A rare species of Golden algae Chrysosphaerella coronacircumspina var. grandibasa was first discovered in the South Urals. The habitat of this rare species is high-altitude reservoirs with high water quality. Reservoirs located in the protected area of the «Taganay» national Park. C. coronacircumspina var. grandibasa vegetated during the subglacial period and after ice melting under conditions of oligotrophy, low specific electrical conductivity of water, low content of humic substances and neutral active reaction рН. The established conservation status of «Vulnerable species» VU(3) has been confirmed for the South Ural population of the rare chrysosphaerella. Low level of mineralization, oligotrophic water level, low temperature, and high water transparency have been confirmed as limiting factors for the development of South Ural populations of rare algae Chrysosphaerella. The results obtained Supplement information about the flora of Golden algae in Russia, the Urals, the southern Urals, and the «Taganay» national Park and can be used in environmental monitoring.
Ecological-phytocenotic assessment of the population status of the rare species Dictamnus gymnostylis Stev. (Rutaceae, Magnoliopsida) in the Southern Urals.
