Prokaryotic diversity

The word ‘diversity’ may allude to the number of taxa or species richness as well as their relative abundance. There is uncertainty about both primarily because sample sizes are too short. Non-parametric diversity estimators make gross underestimates if used with small sample sizes on unevenly distributed communities. One can make richness estimates over several scales using small samples through assuming a species or taxa-abundance distribution. Through, no one knows what the underlying taxa-abundance distributions are for bacterial communities.
