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.

Socio‐economic impact classification of alien taxa (SEICAT)

Methods in Ecology and Evolution, Год журнала: 2017, Номер 9(1), С. 159 - 168

Опубликована: Июль 31, 2017

Abstract Many alien taxa are known to cause socio‐economic impacts by affecting the different constituents of human well‐being (security; material and non‐material assets; health; social, spiritual cultural relations; freedom choice action). Attempts quantify in monetary terms unlikely provide a useful basis for evaluating comparing because they notoriously difficult measure important aspects ignored. Here, we propose novel standardised method classifying magnitude their on well‐being, based capability approach from welfare economics. The core characteristic this is that it uses changes peoples' activities as common metric well‐being. Impacts assigned one five levels, Minimal Concern Massive, according semi‐quantitative scenarios describe severity impacts. Taxa then classified highest level deleterious impact have been recorded any constituent scheme also includes categories not evaluated, no population, or data deficient, assigning uncertainty all classifications. To demonstrate utility system, amphibians globally.

Prioritizing species, pathways, and sites to achieve conservation targets for biological invasion

Biological Invasions, Год журнала: 2015, Номер 18(2), С. 299 - 314

Опубликована: Ноя. 21, 2015

Prioritization is indispensable for the management of biological invasions, as recognized by Convention on Biological Diversity, its current strategic plan, and specifically Aichi Target 9 that concerns invasive alien species. Here we provide an overview process, approaches data needs prioritization invasion policy management, with intention informing guiding efforts to address this target. Many schemes quantify impact risk, from pragmatic action-focused data-demanding science-based. Effective must consider not only species pathways (as mentioned in 9), but also which sites are most sensitive susceptible (not made explicit 9). Integrated across these foci may lead future efficiencies resource allocation management. countries face challenge prioritizing little capacity poor baseline data. We recommend a consultative, science-based process impacts based species, sites, outline information needed achieve this. This should be integrated into national incorporates broad suite social economic criteria. Such likely feasible countries.

A vision for global monitoring of biological invasions

Biological Conservation, Год журнала: 2016, Номер 213, С. 295 - 308

Опубликована: Июнь 29, 2016

Managing biological invasions relies on good global coverage of species distributions. Accurate information alien distributions, obtained from international policy and cross-border co-operation, is required to evaluate trans-boundary trading partnership risks. However, a standardized approach for systematically monitoring tracking still lacking. This Perspective presents vision observation invasions. We show how the architecture provided by minimum set Essential Variables, collaboration data sharing infrastructure, strategic contributions countries. this novel, synthetic an system provides tangible attainable solution delivering needed slow rate new incursions reduce impacts invaders. identify three Variables Invasion Monitoring; occurrence, status impact. outline delivery joint, complementary countries community initiatives possible. Country are made feasible using modular where all able participate strategically build their over time. The we will deliver wide-ranging benefits efforts minimize environmental impacts. These accrue time as increases.

Introducing the Global Register of Introduced and Invasive Species

Scientific Data, Год журнала: 2018, Номер 5(1)

Опубликована: Янв. 23, 2018

Abstract Harmonised, representative data on the state of biological invasions remain inadequate at country and global scales, particularly for taxa that affect biodiversity ecosystems. Information is not readily available in a form suitable policy reporting. The Global Register Introduced Invasive Species (GRIIS) provides first country-wise checklists introduced (naturalised) invasive species. GRIIS was conceived to provide sustainable platform information delivery support national governments. We outline rationale methods underpinning GRIIS, facilitate transparent, repeatable analysis Twenty are presented as exemplars; Checklists close all countries globally will be submitted through same process shortly. Over 11000 species records currently 20 exemplars alone, with environmental impact evidence just over 20% these. significant identify prioritise alien species, establishes baselines. In future this enable system monitoring trends environment.

Four priority areas to advance invasion science in the face of rapid environmental change

Environmental Reviews, Год журнала: 2020, Номер 29(2), С. 119 - 141

Опубликована: Дек. 7, 2020

Unprecedented rates of introduction and spread non-native species pose burgeoning challenges to biodiversity, natural resource management, regional economies, human health. Current biosecurity efforts are failing keep pace with globalization, revealing critical gaps in our understanding response invasions. Here, we identify four priority areas advance invasion science the face rapid global environmental change. First, should strive develop a more comprehensive framework for predicting how behavior, abundance, interspecific interactions vary relation conditions receiving environments these factors govern ecological impacts invasion. A second is understand potential synergistic effects multiple co-occurring stressors— particularly involving climate change—on establishment impact species. Climate adaptation mitigation strategies will need consider possible consequences promoting species, appropriate management responses be developed. The third address taxonomic impediment. ability detect evaluate risks compromised by growing deficit expertise, which cannot adequately compensated new molecular technologies alone. Management become increasingly challenging unless academia, industry, governments train employ personnel taxonomy systematics. Fourth, recommend that internationally cooperative bridgehead dispersal networks, organisms tend invade regions from locations where they have already established. Cooperation among countries eradicate or control established yield greater benefit than independent attempts individual exclude arriving establishing.

The redclaw crayfish: A prominent aquaculture species with invasive potential in tropical and subtropical biodiversity hotspots

Reviews in Aquaculture, Год журнала: 2021, Номер 13(3), С. 1488 - 1530

Опубликована: Янв. 12, 2021

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
