Unwelcome exchange: International trade as a direct and indirect driver of biological invasions worldwide

One Earth, Journal Year: 2021, Volume and Issue: 4(5), P. 666 - 679

Published: May 1, 2021

Biological invasions are synonymous with international trade. The direct effects of trade have largely been quantified using relationships between imports and the number alien species in a region or patterns global spread linked to shipping air traffic networks. But also has an indirect role on biological by transforming environments societies exporting importing nations. Here, both roles invasions, as well their interaction, examined for first time. Future trends trade, including e-commerce, new routes, major infrastructure developments, will lead pressure national borders soon outstripping resources available intervention. current legislative scientific tools targeting insufficient deal this growing threat require mindset that focuses curbing pandemic risk posed species.

Dissecting the null model for biological invasions: A meta-analysis of the propagule pressure effect

A consistent determinant of the establishment success alien species appears to be number individuals that are introduced found a population (propagule pressure), yet variation in form this relationship has been largely unexplored. Here, we present first quantitative systematic review form, using Bayesian meta-analytical methods. The between propagule pressure and evaluated for broad range taxa life histories, including invertebrates, herbaceous plants long-lived trees, terrestrial aquatic vertebrates. We positive mean effect on feature every hypothesis tested. However, most critically depended pressures 10–100 individuals. Heterogeneity size was associated primarily with different analytical approaches, some evidence larger sizes animal rather than plant introductions. Conversely, no accounted any analysis by scale study (field global) or methodology (observational, experimental, proxy) used. Our analyses reveal remarkable consistency success.

Global trade networks determine the distribution of invasive non‐native species

Global Ecology and Biogeography, Journal Year: 2017, Volume and Issue: 26(8), P. 907 - 917

Published: June 20, 2017

Abstract Aim Although global trade is implicated in biological invasions, the assumption that networks explain large‐scale distributions of non‐native species remains largely untested. We addressed this by analysing relationships between and plant pest invasion. Location Forty‐eight countries Europe Mediterranean. Time period Current. Major taxa studied Four hundred twenty‐two pests (173 invertebrates, 166 pathogens, 83 plants). Methods Ten types connectivity index were developed, representing potential roles networks, air transport links, geographical proximity, climatic similarity source country wealth facilitating Generalized linear mixed models (GLMMs) identified best explained both historical recent Then, more complex GLMMs developed including through for multiple commodities relevant (live plants, forest products, fruit vegetables seeds) species’ associations with those commodities. Results Total import volumes, prevalence measures based on transport, distance or climate did not invasion as well networks. Invasion was strongly promoted agricultural imports from which focal present climatically similar to importing country. However, live nearby provided a better explanation most invasions.

Prospects and challenges of implementing DNA metabarcoding for high-throughput insect surveillance

GigaScience, Journal Year: 2019, Volume and Issue: 8(8)

Published: July 30, 2019

Abstract Trap-based surveillance strategies are widely used for monitoring of invasive insect species, aiming to detect newly arrived exotic taxa as well track the population levels established or endemic pests. Where these traps have low specificity and capture non-target species in excess target pests, need extensive specimen sorting identification creates a major diagnostic bottleneck. While recent development standardized molecular diagnostics has partly alleviated this requirement, single per reaction nature methods does not readily scale sheer number insects trapped programmes. Consequently, lists often restricted few high-priority allowing unanticipated avoid detection potentially establish populations. DNA metabarcoding recently emerged method conducting simultaneous, multi-species complex mixed communities may lend itself ideally rapid bulk trap samples. Moreover, high-throughput sequencing platforms could enable multiplexing hundreds diverse samples on flow cell, thereby providing means dramatically up terms both quantity that can be processed concurrently pest targeted. In review literature, we explore how tailored context highlight unique technical regulatory challenges must considered when implementing technologies into sensitive applications.

Disentangling the abundance–impact relationship for invasive species

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(20), P. 9919 - 9924

Published: April 29, 2019

To predict the threat of biological invasions to native species, it is critical that we understand how increasing abundance invasive alien species (IAS) affects populations and communities. The form this relationship across taxa ecosystems unknown, but expected depend strongly on trophic position IAS relative species. Using a global metaanalysis based 1,258 empirical studies presented in 201 scientific publications, assessed shape, direction, strength responses invader abundance. We also tested varied with for at population vs. community levels. As increased, declined nonlinearly by 20%, average, metrics linearly 25%. When higher levels, invaders tended cause strong, nonlinear decline communities, greatest impacts occurring low In contrast, same level linear while lower levels had no consistent impacts. At level, significantly larger effects evenness diversity than richness. Our results show invasion critically species’ position. Further, these general abundance–impact relationships reveal are likely develop during process when best manage them.

From eDNA to citizen science: emerging tools for the early detection of invasive species

Frontiers in Ecology and the Environment, Journal Year: 2020, Volume and Issue: 18(4), P. 194 - 202

Published: Feb. 3, 2020

Biological invasions are a form of global change threatening biodiversity, ecosystem stability, and human health, cost government agencies billions dollars in remediation eradication programs. Attempts to eradicate introduced species most successful when detection newly established populations occurs early the invasion process. We review existing emerging tools – specifically environmental DNA ( eDNA ), chemical approaches, remote sensing, citizen science, agency‐based monitoring for surveillance invasive species. For each tool, we consider benefits provided, examine challenges limitations, discuss data sharing integration, suggest best practice implementations Programs that promote public participation large‐scale biodiversity identification (such as iN aturalist eB ird) may be resources detection. However, from these platforms must monitored used by can mount appropriate response efforts. Control efforts more likely succeed they focused on prevention, thereby saving considerable time resources.

Niche Breadth: Causes and Consequences for Ecology, Evolution, and Conservation

The Quarterly Review of Biology, Journal Year: 2020, Volume and Issue: 95(3), P. 179 - 214

Published: Sept. 1, 2020

Niche breadth is a unifying concept spanning diverse aspects of ecology, evolution, and conservation biology. usually refers to the diversity resources used or environments tolerated by an individual, population, species, clade. Here we review key research in biology light niche breadth. Namely, explore role shaping geographic distributions species richness from local landscape scales, how evolves influences lineage diversification, its use for understanding invasions, responses climate change, vulnerability extinction, ecosystem functioning. This literature informs agenda that identifies focused needs further progress: testing hierarchical nature (e.g., individuals, populations, species); quantifying correlations among different axes environmental drivers organismal constraints generating these correlations; evaluating factors decouple fundamental realized niches. We describe this could help unify disparate subdisciplines shed on questions conservation.
