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. Factors such as ecological characteristics, altered soil conditions, potentially confer a competitive advantage relative or are analysed. Moreover, roles biotic interactions competition, mutualistic relationships, allelopathy shaping described. Emphasis given consideration key factor provides insights conservation efforts Additionally, this underscores need further research unravel underlying mechanisms devise targeted strategies. These strategies aim promote mitigate negative effects By delving deeper into these insights, we gain an understanding ecosystems develop valuable species, restore long‐term sustainability.

Summary Biological invasions provide opportunities to study evolutionary processes occurring over contemporary timescales. To explore the speed and repeatability of adaptation, we examined divergence life‐history traits climate, using latitude as a proxy, in native North American introduced European Australian ranges annual plant Ambrosia artemisiifolia . We explored niche changes following introductions climate dynamic models. In common garden, trait by growing seeds collected across three with highly distinct demographic histories. Heterozygosity–fitness associations were used effect invasion history on potential success. accounted for nonadaptive population differentiation 11 598 single nucleotide polymorphisms. revealed centroid shift warmer, wetter climates ranges. identified repeated latitudinal traits, populations positioned at either end clines.

Abstract Understanding how introduced species succeed and become widely distributed within non‐native areas is critical to reduce the threats posed by them. Our goal was reconstruct main invasion routes dynamics of a global freshwater invader, red swamp crayfish, Procambarus clarkii , through analysis its genetic variability in both native invasive ranges. We inferred population structure from fragment (608 base pairs) mitochondrial marker cytochrome c oxidase subunit I 1,062 individuals P. addition 354 GenBank sequences, for total 122 populations (22 natives 100 invaded). Genetic assessed using molecular variance non‐metric multidimensional scaling analyses. analysed haplotype frequencies each locality region. The network depicted Pop ART software. A high diversity found range (haplotype [Hd]: 0.90), but also some areas, such as western U.S.A.

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

Communications Biology, Год журнала: 2021, Номер 4(1)

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, Год журнала: 2024, Номер 41(3)

Опубликована: Фев. 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.

Trait Evolution in Invasive Species

Annual Plant Reviews online, Год журнала: 2018, Номер unknown, С. 459 - 496

Опубликована: Авг. 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.
