“…Crowe and Parker (1981) considered B. connata a possible hybrid between B. frondosa and B. cernua; however, they did not find reliable evidence for this hypothesis. Few works about potential B. frondosa hybrids with other related species are reviewed in Vinogradova et al (2014). The most recent information on this topic is provided from studies in the upper basin of Volga on potential hybrids by V. G. Papchenkov and other Russian botanists, which were critically revised by Vinogradova et al 2014and Galkina et al (2015).…”

“…B. frondosa has a highly flexible vegetative phase and can grow taller and produce more seeds than its congener, B. tripartita (Danuso et al, 2012). In parts of Europe, B. frondosa has displaced the native B. tripartita and B. cernua in some habitats (Vinogradova et al, 2014). According to the literature, the impact of alien species on native plant communities and native congeners could be dual: ecological -out-competed native species, and geneticinterspecific hybridization between the invader and native species (Bleeker et al, 2007).…”

“…Interspecific hybridization is known to sometimes produce genotypes with increased weedy properties and invasiveness (Ellstrand, Schierenbeck, 2000). The genetic impact of B. frondosa on the native species is controversial because plants of intermediate morphology have been found in natural ecosystems; however, no proof of hybridization has been obtained for the studied genotypes (Crowe, Parker, 1981;Vinogradova et al, 2014;Galkina et al, 2015). The analysis of the genetic structure of invasive populations of B. frondosa has not received sufficient attention until now and is limited to a genetic diversity analysis of a small number of genotypes (Galkina et al, 2015).…”

River riparian ecosystems deteriorate because of anthropogenic factors that are related to industry, intensive agriculture and tourism. Two native species, Bidens tripartita and B. cernua, are weeds widespread in Lithuania on river banks and other habitats. An alien species, B. frondosa, is also widespread in the same habitats. We investigated the genetic diversity of B. frondosa, compared its population structure to that of related species and assessed the possibility of genetic interaction between B. frondosa and native congeners. Genetic analysis of populations was based on inter-simple sequence repeats (ISSR) polymorphism. Our results revealed high genetic differentiation in the B. frondosa populations (48.2%) and high genotypic diversity (i = 0.99). Bayesian cluster analysis using the program Structure revealed signs of gene flow between B. frondosa and the native species; however, principal coordinate analysis did not support this result. Our results do not indicate the role of interspecific hybridization in the invasiveness of B. frondosa.

“…Nowadays, the foreign species are actively introduced into natural ecosystems, occupying stable positions in the composition of the flora, driving local species from the plant communities due to their high competitive ability (Vinogradova et al, 2014;Galkina et al, 2015). An example of such species is Bidens frondosa L. (Devil's beggarticks)a North American invasive species of the Asteraceae family (Abramova & Nurmieva, 2013).…”

“…According to the data of the DAISIE programme, B. frondosa is listed as one of 50 commonest and most aggressive invasive species in Europe (Chytry et al, 2008;Vinogradova et al, 2010;Van Kleunen et al, 2015). Its biology and ecology in the conditions of its secondary range have been studied in a number of works (Brandel, 2004;Pyšek & Richardson, 2008;Borisova, 2010;Hovick et al, 2012;Kostrakiewicz-Gierałt & Zając, 2014;Vinogradova et al, 2014;Galkina et al, 2015;Khapugin et al, 2016;Yan, 2016). One of the approaches to the assessment of competitive ability of invasive species is a comparative analysis of morphological, physiological and reproductive features of these species with native species of the same genus (Pyšek & Richardson, 2012).…”

Resistance of seedlings of native and alien species of the genus Bidens (Asteraceae) from different geographic populations to the action of heavy metals

One approach to assessing the competitiveness of invasive species is a comparative analysis of the morphological, physiological, and reproductive traits of this species with native species of the same genus. The invasive species Bidens frondosa L. from the Asteraceae family, included in the list of the 50 most common and most aggressive invasive species in Europe, occupies the same ecological niche as the native species B. tripartita L., and displaces it from natural habitats. There is an obvious and growing interest in the sustainability of B. tripartita and B. frondosa in extreme conditions of existence, one of which is the action of heavy metals. Our research was performed in laboratory conditions with seedlings that developed from seeds collected from populations of the Upper and Middle Volga region. The seeds were germinated in Ni2+ and Cu2+ solutions at various concentrations. At the end of the experiment, morphometric parameters were measured and the index of tolerance was determined. Seedlings from different populations under the influence of nickel ions developed at concentrations of 1–50 mg/l, under the influence of copper ions – at 1–100 mg/l. The nickel and copper ions had the greatest toxic effect on the growth and development of the root system – at 25 mg/l and above, the main root was completely necrotic, while the action of copper ions simultaneously increased the number of adventitious roots. The tolerance index (“root test”) under the action of nickel ions was higher among the seedlings from the population of the Middle Volga region, while under the action of copper ions there were no significant differences among the seedlings from different populations. However, it decreased with the action of both heavy metals at a concentration of 10 mg/l. High concentrations of both metals significantly reduced the length of the hypocotyl, cotyledon, and the true leaf. It was also found that copper ions are more toxic for the root system (main root and adventitious roots), nickel ions – for above-ground organs (hypocotyl, cotyledons, and true leaves). We noted differences between the populations to the action of nickel and copper. From the population of the Upper Volga region, the seedlings of B. frondosa were more stable. For seedlings from the population of the Middle Volga, a smaller toxic effect was confirmed for B. tripartita. It can be assumed that the resistance of B. frondosa to the action of heavy metals as a stress factor in the Upper Volga region is one of the reasons for the suppression of B. tripartita by the invasive species.
