- ItemOpen minded and open access : introducing NeoBiota, a new peer-reviewed journal of biological invasions(Pensoft, 2011) Kuhn, Ingolf; Kowarik, Ingo; Kollmann, Johannes; Starfinger, Uwe; Bacher, Sven; Blackburn, Tim M.; Bustamante, Ramiro O.; Celesti-Grapow, Laura; Chytry, Milan; Colautti, Robert I.; Essl, Franz; Foxcroft, Llewellyn C.; Garcia-Berthou, Emili; Gollasch, Stephan; Hierro, Jose; Hufbauer, Ruth A.; Hulme, Philip E.; Jarosik, Vojtech; Jeschke, Jonathan M.; Karrer, Gerhard; Mack, Richard N.; Molofsky, Jane; Murray, Brad R.; Nentwig, Wolfgang; Osborne, Bruce; Pysek, Petr; Rabitsch, Wolfgang; Rejmanek, Marcel; Roques, Alain; Shaw, Richard; Sol, Daniel; Van Kleunen, Mark; Vila, Montserrat; Von der Lippe, Moritz; Wolfe, Lorne M.; Penev, LyubomirThe Editorial presents the focus, scope, policies, and the inaugural issue of NeoBiota, a new open access peer-reviewed journal of biological invasions. The new journal NeoBiota is a continuation of the former NEOBIOTA publication series. The journal will deal with all aspects of invasion biology and impose no restrictions on manuscript size neither on use of color. NeoBiota implies an XML-based editorial workflow and several cutting-edge innovations in publishing and dissemination, such as semantic markup of and enhancements to published texts, data publication, and extensive cross-linking within the journal and to external sources.
- ItemPlant diversity drives global patterns of insect invasions(Nature Research, 2018) Liebhold, Andrew M.; Yamanaka, Takehiko; Roques, Alain; Augustin, Sylvie; Chown, Steven L.; Brockerhoff, Eckehard G.; Pysek, PetrDuring the last two centuries, thousands of insect species have been transported (largely inadvertently) and established outside of their native ranges worldwide, some with catastrophic ecological and economic impacts. Global variation in numbers of invading species depends on geographic variation in propagule pressure and heterogeneity of environmental resistance to invasions. Elton’s diversity-invasibility hypothesis, proposed over sixty years ago, has been widely explored for plants but little is known on how biodiversity affects insect invasions. Here we use species inventories from 44 land areas, ranging from small oceanic islands to entire continents in various world regions, to show that numbers of established insect species are primarily driven by diversity of plants, with both native and non-native plant species richness being the strongest predictor of insect invasions. We find that at large spatial scales, plant diversity directly explains variation in non-native insect species richness among world regions, while geographic factors such as land area, climate and insularity largely affect insect invasions indirectly via their effects on local plant richness.
- ItemTroubling travellers : are ecologically harmful alien species associated with particular introduction pathways?(Pensoft Publishers, 2017) Pergl, Jan; Pysek, Petr; Bacher, Sven; Essl, Franz; Genovesi, Piero; Harrower, Colin A.; Hulme, Philip E.; Jeschke, Jonathan M.; Kenis, Marc; Kuhn, Ingolf; Perglova, Irena; Rabitsch, Wolfgang; Roques, Alain; Roy, David B.; Roy, Helen E.; Vila, Montserrat; Winter, Marten; Nentwig, WolfgangPrioritization 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 the European alien species database DAISIE (www.europe-aliens.org) supplemented by the EASIN catalogue (European Alien Species Information Network), and expert knowledge. Plants introduced by the pathways release, corridor and unaided were disproportionately more likely to have ecological impacts than those introduced as contaminants. In contrast, impacts were not associated with particular introduction pathways for invertebrates, mammals or fish. Thus, while for plants management strategies should be targeted towards the appropriate pathways, for animals, management should focus on reducing the total number of taxa introduced, targeting those pathways responsible for high numbers of introductions. However, regardless of taxonomic group, having multiple introduction pathways increases the likelihood of the species having an ecological impact. This may simply reflect that species introduced by multiple pathways have high propagule pressure and so have a high probability of establishment. Clearly, patterns of invasion are determined by many interacting factors and management strategies should reflect this complexity.
