| Outline of Annual Research Achievements |
1. We did sampling for Oikolpleura dioica around Okinawa mainlads and Amami islands in July 2023. Besides O. dioica, we got other interesting marine zooplanktons. We have sequenced more than 107 O. dioica individuals sampled around Ryukyu islands in this project. We have finished the data analysis for these 107 indiviudals and found O. dioica around Ryukyu has very high genetic diversity and high proportion of rare variants. Genetic differentiation among these field sampling locations is very small.
2. I made a conference presentation titled Population Genomic Study Reveals Local Adaption Signal of Oikopleura dioica around Ryukyu islands in the International Symposium: Past, Present, and Future of the Marine Environment and Ecosystem, Tohoku, Japan.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We succeeded in sampling O. dioica around Ryukyu islands and have already sequenced 107 individuals with Illumina platform. And we are doing analysis and paper writing. We are going to submit the original research paper within this year, 2024.
|
| Strategy for Future Research Activity |
In this year, we are going to extend our sampling for better understanding the genetic diversity of this marine zoomplankton. And we are going to finish the data analysis of the previous 107 individuals and publish the results of this part.
