Microbiome composition profiles generated from 16S rRNA sequencing have been extensively studied for their usefulness in phenotype trait prediction, including for complex diseases such as diabetes and obesity. One reason to explain the differences between the two univariate methods might be that DESeq2 does not adequately model sparse counts. I'm quite confused about using DESeq2 to find the differential abundant taxa in microbiome studies, especially when there are more than two groups of the factor. Motivated by this concept, we hypothesized that thermal acclimation in poikilothermic organisms, owing to their inability to maintain their body temperature, is connected to their microbiome composition.
