Scientists' warning on invasive alien species

ABSTRACT Biological invasions are a global consequence of an increasingly connected world and the rise in human population size. The numbers invasive alien species – subset that spread widely areas where they not native, affecting environment or livelihoods increasing. Synergies with other changes exacerbating current facilitating new ones, thereby escalating extent impacts invaders. Invasions have complex often immense long‐term direct indirect impacts. In many cases, such become apparent problematic only when invaders well established large ranges. Invasive break down biogeographic realms, affect native richness abundance, increase risk extinction, genetic composition populations, change animal behaviour, alter phylogenetic diversity across communities, modify trophic networks. Many also ecosystem functioning delivery services by altering nutrient contaminant cycling, hydrology, habitat structure, disturbance regimes. These biodiversity accelerating will further future. Scientific evidence has identified policy strategies to reduce future invasions, but these insufficiently implemented. For some nations, notably Australia New Zealand, biosecurity national priority. There been successes, as eradication rats cats on islands biological control weeds continental areas. However, countries, receive little attention. Improved international cooperation is crucial biodiversity, services, livelihoods. Countries can strengthen their regulations implement enforce more effective management should address interact invasions.

Drivers of future alien species impacts: An expert‐based assessment

Global Change Biology, Journal Year: 2020, Volume and Issue: 26(9), P. 4880 - 4893

Published: July 14, 2020

Abstract Understanding the likely future impacts of biological invasions is crucial yet highly challenging given multiple relevant environmental, socio‐economic and societal contexts drivers. In absence quantitative models, methods based on expert knowledge are best option for assessing invasion trajectories. Here, we present an assessment drivers potential alien species under contrasting scenarios socioecological through mid‐21st century. Based responses from 36 experts in invasions, moderate (20%–30%) increases compared to current conditions, expected cause major biodiversity most contexts. Three main invasions—transport, climate change change—were predicted significantly affect even a best‐case scenario. Other (e.g. human demography migration tropical subtropical regions) were also high importance specific global individual taxonomic groups or biomes). We show that some can substantially reduce invasions. However, rapid comprehensive actions necessary use this achieve goals Post‐2020 Framework Convention Biological Diversity.

Deliberate introduction of invisible invaders: A critical appraisal of the impact of microbial inoculants on soil microbial communities

Soil Biology and Biochemistry, Journal Year: 2020, Volume and Issue: 148, P. 107874 - 107874

Published: June 25, 2020

Non-target effects of deliberately released organisms into a new environment are great concern due to their potential impact on the biodiversity and functioning ecosystems. Whereas these studies often focus invasive species macro-organisms, use microbial inoculants is expected have specific particular functions but negligible overall resident communities. Here, we posit that such introductions native communities, which might influence ecosystem processes. Focusing soil used literature search examine inoculation (often release beneficial microorganisms in agricultural systems) Of 108 analyzed, 86% showed modify communities short or long term. In addition, for analyzing consequences longer term, 80% did not observe resilience (return initial state) community following inoculation. Through knowledge gathered from each study, propose synthetic mechanistic framework explaining how may alter We also identify challenges as well future approaches shed more light this unseen reality.

Developing a list of invasive alien species likely to threaten biodiversity and ecosystems in the European Union

Global Change Biology, Journal Year: 2018, Volume and Issue: 25(3), P. 1032 - 1048

Abstract The European Union ( EU ) has recently published its first list of invasive alien species IAS concern to which current legislation must apply. comprises known pose great threats biodiversity and needs be maintained updated. Horizon scanning is seen as critical identify the most threatening potential that do not yet occur in Europe subsequently risk assessed for future listing. Accordingly, we present a systematic consensus horizon procedure derive ranked likely arrive, establish, spread have an impact on region over next decade. approach unique continental scale examined, breadth taxonomic groups environments considered, methods data sources used. International experts were brought together address five broad thematic . For each group independently assembled lists established but potentially if introduced.

Invasive non‐native species likely to threaten biodiversity and ecosystems in the Antarctic Peninsula region

The Antarctic is considered to be a pristine environment relative other regions of the Earth, but it increasingly vulnerable invasions by marine, freshwater and terrestrial non-native species. Peninsula region (APR), which encompasses Peninsula, South Shetland Islands Orkney Islands, far most invaded part Antarctica continent. risk introduction invasive species APR likely increase with predicted increases in intensity, diversity distribution human activities. Parties that are signatories Treaty have called for regional assessments risk. In response, taxonomic experts undertook horizon scanning exercise using expert opinion consensus approaches identify present highest biodiversity ecosystems within over next 10 years. One hundred three species, currently absent APR, were identified as relevant review, 13 presenting high invading APR. Marine invertebrates dominated list flowering plants also represented; however, vertebrate thought unlikely establish year timeframe. We recommend (a) further development application biosecurity measures all stakeholders active including surveillance such those during this exercise, (b) use methodology across Antarctica. Without appropriate measures, rates introductions increase, resulting negative consequences whole continent, introduced spread due climate change increasing activity.

Preventing and controlling nonnative species invasions to bend the curve of global freshwater biodiversity loss

Environmental Reviews, Journal Year: 2023, Volume and Issue: 31(2), P. 310 - 326

Published: Jan. 11, 2023

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. Should a be introduced, however, then its early detection implementation rapid reaction measures avoid it establishing dispersing. If are unsuccessful becomes invasive, control containment minimize further spread impact. Minimizing impact includes methods reduce invader abundance such as screening invaded sites strict biosecurity dispersing neighbouring basins.
