The importance of mycorrhizal fungi in primary succession
Nevěčná, Michaela ; Münzbergová, Zuzana (advisor) ; Püschel, David (referee)
Primary succession is a relatively long-term process of colonization of a certain area, which has never been influenced by any biotic environmental elements. There are many factors that influence primary succession. One of them are mycorrhizal fungi. Establishment of mycorrhizal symbiosis, i. e. a mutualistic relationship between plants and mycorrhizal fungi, can be an important factor facilitating development of vegetation cover. Plants profit from mycorrhizal symbiosis thanks to increased nutrient acquisition, protection against toxic heavy metals or an advantage in a competition with non-mycorrhizal plants. Being non-photosynthetic organisms, fungi gain assimilates from the plants. Modification of the course of primary succession by adding mycorrhizal fungi can have a big importance in reclamation of the areas damaged by mining and there is a potential to substitute, at least partly, technical reclamations.

The importance of mycorrhizal symbiosis for the course of primary succession in a limestone quarry
Nevěčná, Michaela ; Münzbergová, Zuzana (advisor) ; Gryndler, Milan (referee)
Arbuscular mycorrhizal symbiosis was established millions of years ago and became one of the most symbiotic relationship at all. With increasing human interventions in the natural environment, its importance is growing. Understanding the importance of mycorrhizal fungi in the succession of vegetation on spoil banks , can significantly help rebuild the disturbed sites and can significantly reduce the cost of the entire process of reclamation. The aim of this study was to describe the development of arbuscular mycorrhizal fungi on spoil bank of quarry Čeřinka and the ability of these fungi to influence the structure of local plant community. To fulfil these aims, mycorrhizal inoculum potential was determined. It demonstrated that mycorrhizal fungi spread on spoil bank relatively fast. Application of soil, a source of inoculum of arbuscular mycorrhizal fungi and other soil microorganisms did not influence the composition of the plant community. Greenhouse experiment with two of the original steppe plant species, describes the importance of arbuscular mycorrhizal fungi for spread more specialized species in the spoil bank. Key words: arbuscular mycorrhizal symbiosis, succession, dump, limestone quarry, vegetation
