Figure 1 Fig. 1. Arcsine square root plot of mean {pi}S versus H for eight orders of eutherian mammals (numbers of species are given in parentheses). A nearly identical relationship exists for mean {pi}T versus H ({tau} = 0.84, P < 0.005). Furthermore, our results are robust in that P remains <0.005 when three pairs of orders with nearly identical {pi} or H diversities, i.e., Artiodactyla/Chiroptera, Carnivora/Insectivora, and Chiroptera/Primates are counted as ties in the Kendall tests. Individual {pi}S and {pi}T estimates for each species were based on the Nei-Gojobori method with a Jukes-Cantor correction and on the Kimura two-parameter distance with a gamma distribution ({alpha} = 0.5), respectively (7). Otherwise, our methods followed those of Bazin et al. (1). [View Larger Version of this Image (26K GIF file)]
