Application of the Socio-Economic Impact Classification for Alien Taxa (SEICAT) to a global assessment of alien bird impacts

Evans, Thomas ; Blackburn, Tim M. ; Jeschke, Jonathan M. ; Probert, Anna F. ; Bacher, Sven

In: NeoBiota, 2020, vol. 62, p. 123–142

We use a recently proposed framework, the Socio-Economic Impact Classification for Alien Taxa (SEICAT) to undertake the first global assessment of the impacts of alien birds on human well-being. A review of the published literature and online resources was undertaken to collate information on the reported socio-economic impacts of 415 bird species with self-sustaining alien populations...

Projecting the continental accumulation of alien species through to 2050

Seebens, Hanno ; Bacher, Sven ; Blackburn, Tim M. ; Capinha, César ; Dawson, Wayne ; Dullinger, Stefan ; Genovesi, Piero ; Hulme, Philip E. ; Kleunen, Mark ; Kühn, Ingolf ; Jeschke, Jonathan M. ; Lenzner, Bernd ; Liebhold, Andrew M. ; Pattison, Zarah ; Pergl, Jan ; Pyšek, Petr ; Winter, Marten ; Essl, Franz

In: Global Change Biology, 2020, p. gcb.15333

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...

Scientists’ warning on invasive alien species

Pyšek, Petr ; Hulme, Philip E. ; Simberloff, Dan ; Bacher, Sven ; Blackburn, Tim M. ; Carlton, James T. ; Dawson, Wayne ; Essl, Franz ; Foxcroft, Llewellyn C. ; Genovesi, Piero ; Jeschke, Jonathan M. ; Kühn, Ingolf ; Liebhold, Andrew M. ; Mandrak, Nicholas E. ; Meyerson, Laura A. ; Pauchard, Aníbal ; Pergl, Jan ; Roy, Helen E. ; Seebens, Hanno ; Kleunen, Mark ; Vilà, Montserrat ; Wingfield, Michael J. ; Richardson, David M.

In: Biological Reviews, 2020, p. brv.12627

Biological invasions are a global consequence of an increasingly connected world and the rise in human population size. The numbers of invasive alien species – the subset of alien species that spread widely in areas where they are not native, affecting the environment or human livelihoods – are increasing. Synergies with other global changes are exacerbating current invasions and...

InvasiBES: Understanding and managing the impacts of Invasive alien species on Biodiversity and Ecosystem Services

Gallardo, Belinda ; Bacher, Sven ; Bradley, Bethany ; Comín, Francisco A. ; Gallien, Laure ; Jeschke, Jonathan M. ; Sorte, Cascade J. B. ; Vilà, Montserrat

In: NeoBiota, 2019, vol. 50, p. 109–122

Invasive Alien Species (IAS) are amongst the most significant drivers of species extinction and ecosystem degradation, causing negative impacts on ecosystem services and human well-being. InvasiBES, a project funded by BiodivERsA-Belmont Forum for 2019–2021, will use data and models across scales, habitats and species to understand and anticipate the multi-faceted impacts of IAS and to...

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 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...

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...

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...
