Effects of Taxon Sampling in Reconstructions of Intron Evolution

Figure 3

Examples of sampling size-intron density correlation patterns inferred by the Csuros (left) and NYK (right) algorithms. Horizontal axis: number of species in the sampling. Vertical axis: inferred intron density at the node (introns/kb). Note that NYK returns estimations of ancestral intron count rounded down to integers, therefore bubble diagram was used. Bubble size represents number of data points at the same scatterplot coordinates.
