Abstract: In 2020, the first record of Wolffia arrhizawas made in Novosibirsk region (Western Siberia) in a floodplain lake. Wolffia arrhizaformed vast stands with an area of hundreds of square meters and with high productivity. Besides monodominant communities, it was met as a component of the cenoses of such hydrophytes as Stratiotes aloidesand Hydrocharis morsus-ranae, as well as of the helophyte communities formed by Typha latifoliaand Eleocharis mamillata. According to local residents, Wolffiawas observed as abundant for some years; thus, most likely, the population winters safely at the latitude of Novosibirsk. The most likely source of Wolffia arrhizaappearance in the lake was an accidental introduction from an aquarium, although the possibility of this plant entering the lake in high-water years from the wastewater of the municipal settling tank of Novosibirsk sewage waters also exists. |
