Additional file 6: Figure S5. Relative expression levels (log2 CPM) of 517 differentially expressed genes between sympatric and allopatric frogs. The dendrograms resulted from hierarchical clustering of expression levels after 100 replicates to estimate Approximately Unbiased p-values (numbers on nodes). Gene names are Uniprot identifiers and can be found in the reference transcriptome annotation file (see Availability of data and materials).
