“…However, trends may differ between terrestrial and aquatic environments. For instance, the warming of North American lakes is likely to increase thermal suitability for southern species of fishes that could expand their distribution poleward into non-native regions, potentially as far as the Arctic (Sharma et al 2007;Della Venezia et al 2018).…”

Four priority areas to advance invasion science in the face of rapid environmental change

Unprecedented rates of introduction and spread of non-native species pose burgeoning challenges to biodiversity, natural resource management, regional economies, and human health. Current biosecurity efforts are failing to keep pace with globalization, revealing critical gaps in our understanding and response to invasions. Here, we identify four priority areas to advance invasion science in the face of rapid global environmental change. First, invasion science should strive to develop a more comprehensive framework for predicting how the behavior, abundance, and interspecific interactions of non-native species vary in relation to conditions in receiving environments and how these factors govern the ecological impacts of invasion. A second priority is to understand the potential synergistic effects of multiple co-occurring stressors – particularly involving climate change – on the establishment and impact of non-native species. Climate adaptation and mitigation strategies will need to consider the possible consequences of promoting non-native species, and appropriate management responses to non-native species will need to be developed. The third priority is to address the taxonomic impediment. The ability to detect and evaluate invasion risks is compromised by a growing deficit in taxonomic expertise, which cannot be adequately compensated by new molecular technologies alone. Management of biosecurity risks will become increasingly challenging unless academia, industry, and governments train and employ new personnel in taxonomy and systematics. Fourth, we recommend that internationally cooperative biosecurity strategies consider the bridgehead effects of global dispersal networks, in which organisms tend to invade new regions from locations where they have already established. Cooperation among countries to eradicate or control species established in bridgehead regions should yield greater benefit than independent attempts by individual countries to exclude these species from arriving and establishing.

“…Given their high economic impacts, managing unintentional introduction pathways (i.e. 'Stowaway' and 'Contaminants) should be a priority for future biosecurity efforts, which must adapt to growing trends in global shipping (Sardain et al 2019), and increased survivability of stowaways due to climate change (Pyke et al 2008;Della Venezia et al 2018;Kourantidou et al 2015;Kaiser and Kourantidou 2021).…”

Introduction pathways play a pivotal role in the success of Invasive Alien Species (IAS) – the subset of alien species that have a negative environmental and/or socio-economic impact. Pathways refer to the fundamental mechanism that leads to the introduction of a species outside of its native range – marking the beginning of all alien species invasions. Increased knowledge of pathways is essential to help reduce the flow and impacts of IAS and ultimately improve their management. Here we use the InvaCost database, a comprehensive repository on the global monetary impacts of invasive alien species, combined with the CBD hierarchical classification of introduction pathways to address four key questions: (i) Are particular IAS introduction pathways economically impactful? (ii) How are costs taxonomically and spatially distributed across pathways? (iii) Are there differences in costs between species introduced intentionally and unintentionally? and (iv) is there a relationship between the number of possible introduction pathways of IAS and their costs? We found first that both the total and average cost of species introduced through ‘Stowaways’ (US$144.9bn; US$89.4m) and ‘Contaminants’ pathways (US$99.3bn; US$158.0m) were more costly than species introduced primarily through ‘Escape’ (US$87.4bn; US$25.4m) and ‘Release’ (US$64.2bn; US$16.4m). Second, insects drove the costs of unintentional introductions whilst mammals drove the costs of intentional introductions; ‘Stowaways’ had the highest costs in Asia, Central America, North America and Diverse/Unspecified regions, whilst Antarctic-Subantarctic and Oceania incurred the greatest costs from species introduced through ‘Release’. Third, the cost of species introduced unintentionally is more than double the cost of species introduced intentionally ($192bn vs. $90bn). Equally, species introduced unintentionally cost more on average than species introduced intentionally in terms of damage, management, and mixed costs. Finally, the total and average cost of IAS was not related to their number of introduction pathways. Our findings provide important material for the targeting of priority pathways - something that will be critical in prioritising limited management budgets to combat the current acceleration of species invasions.

AlienScenarios, a three-year project starting in March 2019, will evaluate for the first time the range of plausible futures of biological invasions for the 21st century. AlienScenarios consists of seven project partners and seven integrated complementary subprojects. We will develop the qualitative narratives for plausible futures of global alien species richness and impacts in the 21st century – the Alien Species Narratives (ASNs). The ASNs further serve as overarching concept to parameterize quantitative models of global, continental and regional futures of biological invasions. We will also establish the first global mechanistic invasion model considering major processes of biological invasions such as source pools, driver dynamics and establishment rates. Further, we will assess the impacts of invasive alien species (IAS) in terms of economic costs according to the different ASNs. In addition, we will assess the consequences of different levels of implementation of the European Union Regulation on IAS. Providing some more detailed regional information, we will analyse changes of the functional composition of communities in mountain regions under different scenario storylines and will extend the analyses to the Global South using Panama as a country-level case study. Finally, the results of the other WPs will be synthesized, and the approach and results of AlienScenarios will be discussed with and communicated to stakeholders and the wider community. AlienScenarios will provide crucially needed insights for pro-active alien species management and policy. It will thus make an important contribution to global assessments and projections of biodiversity and ecosystem services, as well as regional policies (e.g. EU regulation on IAS).
