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). Moreover, majority invaders terrestrial habitats ($643.51 billion, 53%) agriculture was most impacted sector ($509.55 taxonomic perspective, mammals ($234.71 billion) insects ($126.42 groups responsible greatest costs. apparent rising invasions, coupled increasing numbers current lack information known invaders, our findings provide critical policymakers managers.

Abstract The redclaw crayfish ( Cherax quadricarinatus ; hereafter redclaw), native to northern Australia and southern New Guinea, is among the largest freshwater decapods. It matures early considered highly prolific as females may lay over one thousand eggs in a single clutch. Despite generally preferring slow‐moving streams its range, it has wide environmental tolerance, making capable of establishing populations when introduced range other conditions habitats. These biological ecological features render suitable popular species for aquaculture worldwide, being second most important economically (after red swamp Procambarus clarkii ). Adding that, unique coloration fuels demand value aquarium enthusiasts, attractive pet trade. Today, widely translocated (67 countries/territories) various established wild (22 countries) have been reported on every continent except Antarctica. Information potential or observed impacts, however, sparse often anecdotal. To address this gap, comprehensive review compiles all available information species, covering taxonomy description, biology ecology, non‐native ranges accompanied with documented introduction pathways. Built upon these, we conducted socio‐economic classification distribution modelling. We reveal lack thorough impact assessments despite sufficient indications major observable impacts at local scales. call attention importance managing use prominent

Introduction pathways of economically costly invasive alien species

Biological Invasions, Год журнала: 2022, Номер 24(7), С. 2061 - 2079

Abstract Introduction pathways play a pivotal role in the success of Invasive Alien Species (IAS)—the subset alien species that have negative environmental and/or socio-economic impact. Pathways refer to fundamental processes leads introduction from one geographical location another—marking beginning all invasions. Increased knowledge is essential help reduce number introductions and impacts IAS ultimately improve their management . Here we use InvaCost database, comprehensive repository on global monetary IAS, combined with pathway data classified using Convention Biological Diversity (CBD) hierarchical classification compiled CABI Compendium, Global Database (GISD) published literature address five key points. Data were available for 478 individual IAS. For these, found both total annual average cost per introduced through ‘Stowaway’ (US$144.9bn; US$89.4m) ‘Contaminant’ (US$99.3bn; US$158.0m) higher than primarily ‘Escape’ (US$87.4bn; US$25.4m) ‘Release’ (US$64.2bn; US$16.4m). Second, recorded costs (both average) unintentionally was intentionally. Third, insects mammals, respectively, accounted greatest proportion intentionally at least records; had highest Asia, Central America, North America Diverse/Unspecified regions. Fourthly, given not related year first record introduction, but time gaps might blur true pattern. Finally, pathways. Although our findings are directly limited by data, they provide important material which can contribute priority measures, notably complementing studies associated ecologically harmful They also highlight crucial need fill remaining gaps—something will be critical prioritising budgets combat current acceleration

Citizen science is a vital partnership for invasive alien species management and research

iScience, Год журнала: 2023, Номер 27(1), С. 108623 - 108623

Опубликована: Дек. 3, 2023

Invasive alien species (IAS) adversely impact biodiversity, ecosystem functions, and socio-economics. Citizen science can be an effective tool for IAS surveillance, management, research, providing large datasets over wide spatial extents long time periods, with public participants generating knowledge that supports action. We demonstrate how citizen has contributed across the biological invasion process, especially early detection distribution mapping. However, we recommend could used more assessing impacts evaluating success of management. does have limitations, explore solutions to two key challenges: ensuring data accuracy dealing uneven coverage potential recorders (which limits dataset's "fit purpose"). Greater co-development stakeholders will help us better realize its process ecosystems globally while meeting needs participants, local communities, scientists, decision-makers.

Economic costs of invasive non-native species in urban areas: An underexplored financial drain

Urbanization is an important driver of global change associated with a set environmental modifications that affect the introduction and distribution invasive non-native species (species populations transported by humans beyond their natural biogeographic range established are spreading in introduced range; hereafter, species). These recognized as cause large ecological economic losses. Nevertheless, impacts these urban areas still poorly understood. Here we present synthesis reported costs using InvaCost database, demonstrate likely underestimated. Sixty-one have been to cumulative cost US$ 326.7 billion between 1965 2021 globally (average annual 5.7 billion).

Biological invasions are a major threat to global biodiversity with particularly strong implications for island biodiversity. Much research has been dedicated towards understanding historic and current changes in alien species distribution impacts on islands potential under future climate change. However, projections of how richness might develop the still lacking. In absence reliable projections, expert-based assessments valuable tool investigate importance different drivers pathways distributions biological invasions. These insights can guide subsequent quantification efforts inform invasive management policy. this study, we performed survey among 126 experts invasion science ranging from scientists managers decision makers focus systems until mid-21st century.

Of these, trade & transport was identified as most at introduction stage (99.2%) land use/cover change establishment (96.8%) spread (95.2%) stage.

Although the high costs of invasion are frequently cited and a key motivation for environmental management policy, synthesised data on scarce. Here, we quantify examine monetary biological invasions in United Kingdom (UK) using global synthesis reported costs. Invasive alien species have cost UK economy between US$6.9 billion $17.6 (£5.4 – £13.7 billion) losses expenses since 1976. Most were entire or Great Britain (97%); country-scale reporting UK's four constituent countries was Reports animal costliest ($4.7 billion), then plant ($1.3 fungal ($206.7 million) invasions. Reported damage (i.e. excluding costs) higher terrestrial ($4.8 than aquatic semi-aquatic environments ($29.8 million), primarily impacted agriculture ($4.2 billion). Invaders with earlier introduction years accrued significantly total Invasion been increasing rapidly 1976, $157.1 million (£122.1 per annum, average. Published information specific economic included only 42 520 invaders generally available most intensively studied taxa, just contributing 90% species-specific Given that many invasive lacking actively managed well-recognised impacts, this suggests is incomplete totals presented here vast underestimates owing to knowledge gaps. Financial expenditure managing fraction (37%) incurred through from invaders; greater investments research are, therefore, urgently required.
