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.

Alien species form one of the main threats to global biodiversity. Although Life Cycle Assessment attempts holistically assess environmental impacts products and services across value chains, ecological introduction alien are so far not assessed in Impact Assessment. Here, we developed country-to-country-specific characterization factors, expressed as time-integrated potentially disappeared fraction (PDF; regional global) native terrestrial due introductions per unit goods transported [kg] between two countries. The factors were generated by analyzing data on first records species, distributions, their threat status, well bilateral trade partnerships from 1870–2019. resulting vary over several orders magnitude, indicating that impact greatly varies transportation route trading partner.

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.

Global flows of insect transport and establishment: The role of biogeography, trade and regulations

Diversity and Distributions, Journal Year: 2023, Volume and Issue: 29(11), P. 1478 - 1491

Abstract Aim Non‐native species are part of almost every biological community worldwide, yet numbers establishments have an uneven global distribution. Asymmetrical exchanges between regions likely influenced by a range mechanisms, including propagule pressure, native pools, environmental conditions and biosecurity. While the importance different mechanisms is to vary among invasion stages, those occurring prior establishment (transport introduction) difficult account for. We used records unintentional insect introductions test (1) whether insects from some biogeographic more be successful invaders, (2) intensity trade flows determines how many intercepted successfully establish, (3) variables driving transport differ. Location Canada, mainland USA, Hawaii, Japan, Australia, New Zealand, Great Britain, South Korea, Africa. Methods To disentangle processes during we analysed border interceptions 8199 as proxy for transported flows, lists 2076 established non‐native in eight areas. investigated influence variables, socio‐economic biosecurity regulations on size regions.

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.

Non-native ants are breaking down biogeographic boundaries and homogenizing community assemblages

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: March 13, 2024

Abstract As geographic distance increases, species assemblages become more distinct, defining global biogeographic realms with abrupt boundaries. Yet, it remains largely unknown to what extent these may change because of human-mediated dispersal species. Focusing on the distributions 309 non-native ant species, we show that historical patterns have already broken down into tropical versus non-tropical regions. Importantly, demonstrate profound changes are not limited distribution ants but fundamentally alter boundaries all biodiversity (13,774 species). In total, 52% similar, supporting a trend biotic homogenization. Strikingly, this was strongest islands and in tropics, which harbor some most vulnerable ecosystems.

Abstract Information on the determinants of taxonomic and phylogenetic diversity invasive plant species is crucial for managing plants. With globalization, most countries have experienced substantial economic losses environmental damage due to biological invasions. We analysed variation in structure plants among worldwide. To do so, we used a comprehensive checklist 152 worldwide calculate (i.e. Faith’s PD metric) structure, using mean distance (MPD) nearest taxon (MNTD). then combined these data minimum adequate models with geographic, climatic, socio‐economic international trade variables. also conducted randomization tests determine whether was clustered or overdispersed. Taxonomic exhibited spatial congruence. were positively correlated insularity, annual precipitation (MAP) HS‐12 (seeds, grains medicinal plants) import values per capita, but negatively associated temperature (MAT) HS‐07 (vegetables) evenness. In addition, increased airport density, evenness lower HS‐08 (fruit nuts) imports. MPD greater land area density fewer exporting source countries. MNTD MAT declined insularity. Phylogenetic clustering occurred 28.9%–49.3% countries, whereas overdispersion rare, observed only 0.6%–5.3% Synthesis . Our study reveals that shaped by socio‐economic, climatic factors. Nearly one‐third showed species, indicating relatively consistent global pattern. These findings underscore importance integrating both perspectives invasion ecology, emphasizing need regionally tailored management strategies effectively account regional trade‐related factors mitigate future
