Biological invasions have steadily increased over recent centuries. However, we still lack a clear expectation about future trends in alien species numbers. In particular, we do not know whether alien species will continue to accumulate in regional floras and faunas, or whether the pace of accumulation will decrease due to the depletion of native source pools. Here, we apply a new model to...

A conceptual framework for range-expanding species that track human-induced environmental change

Essl, Franz ; Dullinger, Stefan ; Genovesi, Piero ; Hulme, Philip E ; Jeschke, Jonathan M ; Katsanevakis, Stelios ; Kühn, Ingolf ; Lenzner, Bernd ; Pauchard, Aníbal ; Pyšek, Petr ; Rabitsch, Wolfgang ; Richardson, David M ; Seebens, Hanno ; van Kleunen, Mark ; van der Putten, Wim H ; Vilà, Montserrat ; Bacher, Sven

For many species, human-induced environmental changes are important indirect drivers of range expansion into new regions. We argue that it is important to distinguish the range dynamics of such species from those that occur without, or with less clear, involvement of human-induced environmental changes. We elucidate the salient features of the rapid increase in the number of species whose...

Scientific and normative foundations for the valuation of alien-species impacts: thirteen core principles

Essl, Franz ; Hulme, Philip E. ; Jeschke, Jonathan M. ; Keller, Reuben ; Pyšek, Petr ; Richardson, David M. ; Saul, Wolf-Christian ; Bacher, Sven ; Dullinger, Stefan ; Estévez, Rodrigo A. ; Kueffer, Christoph ; Roy, Helen E. ; Seebens, Hanno ; Rabitsch, Wolfgang

In: BioScience, 2017, vol. 67, no. 2, p. 166–178

Biological invasions cause many impacts that differ widely in how they are perceived. We argue that many conflicts in the valuation of the impacts of alien species are attributable to differences in the framing of the issue and implicit assumptions—such conflicts are often not acknowledged. We present 13 principles that can help guide valuation and therefore inform the management of alien...

Biological Flora of the British Isles: Ambrosia artemisiifolia

Essl, Franz ; Biró, Krisztina ; Brandes, Dietmar ; Broennimann, Olivier ; Bullock, James M. ; Chapman, Daniel S. ; Chauvel, Bruno ; Dullinger, Stefan ; Fumanal, Boris ; Guisan, Antoine ; Karrer, Gerhard ; Kazinczi, Gabriella ; Kueffer, Christoph ; Laitung, Beryl ; Lavoie, Claude ; Leitner, Michael ; Mang, Thomas ; Moser, Dietmar ; Müller-Schärer, Heinz ; Petitpierre, Blaise ; Richter, Robert ; Schaffner, Urs ; Smith, Matt ; Starfinger, Uwe ; Vautard, Robert ; Vogl, Gero ; Lippe, Moritz von der ; Follak, Swen

In: Journal of Ecology, 2015, vol. 103, no. 4, p. 1069–1098

This account presents information on all aspects of the biology of Ambrosia artemisiifolia L. (Common ragweed) that are relevant to understanding its ecology. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral...
