I would like to interpret the molecular diversity using the parameter nucleotide diversity (pi). The lowest value of Pi that I have is 0.00099 and the highest one is 0.02292. However, I have no reference to interpret these values whether it was considered as low, moderate, or high diversity? Do you know how to interpret these values?
It surely depends on what type and range of organisms you are studying. The diversity we observe in HIV-1 in one single infected individual over ten years is greater than the diversity we observe between different species of insects or mammals over millions of years. The diversity between viruses today in the global SARS-CoV-2 pandemic varies with time, depending on whether two major lineages such as Delta and Omicron are co-circulating or Omicron has taken over and delta died out.
The diversity in insect or birds or shellfish is different than the diversity in mammals. You should compare the values you have in your organism to the values from other similar organisms.
