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). 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 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.

ABSTRACT Standardised terminology in science is important for clarity of interpretation and communication. In invasion – a dynamic rapidly evolving discipline the proliferation technical has lacked standardised framework its development. The result convoluted inconsistent usage terminology, with various discrepancies descriptions damage interventions. A therefore needed clear, universally applicable, consistent to promote more effective communication across researchers, stakeholders, policymakers. 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. We also highlight importance conceptualising ‘spread’ classifying invasiveness ‘impact’ management. Finally, protocol dispersal mechanism, origin, population status, iv impact.

The Emergency Recovery Plan for freshwater biodiversity recognizes that addressing nonnative species is one of six principal actions needed to bend the curve in loss. This because introduction rates continue accelerate globally and where these develop invasive populations, they can have severe impacts on biodiversity. most effective management measure protect prevent introductions species.

Globalization has led to the introduction of thousands alien species worldwide. With growing impacts by invasive species, understanding invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, dynamics have been assumed follow an "invasion curve" (S-shaped curve available area invaded over time), but this dynamic lacked empirical testing using large-scale data neglects consider invader abundances. We propose "impact describing generated time based on cumulative To test curve's applicability, we used data-rich New Zealand mud snail Potamopyrgus antipodarum, one most damaging freshwater invaders that almost all Europe. Using long-term (1979-2020) abundance environmental collected across 306 European sites, observed P. antipodarum generally increased through time, with slower population growth at higher latitudes lower runoff depth. Fifty-nine percent these populations followed impact curve, characterized first occurrence, exponential growth, then saturation. This behaviour is consistent boom-bust dynamics, as saturation occurs due a rapid decline in time.

Massive economic costs of biological invasions despite widespread knowledge gaps: a dual setback for India

Biological Invasions, Год журнала: 2022, Номер 24(7), С. 2017 - 2039

Опубликована: Апрель 5, 2022

Abstract Biological invasions are one of the top drivers ongoing biodiversity crisis. An underestimated consequence is enormity their economic impacts. Knowledge gaps regarding costs produced by invasive alien species (IAS) pervasive, particularly for emerging economies such as India—the fastest growing economy worldwide. To investigate, highlight and bridge this gap, we synthesised data on IAS in India. Specifically, examine how distributed spatially, environmentally, sectorally, taxonomically, temporally, across introduction pathways; discuss Indian vary with socioeconomic indicators. We found that have cost between at least US$ 127.3 billion to 182.6 (Indian Rupees ₹ 8.3 trillion 11.9 trillion) over 1960–2020, these increased time. Despite massive recorded costs, most were not assigned specific regions, environments, sectors, types causal IAS, knowledge more pronounced India than rest world. When specifically assigned, maximum incurred West, South North India, insects semi-aquatic ecosystems; they mainly public social welfare sector, associated damages losses rather management expenses. Our findings indicate reported grossly underestimate actual especially considering expected given India’s population size, gross domestic product high numbers without costs. This analysis improves our negative impacts biological burden can represent its development. hope study motivates policymakers address socio-ecological issues launch a national invasion research programme, since growth will be accompanied greater global change.

Invasive alien species (IAS) are a major driver of global biodiversity loss, hampering conservation efforts and disrupting ecosystem functions services. While accumulating evidence documented ecological impacts IAS across geographic regions, habitat types taxonomic groups, appraisals for economic costs remained relatively sparse. This has hindered effective cost-benefit analyses that inform expenditure on management interventions to prevent, control, eradicate IAS.
