TL;DR: In this paper, the authors present a global meta-analysis of 199 articles reporting 1041 field studies that in total describe the impacts of 135 alien plant taxa on resident species, communities and ecosystems.

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 shown that there is no universal measure of impact and the pattern observed depends on the ecological measure examined, and some species traits, especially life form, stature and pollination syndrome, may provide a means to predict impact, regardless of the particular habitat and geographical region invaded.

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: A complete list of all alien taxa ever recorded in the flora of the Czech Republic is presented as an update of the original checklist published in 2002 as mentioned in this paper, which consists of 1454 taxa listed with information on their taxonomic position, life history, geographic origin, mode of origin, distinguishing anecophyte and hybrid, invasive status (casual; naturalized but not invasive; invasive), residence time status (archaeophyte vs neophyte), mode of introduction into the country (accidental, deliberate), and date of the first record.
