| Outline of Final Research Achievements |
Phytopathogenic fungi and fungal like microbes occur frequently on moss and vascular plant species in polar regions. Characterization of the pathogens is important because they can affect the growth and community structure of many wild plants. In this study, I partially clarified the taxonomic and ecological features of the phytopathogenic fungi in Svalbard, a High Arctic archipelago. Fungi found in Svalbard, such as the ascomycete Rhytisma and the oomycete Pythium were discussed on their taxonomic positions and infection behavior. Present study described Rhytisma polare and Pythium polare as new species. They were consistently present in the living of polar willow (Salix polaris) and Sanionia moss (Sanionia uncinata) and were causing damages on their host plants. Moreover, their distribution patterns in the moss were affected by climatic factors.
