摘要

2020年，在库尔干地区对西西伯利亚西南部河流植被的研究中，首次发现了一年生杂草Bidens frondosa L.(菊科)。该入侵物种在库尔干地区伊塞特河沿岸的10个地点被发现。我们假设斯维尔德洛夫斯克地区是沿伊塞特河入侵库尔干地区的灰树花杆菌的来源。尽管进行了一次短期的野外调查，但在几个地点发现了灰树花。在库尔干地区各样地均表现出低种群密度的特点。由于灰桫椤种群在俄罗斯欧洲其他地区的密度要高得多，因此预计未来库尔干地区的种群数量和密度将有所增加。

BIDENS FRONDOSA (ASTERACEAE), A NEW ALIEN INVASIVE PLANT SPECIES IN THE KURGAN REGION (RUSSIA)

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.

期刊介绍： Contributii Botanice is an international, peer-reviewed journal publishing scientifically sound papers in the fields of Plant Systematics, Phytosociology, Plant Physiology and Morphology, Plant Ecology, Population Ecology, Ecosystem Ecology, Phytogeography, Phytopathology, Microbiology, Paleobotany, Plant Conservation and Cell/Molecular Plant Biology. Papers of mostly taxonomic nature or focussed on floristics and phytosociology will only be considered if they exceed the pure descriptive approach and have relevance interpreting patterns in the above mentioned plant sciences.
