Abstract Hybridization between invasive and native species has raised global concern, given the dramatic increase in range shifts pest outbreaks due to anthropogenic dispersal. Nevertheless, secondary contact sister lineages of local provides a natural laboratory understand factors that determine introgression maintenance or loss barriers. Here, we characterize early evolutionary outcomes following Helicoverpa armigera H. zea Brazil. We carried out whole-genome resequencing moths from Brazil two temporal samples: during outbreak 2013 2017. There is evidence for burst hybridization widespread into coinciding with expansion 2013. However, armigera, admixture proportion length introgressed blocks were significantly reduced 2017, suggesting selection against admixture.

Economic costs of biological invasions within North America

NeoBiota, Journal Year: 2021, Volume and Issue: 67, P. 485 - 510

Published: July 29, 2021

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.

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 economic costs of biological invasions in Brazil: a first assessment

NeoBiota, Journal Year: 2021, Volume and Issue: 67, P. 349 - 374

Published: July 29, 2021

Biological invasions are one of the leading causes global environmental change and their impacts can affect biodiversity, ecosystem services, human health economy. Yet, understanding on invasive alien species is still limited mostly related to outbreaks losses in agricultural yield, followed by ecological natural systems. Notably, economic biological have rarely been quantified. Brazil has at least 1214 known from which 460 recognized as species. Still, there no comprehensive estimates cost impact management. Here, we aimed filling this gap providing a estimate Brazil. In order quantify these costs for species, ecosystems well-being used InvaCost database first compilation invasions. We found that reportedly spent minimum USD 105.53 billions over 35 years (1984–2019), with an average 3.02 (± 9.8) per year. Furthermore, 104.33 billion were due damages caused invaders, whereas only 1.19 invested management (prevention, control or eradication). also recorded unevenly distributed across ecosystems, socio-economic sectors, evaluated published. substantially greater than those prevention, eradication IAS. Since our data show reported 16 likely conservative actual Taken together, they indicate important cause opted paying damage incurred rather investing preventing them happening.

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.

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.

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. Across estimated peaked approximately two decades after detection, rate progression along was influenced local abiotic conditions. The S-shaped may be common among many undergo complex dynamics. provides potentially unifying approach advance could inform timely management actions mitigate ecosystems economies.

Human-induced abiotic global environmental changes (GECs) and the spread of nonnative invasive species are rapidly altering ecosystems. Understanding relative interactive effects invasion GECs is critical for informing ecosystem adaptation management, but this information has not been synthesized. We conducted a meta-analysis to investigate invasions, GECs, their combined influences on native found 458 cases from 95 published studies that reported individual invasions GEC stressor, which was most commonly warming, drought, or nitrogen addition. calculated standardized effect sizes (Hedges’ d) treatments classified interactions as additive (sum treatment effects), antagonistic (smaller than expected), synergistic (outside expected range). The ecological varied, with detrimental more likely drought other GECs. Invasions were strongly detrimental, average, Invasion mostly antagonistic, occurred in >25% led outcomes While often smaller effects, synergisms rare across responses scale. Overall, between typically no worse alone, highlighting importance managing locally crucial step toward reducing harm multiple changes.
