The diversity of genera has decreased in the majority of releases since November 2013. a The number of observed species has outpaced the number of observed genera, which has in turn outpaced the number of families as RefSeq has grown. b The ratio of strains-to-species has tended to decrease while the ratio of species-to-genera has tended to increase as RefSeq has grown. c Simpson’s diversity index of species in bacterial RefSeq has tended to increase every release (appearing to have plateaued recently), while Simpson’s diversity of genera tended to increase until November 2013, where it has tended to decrease
