Alien species can change the recipient environment in various ways, and some of them cause considerable damage. Understanding such impacts is crucial to direct management actions. This study addresses the following questions: Is it possible to quantify impact across higher taxa in a comparative manner? Do impacts differ between taxonomic groups? How are environmental and socio-economic impacts...

Aim Human activities have led to the spread and establishment of increasing numbers of non-native species. Here we assess whether non-native plant and vertebrate species have affected species compositions within and across Europe and North America. We also assess the effects of intra-continental species exchange using the example of vertebrates.Location European countries and North America...
