This limits the synthesis of emergent patterns in invasion ecology and generalisations for conservation actions. In order to produce a broad and general assessment of the invasion pattern in aquatic habitats we here propose a macroecological approach to assess the drivers of occurrence of alien species within the whole biota microorganisms, plants and animals across several natural freshwater ecosystems of Italy. We simultaneously tested three groups of variables propagule pressure, abiotic and biotic characteristics , selected as putative predictors of invasibility of a site. Propagule pressure, expressed as proximity to larger inhabited areas, and differences in the native species richness of the receiving community, had a significant role in determining the number of alien species occurrences. Furthermore, body size influenced the occurrence and colonization processes of alien species. Finally, climatic characteristics were relevant in determining the chances that a site was invaded, confirming the role of these abiotic filters in the invasion process. 12 Published version http //www.scopus.com/record/display.url eid=2 s2.0 85030546255 origin=inward Alien species in italian freshwater ecosystems A macroecological assessment of invasion drivers 2017_Colangeloetal_IAS.pdf Articolo in rivista Regional Euro Asian Biological Invasions Centre, 1798 6540 Aquatic Invasions Print Aquatic Invasions Print Aquatic Invasions Print paolo.colangelo COLANGELO PAOLO fabio.cianferoni CIANFERONI FABIO angela.boggero BOGGERO ANGELA aldo.marchetto MARCHETTO ALDO diego.fontaneto FONTANETO DIEGO ilaria.rosati ROSATI ILARIA |
