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).

The United States has thousands of invasive species, representing a sizable, but unknown burden to the national economy. Given potential economic repercussions quantifying these costs is paramount importance both for economies and invasion management. Here, we used novel global database (InvaCost) quantify overall species in across spatiotemporal, taxonomic, socioeconomic scales. From 1960 2020, reported totaled $4.52 trillion (USD 2017). Considering only observed, highly reliable costs, this total cost reached $1.22 with an average annual $19.94 billion/year. These increased from $2.00 billion annually between 1969 $21.08 2010 2020. Most (73%) were related resource damages losses ($896.22 billion), as opposed management expenditures ($46.54 billion).

Economic costs of biological invasions within North America

Invasive species can have severe impacts on ecosystems, economies, and human health. Though the economic of invasions provide important foundations for management policy, up-to-date syntheses these are lacking. To produce most comprehensive estimate invasive costs within North America (including Greater Antilles) to date, we synthesized impact data from recently published InvaCost database. Here, report that cost American economy at least US$ 1.26 trillion between 1960 2017. Economic climbed over recent decades, averaging 2 billion per year in early 1960s 26 2010s. Of countries America, United States (US) had highest recorded costs, even after controlling research effort each country ($5.81 source US). taxa habitats could be classified our database, vertebrates were associated with greatest terrestrial incurring monetary impacts. In particular, cumulatively (from 1960–2017) agriculture forestry sectors 527.07 34.93 billion, respectively. Reporting issues (e.g., quality or taxonomic granularity) prevented us synthesizing all available studies. Furthermore, very few known reported costs. Therefore, while massive, is likely conservative. Accordingly, expanded more rigorous reports necessary invasion estimates, then support data-based decisions actions towards invasions.

In this study, we collected reviewed reported data the invasive using InvaCost, most global database invasion costs. We analysed how total (i.e. observed potential/predicted) empirically incurred only) fish invasions are distributed geographically temporally assessed which socioeconomic sectors affected. Fish potentially caused loss at least US$37.08 billion (US2017 value) globally, from just 27 species.

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).

Pioneering investigations on the effects of introduced populations community structure, ecosystem functioning and services have focused invaders taxonomic diversity. However, taxonomic-based diversity metrics overlook heterogeneity species roles within among communities. As homogenizing biological invasions processes can be subtle, they may require use functional indices to properly evidenced. Starting from listing major indices, alongside presentation their strengths limitations, we focus studies pertaining invasive native communities recipient ecosystems using indices. By doing so, reveal that strongly vary at onset invasion process, while it stabilizes intermediate high levels invasion. changes occurring during lag phase an been poorly investigated, show is still unknown whether there are consistent in could indicate end phase. Thus, recommend providing information stage under consideration when computing metrics. For existing literature, also surprising very few explored difference between organisms same trophic levels, or assessed non-native organism establishment into a non-analogue versus analogue community. valuable tools for obtaining in-depth diagnostics structure functioning, applied timely implementation restoration plans improved conservation strategies.

Abstract The reported costs of invasive alien species from the global database InvaCost are heterogenous and cover different spatio-temporal scales. A standard procedure for aggregating cost estimates is necessary to ensure repeatability comparativeness studies. We introduce here invacost R package, an open-source software designed query analyse database. illustrate this package its framework with data associated invertebrates. First, provides updates dynamic directly in analytical environment R. Second, it helps understand heteregoneous nature monetary species, processes harmonize data, inherent biases such data. Third, readily complementary methods investigate at scales, all while accounting econometric statistical issues. This tool will be useful scientists working on by (i) facilitating access use multi-disciplinary resource (ii) providing a which facilitate reproducibility comparability among studies, one major critics topic until now. It should further interdisciplinary works including economists invasion ecology researchers.

The ever-increasing number of introduced species profoundly threatens global biodiversity. While the ecological and evolutionary consequences invasive alien are receiving increasing attention, their economic impacts have largely remained understudied, especially in France. Here, we aimed at providing a general overview monetary losses (damages caused by) expenditures (management of) associated with This country has long history presence, partly due to its long-standing trade activities, highly developed tourism, presence overseas territories different regions globe, resulting conservative minimum 2,750 species. By synthesizing for first time incurred by Metropolitan France French territories, obtained 1,583 cost records 98 We found that they total amount ranging between US$ 1,280 million 11,535 costs over period 1993–2018. extrapolated invading France, which were reported other countries but not yielded an additional from 151 3,030 millions. Damage nearly eight times higher than management expenditure. Insects, particular Asian tiger mosquito Aedes albopictus yellow fever Ae. aegypti , totalled very high costs, followed non-graminoid terrestrial flowering aquatic plants ( Ambrosia artemisiifolia Ludwigia sp.
