These unpublished analyses partly expand upon those in the ForamNiches project (https://github.com/GawainAntell/ForamNiches, published in PNAS 2021) and make up the final data chapter of my doctoral dissertation. The thesis is available open access at the Oxford Research Archive: https://ora.ox.ac.uk/objects/uuid:80ddc218-cb58-4599-b6be-c54e0b42cfe4. Check out Chapter 4 for a self-sufficient discussion of this project's aims, methods, and results.
