Figure 2.

Results from unbiased cluster analysis. 125 spectra from flies of 13 different species were clustered using Dice coefficients. A color (heatmap) representation of the pairwise similarity (Dice) coefficients is shown in the lower part of the figure, the white square outlining the cluster of D. mauritiana spectra. Above this, clustering of individual spectra, color-coded according to species, are shown in a dendrogram. Percentages of bootstrapping replicates supporting the location of individual nodes are indicated. On top of this, a second dendrogram indicating the phylogeny of the different species is shown.
