| Research Abstract |
Based on core samples collected in Tsukumo Bay in the Noto Peninsula, Ishikawa Prefecture, the Larger foraminifera Amphistegina radiate have been present since the early 1900s. Amphistegina radiata generations from the Tsukumo Bay were determined based on their proloculus sizes. Absence of Schizont and Gamont generations may suggest abortive migration in the bay. In conclusion, the generations of Amphistegina radiata that occur in the Tsukumo Bay are likely Agamont and Schizont and although they reproduce, a trimorphic life cycle has not yet been completed.
