The main factors ant-fungus pairing (nominal) and time (nominal) are included, in addition to the interaction between ant-fungus pair and time. Due to missing data as sub-colonies started to crash, the ANOVAs evaluating actinobacterium abundances could not be done over the entire duration of the experiment. Thus, for pairings A on fungus from colony A, K or D, C on fungus from colony C, J, or D, D on fungus from colony D, E, or J, and H on fungus from colony H, I, or K only days 11–23 were included. For the remaining pairings (C on fungus from colony C, I, or D; A on fungus from colony A, I, or D; and F on fungus from colony F, I, or D), tests were performed only on data from days 11–21.
