Outline of Final Research Achievements

The goal of this　project　is　to　clarify　the　biogeography　and　biodiversity　of　micro-organisms,　phytoplankton　and zooplankton by meta-genomic　method　using　a　high　throughput　sequencer.　The　metagenomic　methods　have　established　for bacteria, archaea, diatoms, haptophytes and calanoid copepods, which were ten-times faster than classical method such as microscopic one without effects of individual's skills and experiences. Using these methods for samples collected from wide areas of the Pacific, we found that phytoplankton and zooplankton were distributed along with the surface current system. However, bacteria and archaea were more effected by their life styles (free-living and attached).
