    Влияние рекреационной нагрузки на формирование циано бактериально-водорослевых ценозов в условиях городской среды [Articol]
    (CEP USM, 2014) Суханова, Наталья
    Due to the increasing urbanization recreational impacts on natural systems is constantly grows. Trampling is primarily reflects on land cover. We studied soil cyanobacterial- algal cenoses with various rate of recreational load in settlements of South Ural forest- steppe zone. There was found 119 species of soil algae and cyanobacteria, including forms and variations. 37 % of them belonged to Cyanoprocariota, 38% – to Chlorophyta, 22% – to Ochrophyta (9% – Xanthophyceae, 12% – Bacillariophyceae, 1% – Eustigmatophyceae), 2% – to Streptophyta , 1% – to Euglenophyta. Biodiversity of edaphotrophs is presented with 5 division, 9 classes, 21 orders, 46 families, 67 genus. We identified a group of frequently occurring species, dominant and subdominant, identified leading families in terms of the number of species. It was found out that the spices diversity and abundance of soil phototrophs increase upon the low recreational influence, at the significant recreational influence – considerable decline.
