Abstract The escalating global movement of alien species, facilitated by increased trade and travel, poses a pressing need to comprehend their invasive potential the consequent ecological economic ramifications. Despite growing body evidence on rapid evolutionary shifts in comprehensive insights into genetic variability underlying these adaptations are constrained limited genomic resources. Understanding role variation success or failure biological invaders is thus crucial. This study...

Invasive plants often experience rapid changes in biological interactions by escaping from their original herbivores at new habitats, and sometimes re‐associating with those afterwards. However, little is known about whether the temporal herbivorous impact work as a selective agent for defensive traits of invaded plants. Solidago altissima (goldenrod) North American perennial that has widely abandoned fields Japan. Recently, an insect Corythucha marmorata (lace bug), exotic also America,...

Increased ungulate browsing has altered the composition of plant communities and food webs forest ecosystems in many regions around world. To evaluate cascading impact deer on pollination reproduction is critical to understand roles species interactions maintaining populations for conservation management. In this study, we investigated relationships among floral resources understory herbaceous plants, pollinator visitation, fruit set shrub based data accumulation over three years six...

Geographic variation in the traits of a species is shaped by abiotic conditions, biotic interactions, and evolutionary history its interactions with other species. We studied geographic density lace bug, Corythucha marmorata, resistance tall goldenrod Solidago altissima to bug herbivory their native range United States invaded Japan. conducted field surveys reciprocal transplant experiments examine what factors influence density, ecological predict host plant between within ranges. Lace was...

Abstract Despite increasing evidence that herbivore‐mediated indirect effects play a major role in plant competition, it is unclear how and when they contribute to invasiveness. The outcomes of are primarily dependent on the environment have complex interactions with direct between plants. We evaluated Solidago altissima (Asteraceae) other co‐occurring native Asteraceae species at multiple sites range [the United States (US)] an introduced (Japan) using common garden experiments. examined...

Abstract Decreases in pollinator abundance may particularly constrain plants that lack floral rewards, since they are poor competitors for pollinators the plant community. Here, we documented pollination ecology of a rewardless orchid, Calanthe reflexa M axim., and examined effects forest understory degradation by deer browsing on success species light change neighboring flowering 2010 2011. Bombus were only at each site phenology C. did not overlap with other rewarding plants. Pollinator...

• Premise of the study: Microsatellite markers were developed in perennial herb Solidago altissima from populations within its introduced range Japan to assess population structure and facilitate tracking invasion expansion. Methods Results: Using 454 pyrosequencing, 16 microsatellite primer sets for S. . The tested on 70 individuals sampled three Japan. primers amplified di‐ trinucleotide repeats with five 25 alleles per locus, expected heterozygosity ranged 0.46 0.92. Conclusions: These...

Abstract Landscapes and vegetation are critical factors in dispersion of exotic insects expansion their range. However, few studies have addressed how the surrounding landscape affects establishment insects. We assessed relationship between an lace bug Corythucha marmorata (Uhler) northern edge bug's expanded found that bugs showed variability density among populations. Urban areas had a positive effect, while natural forest negative effect on density, with buffer range 1–2 km. Moreover,...

Abstract Plants are subjected to environmental gradients and may encounter various herbivores, leading geographic variation in defensive traits. The present review highlights that biological invasions remarkable natural experiments for studying plant–herbivore interaction tracking temporal dynamics plant defense response changes. Studies from this viewpoint can challenge general topics ecology, including the evolution of indirect interactions among plants. First, I provide a brief overview...

Abstract Many invasive plants increase aggressiveness after introduction. Since evolutionary forces such as herbivore pressure may change over different time scales, understanding the changes in biotic interactions through can clarify mechanism of their evolution aggressiveness. In this study, we examined geographic variation phenotypic traits Solidago altissima and abundance two exotic herbivorous insect species (the aphid, Uroleucon nigrotuberculatum lacebug, Corythucha marmorata), which...

Abstract The stability of plant reproductive success is dependent on the system and surrounding pollinator assemblages. Here we documented pollination ecology a shrub, Daphne miyabeana (Thymelaeaceae), that unpalatable to deer in two different habitats (open closed canopy) at site with severe browsing. We found 31.22 ± 3.07% (mean SE) 9.01 1.71% total number D. flowers become fruits open habitats, respectively. Although spontaneous selfing was possible, fruit set much lower than an...

Abstract Mass flowering (masting) has been hypothesized to be an adaptive strategy satiate florivores/granivores. However, few studies have corroborated this by examining seed predation in multiple patches of varying sizes across a wide geographical range over years. Moreover, the trophic consequences masting for parasitoids florivores/granivores and their feedback effects are poorly understood. Here, we used nationwide two bamboo species, Sasamorpha borealis var. Phyllostachys nigra...

The variability in the genetic variance-covariance (G-matrix) plant resistance and its role evolution of invasive plants have been long overlooked. We conducted an additional analysis data a reciprocal transplant experiment with tall goldenrod,

Increased ungulate browsing alters the composition of plant communities and modifies forest ecosystems worldwide. Ungulates alter their diet following changes in availability species; however, we know little about how browse selection community change with different stages deer establishment. Here, provide insight into this area study by combining multiple approaches: comparison understory community, analysis records damage, DNA barcoding sika feces at 22 sites forests northern Japan varying...

Abstract Population outbreaks of insects provide an excellent opportunity to elucidate their evolutionary history. In this study, we uncovered the phylogenetic relationships Dicraeus spp. in Japan and compared population genetic structure two bamboo-feeding spp., phyllostachyus nartshukae, by leveraging a recent nationwide mass flowering event several bamboo species Japan. We performed analysis using mitochondrial COI gene sequencing genome-wide single-nucleotide polymorphisms detected...
