Description
Summary:Authors in 2015–2016 performed floristic and geobotanical researches in the southern part of the Tazovsky district (Yamalo-Nenets autonomous okrug), on the transect from the border with the northern taiga to the subzone of the southern shrub tundra, between 6623 and 6730 N. 263 species of vascular plants were noted, incl. 44 adventive species. In the taxonomic spectrum is dominated by Cyperaceae, Poaceae (28 species) and Asteraceae (26 species). Floristic diversity in transect sites ranges from 34 to 133 species, does not depend on geographical latitude and is determined by the position in the relief and the prevailing type of landscapes. Geographically, the flora has a boreal character, with a significant proportion of hypoarctic species. The new location of the protected species Subularia aquatica is revealed. Исследования выполнены в рамках программы научных исследований сектора биоразнообразия и динамики природных комплексов Института проблем освления Севера: базовый проект № 0372–2016–0004 «Оценка пространственно-временной изменчивости биоразнообразия и условий его формирования на Севере Западной Сибири в связи с изменением климата и освоением нефтегазовых ресурсов».
