Figure 2From: Phylogenetic representativeness: a new method for evaluating taxon sampling in evolutionary studiesFunnel plots of VarTD from four published data sets. Funnel plots of Variation in Taxonomic Distinctness (VarTD) from (a) bivalves [19], (b) carnivores [20], (c) coleoids [21], and (d) termites [22] data sets are shown. Results are from 100 random replicates. Thick lines are the upper 95% confidence limit and the lowest values found across all replicates of each dimension; the thin line is the mean across all replicates; experimental samples are shown by black dots. The bias towards lower values for small sample is detectable in mean.Back to article page
