Adaptation is a critical determinant of the diversification, persistence, and geographic range limits species. Yet genetic basis adaptation often unknown potentially underpinned by wide mutational types-from single nucleotide changes to large-scale alterations chromosome structure. Copy number variation (CNV) thought be an important source adaptive variation, as indicated decades candidate gene studies that point CNVs underlying rapid strong selective pressures. Nevertheless, population-genomic face unique logistical challenges not encountered other forms variation. Consequently, few have systematically investigated contributions at genome-wide scale. We present analysis CNV contributing invasive weed, Ambrosia artemisiifolia. show clear signatures parallel local between North American (native) European (invaded) ranges, implying widespread reuse during shared heterogeneous patterns selection. used principal component (PCA) genotype regions in whole-genome sequences samples collected over last two centuries. identified 16 large up 11.85 megabases length, eight which signals evolutionary change, with pronounced frequency shifts historic modern populations.

Abstract Imperfect historical records and complex demographic histories present challenges for reconstructing the history of biological invasions. Here, we combine records, extensive worldwide genome-wide sampling, analyses to investigate global invasion Mimulus guttatus from North America Europe Southwest Pacific. By sampling 521 plants 158 native introduced populations genotyped at >44,000 loci, determined that invasive M. was first likely British Isles Aleutian Islands (Alaska), followed by admixture multiple parts range. We hypothesise in then served as a bridgehead vanguard invasions worldwide. Our results emphasise highly admixed nature demonstrate potential serve sources secondary admixture, producing novel hybrids. Unravelling provides starting point understand how adapt environments.

Invasive species are a key driver of the global biodiversity crisis, but drivers invasiveness, including role pathogens, remain debated. We investigated genomic basis invasiveness in Ambrosia artemisiifolia (common ragweed), introduced to Europe late 19th century, by resequencing 655 ragweed genomes, 308 herbarium specimens collected up 190 years ago. In invasive European populations, we found selection signatures defense genes and lower prevalence disease-inducing plant pathogens. Together with temporal changes population structure associated introgression from closely related species, escape specific microbial enemies likely favored plant's remarkable success as an species.

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.

Invasive alien species are a significant threat to both economic and ecological systems. Identifying the processes that give rise invasive populations is essential for implementing effective control strategies. We conducted an ancestry analysis of feral swine (Sus scrofa, Linnaeus, 1758), highly destructive ungulate widely distributed throughout contiguous United States, describe introduction pathways, sources newly emergent contributing ongoing invasion. Comparisons high-density single nucleotide polymorphism genotypes 6,566 comprehensive reference set S. scrofa revealed vast majority were mixed ancestry, with dominant genetic associations Western heritage breeds domestic pig European wild boar.

Abstract Molecular identification of mixed‐species pollen samples has a range applications in various fields research. To date, such molecular primarily been carried out via amplicon sequencing, but whole‐genome shotgun (WGS) sequencing DNA potential advantages, including (1) more genetic information per sample and (2) the for better quantitative matching. In this study, we tested performance WGS methodology publicly available reference sequences identifying species quantifying their relative abundance mock communities. Using communities previously analyzed with metabarcoding, sequenced approximately 200Mbp each using Illumina HiSeq MiSeq. Taxonomic identifications were based on Kraken k ‐mer method libraries constructed from full‐genome short read archive data NCBI database. We found to be reliable taxonomic near 100% mixtures generating higher rates false positives (reads not identified correct taxon at required level) rbcL ITS2 sequencing. For quantification abundance, provided stronger correlation between grain proportion sequence proportion, diverged 1:1 relationship, likely due rate positives. Currently, limitation WGS‐based is lack representation plant diversity genome databases. As databases improve costs drop, expect that eventually genomics methods will become choice samples.

Pooled DNA sequencing parental and offspring showed that warming experienced greater divergence from their parents, than control populations. a environment, more convergent phenotypes in seven out nine traits, later flowering larger biomass, plants For both also found significantly higher ratio phenotypic differentiation across generations for populations, indicating stronger response selection conditions.

Abstract Uncovering the genomic basis of repeated adaption can provide important insights into constraints and biases that limit diversity genetic responses. Demographic processes such as admixture or bottlenecks affect variation underlying traits experiencing selection. The impact these on adaptation remains, however, largely unexamined empirically. We here test repeatability in phenotypes genotypes along parallel climatic clines within native North American introduced European Australian Ambrosia artemisiifolia ranges. To do this, we combined multiple lines evidence from phenotype‐environment associations, F ST ‐like outlier tests, genotype‐environment associations genotype‐phenotype associations. used 853 individuals grown common garden 84 sampling locations, targeting 19 phenotypes, >83 k SNPs 22 environmental variables. found 17%–26% loci with adaptive signatures were among ranges, despite alternative demographic histories shaping Our results suggest major changes occur short timescales, seemingly minimum impacts due to linked introduction. These patterns reveal some predictability evolutionary change during range expansion, key a world facing ongoing climate change, rapid invasive spread.
