“…In addition, we also detected a positive effect of road network density in explaining the range expansion of WITV. This result is reasonable, as the spread of alien vertebrates is often related to human transportation for food and pet (Du et al., 2024; García‐Díaz et al., 2018; Pili et al., 2023). We found that airport density exhibited a positive but relatively weak effect in explaining the range expansion, indicating that road may be more important than air transport for alien species spread at the jurisdiction scale for WITV as the road transportation can be often more prevalent than domestic airlines (Sprung et al., 2018).…”

“…However, information on human‐assisted dispersal is generally lacking especially for those unintentional introductions. Therefore, some proxy variables, such as the density of roads, airlines, and other traffic networks, are usually used to reflect the probability of human‐mediated introductions (Pili et al., 2023).…”

Understanding the determinants of the range expansion of invasive alien species is crucial for developing effective prevention and control strategies. Nevertheless, we still lack a global picture of the potential factors influencing the invaded range expansion across taxonomic groups, especially for the world's worst invaders with high ecological and economic impacts. Here, by extensively collecting data on 363 distributional ranges of 19 of world's worst invasive terrestrial vertebrates across 135 invaded administrative jurisdictions, we observed remarkable variations in the range expansion across species and taxonomic groups. After controlling for taxonomic and geographic pseudoreplicates, model averaging analyses based on generalized additive mixed‐effect models showed that species in invaded regions having climates more similar to those of their native ranges tended to undergo a larger range expansion. In addition, as proxies of propagule pressure and human‐assisted transportation, the number of introduction events and the road network density were also important predictors facilitating the range expansion. Further variance partitioning analyses validated the predominant role of climate match in explaining the range expansion. Our study demonstrated that regions with similar climates to their native ranges could still be prioritized to prevent the spread of invasive species under the sustained global change.

“…The increase in global trade has allowed several species to be present outside their native ranges, leading to the presence of more than 37,000 alien species globally (IPBES 2023) and to an exponential increase of invasive taxa (Meurisse et al 2019, Mormul et al 2022. The establishment of an alien species starts with overcoming the dispersal barrier, which is aided by humans through accidental transportation or species traded for commercial reasons (Seebens et al 2015, Meurisse et al 2019, Sinclair et al 2020, Mormul et al 2022, IPBES 2023, Pili et al 2023. For example, several animals are imported through the pet market, which is known to have a strong influence on their invasiveness (Lockwood et al 2019, Maceda-Veiga et al 2019, Gippet and Bertelsmeier 2021.…”

Analysis of potential niche shifts in alien pairs of mantis species (Insecta, Mantodea) with comments on the current taxonomic and ecological knowledge

Due to the pet and goods trade, several animals are now present in regions outside of their traditional native ranges. A peculiar situation has arisen in mantises, insects that are becoming more popular as pets: two genera (Hierodula and Tenodera) have begun to spread around the world, with two Hierodula species overlapping in Europe and two Tenodera species doing the same in North America. Such an event can lead to possible competition with both local taxa and alien congeneric sister species; the latter may reduce the impact of one of the invaders. Additionally, the situation allows the comparisons of niche shifts in displaced mantises, allowing us to understand whether such animals respect general patterns shown in terrestrial ectothermic invasive species. To do this, I adapted scripts from previous publications for analyzing niche overlap (Schoener’s D), niche expansion (E), and unfilling (U) through the centroid shift, overlap, unfilling, and expansion (COUE) scheme using presence records from GBIF and iNaturalist Research-Grade observations and bioclimatic variables available in BIOCLIM, selected according to variance inflation factor (VIF) values. I also evaluated the overlap between the sister species in the non-native range with D. Overall, there was relatively high niche expansion and unfilling patterns shared among the taxa, although species tended to have low abiotic overlap between native and alien ranges, and a relatively high niche overlap was present among congeneric species in the shared non-native area. However, such analyses may be biased due to chosen variables, taxonomic uncertainty, and lack of information on mantises’ ecology; particularly, the situation regarding H. tenuidentata/transcaucasica should be monitored and clarified, given the higher potential invasion risk of these species compared to other mantises and the uncertainties regarding which populations have reached Europe. Additionally, the biology of alien mantises should be studied in more detail in both native and non-native environments given the current critical lack of information.

“…The realisation of the damages and risks of alien species invasions to ecosystems and socio‐economy (Bacher et al., 2018; Diagne et al., 2021; Hawkins et al., 2015) have prompted countries worldwide to develop and enforce biosecurity policies and strategies (Kunming‐Montreal Global Biodiversity Framework—Convention on Biological Diversity, 2022; IPBES, 2023). Yet, decades after the initial calls for improved management of invasive alien species (Drake et al., 1989; Williamson et al., 1986), the global problem of biological invasions continues to escalate (Fenn‐Moltu, Ollier, Bates, et al., 2023a; Fenn‐Moltu, Ollier, Caton, et al., 2023b; Leroy et al., 2023; Pili et al., 2023; Richardson et al., 2023; Seebens et al., 2017), reflecting systemic failures in meeting biosecurity targets (IPBES, 2023; Latombe et al., 2023). Notably, a crucial biosecurity oversight is the integration of, and increasing access to, new source regions into the global flows of alien species (Hudgins et al., 2023), notwithstanding the shifting importance and the emergence of new transport and introduction pathways (Hulme, 2009; Hulme & Firn, 2015; Leroy et al., 2023; Seebens et al., 2018; Toomes et al., 2019).…”

The ever‐increasing and expanding globalisation of trade and transport underpins the escalating global problem of biological invasions. Developing biosecurity infrastructures is crucial to anticipate and prevent the transport and introduction of invasive alien species. Still, robust and defensible forecasts of potential invaders are rare, especially for species without known invasion history. Here, we aim to support decision‐making by developing a quantitative invasion risk assessment tool based on invasion syndromes (i.e., generalising typical attributes of invasive alien species). We implemented a workflow based on ‘Multiple Imputation with Chain Equation’ to estimate invasion syndromes from imputed datasets of species' life‐history and ecological traits and macroecological patterns. Importantly, our models disentangle the factors explaining (i) transport and introduction and (ii) establishment. We showcase our tool by modelling the invasion syndromes of 466 amphibians and reptile species with invasion history. Then, we project these models to amphibians and reptiles worldwide (16,236 species [c.76% global coverage]) to identify species with a risk of being unintentionally transported and introduced, and risk of establishing alien populations. Our invasion syndrome models showed high predictive accuracy with a good balance between specificity and generality. Unintentionally transported and introduced species tend to be common and thrive well in human‐disturbed habitats. In contrast, those with established alien populations tend to be large‐sized, are habitat generalists, thrive well in human‐disturbed habitats, and have large native geographic ranges. We forecast that 160 amphibians and reptiles without known invasion history could be unintentionally transported and introduced in the future. Among them, 57 species have a high risk of establishing alien populations. Our reliable, reproducible, transferable, statistically robust and scientifically defensible quantitative invasion risk assessment tool is a significant new addition to the suite of decision‐support tools needed for developing a future‐proof preventative biosecurity globally.
