Figure 2 in Molecular systematics of the Philippine forest skinks (Squamata: Scincidae: Sphenomorphus): testing morphological hypotheses of interspecific relationships
Figure 2. Molecular phylogeny, morphological unweighted pair group method with arithmetic mean (UPGMA) clustering, and principal components analysis (PCA) plot for Philippine Sphenomorphus. The molecular phylogeny is the Bayesian maximum consensus tree from the combined 17-partition analysis. Posterior probability values equal or greater than 0.95 are black circles, above 0.75 are white circles, and below 0.75 are not shown. Morphological UPGMA clustering was calculated in JMP using average distances. The PCA plot is for PC1 and PC2 in Table 7. Species groups from Brown & Alcala (1980) are colour-coded. Morphological UPGMA clustering shows species groups are morphologically congruent, but the phylogeny demonstrates that the same morphological types are convergent.

Figure 2. Phylogenetic tree obtained from minimum evolution (ME) analysis of the partial 16S rRNA gene for shrimps from the genus Lysmata, and other selected taxa from the Caridea. Numbers above or below the branches represent the bootstrap values obtained from maximum parsimony (MP) and ME analyses in PAUP* and MEGA 4.4 (MP/ME). The white and black squares represent the presence or absence, respectively, of a developed accessory branch in each species. The images of the shrimps (from top to bottom) represent Lysmata wurdemanni, Lysmata debelius, Lysmata hochi, and Lysmata galapagensis.
