Outline of Final Research Achievements

Metagenome analysis on prokaryotes and eukaryotes was almost completed on moss pillars in Antarctic lakes. By understandings the biodiversity mainly on microbes, and reconstruction of material cycle by them, the meaning of moss pillars as a type- ecosystem for further studies was thought to be established. On mosses, diatoms and fungi, the diversity in wide area of Antarctica was clarified, and the studies on comparative analysis between the area and inter-specific relations were carried out. Especially on tardigrades, the diversity in Syowa Station area were completed and the researches on reproductive ecology by using culture system has developed and their characteristic features were clarified. On alien species, the origin of human-induced seed plant found in Langhovde area was clarified and risk on Antarctic biodiversity was estimated.
