Figure 2. Rarefaction curve for the species richness found in the pellets of the barn owl (mean and standard deviations) based on the number of replicates sampled. The asymptotic curve indicates that total species richness in the Tamarugal was reached after ca 63 samples. Calculation was performed using the EstimateS 7.5 program.
