The introduction of aquatic non-indigenous species (ANS) has become a major driver for global changes in biogeography. We examined spatial patterns and temporal trends ANS detections since 1965 to inform conservation policy management.Global.We assembled an extensive dataset first records detection (1965-2015) across 49 ecosystems, including the (a) year collection, (b) population status (c) potential pathway(s) introduction. Data were analysed at regional levels assess rate, richness transport pathways.An annual mean 43 (±16 SD) primary occurred-one new every 8.4 days 50 years. rate was relatively stable during 1965-1995, but increased rapidly after this time, peaking roughly 66 per 2005-2010 then declining marginally. Detection rates variable within regions through time. Arthropods, molluscs fishes most frequently reported ANS. Most likely introduced as stowaways ships' ballast water or biofouling, although direct evidence is typically absent.This synthesis highlights magnitude recent detections, yet almost certainly represents underestimate many go unreported due limited search effort diminishing taxonomic expertise. Temporal are also confounded by reporting lags, contributing lower observed There critical need implement standardized, repeated methods taxa improve quality global-scale comparisons sustain core measures over longer time-scales. It will be fundamental fill knowledge gaps given that invasion data representing broad world's oceans not readily available maintain pipelines adaptive management.

Management priorities for marine invasive species

The Science of The Total Environment, Journal Year: 2019, Volume and Issue: 688, P. 976 - 982

Published: June 19, 2019

Managing invasive alien species is particularly challenging in the ocean mainly because marine ecosystems are highly connected across broad spatial scales. Eradication of has only been achieved when were detected early, and management responded rapidly. Generalized approaches, transferable regions, for prioritizing actions to control populations currently lacking. Here, expert knowledge was elicited prioritize 11 controlling 12 model species, distinguished by differences dispersion capacity, distribution area be managed, taxonomic identity. Each action assessed using five criteria (effectiveness, feasibility, acceptability, impacts on native communities, cost), which combined an 'applicability' metric. Raising public awareness encouraging commercial use prioritized, whereas biological considered least applicable. Our findings can guide rapid decision-making options especially at early stages invasion, reducing managers' response time critical.

Taming the terminological tempest in invasion science

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.

Historical baselines in marine bioinvasions: Implications for policy and management

PLoS ONE, Journal Year: 2018, Volume and Issue: 13(8), P. e0202383 - e0202383

Published: Aug. 16, 2018

The human-mediated introduction of marine non-indigenous species is a centuries- if not millennia-old phenomenon, but was only recently acknowledged as potent driver change in the sea. We provide synopsis key historical milestones for bioinvasions, including timelines (a) discovery and understanding invasion process, focusing on transfer mechanisms outcomes, (b) methodologies used detection monitoring, (c) approaches to ecological impacts research, (d) management policy responses. Early (until mid-1900s) bioinvasions were given little attention, number cases actively routinely facilitated. Beginning second half 20th century, several conspicuous outbreaks with strong environmental, economic, public health raised widespread concerns initiated shifts scientific perceptions. These high-profile invasions led documents strategies reduce spread species, although significant time lags limited success focused subset mechanisms. Integrated, multi-vector within an ecosystem-based context urgently needed address complex interactions natural human pressures that drive ecosystems.

Invasion syndromes: a systematic approach for predicting biological invasions and facilitating effective management

Biological Invasions, Journal Year: 2020, Volume and Issue: 22(5), P. 1801 - 1820

Published: March 2, 2020

Abstract Our ability to predict invasions has been hindered by the seemingly idiosyncratic context-dependency of individual invasions. However, we argue that robust and useful generalisations in invasion science can be made considering “invasion syndromes” which define as “a combination pathways, alien species traits, characteristics recipient ecosystem collectively result predictable dynamics impacts, managed effectively using specific policy management actions”. We describe this approach outline examples highlight its utility, including: cacti with clonal fragmentation arid ecosystems; small aquatic organisms introduced through ballast water harbours; large ranid frogs frequent secondary transfers; piscivorous freshwater fishes connected plant high-elevation areas; tall-statured grasses; tree-feeding insects forests suitable hosts. propose a systematic method for identifying delimiting syndromes. syndromes account biological while incorporating insights from comparative studies. Adopting will help structure thinking, identify transferrable risk assessment lessons, similarities among events were previously considered disparate phenomena.
