“…We also found smaller bees in sites invaded by E. canadensis which has shallow flowers, and larger and longtongued wild bees in sites invaded by A. syriaca and I. glandulifera which have large, deep flowers (see Table 1), aligning with the previously shown higher abundance of Bombus spp. in sites invaded by A. syriaca and I. glandulifera (Kovács-Hostyánszki et al, 2022;Szigeti et al, 2020).…”

“…We also found smaller bees in sites invaded by E. canadensis which has shallow flowers, and larger and long‐tongued wild bees in sites invaded by A. syriaca and I. glandulifera which have large, deep flowers (see Table 1), aligning with the previously shown higher abundance of Bombus spp. in sites invaded by A. syriaca and I. glandulifera (Kovács‐Hostyánszki et al, 2022; Szigeti et al, 2020). The phenology of the three summer‐flowering ( G. aristata , I. glandulifera , R. laciniata ) and one autumn‐flowering ( S. lanceolatum ) invasive species (Table 1), that showed floral trait dissimilarities, compared with the average phenology of the native floral communities (see the univariate calculation on mid‐flowering time, in the Table A2), may explain the dominance of hoverflies and wild bees with later mid‐flight time in invaded sites.…”

Plant invasions can lead to homogeneous communities with decreased functional diversity. However, invasive plants, with various morphological and phenological traits, may drive pollinator communities in a less predictable, more complex way. They can promote pollinators compatible with their floral traits, while leaving others without foraging resources. Our observational study on 10 invasive herbaceous species applied a traitbased approach to investigate plant invasion-driven changes in floral resources, hoverfly and bee communities. We sampled invaded and non-invaded (control) sites before and during the flowering of the invasive plants. We analysed the differences in floral traits between invasive and native plants, functional diversity and trait distributions of flower and pollinator communities between the invaded and control sites. Five invasive plant species differed from natives in floral traits. Plant invasion caused species-specific changes in functional diversity and trait distributions of communities. For instance, invaded sites had a decreased functional diversity of hoverflies before flowering of invasive species, and larger hoverflies during flowering of invasive species compared with control sites. Smaller bees were associated with invasive plants with shallow flowers, while larger and long-tongued bees were associated with two invasive species with restricted floral access. Similar to previous studies, pollinator traits showed mixed or neutral responses to plant invasion. This is probably due to the high integration capability of invasive plants into plant-pollinator systems, or limitations in sampling, trait resolution, and unrevealed environmental factors. We provide recommendations for future studies to better understand the trait-based community composition of flowering plants and pollinators.

“…From landscape to local scales, plant species play a fundamental role in animal conservation and this can be true even for invasive species, which can have in certain instances neutral and positive effects on animal species (Houlahan and Findlay, 2004;Szigeti et al, 2020). Jain et al showed that tropical butterfly populations of Singapore were highly dependent on non-native host plants.…”

Ground-nesting bees are susceptible to disturbances that affect foraging resources, vegetation structure and soil characteristics. We studied the effects of 12 invasive alien plant species on environmental variables and directly on ground-nesting bees to reveal their specific importance. We sampled bees along transects; flowers, vegetation, bare ground and litter in quadrats, as well as soil characteristics. Our results suggested that plant invasion reduced overall and flowering plant richness and positively affected the height of native vegetation. However, this did not affect ground-nesting bees’ abundance or species richness. Although we found invaded plots to have altered soil chemical characteristics compared to control plots, there was no correlation between soil characteristics and ground-nesting bees. The large explanatory potential of the random factors suggests that there were large differences in the abundance and species richness of ground-nesting bee species among the different habitat types and before and during the flowering of the invasive species. Although our study lacked a direct sampling of nesting bees, our results show the adverse effects of plant invasion on foraging and some nesting characteristics of ground-nesting bees. Future studies should put effort into the investigation of the number of nest holes and additional soil characteristics to get a better picture of the effects of plant invasion on ground-nesting activity.
