Figure 2: Virodiversity of rhesus macaques in Bangladesh.

(a) Diversity of viruses discovered by family. (b) Maximum likelihood phylogeny of picobirnavirus diversity. Although viruses from many families were discovered, we have selected to show the PbV tree because of the substantial diversity observed. One section of the tree is shown as an insert for better visualization. (c) Viral discovery curve to assess saturation and estimate the total richnesss (number of viruses) that exists. Red line is the collector curve. Solid black line is the rarefaction curve. Dotted line indicates Chao2 estimation of asymptotic richness by sample number, and shading indicates 95% confidence intervals. (d) Rank abundance curve of the 184 viruses detected in this study.
