Differential abundance testing with ANCOM confusion

In the “Moving Pictures” tutorial, ANCOM analysis has two results[“Moving Pictures” tutorial — QIIME 2 2020.8.0 documentation].But, they are different.

In my mind, the taxonomy name of result2 points to the ASV id of result1.
I am confused

The ASV and Taxa results are not necessarily the same, since several ASVs, assigned to the same taxa, could demonstrate completely different behaviors and abundances.


thanks for your reply.
SO, which result is used more frequently or reasonable?

It depends on your experiment design, but actually you can use both results.
I prefer ASVs results since they provide a higher resolution for your analysis, but it is not a mistake describe both results on different levels in your report/paper.
