Abstract/Summary

Ecological impacts of terrestrial invasive plants and vertebrates in Europe. The impact of introduced species is one of the least studied aspects of the ecology of biological invasions especially in Europe. Most studies have focussed on those species with an economic impact. We have reviewed the literature on the effects of invasive plant and terrestrial vertebrate species on native species and receptive ecosystems in Europe. Invasive plants can interfere by competition or allelopathy with native plants. At the community level, the most studied impact is that of a decrease of species diversity and the local displacement of some of them. Alien plants can also interfere at high trophic levels such as by competition for pollinators. At the ecosystem level they can change nutrient cycling (i.e. N fixing species), soil water availability and alter natural disturbance regimes. For invasive vertebrates, if they occupy the same ecological niche as a native species, one species may interfere with the other. Usually this happens by competition for food or other resources, via direct predation or transfer of pathogens. They can also considerably alter the vegetation structure and succession.
