Test on a Wetland Protected Area

摘要: Biological invasions are deemed to be the second most important global driver of biodiversity loss, right behind habitat destruction and fragmentation. In this study, we aimed at testing if community invasibility, defined as vulnerability invasion a community, could associated with characteristics given habitat, described by composition structure its native species. Based on probabilistic sampling alien flora occurring in temperate wetland Lake Doberdo (Friuli Venezia Giulia region, NE Italy) using null-model-based approach, observed occurrence Invasive Alien Species (IAS) within units was randomized habitats. While degree invasibility for each wetland, our null hypothesis postulated that habitats equally invaded IAS, IAS can spread homogeneously environment thanks their plasticity functional traits makes them able cope different ecological conditions. The obtained results comparing frequencies, abundance richness those model randomizations show that, all habitats, selective. Specifically, marked preference an intermediate disturbance level, high nutrients level medium-high light availability observed, while avoidance detected characterized lower levels or extreme conditions caused prolonged submersion. This method allows us provide useful information simple-to-run simulation management threat protected areas. Moreover, infer leading without environmental characteristic which is expensive operation terms time money.
