| Outline of Research at the Start |
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.

| Outline of Annual Research Achievements |
Research demonstrating for the first time that group size is inversely proportional to individual immune efficacy in Ceratina bees was published in Biology Letters. Additional comparisons of immune efficacy over seasons and across environmental contexts (urban/rural) in these bees are currently being completed. Data collation on how gene expression varies during immune responses in social and solitary Lasioglossum bees has been completed and this work is being written up. The final aspect of the study concerns host-parasite relationships between bees and varroa mites and is also being written up. More immune testing on Ceratina stemming from this work will continue into 2024.
