Hello all,  
Let me first describe the background of my experiment.  
I study the microbiota in insects. One of my projects is to sequence the insect bacteria at different ages. The problem is everytime I have to sacrifice the insect to get the DNA for sequencing. I was wondering if I can use the longitudinal volatility function to trace the group change during the ages?

I found that there are a lot of different longitudinal functions available, do you have any recommended longitudinal function to analyze the microbiota change over time for those samples need to be sacrificed every sampling?

Thanks ahead!

I feel your pain. We had to use destructive sampling to get timeseries samples for [this project](https://academic.oup.com/femsec/article/93/10/fix121/4555378).

The argument we made to reviewer three was that

1. there's no better way to get this data 🤷
2. we carefully designed the lab experiment so that these samples could be considered biological replicates, even though they are physically different samples

We then treated the data as if it were from repeated-measures sampling. For this you could use [`longitudinal linear-mixed-effects`](https://docs.qiime2.org/2023.5/tutorials/longitudinal/#linear-mixed-effect-models) or  
[`longitudinal volatility`](https://docs.qiime2.org/2023.5/tutorials/longitudinal/#volatility-analysis).

Also consider `first-distances` with `--p-baseline`, which does not necessarily assume repeated-measures sampling at all!
