Figure 5. Histogram showing the frequency of 1000 randomly generated simulations, based on the actual matrix data for small mammals from savannah fragments of different sizes. In the simulations, groups of species were allowed to occur randomly in each fragment, generating a normal distribution. Notes: Arrow indicates the degree of nestedness observed for the actual data which was significanty higher than expected by chance (p = 0.023); NODF was the metric used for nestedness analysis (Guimarães and Guimarães 2006; Almeida-Neto et al. 2008).
