| Popis: |
The flora of water bodies and watercourses of the city of Tobolsk is composed of 266 species of macrophytes, including both higher plants and macroalgae. This indicator is higher than the number of macrophyte species in the previously studied cities of the Vyatka-Kama Cis-Urals, while the ratio of ecological groups remains the same. The taxonomic richness and ecological diversity of the hydrophilic component of urban floras depends on a number of factors: 1) the presence and diversity within the urban landscape of habitats inhabited by aquatic and semi-aquatic plants; 2) the position of the city’s territory in the system of regional land subdivisions within the physical-geographical country; 3) the age of the city. The composition of macrophytes is not affected by the size of the urban area and the geographical position of the city within a region. |
