TL;DR: In this paper, the authors used a database of 45,813 first records of 16,926 established alien species and showed that the annual rate of first records worldwide has increased during the last 200 years, with 37% of all first records reported most recently (1970-2014).

TL;DR: It is emphasised that global warming has enabled alien species to expand into regions in which they previously could not survive and reproduce and management practices regarding the occurrence of 'new' species could range from complete eradication to tolerance.

TL;DR: A framework is proposed to facilitate the comparative analysis of invasion pathways by a wide range of taxa in both terrestrial and aquatic ecosystems and helps identify existing gaps in current knowledge of pathways and highlight the limitations of existing legislation to manage introductions of alien species.

TL;DR: The effects caused by different insect invaders are reviewed according to their ecosystem roles, i.e. herbivores, predators, parasites, parasitoids and pollinators; the level of biological organisation at which they occur; and the direct and indirect mechanisms underlying these effects.
