THE MYCOBIOTA OAK FORESTS OF THE URAL RIVER VALLEY WITHIN THE WEST KAZAKHSTAN REGION

The study and conservation of biodiversity is one the global problems modern biology, since at present in many regions planet there a decrease species composition various organisms, including fungi. information obtained makes significant contribution to knowledge diversity macromycetes oak forests middle reaches Ural River, about which Kazakhstan still insufficient fragmented. article presents data on mycobiota Urals valley, growing not only floodplain river, but also beams, that is, ravine flowing into central floodplain. We have registered 31 belonging 23 genera, 17 families five orders. leading are Polyporaceae, Boletaceae, Russulaceae, Amanitaceae. As result our research, it has been found mycological richer than forests. richness appears influenced by well-defined associations (22 associations), represented forest boreal tree-shrub absent forests, as well favorable microclimatic conditions, relief, soil cover ecotopes observed (16 associations). Ecological-trophic analysis showed predominance mycorrhizal (45.1%) xylotrophs (41.9%) over humus saprotrophs (12.9%). considered taxonomic studied area collected, identified presented for first time this region. Key words: mycobiota, macromycetes, forest, biodiversity.
