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...

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. U. ; Winte, Marten ; Genovesi, Piero ; Bacher, Sven

In: PLoS Biol, 2014, vol. 12, no. 5, p. e1001850

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,...

Which taxa are alien? Criteria, applications, and uncertainties

Essl, Franz ; Bacher, Sven ; Genovesi, Piero ; Hulme, Philip E. ; Jeschke, Jonathan M. ; Katsanevakis, Stelios ; Kowarik, Ingo ; Kühn, Ingolf ; Pyšek, Petr ; Rabitsch, Wolfgang ; Schindler, Stefan ; Kleunen, Mark van ; Vilà, Montserrat ; Wilson, John R. U. ; Richardson, David M.

In: BioScience, 2018, vol. 68, no. 7, p. 496–509

Human activities such as the transport of species to new regions and modifications of the environment are increasingly reshaping the distribution of biota. Accordingly, developing robust, repeatable, and consistent definitions of alien species that serve scientific and policy purposes has become of prime importance. We provide a set of classification criteria that are widely applicable across...

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

In: BioScience, 2019, vol. 69, no. 11, p. 908–919

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...

Crossing Frontiers in Tackling Pathways of Biological Invasions

U.

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,...

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...

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...

A vision for global monitoring of biological invasions

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...

In: Proceedings of the National Academy of Sciences of the United States of America, 2010, vol. 107, no. 27, p. 12157-12162

The accelerating rates of international trade, travel, and transport in the latter half of the twentieth century have led to the progressive mixing of biota from across the world and the number of species introduced to new regions continues to increase. The importance of biogeographic, climatic, economic, and demographic factors as drivers of this trend is increasingly being realized but as yet...
