R alpha beta diversity
WebbBeta diversity is a term used to express the differences between samples or environments. It is very often used in microbiome studies to help researchers see whether there are major differences between two groups, such as treatment and control groups.

WebbI chose to calculate the diversity within samples using two different metrics; one phylogenetic metric (i.e. takes into account the relatedness of the bacteria) and one non-phylogenetic metric (doesn’t take this into account). I then compared the alpha diversity value between groups of samples. WebbOptions for alpha diversity are richness, shannon, simpson, gini.

Compare each measure of alpha diversity with the library size. What is problematic? (You can take inspiration in the code below on how to do this in R) WebbThis is not an R problem, but a question of the difference between alpha and gamma diversity in ecosystems and would be better served in r/evolution or a similar subreddit (a Google search might go a long way here)..
