It is proposed that the term ‘invasive’ should be used without any inference to environmental or economic impact, and terms like ‘pests’ and ‘weeds’ are suitable labels for the 50–80% of invaders that have harmful effects.
A proposed unified framework for biological invasions.
Ecological impacts of invasive alien plants: a meta-analysis of their effects on species, communities and ecosystems.
Overall, alien species impacts are heterogeneous and not unidirectional even within particular impact types, and by the time changes in nutrient cycling are detected, major impacts on plant species and communities are likely to have already occurred.

Recommendations are outlined on how to deal with the issue of plant invasions in standard floras with the aim of contributing to a better understanding between taxonomists and ecologists and allowing more detailed comparative analyses of alien floras of various regions of the world.
Impacts of biological invasions: what's what and the way forward.
Catalogue of alien plants of the Czech Republic.
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, with 44 taxa on the list that are reported in the present study for the first time as aliens introduced to the CzechRepublic or escaped from cultivation.
Plant invasions: merging the concepts of species invasiveness and community invasibility
Concepts, hypotheses and theories reviewed here can be linked to the naturalization-invasion continuum concept, which relates invasion processes with a sequence of environmental and biotic barriers that an introduced species must negotiate to become casual, naturalized and invasive.
Riparian vegetation: degradation, alien plant invasions, and restoration prospects
Rivers are conduits for materials and energy; this, the frequent and intense disturbances that these systems experience, and their narrow, linear nature, create problems for conservation of…
A global assessment of invasive plant impacts on resident species, communities and ecosystems: the interaction of impact measures, invading species' traits and environment
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.
Traits Associated with Invasiveness in Alien Plants: Where Do we Stand?
Any organism must be equipped for life in a given environment, otherwise it will die. The fundamental question is how well does an organism need to be “equipped”, or what syndrome of traits must it…
