Historical plant introductions predict current insect invasions

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(24)

Published: June 5, 2023

Thousands of insect species have been introduced outside their native ranges, and some them strongly impact ecosystems human societies. Because a large fraction insects feed on or are associated with plants, nonnative plants provide habitat resources for invading insects, thereby facilitating establishment. Furthermore, plant imports represent one the main pathways accidental introductions. Here, we tested hypothesis that invasions precede promote invasions. We found geographical variation in current flows was best explained by dating back to 1900 rather than more recent flows. Interestingly, were better predictor potentially confounding socioeconomic variables. Based observed time lag between invasions, estimated global invasion debt consists 3,442 region-level introductions, representing potential increase 35% This most important Afrotropics, Neotropics, Indomalaya, where expect 10 20-fold discoveries new species. Overall, our results highlight strong link show limiting spread might be key preventing future both insects.

Alien insect dispersal mediated by the global movement of commodities

Abstract Globalization and economic growth are recognized as key drivers of biological invasions. Alien species have become a feature almost every community worldwide, rates new introductions continue to rise the movement people goods accelerates. Insects among most numerous problematic alien organisms, mainly introduced unintentionally with imported cargo or arriving passengers. However, processes occurring prior insect remain poorly understood. We used unique dataset 1,902,392 border interception records from inspections at air, land, maritime ports in Australia, New Zealand, Europe, Japan, USA, Canada identify commodities associated through trade travel. In total, 8939 were intercepted, commodity association data available for 1242 recorded between 1960 2019. rarefaction extrapolation methods estimate total richness diversity different types.

More closely related tended share similar associations, but this occurred largely genus level rather than orders families. These similarities genera can potentially inform pathway management species.

Global proliferation of nonnative plants is a major driver of insect invasions

BioScience, Journal Year: 2024, Volume and Issue: 74(11), P. 770 - 781

Published: Oct. 18, 2024

Abstract Invasions by nonnative insect species can massively disrupt ecological processes, often leading to serious economic impacts. Previous work has identified propagule pressure as important driver of the trend increasing numbers invasions worldwide. In present article, we propose an alternative hypothesis—that are being driven proliferation plants, which create niches for specialists and facilitate their establishment outside native ranges where hosts planted or invasive. We synthesize mechanisms plant invasions, macroecological patterns supporting tight link between case studies having facilitated subsequent establishment. This body evidence indicates that a major invasions. Consequently, benefits limiting spread plants include averting insects spillover onto species.

Forecasting potential invaders to prevent future biological invasions worldwide

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(7)

Abstract The ever‐increasing and expanding globalisation of trade transport underpins the escalating global problem biological invasions. Developing biosecurity infrastructures is crucial to anticipate prevent introduction invasive alien species. Still, robust defensible forecasts potential invaders are rare, especially for species without known invasion history. Here, we aim support decision‐making by developing a quantitative risk assessment tool based on syndromes (i.e., generalising typical attributes species). We implemented workflow ‘Multiple Imputation with Chain Equation’ estimate from imputed datasets species' life‐history ecological traits macroecological patterns. Importantly, our models disentangle factors explaining (i) (ii) establishment. showcase modelling 466 amphibians reptile Then, project these reptiles worldwide (16,236 [c.76% coverage]) identify being unintentionally transported introduced, establishing populations.

Investigating beetle communities in and around entry points can improve surveillance at national and international scale

Beetles are commonly moved among continents with international trade. Baited traps set up in and around entry points used to increase chances of early-detection incoming species complement visual inspections. A still underestimated benefit this surveillance approach is the high number diversity collected bycatch species. In study, we exploited a multiyear program carried out baited at five Spanish ports their surrounding natural areas investigate i) importance identifying more promptly detect nonnative belonging non-target groups; ii) patterns native richness abundance inside port vs. areas; iii) occurrence spillover events between areas, iv) whether most introduced into other countries abundant than areas. total 23,538 individuals from 206 representing 33 families were collected.

Higher tree species richness and diversity in urban areas than in forests: Implications for host availability for invasive tree pests and pathogens

Urban and forest trees provide valuable ecosystem services. However, they are increasingly threatened by invasive pests pathogens. Trees in urban areas often the first potential hosts non-native tree-feeding insects tree pathogens ("pests") encounter after introduction a novel region. If encountered suitable hosts, these can establish become – eventually also surrounding forests. Here, we compared species genus composition between forests examined implications for host availability effects on invasibility. We compiled standardised 26 inventories, containing ∼ 500.000 individual trees. used multivariate analyses to compare with from each municipality (10 km radius), derived Swiss National Forest Inventory. With > 1300 different species, richness of was 17 times higher than Linear models revealed that quarantine is significantly forests, large differences suitability assemblages.

Human-mediated transport has led to the establishment of more than 6,700 non-native insect species with wide-ranging effects on ecosystems, economies and human health. Understanding how different aspects globalization affect spread insects is crucial reducing their effects. In this Review, we explore current historical patterns, drivers dynamics global invasions facilitated by humans since prehistory. Multiple history have influenced invasion dynamics, including agricultural practices in Neolithic period, advent early empires trade routes, colonization, geopolitical events, wars economic crises. Technological innovations such as steam ships, containerization internet further accelerated invasions. Spatial patterns are characterized frequent secondary via bridgehead populations, asymmetric intercontinental flows originating disproportionally from Europe, biotic homogenization communities.
