Abstract

Water bodies are characteristic elements of the modern landscape, including cities, where they, along with forest ecosystems, serve as environmental frameworks of territories. Monitoring of the plant diversity in urban water bodies enables early detection of changes in the structural and dynamic characteristics of the plant communities. We studied the flora of water bodies and watercourses in the city of Tobolsk (Tyumen Oblast) and published an inventory of the identified flora, which was later supplemented by several more taxa. The purpose of this work is to analyze the most important characteristics of the studied flora. The current study includes data on 280 species of macrophytes, united into 136 genera and 66 families. This paper reports data on the taxonomic composition and ecological, biomorphic, and geographical structure of the studied flora, including protected species (Acorus calamus, Caulinia minor, Zannichellia repens, Lycopodiella inundata, Epipactis palustris, Nuphar pumila, Nymphaea tetragona, and Saxifraga hirculus) and adventitious species (Elodea canadensis, Iris pseudacorus, Chenopodium glaucum, C. rubrum, Echinochloa crusgalli, Epilobium adenocaulon, E. pseudorubescens, Impatiens glandulifera, Phragmites altissimus, Typha laxmannii, and Ceratophyllum platyacanthum subsp. oryzetorum). The data obtained indicate that there are a number of factors that determine the taxonomic richness and ecological diversity of the hydrophilic component of urban floras. These include: 1) the presence and diversity of habitats of aquatic and semi-aquatic plants within the urban landscape; 2) the position of the city territory in the system of regional (zonal-meridional) land units within the physical-geographical country; 3) the age of the city. The composition of macrophytes is not affected by the area of the city and its geographical location within a limited region
