研究開始時の研究の概要 |
Elucidating the drivers behind the evolution of societies from solitary living organisms is one of the enduring questions in evolutionary biology. Recent studies have highlighted how the evolution of social immunity may be linked with the evolution of social systems, fuelled by the growing global interest in social immunity studies. Using a cutting-edge approach which combines transcriptomics and standard immune assays, we will be able to elucidate the relationship between immune efficacy, expression of social and individual immune traits, and social living.

研究実績の概要 |
The first experimental work on immune testing of Ceratina okinawana was completed. The development of a new immune testing method was successful and allowed us to provide new insights into the relationship between social evolution and immune system biology through our comparison of social and solitary nests. This work is currently in review in Biology Letters. The second round of experiments on gene expression in Lasioglossum was a success after shifting to liquid nitrogen preservation. In addition, student Ha Nguyen went to Princeton University in the US for the sequencing stage of the project and completed sequencing at the Lewis Sigler Institute for Genomics. These data are currently being analysed. We additionally continued work on Ceratina Okinawana with some early sampling at the start of 2023 which will continue throughout the year with new Masters student Manolo Benitez.

3: やや遅れている
理由
This study suffered delays in 2021 because of corona virus and loss of one set of samples because of an inappropriate preservation method. We repeated works in 2022 and this appears to have solved the issue so now data are available and are being analysed. Thus, while delayed slightly, we have managed to get things back on track and should be able to complete our aims during AY 2023.

今後の研究の推進方策 |
Work will continue as planned in 2023, though we will also continue to analyse the newly available RNAseq data somewhat later than expected. Plans for 2023 will center on using the Ceratina okinawana model system to explore spatial and social influences on immune responsiveness in this bee. We will be sampling throughout the year in Okinawa and performing comparative immune tests on bees sampled at TMU.
