Protected areas are increasingly threatened by biological invasions, especially in tropical Asia where extensive areas of natural habitats have been c...

Interspecific competition is a recognized but under-studied mechanism by which invasive species affect native fauna. We experimentally reduced populat...

Key questions in invasion biology include where will a non-indigenous species (NIS) establish, and how will it affect biodiversity? Scientists have ad...

Plant nutrition (bottom-up effects) impacts a plant's ability to withstand herbivory (top-down effects) and influences phytophagous insect fecundity. ...

Restoration of habitats invaded by non-native plants should include both the removal of invasive plants and re-establishment of native plant communiti...

Wetlands in urban regions are subjected to a wide variety of anthropogenic disturbances, many of which may promote invasions of exotic plant species. ...

Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by t...

Deserts are one of the least invaded ecosystems by plants, possibly due to naturally low levels of soil nitrogen. Increased levels of soil nitrogen ca...

Invasive predators can dramatically alter ecosystems through both direct predation and indirect effects such as tropic cascades. However, most example...

The global pet trade provides a pathway for introduced species to invade new environments. Most studies use trade data as an indirect proxy for propag...
