Abstract Adaptation is the central feature and leading explanation for evolutionary diversification of life. also notoriously difficult to study in nature, owing its complexity logistically prohibitive timescale. Here, we leverage extensive contemporary historical collections Ambrosia artemisiifolia —an aggressively invasive weed primary cause pollen-induced hayfever—to track phenotypic genetic causes recent local adaptation across native ranges North America Europe, respectively. Large haploblocks—indicative chromosomal inversions—contain a disproportionate share (26%) genomic regions conferring parallel climates between ranges, are associated with rapidly adapting traits, exhibit dramatic frequency shifts over space time. These results highlight importance large-effect standing variants rapid adaptation, which have been critical A. ’s global spread vast climatic gradients.

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.

Climate warming can reduce biocontrol efficacy and promote plant invasion due to both genetic and transient metabolomic changes

Ecology Letters, Journal Year: 2022, Volume and Issue: 25(6), P. 1387 - 1400

Published: April 5, 2022

Climate change may affect plant-herbivore interactions and their associated ecosystem functions. In an experimental evolution approach, we subjected replicated populations of the invasive Ambrosia artemisiifolia to a combination simulated warming herbivory by potential biocontrol beetle. We tracked genomic metabolomic changes across generations in field assessed plant offspring phenotypes common environment. Using integrated Bayesian model, show that increased biomass response arose through genetic composition populations. contrast, resistance shift profiles without changes, most likely transgenerational induction defences. Importantly, while was costly at ambient temperatures, removed this constraint favoured both vigorous better defended plants under biocontrol. thus decrease efficiency promote invasion, with potentially serious economic health consequences.

Foliar herbivory‐enhanced mycorrhization is associated with increased levels of lipids in root and root exudates

Journal of Ecology, Journal Year: 2024, Volume and Issue: 112(4), P. 701 - 716

Abstract Insect herbivory can affect interactions between plants and arbuscular mycorrhizal (AM) fungi through herbivore‐modified root carbon pools, while the specific metabolic changes underlying fungal responses to are poorly understood. Here we explored impacts of foliar mechanical wounding on AM colonisation community composition common ragweed ( Ambrosia artemisiifolia ) role metabolites in mediating these effects.

Specialist reassociation and residence time modulate the evolution of defense in invasive plants: A meta‐analysis

Ecology, Journal Year: 2024, Volume and Issue: 105(3)

Published: Jan. 25, 2024

Abstract Invasive plants typically escape specialist herbivores but are often attacked by generalist in their introduced ranges. The shifting defense hypothesis suggests that this will cause invasive to evolve lower resistance against specialists, higher generalists, and greater tolerance herbivore damage. However, the duration direction of selective pressures can shape evolutionary responses for plants. Two critical factors (1) residence time (length an species has been its range) (2) reassociation (attack purposely or accidentally specialists). Yet, these two have not considered simultaneously previous quantitative syntheses. Here, we performed a meta‐analysis with 367 effect sizes from 70 studies 35 plant native populations. We tested how ranges affected defenses specialists including traits (physical barriers, digestibility reducers toxins), effects (performance damage caused generalists) (from generalists). found each significantly altered reducers, performance, damage, Furthermore, strongly toxins respectively. When restricted consideration both longer times no populations had similar types, compared conclude pressure Under long‐term (long time) stable (no reassociation) pressure, generally decrease increase provides mixed support hypothesis.

Eco‐Evolutionary Dynamics of Plant–Soil Feedbacks Explain the Spread Potential of a Plant Invader Under Climate Warming and Biocontrol Herbivory

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Plant-soil feedbacks (PSFs) can contribute to the success of invasive plants. Despite strong evidence that plant genetic traits influence soil microbial communities and vice versa, empirical exploring these over evolutionary timescales, especially under climate change, remains limited.
