Biodiversity Of Bryophyte Of Photic Zones Of Caves In The Kutuk Tract (Southern Ural, Bashkiria)

This article presents results of a study bryophytes in seven caves the Kutuk tract National Park «Bashkiria» Republic Bashkortostan, including largest cave Bashkiria – Kutuk-Sumgan.Fifty-five species were found studied caves. The dominant all was Timmia bavarica. composition each is unique. Among identified 23, only one cave, and 11 2 During our survey, we 31 Kutuk-Sumgan Cave, 21 Kutuk-2 Kutuk-3 caves, 19 Kutuk-4 18 Vintovaya Zigzag 14 Kutuk-1 cave. Using Jaccard Phi-squared similarity indices, revealed stability bryoflora different years show its changes. Changes structure mosses may be caused by mechanical influences. Benchmark analysis allowed us to determine influence entrance morphology glaciation photic zone on bryophytes.Using as an example, it shown that primary bryoflora, when selecting characteristic up 40% total can single current shows identification primere analyses bioflora permits individual cave.Three criteria for identified: size entrance, diversity habitats, least degree disturbance.
