One century of crayfish invasions

The red swamp crayfish (Procambarus clarkii), native to the southern United States and north-eastern Mexico, is currently the most widely distributed crayfish globally, as well as one of the invasive species with most devastating impacts on freshwater ecosystems. Reconstructing the introduction routes of invasive species and identifying the motivations that have led to those movements is necessary to accurately reduce the likelihood of further introductions. In this study, the temporal...

Global meta-analysis of the impacts of terrestrial invertebrate invaders on species, communities and ecosystems

Terrestrial invertebrates comprise a large proportion of alien species worldwide, yet a quantitative global synthesis of their effects on native species and ecosystems has not been explored. In this study a meta-analysis was conducted to examine the ecological impacts of terrestrial invertebrate invaders.

Waterbirds as vectors for alien species

The importance of waterbirds as vectors of aliens has been recognized since Darwin's time, yet research by pioneers has been forgotten during the development of modern invasion biology, which tends to overlook this means of dispersal. Waterbirds are ignored in databases of alien species and invasion pathways, making management and prevention of invasions more difficult. This article summarizes studies that provide empirical evidence for the dispersal of alien plants and invertebrates by...

Guidelines for classifying Alien Taxa

A comprehensive framework and guidelines for implementing a recently developed method for classifying alien taxa is presented.
