Protected Areas are considered as one of the most appropriate tool for biodiversity conservation. However, invasion of alien species is one of the main and widely known problems of these territories. Therefore, the timely detection and prevention of the invasive species dispersal is one of the main tasks of researchers in Protected Areas. The European species Hieracium sylvularum was found in the Mordovia State Nature Reserve in 2012. In the following years, new locations have been discovered there. That is why the main traits of the ecology and biology, invasiveness level of the alien species were studied. An investigation of the five known H. sylvularum locations has been carried out in the Mordovia Reserve. Attention has been paid to the age-structure of the populations, the accompanying floras' composition and morphometrical parameters of the generative individuals. The environmental conditions of habitats were revealed and compared using phytoindication methods. The mass and germination of seeds, harvested on different locations, were studied. The results indicate that H. sylvularum is not an invasive species. This alien plant is able to reproduce primarily vegetatively. Probably, the population area can extend gradually on each location. Seed dispersal is difficult due to low germinability of seeds, despite of their significant number per plant. Based on obtained results, dry and semi-dry light lichen-moss-Pinus-forests have a higher invasibility by H. sylvularum. Therefore, perhaps, its new locations may be found especially in these habitats. Annual monitoring of the currently known locations of this alien plant is necessary in the Mordovia State Nature Reserve.

“…This is supported by the relatively low value of population density (0.49-2.86 plants per 1 m 2 ). It is much lower than in well-established B. frondosa populations in the centre of European Russia (Republic of Mordovia) representing 77.7-198.0 plants per 1 m 2 and 36.3 plants per 1 m 2 for all and mature individuals respectively [9].…”

“…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.…”

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.

“…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.
