1 INTRODUCTION The expansion and intensification of global trade and transport have resulted in increasing rates of intra- and intercontinental biotic exchange (Capinha et al., 2023; Hulme, 2021; IPBES, 2023; Seebens et al., 2017). While most established non-native species are currently inconspicuous additions to regional biotas, a sizable minority causes considerable ecological damages (Diagne et al., 2021; Kumschick et al., 2015; Vilà et al., 2011).

Um die Artenvielfalt in Österreichs Kulturlandschaft ist es nicht gut bestellt. Fast die Hälfte aller Brutvögel – exakt 48 Prozent – sind in nur 25 Jahren aus Feld und Flur verschwunden. Das zeigen Zahlen der Vogelschutzorganisation „BirdLife“. Der ebenso rasante Rückgang von Insekten ist mittlerweile zum Allgemeinwissen geworden. Und dies, obwohl Österreich mit dem Agrar-Umweltprogramm ÖPUL Vorreiter in der EU ist – und obwohl viele Bauern und Bäuerinnen mit der Natur wirtschaften.

3.8 Species invasiveness Analysing the random effects, we can identify the species with the highest invasiveness propensity (i.e., rate of spread across regions after accounting for the influences of covariates). After accounting for the other effects described above, the random invasiveness rate captures the tendency of different species to spread. Table  in Appendix  presents the top five alien species in each taxonomic group.

Overview of the global data on genome size for taxonomic groups Among angiosperms and gymnosperms with available monoploid genome size data (i.e. genome size of one unreplicated chromosome set), the percentages of invasive species were similar, but gymnosperms had a higher percentage of naturalized species than angiosperms (Table ; Fig. 1).
