Models, diversification rates

The LTT plot (Figure 17.2) allows comparison of the pattern of diversification of extant taxa in the pleurocarpous mosses with the equivalent curves for the angiosperms and polypod ferns as calculated by Schneider et al. (2004). Note that the shape of these plots is susceptible to differences in the sampling strategy (Nee et al., 1994 Pybus and Harvey, 2(XX) Shaw et al., 2003). Issues of systematic sampling bias were not explored by Shaw et al. (2003), who concentrated instead on the effect of randomized incomplete sampling, allowing them to accept or reject different models of diversification rates.
