Global threats from invasive alien species in the twenty-first century and national response capacities

Published: Aug. 23, 2016

Abstract Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, environmental changes, including climate change, facilitate establishment. Here we provide the first global, spatial analysis of terrestrial threat from in light twenty-first century evaluate national capacities to prevent manage invasions. We find that one-sixth global land surface is highly vulnerable invasion, substantial areas developing economies hotspots. The dominant invasion vectors differ between high-income countries (imports, particularly plants pets) low-income (air travel). Uniting data on causes introduction establishment can improve early-warning eradication schemes. Most have limited capacity act against In particular, reveal a clear need for proactive strategies with high poverty levels, low historical levels invasion.

Developing a framework of minimum standards for the risk assessment of alien species

Journal of Applied Ecology, Journal Year: 2017, Volume and Issue: 55(2), P. 526 - 538

Abstract Biological invasions are a threat to biodiversity, society and the economy. There is an urgent need provide evidence‐based assessments of risks posed by invasive alien species ( IAS ) prioritize action. Risk underpin policies in many ways: informing legislation; providing justification restrictions trade or consumer activities; prioritizing surveillance rapid response. benefits ensuring consistency content risk globally, this can be achieved framework minimum standards as checklist for quality assurance. From review existing assessment protocols, with reference requirements EU Regulation on (1143/2014) international agreements including World Trade Organisation, Convention Diversity International Plant Protection Convention, coupled consensus methods, we identified agreed upon 14 (attributes) risk‐assessment scheme should include. The were follows: (1) basic description; (2) likelihood invasion; (3) distribution, spread impacts; (4) introduction pathways; (5) impacts biodiversity ecosystems; (6) Assessment impact ecosystem services; (7) socio‐economic (8) consideration status (threatened protected) habitat under threat; (9) effects future climate change; (10) completion possible even when there lack information; (11) documents information sources; (12) provides summary consistent interpretable form; (13) includes uncertainty; (14) In deriving these standards, gaps knowledge required completing scope protocols revealed, most notably relation assessing benefits, services but also inclusion change.

Different facets of the same niche: Integrating citizen science and scientific survey data to predict biological invasion risk under multiple global change drivers

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(19), P. 5509 - 5523

Published: Aug. 7, 2023

Abstract Citizen science initiatives have been increasingly used by researchers as a source of occurrence data to model the distribution alien species. Since citizen presence‐only suffer from some fundamental issues, efforts made combine these with those provided scientifically structured surveys. Surprisingly, only few studies proposing integration evaluated contribution this process effective sampling species' environmental niches and, consequently, its effect on predictions new time intervals. We relied niche overlap analyses, machine learning classification algorithms and ecological models compare ability scientific surveys, along their integration, in capturing realized 13 invasive species Italy. Moreover, we assessed differences current future invasion risk predicted each set under multiple global change scenarios. showed that surveys captured similar though highlighting exclusive portions associated clearly identifiable conditions.

Coordinated species importation policies are needed to reduce serious invasions globally: The case of alien bumblebees in South America

Abstract The global trade of species promotes diverse human activities but also facilitates the introduction potentially invasive into new environments. As ignore national boundaries, unilateral decisions concerning set stage for transnational invasion with significant conservation, economic and political consequences. need a coordinated approach to importation policies is demonstrated by two bumblebee Chile crop pollination, despite Argentina banning commercial alien bumblebees based on expert opinion. large garden bumblebee, Bombus ruderatus , was first introduced in 1982, buff‐tailed terrestris has been continually since 1997 as part burgeoning trade.

Assessing the environmental impacts of invasive alien plants: a review of assessment approaches

NeoBiota, Journal Year: 2019, Volume and Issue: 43, P. 69 - 99

Published: March 15, 2019

Assessing the impacts of alien plant species is a major task in invasion science and vitally important for supporting invasion-related policies. Since 1993, range assessment approaches have been developed to support decisions on introduction or management species. Here we review extent which assessments (27 approaches) appraised following: (i) different types environmental impacts, (ii) context dependence (iii) prospects successful management, (iv) transparency methods criteria, underlying values terminology. While nearly all covered effects, changes genetic diversity incorporation relevant impact parameters were less likely be included. Many considered by incorporating information about actual potential However, only few went further identified resources conservation concern might affected specific Only some acknowledged distinguishing negative from positive considering value resources. Several directly addressed feasibility whereas factors such as availability suitable rarely considered. Finally, disclosed, definitions value-laden controversial terms often lacking. We conclude that despite progress assessing manifold facets opportunities remain developing approaches. These can improve results their acceptance

Published: June 23, 2020

The recognition that invasive alien species (IAS) are among the greatest threats to biodiversity has stimulated a growing interest in their impacts on native amphibians. Here we describe multifaceted consequences of biological invasions amphibians and identify potential mechanisms strategies could better enable long-term persistence species. IAS can influence amphibian fitness, population size, community structure via multiple pathways exert major, direct through predation, competition, hybridization. indirect impacts, too, such as habitat alteration spread emerging diseases, be particularly severe populations. Native may respond by modulating aspects behavior, morphology, or life history. Nevertheless, it is still unclear extent which phenotypic plasticity rapid evolution help withstand invaded communities. Practical management focused prevention, monitoring, early control most effective approaches allay should prioritized proactive conservation plans. Eradications mitigation approaches, become established, feasible greatly improve status
