The global increase in biological invasions is placing growing pressure on the management of ecological and economic systems. However, effectiveness current expenditure difficult to assess due a lack standardised measurement across spatial, taxonomic temporal scales. Furthermore, there no quantification spending difference between pre-invasion (e.g. prevention) post-invasion control) stages, although preventative measures are considered be most cost-effective. Here, we use comprehensive database invasive alien species costs (InvaCost) synthesise model invasions, order provide better understanding stage at which these expenditures occur. Since 1960, reported have totalled least US$95.3 billion (in 2017 values), considering only highly reliable actually observed - 12-times less than damage from ($1130.6 billion). Pre-invasion ($2.8 billion) was over 25-times lower ($72.7 Management were heavily geographically skewed towards North America (54%) Oceania (30%). largest shares directed invertebrates terrestrial environments.

Economic costs of invasive alien ants worldwide

Biological Invasions, Journal Year: 2022, Volume and Issue: 24(7), P. 2041 - 2060

Published: April 25, 2022

Abstract Invasive ants are amongst the most destructive and widespread invaders across globe; they can strongly alter invaded ecosystems responsible for loss of native ant species. Several studies have reported that invasive also lead to substantial economic costs. In this study, we search, describe analyse 1342 costs compiled in InvaCost database. Economic costs, since 1930 12 species 27 countries, totalled US$ 51.93 billion, from which 10.95 billion were incurred, 40.98 potential (i.e., expected or predicted costs). More than 80% total associated with only two species, Solenopsis invicta Wasmannia auropunctata ; USA Australia. Overall, damage amounted 92% cost, mainly impacting agriculture, public social welfare sectors. Management primarily post-invasion management (US$ 1.79 billion), much lower amounts dedicated prevention 235.63 million). Besides taxonomic bias, cost information was lacking an average 78% countries. Moreover, even countries where reported, such available 56% locations. Our synthesis suggests global massive but largely biased towards developed economies, a huge proportion underreported thus likely grossly underestimated. We advocate more improved reporting through better collaborations between managers, practitioners researchers, crucial basis adequately informing future budgets improving proactive actions ants.

Invasive Aedes aegypti and albopictus mosquitoes transmit viruses such as dengue, chikungunya Zika, posing a huge public health burden well having less understood economic impact. We present comprehensive, global-scale synthesis of studies reporting these costs, spanning 166 countries territories over 45 years. The minimum cumulative reported cost estimate expressed in 2022 US$ was 94.7 billion, although this figure reflects considerable underreporting underestimation. analysis suggests 14-fold increase with an average annual expenditure 3.1 maximum 20.3 billion 2013. Damage losses were order magnitude higher than investment management, only modest portion allocated to prevention.

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.

The European Union has historically been a hub for cultural development global trade, thus, extensive opportunities introduction spread alien species. While reported costs biological to some member states have recently assessed, ongoing knowledge gaps in taxonomic spatio-temporal data suggest that these were considerably underestimated.

Economic costs of invasive rodents worldwide: the tip of the iceberg

PeerJ, Journal Year: 2023, Volume and Issue: 11, P. e14935 - e14935

Published: March 24, 2023

Background Rodents are among the most notorious invasive alien species worldwide. These invaders have substantially impacted native ecosystems, food production and storage, local infrastructures, human health well-being. However, lack of standardized understandable estimation their impacts is a serious barrier to raising societal awareness, hampers effective management interventions at relevant scales. Methods Here, we assessed economic costs rodents globally in order help overcome these obstacles. For this purpose, combined analysed cost data from InvaCost database—the up-to-date comprehensive synthesis reported invasion costs—and specific complementary searches within beyond published literature. Results Our conservative analysis showed that rodent invasions reached total US$ 3.6 billion between 1930 2022 (annually 87.5 million 1980 2022), were significantly increasing through time. The highest was for muskrat Ondatra zibethicus (US$ 377.5 million), then unspecified Rattus spp. 327.8 followed by norvegicus specifically 156.6 million) Castor canadensis 150.4 million). Of costs, 87% damage-related, principally impacting agriculture predominantly Asia (60%), Europe (19%) North America (9%). study evidenced obvious underreporting with only 99 documents gathered globally, clear taxonomic gaps, reliability issues assessment, skewed breakdowns regions, sectors contexts. As consequence, represent very small fraction expected true ( e.g. , using less analytic approach would led global amount more than 80-times higher estimated here). Conclusions findings strongly suggest available information represents substantial underestimation incurred. We offer recommendations improving estimates fill knowledge gaps including: systematic distinction rodents’ impacts; monetizing indirect on health; greater integrative concerted research effort scientists stakeholders. Finally, discuss why how will stimulate provide support proactive sustainable strategies context invasions, which biosecurity measures should be amplified globally.

Alien species are a significant threat to natural ecosystems and human economies. Despite global efforts address this challenge, the documented number of alien is rapidly increasing worldwide. However, magnitude impact may vary significantly across habitats. For example, some habitats naturally less prone biological invasions due stringent abiotic biotic characteristics, selecting for limited introduced possessing traits closely related native organisms. Subterranean quintessential examples with strong environmental filters (e.g. lack light scarcity food), driving convergent adaptations in that have successfully adapted life darkness. these constraints, records subterranean has increased recent decades, but relevant literature remains largely fragmented mostly anecdotal. Therefore, even though caves generally considered very fragile ecosystems, their susceptibility impacts by untested other than specific cases. We provide first systematic survey synthesise available knowledge on globally.

Conceptual and ethical considerations in invasion science

BioScience, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 21, 2025

Abstract Invasion science addresses interconnected ecological, economic, and social challenges posed by the introduction of nonnative species. Therefore, invasion scientists have to consider reconcile interdisciplinary needs while addressing potential implications their findings. Navigating diverse disciplines, including environmental sciences, ecology, economics, humanities, seek arrive at informed decisions on risk, impact, management. Individual biases, uncertainties, systemic pressures influence ability maintain objectivity resist that might otherwise distort findings or applications. In present commentary, we examine conceptual ethical dilemmas within field science, particularly reputational risks discipline perpetuating its own relevance framing invasions as insurmountable challenges. discussion, highlight how incentive structures, biased assessments framing, conflicts interest may compromise discipline's integrity.
