Abstract
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.
Highlights
Flora of water bodies is a set of species of aquatic plants and plants entering the water, found in a water body or in water bodies of a territory [1]
In 1995–2015, we studied the flora of water bodies and watercourses in six cities of Udmurt Republic (Izhevsk, Glazov, Votkinsk, Sarapul, Mozhga, Kambarka) located within the Vyatka-Kama Cis-Urals (VKCU)
This indicator is higher than the number of macrophyte species in the cities of the VKCU studied by us earlier, while the ratio of ecological groups is the same as in the cities of the VKCU
Summary
Flora of water bodies (watercourses) is a set of species of aquatic plants and plants entering the water, found in a water body (watercourse) or in water bodies (watercourses) of a territory [1]. The object of research is macrophytes – large plants visible to the naked eye, regardless of their taxonomic position and ecological confinement (higher plants and large multicellular algae) [1]. The flora of water bodies and watercourses is composed of aquatic macrophytes. In 1995–2015, we studied the flora of water bodies and watercourses in six cities of Udmurt Republic (Izhevsk, Glazov, Votkinsk, Sarapul, Mozhga, Kambarka) located within the Vyatka-Kama Cis-Urals (VKCU). It is of interest to what extent this pattern manifests itself in other regions that are close in physical and geographical conditions
