Floristic diversity of the Lower Ob River floodplain in the Yamalo-Nenets Autonomous Okrug
Information on the flora of the Lower Ob River floodplain being about 500 km long within the Yamalo-Nenets Autonomous Okrug (YNAO) has been summarized for the first time. The taxonomic diversity of the floodplain flora is considered in the latitudinal aspect. The total number of taxa is 322 includin...
