“…Importantly, these indicators are general enough to cross-predict between distantly related clades (i.e. models calibrated on one clade can provide useful predictions onto another) while remaining within an acceptable range of error [42]. Although these indicators are generic, the models can be re-calibrated for clades originating from other biogeographical regions to accommodate particular features of the focal taxa.…”

“…Black lists are based on the quantification of invasion risk of species to provide robust and quantifiable justification for the regulation of species that pose a high risk of becoming invasive. Although such lists are widely advocated as a practical approach for simplifying the process of regulating intentional introductions [45], objective protocols for populating such lists are still lacking, even for groups with many invasive species such as acacias and eucalypts (more subjective protocols based on expert knowledge have been developed [46] but have shown limited efficacy and reproducibility [42,47]). Our screening approach provides exactly such a probabilistic assessment of species invasiveness (table 1), and thus has the potential for being widely adopted.…”

Global predictors of alien plant establishment success: combining niche and trait proxies

et al. 2019

Biological invasions are on the rise globally. To reduce future invasions, it is imperative to determine the naturalization potential of species. Until now, screening approaches have relied largely on species-specific functional feature data. Such information is, however, time-consuming and expensive to collect, thwarting the screening of large numbers of potential invaders. We propose to resolve such data limitations by developing indicators of establishment success of alien species that can be readily derived from open-access databases. These indicators describe key features of successfully established aliens, including estimates of potential range size, niche overlap with human-disturbed environments, and proxies of species traits related to their palaeoinvasions and local dominance capacities. We demonstrate the utility of this new approach by applying it to two large and highly invasive plant groups: Australian acacias and eucalypts. Our results show that these indicators robustly predict establishment successes and failures in each clade independently, and that they can cross-predict establishment in these two clades. Interestingly, the indicator identified as most important was species potential range size on Earth, a variable too rarely considered as a predictor. By successfully identifying key features that predispose Australian plants to naturalize, we provide an objective and cost-effective protocol for flagging high-risk introductions.

“…There is an urgent need to increase our understanding of the impacts of non-native plant invasions on the relatively high and unique biodiversity of (sub-)tropical islands, as these systems are particularly susceptible to plant invasions (Kueffer et al 2010;Essl et al 2019). In these systems, invasive vines form a particular risk given their potential to modify environmental conditions and exert strong effects on recipient plant communities (Gordon 1998;Harris et al 2007;Bray et al 2017;Gordon et al 2017). Although A. leptopus is a prominent example of a vine that has successfully invaded (sub-)tropical islands around the globe, its impacts on recipient plant communities have not yet been systematically quantified.…”

“…humidity, Gordon 1998;Horvitz et al 1998). These processes may drive disproportionate ecosystem impacts as compared to invasive plant species of other growth forms that do not actively modify the environmental conditions for the recipient plant community (Crooks 2002;Cuddington and Hastings 2004;Harris et al 2007;Kaproth et al 2013;Gordon et al 2017).…”

Antigonon leptopus invasion is associated with plant community disassembly in a Caribbean island ecosystem

et al. 2021

Invasions by non-native plant species are widely recognized as a major driver of biodiversity loss. Globally, (sub-)tropical islands form important components of biodiversity hotspots, while being particularly susceptible to invasions by plants in general and vines in particular. We studied the impact of the invasive vine A. leptopus on the diversity and structure of recipient plant communities on the northern Caribbean island St. Eustatius. We used a paired-plot design to study differences in species richness, evenness and community structure under A. leptopus-invaded and uninvaded conditions. Community structure was studied through species co-occurrence patterns. We found that in plots invaded by A. leptopus, species richness was 40–50% lower, and these plots also exhibited lower evenness. The magnitude of these negative impacts increased with increasing cover of A. leptopus. Invaded plots also showed higher degrees of homogeneity in species composition. Species co-occurrence patterns indicated that plant communities in uninvaded plots were characterized by segregation, whereas recipient plant communities in invaded plots exhibited random co-occurrence patterns. These observations suggest that invasion of A. leptopus is not only associated with reduced species richness and evenness of recipient communities in invaded sites, but also with a community disassembly process that may reduce diversity between sites. Given that A. leptopus is a successful invader of (sub-)tropical islands around the globe, these impacts on plant community structure highlight that this invasive species could be a particular conservation concern for these systems.

“…The vine plant Epipremnum aureum (Linden and André) G. S. Bunting is a representative invasive species that presents a threat to original ecosystems. This species is an evergreen vine plant native to the Solomon Islands (Ohkawa and Hayashi 2016) that has invaded many areas of the world, including Central and South America, Brazil, South Africa, India, Southwest Asia, China, Hawaii, Florida, and Japan (Yan Chong et al 2011;Gordon et al 2017;Moodley et al 2017; US Forest Service 2021). E. aureum is easily propagated and requires little maintenance (Boyce 2004).…”

Understanding the regrowth condition and pattern for the vine plant Epipremnum aureum is important for effective removal of this invasive species. The purpose of this study was to clarify the influence of the light environment, size of the plant body, and existence of roots on the survival and regrowth of a piece of the plant body of E. aureum. We surveyed the survival and regrowth of E. aureum for plant cuttings of different sizes under three light conditions representing the outside, edge, and inside of forests (Experiment 1), and for plant cuttings of different sizes with or without roots inside forests (Experiment 2). In Experiment 1, we observed a high mortality outside forests, but confirmed higher survival rate and probability of regrowth at forest edges and inside forests. Even one leaf with a stem and root could regrow under low light intensity, whereas the amount of regrown plant organs or tissue was higher for a larger cutting. In Experiment 2, the number of roots increased more rapidly for plant cuttings without initial roots than for those with initial roots, although the amount of regrown plant tissue increased with increasing cutting size. Even small pieces of the plant body of E. aureum with no roots frequently survived and regrew under low light intensity. This indicates that small pieces of the plant body should not be left at forest edges or inside forests during removal work.
