Taylors power law (Taylor 1961,Nature,189:732-735) has been found to govern the population abundance distributions of single species in macro-ecology,and here we test its applicability to the bacterial species in the human vaginal microbiome (HVM).To do so we used vaginal bacterial community composition data derived from vaginal bacterial communities of 32 women between 22 and 53 years of age (Gajer et al.2012).
