Soil algae and cyanobacteria in the alpine plant communities,Soil algae and cyanobacteria are important components of most terrestrial ecosystems (Shtina & Gollerbakh 1976). As photosynthetic organisms, they take part in the primary production of the plant communities and are important food resources for the soil invertebrates. Cyanobacteria also play an important role in the nitrogen balance.

Fungi, mycorrhiza, and microbiological processes in the alpine ecosystems,Numerous studies on soil microfungi have been carried out since Adametz in 1886 first isolated fungi frrom a soil. Despite this fact, our knowledge on the soil fungi of many regions remains incomplete.
