“…On the contrary, Henry and Sorte (2021) found that marine species that caused high negative impacts in their native ranges were also more detrimental as neonatives when compared to species with low impacts in their native range, although in six species (of the seven studied), negative impacts in neonative ranges were noticeably larger than those in native ranges.…”

“…Sorte et al (2010) detected similar impact levels between neonative and alien populations, although the authors noted that their results were limited by scarce data for neonatives. On the contrary, Henry and Sorte (2021) found that marine species that caused high negative impacts in their native ranges were also more detrimental as neonatives when compared to species with low impacts in their native range, although in six species (of the seven studied), negative impacts in neonative ranges were noticeably larger than those in native ranges.…”

“…Conservation and management decisions are often based on the dichotomy native versus alien , which assumes that the former needs to be protected and the latter needs to be managed when harming biodiversity (Shah, 2020). In the case of neonatives, however, this distinction might not be clear because species that colonize new regions on their own, for example, under climate change, may also threaten local native biodiversity (Henry & Sorte, 2021; Pecl et al, 2017; Wallingford et al, 2020) and/or reduce uniqueness of an ecosystem’s flora and fauna (Rew et al, 2020; Wardle et al, 2011). In the light of contemporary climate change, a growing number of species is predicted to expand their ranges, e.g.…”

“…To define and measure impacts reported in the literature, we employed the International Union for Conservation of Nature (IUCN) Environmental Impact Classification for Alien Taxa (EICAT) framework, which has been developed to assess negative impacts caused by alien taxa to native biodiversity at different levels of organization (Blackburn et al, 2014; IUCN, 2020a, 2020b). EICAT has been used to compare the impacts of alien species across regions and taxonomic groups (Evans et al, 2016; Kumschick et al, 2017; Volery et al, 2021), and its use has been recently extended to both native and neonative species (Canavan et al, 2019; Henry & Sorte, 2021).…”

Aim: Anthropogenic environmental modifications such as climate or land-use change are causing species to move on their own beyond their native ranges. As this phenomenon will increase in the near future, it is crucial to determine whether rangeexpanding species, or neonatives, are more or less likely than native and alien species to impact their recipient ecosystems. Here, we compared impact magnitudes of bark beetle species from their native, neonative and alien ranges, simultaneously. Location: Global. Methods:We formulated four general scenarios about the magnitude of environmental impacts in different ranges (native, neonative and alien) based on hypotheses commonly used in invasion biology. We tested these scenarios globally on Dendroctonus bark beetles, asking whether they have the most harmful impacts in their native, neonative or alien ranges. Impacts reported in the literature were assessed with the IUCN Environmental Impact Classification for Alien Taxa (EICAT). Results:We found that bark beetles cause the most harmful impacts in their native ranges, followed by the neonative ranges, while impacts in their alien ranges are the lowest. This indicates that the more dissimilar the environment is from that in the native range, the lower the probability of high-impact magnitudes. Our results align with several non-exclusive hypotheses, e.g. pre-adaptation and habitat filtering, while they do not support others, e.g. enemy release or Darwin's naturalization. The results are also in contrast with previous studies on vertebrates and plants, which found no or mixed differences in impact magnitudes with biogeographic origin.Main conclusions: Our analysis suggests that bark beetles, like other species that are keystone and abundant in their native ranges, have generally lower impacts when introduced to novel environments due to biotic resistance or lack of pre-adaptation.Research and management implications regarding the impacts of neonative and alien populations are also discussed.

“…Specifically, the strength of novel predatory interactions may vary from negligible to relevant, ultimately altering the structure and dynamics of food webs and affecting ecosystem processes (Bartley et al, 2019;Wallingford et al, 2020;Henry & Sorte, 2022) analogously to what is observed for non-indigenous invasive species ("native invaders", sensu Simberloff, 2011;Carey et al, 2012). For ichthyofauna, in particular, a number of thermophilic pelagic species have increased their distribution range and relative abundance in the Mediterranean (Givan et al, 2018;Azzurro et al, 2019).…”

Variation in the stable isotope trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766) from two Mediterranean sites: insights from a global meta-analysis

A direct consequence of sea warming is the shift in the distribution range of thermo-tolerant species that have the potential to determine novel inter-specific interactions, ultimately altering food web structures and ecosystem processes. In this study, we investigated the trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766), a pelagic predator that has recently expanded its distribution in the Mediterranean basin and for which scant information is available on its functional role in recently-colonised areas. Nitrogen and carbon stable isotopes were determined in muscle tissues of bluefish specimens collected in south-east Italy in the Gulf of Taranto (NW Ionian Sea) and in the Strait of Otranto (SW Adriatic Sea) at two coastal sites showing contrasting oceanographic conditions. The bluefish trophic position (TP) was estimated using locally abundant forage fish species as isotopic baselines. The results indicated for bluefish from the Strait of Otranto a TP value of 5.1, significantly higher than that determined in the Gulf of Taranto (4.2), and exceeding stomach content-based estimations reported by the online database FishBase and by literature sources. A synthesis of 30 publications reporting isotopic data for the bluefish and its potential prey at a global scale indicated that the species’ trophic position varied considerably between 2.7 and 5.2. The observed variability depended on locationand on the baseline species used in the estimations. Yet, a significant difference in trophic position was observed for bluefish from transitional and inshore environments as compared with offshore areas, mirroring the results obtained from the Gulf of Taranto and the Strait of Otranto. The findings of the study highlight the high trophic plasticity characterizing the bluefish in recently colonized areas, suggesting that it may play a key role in facilitating the expansion of its distribution range. However, additional investigations are essential to provide an advanced resolution of the bluefish functional role in Mediterranean coastal food webs.

The assessment of marine bioinvasion diversity and history

A significant challenge in comparing and contrasting regional reviews of non-native marine species diversity is that evaluation methods vary widely, resulting in highly inconsistent taxonomic, habitat and historical coverage even in ostensibly well-studied regions. It is thus difficult to interpret whether strikingly different numbers of non-native species in different regions reflect differential invasion patterns or different assessment criteria and capabilities. We provide a comprehensive guide to the methods and techniques to assess the diversity and timing history of non-native and cryptogenic marine species. We emphasize the need to broaden taxonomic and habitat breadth when documenting invasions, to use a broader and deeper search term menu (including using older terms), to thoroughly access global systematic and invasion literature for local, regional records, and to delve deeper into invasion timing to avoid the use of dates-of-publication to assess invasion tempo and rates. Fundamental in all invasions work is the reassessment of the status of ostensibly native species which in fact may have been introduced decades or centuries earlier. We expand to 14 categories the criteria for the recognition of non-native species. Without thorough and vetted modern and historical assessments of the scale of invasions across temperate, subtropical, and tropical marine ecosystems, our ability to look deep into marine community ecology, evolution, and biogeography is strikingly compromised, as is our ability to frame robust invasion policy and management plans.
