a N refers to the total numbers of samples (replicates) collected at the time point over a 3-day period. Three samplings each were performed in triplicate at 1 am, 1 pm, and 7 pm, and four samplings were performed at 7 am. Samples that could not be rarefied to 22,380 sequences were removed from the dataset
bTimes sharing the same superscript did not differ significantly by post hoc test for a given host environment (P > 0.05)
