... Now that we have empirically obtained limits for all EFVs in the Tsyganov [3] environmental scales, this allows researchers to use these data to calculate mean EFVs for floristic lists of plant communities where Bidens frondosa occurs. This is especially relevant because, at present, there are now plant communities of low species diversity dominated by B. frondosa in various parts of the invaded range, e.g., [24,25]. Besides B. frondosa, many other widespread invasive species (e.g., Echinocystis lobata, Ambrosia trifida) are absent in the Tsyganov [3] scales, which highlights a need to perform similar studies to establish EFVs for these alien plants required for phytoindication analysis. ...
To identify habitat conditions, indirect ordination methods on the basis of environmental scales are used widely in Europe. However, many alien plants are absent from those scales. Bidens frondosa (Asteraceae) is an invasive alien species distributed widely in Europe. It is becoming a significant part of natural plant communities, sometimes forming monospecific stands. This study aimed to empirically determine environmental factor values using analysis of the flora accompanying B. frondosa in 22 regions of European Russia collected in a 34-year time span. In European Russia, Tsyganov environmental scales are widely used for such analyses. We determined intervals of values for each environmental factor according to Tsyganov environmental scales, namely thermoclimatic scale (TM: 7.3–9.4), climate continentality (KN: 6.0–9.4), climate aridity/humidity (OM: 6.1–8.6), cryoclimatic scale (CR: 5.3–8.8), soil moisture (HD: 9.9–17.6), scale of the soil salt regimen (TR: 5.1–10.7), soil nitrogen availability (NT: 4.4–8.5), soil pH (RC: 4.8–8.8), habitat shading (LC: 2.0–4.5), and soil-moisture variability (FH: 0.7–5.9). These data on environmental factor values can be further used in ordination analyses of plant communities where B. frondosa appears in the subzone of coniferous-deciduous forests of Eastern Europe. Results of this study demonstrate the ecological preferences of this species and can be used to determine conditions of habitats invaded by B. frondosa.
... In our data set, 8 species were found at elevations above 500 m. The two most common were Bidens frondosa and Phytolacca americana; both native to North America and invasive in many temperate regions of the world (Huang and Ding, 2015;Ronzhina, 2017). ...
The number of alien plant species is growing steadily across all world regions. These numbers tend to be exceptionally high in riparian ecosystems, often with substantial negative consequences for native species communities and ecosystem services provision. Here, we map the richness of invasive alien plant species in riparian ecosystems of continental Portugal, assess the relative importance of human and natural factors in shaping the uncovered patterns, and predict richness values along watercourses and at the municipal level for the whole study area. We found a higher richness of invasive alien plants in low altitudes and in downstream areas where human concentration is high. As time progresses, ongoing and increasing levels of socio-economic activity and globalization of plant trade will conceivably lead to a higher number of alien species becoming established. National and sub-national measures aiming to prevent and manage biological invasions in riparian ecosystems require coordinated efforts involving both local entities and those with responsibilities in the management of upstream catchment areas. These efforts must also be targeted to achieve future biodiversity protection goals as part of the EU Biodiversity Strategy for 2030.
... However, Solanum rostratum and Erigeron canadensis usually invade nutrient-limited habitats such as sandy soil, having low nutrient requirements (Đurđević et al., 2015;Juan et al., 2013;Thébaud et al., 1996;Zhang et al., 2017;Zhao et al., 2013). Bidens frondosa, Xanthium strumarium, and Ambrosia trifida generally invade nutrient-rich habitats with regular nutrient addition, such as farmlands and wetlands, having high nutrient requirements (Danuso et al., 2012;Dong et al., 2020;Follak et al., 2013;Iqbal et al., 2020;Ronzhina, 2017). The native species Bidens tripartita and Solanum nigrum are often found in fertile habitats (Jagatheeswari et al., 2013;Särkinen et al., 2018) with high Ellenberg's nitrogen indicators (Hill et al., 1999), exhibiting high nutrient requirements. ...
High phenotypic plasticity has long been considered as a characteristic promoting exotic plant invasions. However, the results of the studies testing this hypothesis are still inconsistent. Overlooking the effects of species resource requirements and environmental resource availability may be the main reasons for the ambiguous conclusions. Here, we compared phenotypic plasticity between five noxious invasive species with different nutrient requirements (evaluated using the soil nutrient status of their natural distribution ranges) and their phylogenetically‐related natives under five nutrient levels. We found that species with high nutrient requirements showed greater plasticity of total biomass than species with low nutrient requirements, regardless of their status (invasive or native). Invasives with high nutrient requirements had greater growth plasticity than their related natives, which may contribute to their invasiveness under high‐nutrient environments. However, compared to the related natives, a higher growth plasticity may not help exotic species with low nutrient requirements to invade nutrient‐rich habitats, and exotic species with high nutrient requirements to invade nutrient‐limited habitats. In contrast, invasives with low nutrient requirements exhibited lower growth plasticity than their related natives, contributing to their invasiveness under nutrient‐limited habitats. Functional traits showed growth‐related plasticity in only 10 cases (3.8%), and there was no functional trait whose plastic response to soil nutrients was beneficial to exotic plant invasions. Our study indicates that low growth plasticity could also promote exotic plant invasions, high plasticity may not necessarily lead to invasiveness. We must test the adaptive significance of plasticity of functional traits when studying its biological roles.
... The relationships of the alien B. frondosa with its native congeners (e.g., B. tripartita, B. radiata, B. pilosa), as well as with its environment, have been intensively studied in Eurasia. It has been shown that B. frondosa has higher seed mass and productivity, as well as dry mass and growth rates as compared to B. tripartita, and B. radiata in European Russia [9,18,19] and Western Europe [5]. Various authors have demonstrated the higher resistance of B. frondosa to heavy metals [13], as well as larger morphological variability under influence of environmental factors [17,22] in comparison to native Bidens congeners in the ecosystems of Eurasia. ...
... Therefore, research on alien plant diversity is relevant in many regions. In 2015, Ronzhina [18] demonstrated the high invasive activity of B. frondosa in the Sverdlovsk Region. However, in the adjacent Kurgan Region, this invasive species had not been recorded [16]. ...
The annual weed Bidens frondosa L. (Asteraceae) has been registered for the first time in the Kurgan Region in 2020 during research on the riverine vegetation of the southwestern part of Western Siberia. This invasive species was found in ten locations along the Iset River banks in the Kurgan Region. We have postulated that the Sverdlovsk Region serves as a source for the B. frondosa invasion into the Kurgan Region along the River Iset. Despite a single short-term field survey, B. frondosa was found in several sites. In the Kurgan Region, this invasive species is characterized by low population density in all plots. Since B. frondosa populations are characterized by much higher density in other regions of European Russia, an increase in the number of locations and density of populations is expected in the Kurgan Region in the future.
... This species has also spread widely along rivers and streams in Bashkortostan Republic (Russia), where its presence causes even osier-beds to dry out [52]. The spread of B. frondosa along rivers is confirmed by other studies: in Poland along the Odra river from Germany, then along the Bug and Vistula river valleys [37]; in Russia, e.g., on the banks of the Rybinsk Reservoir located on the Upper Volga river [53]; in disturbed riverside habitats in the upper stream of the Iset' river [54]; and in the Bashkortostan Republic [52]. Similarly, the spread of X. albinum is mainly related to human-disturbed habitats: along two large rivers (the Vistula and the Bug) in Poland [37]; along the Elbe river in Germany [55]; and in the flood plains of rivers, in moist riverbed habitats and coastal sands in Russia (Bashkortostan Republic) [52]. ...
Invasive alien species (IAS) is a global problem that largely relates to human activities
and human settlements. To prevent the further spread of IAS, we first need to know their patternof distribution, to determine which constitutes the greatest threat, and understand which habitats and migration pathways they prefer. Our research aimed to identify the main vectors and distribution pattern of IAS of plants in the city environment. We checked the relations between species distribution and such environmental factors as urban soil type and habitat type. We applied data on IAS occurrence (collected in the period 1973–2015) in 515 permanent plots with dimensions of 0.5 x 0.5 km and analyzed by direct ordination methods. In total, we recorded 66 IAS. We found a 27% variance in the IAS distribution pattern, which can be explained by statistically significant soil and habitat types. The most important for species distribution were: river and alluvial soils, forests and related rusty soils, and places of intensive human activities, including areas of urbisols and industriosols. Our results provide details that can inform local efforts for the management and control of invasive species, and they provide evidence of the different associations between natural patterns and human land use.

... With the same biomass of the 21-day-old seedlings, the almost two times larger leaf area of the invasive species caused larger LAR values, which is an important component of RGR based on the formula RGR = LAR × NAR (Lambers et al., 1998). Earlier, it was shown that investments in leaf area in the early stages of ontogenesis greatly increase the growth potential of herbaceous plants (Hunt and Cornelissen, 1997 (Ronzhina, 2006(Ronzhina, , 2017Pyšek and Richardson, 2007;Hovick et al., 2012). ...
We studied the relative growth rate of seedlings and aboveground and underground organs, as well as functional traits of leaves and absorbing roots in the invasive species Heracleum sosnowskyi and congeneric native species H. sibiricum. The plants were grown in laboratory conditions and the functional plant traits of 21- and 35-day-old seedlings were analyzed. The relative growth rate (RGR) of H. sosnowskyi differed from that of H. sibiricum by 2.5 times, but the growth of plants in height and in area of leaves was similar. Plant biomass and total leaf area were twice as high in 35-day-old seedlings of invasive species. Structural features of the leaves in 35-day-old H. sosnowskyi seedlings were a lower leaf thickness and a higher leaf density. The invasive species had a lower root mass ratio, but the roots were more branched with a greater ratio of absorbing roots and a better development of the root hairs. As a result, H. sosnowskyi had a higher growth rate of absorbing roots (by 2 times) and a larger absorbing surface in relation to the total root surface. We concluded that the structural and functional traits of the leaves and roots provided a 2 times higher net assimilation rate (NAR) and 2.5 times larger RGR in the invasive species H. sosnowskyi.
