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.

Abstract Invasive plants often express above‐ground traits, such as higher growth than native plants, which promote their success. This may reflect low levels of invertebrate herbivory and/or high rates arbuscular mycorrhizal fungi (AMF) association. However, the root traits that contribute to invasive success are less well known. Moreover, combined roles herbivory, AMF, and in invasion process poorly understood. We conducted field surveys at 17 sites along a latitudinal gradient China (22.77° N 42.48° N) investigate relationships among AMF colonization, for five pairs closely related Asteraceae plant species. experimentally manipulated insect feeding two these species middle latitude (34.79°N) common garden. measured abundance, leaf damage, morphological associated with nutrient uptake, soluble sugar concentrations.

Abstract Above–belowground insect herbivore interactions and plant compensatory growth are crucial for reshaping the fitness of invasive plants, it is likely that climate warming, nitrogen (N) deposition, provenance influence this interaction in a complex way. We performed an experiment with Solidago canadensis from home introduced ranges, leaf‐chewing Spodoptera litura , root‐feeding Protaetia brevitarsis under warming N addressed how these abiotic stressors jointly shaped reciprocal effects between S. P. after herbivory. Under ambient conditions, inhibited each other on basis growth; addition or plus shifted even reversed competition depending provenance. While survival‐based above–belowground differed growth‐based ones, also neutralism amensalism detected conditions its range was more tolerant herbivory than conditions; decreased native but increased relative to conditions. These findings suggest deposition could enhance positive interactions, increasing pressures might be important mediating change host invasions.

ABSTRACT It is increasingly recognized that different genetic variants can uniquely shape their microbiomes. Invasive species often evolve in introduced ranges, but little known about the potential for microbial associations to during invasion as a result. We investigated invader genotype (G) and environment (E) interactions C. solstitialis (yellow starthistle), Eurasian plant have evolved novel genotypes, altered interactions, its severe of California, USA. conducted an experiment which native invading genotypes were inoculated with invaded range soil communities. used amplicon sequencing characterize rhizosphere bacteria both field soils from they derived. found bacterial diversity higher soils, accumulated lower unique composition experimental inoculations, relative genotypes.
