As one of the central topics in ecology, efforts to determine the factors associated with alien species’ invasions have been rapidly increasing in the last decades. Yet, our ability to generalize and predict the outcome of particular species introductions remains limited. This is partly due to the prevailing focus on individual species traits, an approach that is less suitable to capture the inherent complexity of the naturalization-invasion process. Recently, Guo et al. (2018, 2019) demonstrated the usefulness of Grime’s seminal concept of adaptive strategies – competitors, stress-tolerators and ruderals (CSR) – for explaining plant naturalizations worldwide, using a global dataset of >3000 vascular plant species and accounting for phylogenetic relatedness, species’ native biomes, native range size and introduction history. They revealed that the C- and R-selection were positively, whilst S-selection negatively, associated with the likelihood of a species becoming naturalized outside its native range. However, due to the limited data availability, these authors did not test the applicability of the scheme for the invasion stage of the process. Here we tested the effects of the CSR adaptive strategies at different stages along the introduction–naturalization–invasion continuum, using the Pladias Database of Czech Flora and Vegetation. Our findings demonstrate the universal utility of the CSR scheme to explain the success of alien plant species in their introduced ranges.
