Roy, Helen E. ; Rabitsch, Wolfgang ; Scalera, Riccardo ; Stewart, Alan ; Gallardo, Belinda ; Genovesi, Piero ; Essl, Franz ; Adriaens, Tim ; Bacher, Sven ; Booy, Olaf ; Branquart, Etienne ; Brunel, Sarah ; Copp, Gordon Howard ; Dean, Hannah ; D?hondt, Bram ; Josefsson, Melanie ; Kenis, Marc ; Kettunen, Marianne ; Linnamagi, Merike ; Lucy, Frances ; Martinou, Angeliki ; Moore, Niall ; Nentwig, Wolfgang ; Nieto, Ana ; Pergl, Jan ; Peyton, Jodey ; Roques, Alain ; Schindler, Stefan ; Schönrogge, Karsten ; Solarz, Wojciech ; Stebbing, Paul D. ; Trichkova, Teodora ; Vanderhoeven, Sonia ; Valkenburg, Johan van ; Zenetos, Argyro

Biological invasions are a threat to biodiversity, society and the economy. There is an urgent need to provide evidence-based assessments of the risks posed by invasive alien species (IAS) to prioritize action. Risk assessments underpin IAS policies in many ways: informing legislation; providing justification of restrictions in trade or consumer activities; prioritizing surveillance and rapid...

A vision for global monitoring of biological invasions

Pyšek, Petr ; Jeschke, Jonathan M. ; Blackburn, Tim M. ; Bacher, Sven ; Capinha, César ; Costello, Mark J. ; Fernández, Miguel ; Gregory, Richard D. ; Hobern, Donald ; Hui, Cang ; Jetz, Walter ; Kumschick, Sabrina ; McGrannachan, Chris ; Pergl, Jan ; Roy, Helen E. ; Scalera, Riccardo ; Squires, Zoe E. ; R.U.Wilson, John ; Winter, Marten ; Genovesi, Piero ; McGeoch, Melodie A.

In: Biological Conservation, 2017, vol. 213, no. Part B, p. 295–308

Managing biological invasions relies on good global coverage of species distributions. Accurate information on alien species distributions, obtained from international policy and cross-border co-operation, is required to evaluate trans-boundary and trading partnership risks. However, a standardized approach for systematically monitoring alien species and tracking biological invasions is still...

Socio-economic impact classification of alien taxa (SEICAT)

Bacher, Sven ; Blackburn, Tim M. ; Essl, Franz ; Genovesi, Piero ; Heikkilä, Jaakko ; Jeschke, Jonathan M. ; Jones, Glyn ; Keller, Reuben ; Kenis, Marc ; Kueffer, Christoph ; Martinou, Angeliki F. ; Nentwig, Wolfgang ; Pergl, Jan ; Pyšek, Petr ; Rabitsch, Wolfgang ; Richardson, David M. ; Roy, Helen E. ; Saul, Wolf-Christian ; Scalera, Riccardo ; Vilà, Montserrat ; Wilson, John R. U. ; Kumschick, Sabrina

In: Methods in Ecology and Evolution, 2017, p. -

Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa...

Troubling travellers: are ecologically harmful alien species associated with particular introduction pathways?

Pergl, Jan ; Pyšek, Petr ; Bacher, Sven ; Essl, Franz ; Genovesi, Piero ; Harrower, Colin A. ; Hulme, Philip E. ; Jeschke, Jonathan M. ; Kenis, Marc ; Kühn, Ingolf ; Perglová, Irena ; Rabitsch, Wolfgang ; Roques, Alain ; Roy, David B. ; Roy, Helen E. ; Vilà, Montserrat ; Winter, Marten ; Nentwig, Wolfgang

In: NeoBiota, 2017, vol. 32, p. 1–20

Prioritization of introduction pathways is seen as an important component of the management of biological invasions. We address whether established alien plants, mammals, freshwater fish and terrestrial invertebrates with known ecological impacts are associated with particular introduction pathways (release, escape, contaminant, stowaway, corridor and unaided). We used the information from...

Framework and guidelines for implementing the proposed IUCN Environmental Impact Classification for Alien Taxa (EICAT)

Hawkins, Charlotte L. ; Bacher, Sven ; Essl, Franz ; Hulme, Philip E. ; Jeschke, Jonathan M. ; Kühn, Ingolf ; Kumschick, Sabrina ; Nentwig, Wolfgang ; Pergl, Jan ; Pyšek, Petr ; Rabitsch, Wolfgang ; Richardson, David M. ; Vilà, Montserrat ; Wilson, John R.U. ; Genovesi, Piero ; Blackburn, Tim M.

In: Diversity and Distributions, 2015, vol. 21, no. 11, p. 1360–1363

Recently, Blackburn et al. (2014) developed a simple, objective and transparent method for classifying alien taxa in terms of the magnitude of their detrimental environmental impacts in recipient areas. Here, we present a comprehensive framework and guidelines for implementing this method, which we term the Environmental Impact Classification for Alien Taxa, or EICAT. We detail criteria for...

Crossing Frontiers in Tackling Pathways of Biological Invasions

Essl, Franz ; Bacher, Sven ; Blackburn, Tim M. ; Booy, Olaf ; Brundu, Giuseppe ; Brunel, Sarah ; Cardoso, Ana-Cristina ; Eschen, René ; Gallardo, Belinda ; Galil, Bella ; García-Berthou, Emili ; Genovesi, Piero ; Groom, Quentin ; Harrower, Colin ; Hulme, Philip E. ; Katsanevakis, Stelios ; Kenis, Marc ; Kühn, Ingolf ; Kumschick, Sabrina ; Martinou, Angeliki F. ; Nentwig, Wolfgang ; O'Flynn, Colette ; Pagad, Shyama ; Pergl, Jan ; Pyšek, Petr ; Rabitsch, Wolfgang ; Richardson, David M. ; Roques, Alain ; Roy, Helen E. ; Scalera, Riccardo ; Schindler, Stefan ; Seebens, Hanno ; Vanderhoeven, Sonia ; Vilà, Montserrat ; Wilson, John R. U.

In: BioScience, 2015, vol. 65, no. 8, p. 769–782

Substantial progress has been made in understanding how pathways underlie and mediate biological invasions. However, key features of their role in invasions remain poorly understood, available knowledge is widely scattered, and major frontiers in research and management are insufficiently characterized. We review the state of the art, highlight recent advances, identify pitfalls and constraints,...

Ecological impacts of alien species: quantification, scope, caveats, and recommendations

Kumschick, Sabrina ; Gaertner, Mirijam ; Vilà, Montserrat ; Essl, Franz ; Jeschke, Jonathan M. ; Pyšek, Petr ; Ricciardi, Anthony ; Bacher, Sven ; Blackburn, Tim M. ; Dick, Jaimie T.A. ; Evans, Thomas ; Hulme, Philip E. ; Kühn, Ingolf ; Mrugała, Agata ; Pergl, Jan ; Rabitsch, Wolfgang ; Richardson, David M. ; Sendek, Agnieszka ; Winter, Marten

In: BioScience, 2015, vol. 65, no. 1, p. 55–63

Despite intensive research during the past decade on the effects of alien species, invasion science still lacks the capacity to accurately predict the impacts of those species and, therefore, to provide timely advice to managers on where limited resources should be allocated. This capacity has been limited partly by the context-dependent nature of ecological impacts, research highly skewed toward...

A unified classification of alien species based on the magnitude of their environmental impacts

Blackburn, Tim M. ; Essl, Franz ; Evans, Thomas ; Hulme, Philip E. ; Jeschke, Jonathan M. ; Kühn, Ingolf ; Kumschick, Sabrina ; Marková, Zuzana ; Mrugała, Agata ; Nentwig, Wolfgang ; Pergl, Jan ; Pyšek, Petr ; Rabitsch, Wolfgang ; Ricciardi, Anthony ; Richardson, David M. ; Sendek, Agnieszka ; Vilà, Montserrat ; Wilson, John R.

Species moved by human activities beyond the limits of their native geographic ranges into areas in which they do not naturally occur (termed aliens) can cause a broad range of significant changes to recipient ecosystems; however, their impacts vary greatly across species and the ecosystems into which they are introduced. There is therefore a critical need for a standardised method to evaluate,...
