Global economic costs of aquatic invasive alien species

The Science of The Total Environment, Journal Year: 2021, Volume and Issue: 775, P. 145238 - 145238

Published: Jan. 20, 2021

Much research effort has been invested in understanding ecological impacts of invasive alien species (IAS) across ecosystems and taxonomic groups, but empirical studies about economic effects lack synthesis. Using a comprehensive global database, we determine patterns trends costs aquatic IAS by examining: (i) the distribution these taxa, geographic regions cost types; (ii) temporal dynamics costs; (iii) knowledge gaps, especially compared to terrestrial IAS. Based on recorded from existing literature, conservatively summed US$345 billion, with majority attributed invertebrates (62%), followed vertebrates (28%), then plants (6%). The largest were reported North America (48%) Asia (13%), principally result resource damages (74%); only 6% management. magnitude number highest United States for semi-aquatic taxa. Many countries known had no costs, Africa Asia. Accordingly, network analysis revealed limited connectivity among countries, indicating disparate reporting. Aquatic have increased recent decades several orders magnitude, reaching at least US$23 billion 2020. Costs are likely considerably underrepresented IAS; 5% species, despite 26% invaders being aquatic. Additionally, 1% invasion marine species. thus substantial, underreported. over time expected continue rising future invasions. We urge improved reporting managers, practitioners researchers reduce gaps. Few proactive investments; management spending is urgently needed prevent limit current damages.

Here, we identify four priority areas advance invasion science the face rapid global environmental change. First, should strive develop a more comprehensive framework for predicting how behavior, abundance, interspecific interactions vary relation conditions receiving environments these factors govern ecological impacts invasion. A second is understand potential synergistic effects multiple co-occurring stressors— particularly involving climate change—on establishment impact species. Climate adaptation mitigation strategies will need consider possible consequences promoting species, appropriate management responses be developed. The third address taxonomic impediment. ability detect evaluate risks compromised by growing deficit expertise, which cannot adequately compensated new molecular technologies alone.

In invasion – a dynamic rapidly evolving discipline the proliferation technical has lacked standardised framework its development.

Inconsistencies stem from exponential increase scientific publications on patterns processes biological invasions authored by experts disciplines countries since 1990s, as well legislators policymakers focusing practical applications, regulations, management resources. Aligning standardising stakeholders remains challenge science. Here, we review evaluate multiple terms used (e.g. ‘non‐native’, ‘alien’, ‘invasive’ or ‘invader’, ‘exotic’, ‘non‐indigenous’, ‘naturalised’, ‘pest’) propose simplified terminology. streamlined translate into 28 other languages based ( i ) denoting species transported beyond their natural biogeographic range, ii ‘established non‐native’, i.e. those non‐native that have established self‐sustaining populations new location(s) wild, iii ‘invasive non‐native’ recently spread are spreading invaded range actively passively without human mediation.

Are the “100 of the world’s worst” invasive species also the costliest?

Biological Invasions, Journal Year: 2021, Volume and Issue: 24(7), P. 1895 - 1904

Abstract Biological invasions are increasing worldwide, damaging ecosystems and socioeconomic sectors. Two decades ago, the “100 of world’s worst” invasive alien species list was established by IUCN to improve communications , identifying particularly ‘flagship’ invaders globally (hereafter, worst ). Whilst this has bolstered invader awareness, whether especially economically how they compare other ) remain unknown.

The Functional Response Ratio (FRR): advancing comparative metrics for predicting the ecological impacts of invasive alien species

Biological Invasions, Journal Year: 2019, Volume and Issue: 21(8), P. 2543 - 2547

Published: May 11, 2019

The Functional Response (FR) has been identified as a powerful predictive tool to forecast the ecological impacts of existing, emerging and future invasive alien species. In particular, parameters attack rate handling time h may be invaders when utilised in comparison with trophically analogous natives. However, researchers many cases face somewhat contradictory impact predictions based on use one parameter or other. Here, we thus propose new metric, Ratio (FRR), which is simply divided by h: that is, FRR = a/h. Given high values low should associate impact, vice versa, metric balances information from both parameters. This also resolves contradictions gives opposite Using multiple examples obtained literature, find indeed such are consistently higher than those natives, irrespective experimental environmental context. Accordingly, provides novel reliable for scientists, stakeholders practitioners predict species across taxa trophic groups.

Despite voluminous literature identifying the impacts of invasive species, summaries monetary costs for some taxonomic groups remain limited. Invasive alien crustaceans often have profound on recipient ecosystems, but there may be great unknowns related to their economic costs. Using InvaCost database, we quantify and analyse reported associated with globally across taxonomic, spatial, temporal descriptors. Specifically, prominent aquatic - crayfish, crabs, amphipods, lobsters. Between 2000 2020, crayfish caused US$ 120.5 million in costs; vast majority (99%) being attributed representatives Astacidae Cambaridae. Crayfish-related were unevenly distributed countries, a strong bias towards European economies (US$ 116.4 million; mainly due signal Sweden), followed by from North America Asia.

Invasive alien species (IAS) negatively impact the environment and undermine human well-being, often resulting in considerable economic costs. The Mediterranean basin is a culturally, socially economically diverse region, harbouring many IAS that threaten societal integrity multiple ways. This paper first attempt to collectively quantify reported costs of basin, across range taxonomic, temporal spatial descriptors. We identify correlates from invasion damages management expenditures among key socioeconomic variables, determine network structures link countries invasive taxonomic groups. total amounted $27.3 billion, or $3.6 billion when only realised were considered, found have occurred over last three decades. Our understanding invasions was largely limited few, primarily western European terrestrial ecosystems, despite known presence numerous high-impact aquatic taxa. vast majority attributed losses ($25.2 billion) mostly driven by France, Spain lesser extent Italy Libya, with significantly fewer expenditure ($1.7 billion). Overall, increased through time, average annual between 1990 2017 estimated at $975.5 million. lack information large proportion countries, reflected connectivity analysis relationship highlights limits available data research effort needed improve collective different facets biological invasions. associated sheds light on knowledge gaps provides baseline for Mediterranean-centric approach towards building policies designing coordinated responses.

Contemporary perspectives on the ecological impacts of invasive freshwater fishes

Journal of Fish Biology, Journal Year: 2022, Volume and Issue: 103(4), P. 752 - 764

Published: Oct. 8, 2022

Introductions of non-native freshwater fish continue to increase globally, although only a small proportion these introductions will result in an invasion. These invasive populations can cause ecological impacts the receiving ecosystem through processes including increased competition and predation pressure, genetic introgression transmission pathogens. Definitions impact emphasize that shifts strength are insufficient for characterizing alone and, instead, must be associated with quantifiable decline biological and/or diversity lead measurable loss or change functioning. Assessments should thus consider multiple effects potentially occur from where, example, common carp Cyprinus carpio combination bottom-up top-down that, entirety, lake stable states decreased species richness abundances biotic communities. Such far-reaching also align contemporary definitions collapse, given they involve substantial persistent declines biodiversity functions cannot recovered unaided. Thus, while not all introduced fishes become invasive, those do develop impacts, where some on functioning might sufficiently harmful considered as contributing collapse.
