Gaillardia aristata (great blanketflower) is planted worldwide and its escape has been reported in several European countries without ecological impact assessment on the invasive potential. As there is a markedly spreading population with invasive behaviour in Hungary, we aimed to reveal the distribution, impacts and traits of G. aristata . We gathered occurrence data outside the gardens in Hungary, based on literature, unpublished observations by experts and our own records. We investigated the impacts of an extended population, where the species invaded sandy old-fields within a 25 km 2 area. Here, we compared the species richness, diversity, community composition and height of invaded and uninvaded vegetation. Furthermore, we evaluated the traits potentially associated with the invasiveness of G. aristata in comparison with other herbaceous invasive species in the region. We found that G. aristata occurred mostly by casual escapes, but naturalised and invasive populations were also detected in considerable numbers. G. aristata usually appeared close to gardens and ruderal habitats, but also in semi-natural and natural grasslands and tended to spread better in sandy soils. We found lower plant species richness and Shannon diversity in the invaded sites and the invasion of G. aristata significantly influenced the composition of the plant community. The trait analyses revealed that the invasive potential of G. aristata is backed by a wide germination niche breadth, extremely long flowering period, small shoot-root ratio (large absorption and gripping surface), large seeds (longer persistence) and dispersal by epizoochory of grazing livestock (mostly by sheep), probably helping the species’ survival and spreading in the disturbed, species-poor, sandy, open habitats. These functional traits, as well as the ornamental utilisation, may act together with the aridisation of the climate and the changing land-use practices (e.g. abandoned, disturbed sites) in the success of G. aristata . We raise awareness of the rapid transition of G. aristata from ornamental plant to casual alien and then to invasive species in certain environmental conditions (i.e. sandy soils, species-poor communities, human disturbances), although it seems to be not a strong ecosystem transformer so far. Nonetheless, banning it from seed mixtures, developing eradication strategy and long-term monitoring of this species would be important to halt its spreading in time.

The general shape (from linear to complex curve), direction (negative, positive), and strength (steepness of the slope) of abundance-impact relationships for different impact metrics are poorly known, despite their importance in understanding and predicting ecological repercussions of invasive species. It is also an open question how the functional traits of invasive species may influence the abundance-impact relationship. 2. We studied 11 widespread herbaceous invasive alien species of East-Central Europe and their 16 impact metrics (resident plant communities’ ecological characteristics, trait composition, functional diversity, and soil parameters) by sampling invaded and similar, uninvaded sites (space-for-time substitution method). Our aim was to (1) investigate the detailed ecological impacts of invasive plants on native plant communities; (2) explore the type of cover-impact relationships across impact metrics and their consistency across species; (3) study whether the cover-impact relationship depends on functional traits of invasive species. 3. When considering all invasive species together, we found that invaded plant communities were less species-rich and less functionally even but showed higher values of Rao’s Q diversity index, and higher nitrogen, phosphorus, and organic carbon soil nutrient content compared to uninvaded communities. However, the species-wise analyses revealed strikingly different impacts among the 11 invasive species and also among impact metrics. 4. Regarding the type of cover-impact relationships, we found no consistencies across invasive species and impact metrics. Still, non-linear relationships prevailed when species were analysed together and linear relationships when species were studied individually. The functional traits of the invasive species explained only a small part of this response heterogeneity; mostly the small-seeded perennial invasive species affected the cover-species richness relationship. Synthesis: Herbaceous invasive plant species have a cover-dependent impact on resident plant communities, but there are no consistent patterns across impact metrics and invasive species. Specific traits or trait-syndrome of invasive species may affect the heterogeneity of cover-impact relationships, but that would need further study. We highlighted the importance of impact assessments involving invasive species’ abundance to unmask cryptic impacts for species that show contrasting effects along an abundance gradient.

However, their ecological effects on pollinators are complex: some species provide abundant floral resources, boosting the number of pollinators, while they often disrupt plant-pollinator interactions by outcompeting native plants. Our direct knowledge is mainly based on single-species studies, while understanding the mechanism of these complex ecological interactions needs multi-species field-based approaches. It is also imperative to clarify the pros and cons of invasive plants and drivers of invasion from the perspective of pollinators. We conducted a standard protocol-driven regional study in Central and Eastern Europe, comparing 6-7 invaded and non-invaded sites of 12 herbaceous invasive plant species. We sampled floral resources, bees, and hoverflies before and during the flowering of the invasive plants. We analysed the effects of plant invasion at the invasive plant species level and in combined analyses, and tested whether the life span (perennial vs. annual) and flowering time (early-, middle-, and late-flowering) of invasive plants affect the abundance, species richness, diversity and species composition of native plants and pollinators. The combined analyses showed lower abundance and species richness of flowering plants and pollinators before, and higher abundance of both during the flowering of invasive plants in invaded sites. However, invasive plants had significant species-specific effects. Perennial invasive plants had a stronger negative impact on floral resources and pollinators already before their flowering compared to annuals. Flowering time of invasive plants affected the pollinator guilds differently. We suggest that in certain critical time periods of the year, invasive plants might provide the dominant foraging resources for pollinators in an invaded ecosystem. But, they also often cause significant losses in native floral resources over the year. Instead of simple eradication, careful preparation and consideration might be needed during removal of invasive plants.

Therefore, seeds are under strong selective pressure to sense and integrate information about their environment and modulate germination based on it. In this study, we focus on interspecific seed-seed interactions under optimal and suboptimal conditions to test three hypotheses: (H1) dominant species' seeds and emerging seedlings are most likely to be recognised by neighbouring seeds and exert a significant effect on the germination of common subordinate species; (H2) taxonomically related species are expected to exert stronger influence than unrelated species on the germination of neighbouring seeds; and (H3) facilitative interactions are more likely to occur under suboptimal conditions (drought stress) in the seed-seed interactions.Location Semi-dry temperate grassland belonging to the Festuco-Brometea class, Cluj-Napoca, Romania.Methods We assessed the rate and speed of germination of three common subordinate Asteraceae species (target species) in a controlled germination experiment. The target species' seeds were sown in combination with low and high densities of neighbour species: two dominant Poaceae species, two subordinate Asteraceae species and two subordinate Apiaceae species; under optimal or drought conditions.Results Under optimal water conditions, particularly the seeds of the two dominant Poaceae species affected the germination of target species. Under drought stress, almost all neighbouring species altered the germination of two of the target species, enhancing or reducing their germination rate. Facilitation in seed-seed interactions was proved to be species-specific rather than general under drought conditions.Conclusions We found evidence that the status in a plant community (dominant or subordinate), but not the taxonomic relatedness influences the outcome of seed-seed interactions during germination. Under drought stress, the persistent competitive effect of the dominant species might considerably hinder the recruitment of subordinate grassland species.

The invasive common ragweed, Ambrosia artemisiifolia, has severe adverse effects on agriculture and human health, due to its vast production of seeds and allergenic pollen. Here, we identify the scale and nature of environmental factors driving individual performance of A. artemisiifolia, and assess their relative importance. We studied 39 populations across the European continent, covering different climatic and habitat conditions. We found that plant size is the most important determinant in variation of per-capita seed and pollen production. Using plant volume as a measure of individual performance, we found that the local environment (i.e. the site) is far more influential for plant volume (explaining 25% of all spatial variation) than geographic position (regional level; 8%) or the neighbouring vegetation (at the plot level; 4%). An overall model including environmental factors at all scales performed better (27%), including the weather (bigger plants in warm and wet conditions), soil type (smaller plants on soils with more sand), and highlighting the negative effects of altitude, neighbouring vegetation and bare soil. Pollen and seed densities varied more than 200-fold between sites, with highest estimates in Croatia, Romania and Hungary. Pollen densities were highest on arable fields, while highest seed densities were found along infrastructure, both significantly higher than on ruderal sites. We discuss implications of these findings for the spatial scale of management interventions against A. artemisiifolia. LA - English DB - MTMT ER -
