Phytodiversity of the Middle Volga region using FD SUR database

The article illustrates FD SUR database, which contains information on the spatial distribution of vascular plant species in Samara and Ulyanovsk regions. The surveyed area is 90,900 km2. The initial data were obtained as a result of studies carried out for the period 2004-2020 by the staff of the Institute of Ecology of the Volga River Basin of the Russian Academy of Sciences and some literary sources. The database contains over 100,000 records for 1935 species from 127 families and 628 genera. We develop a number of areas of flora research using the informational basis of FD SUR. We propose criteria for assessing the sustainability (natural addition) of floras based on the spectrum of family diversity indices. We studied the dependence of the taxonomic parameters of the flora on the number of species on floristic site and determined the values of these parameters for a number of territories of Samara-Ulyanovsk Volga region. We examined the dependence of the species and biomorphological composition of floras on the climatic conditions of the territory: the amount of precipitation and temperatures.
