ABSTRACT Weed communities influence the dynamics of ecosystems, particularly in disturbed environments where anthropogenic activities often result higher pollution. Understanding existing between native weed and invasive species is crucial for effective management normal ecosystem functioning. Recognising potential resistance to invasion can help identify suitable plants restoration operations. This review aims investigate adaptations exhibited by non‐native weeds that may affect invasions within environments.

Bridgehead effect and multiple introductions shape the global invasion history of a termite

Published: Feb. 12, 2021

Abstract Native to eastern Asia, the Formosan subterranean termite Coptotermes formosanus (Shiraki) is recognized as one of 100 worst invasive pests in world, with established populations Japan, Hawaii and southeastern United States. Despite its importance, native source(s) C. introductions their pathway out Asia remain elusive. Using ~22,000 SNPs, we retraced invasion history this species through approximate Bayesian computation assessed consequences on genetic patterns demography. We show a complex history, where an initial introduction resulted from two distinct events Hong Kong region. The admixed Hawaiian population subsequently served source, bridgehead, for US. A separate event southcentral China occurred Florida showing admixture first introduction. Overall, these findings further reinforce pivotal role bridgeheads shaping distributions Anthropocene illustrate that global distribution has been shaped by multiple China, which may have prevented possibly reversed loss diversity within range.

Rapid and Repeated Climate Adaptation Involving Chromosome Inversions following Invasion of an Insect

Molecular Biology and Evolution, Journal Year: 2024, Volume and Issue: 41(3)

Published: Feb. 24, 2024

Abstract Following invasion, insects can become adapted to conditions experienced in their invasive range, but there are few studies on the speed of adaptation and its genomic basis. Here, we examine a small insect pest, Thrips palmi, following contemporary range expansion across sharp climate gradient from subtropics temperate areas. We first found geographically associated population genetic structure inferred stepping-stone dispersal pattern this pest open fields southern China greenhouse environments northern regions, with limited gene flow after colonization. In common garden experiments, both field groups exhibited clinal patterns thermal tolerance as measured by critical maximum (CTmax) closely linked latitude temperature variables. A selection experiment reinforced evolutionary potential CTmax an estimated h2 6.8% for trait. identified 3 inversions genome that were CTmax, accounting 49.9%, 19.6%, 8.6% variance among populations. Other variations outside inversion region specific certain populations functionally conserved. These findings highlight rapid reiterate importance behaving large-effect alleles adaptation.

The genomic secrets of invasive plants

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

Summary Genomics has revolutionised the study of invasive species, allowing evolutionary biologists to dissect mechanisms invasion in unprecedented detail. Botanical research played an important role these advances, driving much what we currently know about key determinants success (e.g. hybridisation, whole‐genome duplication). Despite this, a comprehensive review plant genomics been lacking. Here, aim address this gap, highlighting recent discoveries that have helped progress field. For example, by leveraging natural and experimental populations, botanical confirmed importance large‐effect standing variation during adaptation species. Further, genomic investigations plants are increasingly revealing large structural variants, as well genetic changes induced duplication such redundancy or breakdown dosage‐sensitive reproductive barriers, can play adaptive evolution invaders. However, numerous questions remain, including when chromosomal inversions might help hinder invasions, whether gene reuse is common epigenetically mutations underpin plasticity populations. We conclude other outstanding studies poised answer.

Trait Evolution in Invasive Species

Annual Plant Reviews online, Journal Year: 2018, Volume and Issue: unknown, P. 459 - 496

Published: Aug. 14, 2018

Abstract One of the most exciting recent developments in field invasion biology has been growing realisation that evolution can determine invasive species' success. Here, we review research on contemporary populations, with a focus traits have potential to contribute spread. Evidence available so far indicates adaptive divergence quantitative predominates, although contribution non‐adaptive processes should not be easily discounted. Further, populations appears more frequently spurred by abiotic factors, rather than escape from natural enemies. Important progress remains made role hybridisation success, or conditions under which rapid phenotypic plasticity at key leads invasions. Also, do yet firm grasp how often expansion load limits While convincing examples adaptation along geographic climatic gradients are available, highlight such clines would arise irrespective biotic conditions. We propose potentially important future lines investigation illuminate mechanistic basis success while maximising value species for understanding evolutionary processes.
