Agricultural domestication of soils, that is, the conversion of previously uncultivated soils to a cultivated state, is frequently accompanied by intensive monoculture, especially in the developing world. Heat map generation showing likelihood of recurrence or remission The two-sided Student’s t-test was used to compare sets. The biplot position was calculated by the weighted average of the coordinate position of all genomes in the PCoA, where the weight was the abundance of the ARG-VF type in every genome and was plotted in a dimensional space using the ggplot2 package in R. Thereafter, the monoMDS() engine function is called repeatedly (up to trymax=20 times), each time with a new completely random starting configuration. Diet and host phylogeny drive the taxonomic and functional contents of the gut microbiome in mammals, yet it is unknown whether these patterns hold across all vertebrate lineages.
