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...

A vision for global monitoring of biological invasions

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...

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...

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,...

Comparing impacts of alien plants and animals in Europe using a standard scoring system

Kumschick, Sabrina ; Bacher, Sven ; Evans, Thomas ; Marková, Zuzana ; Pergl, Jan ; Pyšek, Petr ; Vaes-Petignat, Sibylle ; Veer, Gabriel van der ; Vilà, Montserrat ; Nentwig, Wolfgang

In: Journal of Applied Ecology, 2015, vol. 52, no. 3, p. 552–561

Alien species can change the recipient environment in various ways, and some of them cause considerable damage. Understanding such impacts is crucial to direct management actions. This study addresses the following questions: Is it possible to quantify impact across higher taxa in a comparative manner? Do impacts differ between taxonomic groups? How are environmental and socio-economic impacts...

Explaining the variation in impacts of non-native plants on local-scale species richness: the role of phylogenetic relatedness

Vilà, Montserrat ; Rohr, Rudolf P. ; Espinar, José L. ; Hulme, Philip E. ; Pergl, Jan ; Roux, Johannes J. Le ; Schaffner, Urs ; Pyšek, Petr

In: Global Ecology and Biogeography, 2014, p. -

Aim: To assess how the magnitude of impacts of non-native plants on species richness of resident plants and animals varies in relation to the traits and phylogenetic position of the non-native as well as characteristics of the invaded site.Location: Global.Methods: Meta-analysis and phylogenetic regressions based on 216 studies were used to examine the effects of 96 non-native plant species on...

Which factors affect the success or failure of eradication campaigns against alien species?

Pluess, Therese ; Jarošík, Vojtěch ; Pyšek, Petr ; Cannon, Ray ; Pergl, Jan ; Breukers, Annemarie ; Bacher, Sven

In: PLoS ONE, 2012, vol. 7, no. 10, p. e48157

Although issues related to the management of invasive alien species are receiving increasing attention, little is known about which factors affect the likelihood of success of management measures. We applied two data mining techniques, classification trees and boosted trees, to identify factors that relate to the success of management campaigns aimed at eradicating invasive alien invertebrates,...

When are eradication campaigns successful? A test of common assumptions

Pluess, Therese ; Cannon, Ray ; Jarošík, Vojtěch ; Pergl, Jan ; Pyšek, Petr ; Bacher, Sven

In: Biological Invasions, 2012, vol. 14, no. 7, p. 1365-1378

Eradication aims at eliminating populations of alien organisms from an area. Since not all eradications are successful, several factors have been proposed in the literature (mainly by referring to case studies) to be crucial for eradication success, such as infestation size or reaction time. To our knowledge, however, no study has statistically evaluated which factors affect eradication...
