Genetic and behavioral factors affecting interpopulation color pattern variation in two congeneric chameleon species
<p>We conducted a study on interpopulation variation of color patterns in two congeneric chameleon species, which have an analogous life history. Both species are able to rapidly change color pattern, and context-dependent color patterns often vary across a wide geographic range. Specifically, we tested four hypotheses that can explain the observed interpopulation variation of color patterns by a series of behavioral field trials where the color patterns of individuals were recorded and later analyzed by a deep neural network algorithm. We used redundancy analysis (dbRDA) to relate genetic, spectral, and behavioral predictors to interpopulation color pattern distance. Our results showed that both isolation by distance and alternative mating tactics were significant predictors for interpopulation color pattern variation in <em>Chamaeleo</em> <em>chamaeleon</em> males. In contrast, in <em>C. dilepis</em>, the interpopulation color pattern variation was largely explained by isolation by distance, and the evidence for alternative mating tactics was absent. In both chameleon species, the environmental colors showed no evidence of influencing chameleon interpopulation color pattern variation, regardless of sex or behavioral context. This contrasting finding suggests that interpopulation context-dependent color pattern variations in each species are maintained under a different set of selective pressures or circumstances.</p>

Figure 3. Phylogenetic relationships among species of the Brookesia minima group based on nuclear and concatenated DNA sequences. Phylograms (50% majority rule consensus trees) from Bayesian inference analyses of DNA sequence alignments of (a) the nuclear genes CMOS (846 bp) and (b) RAG1 (1522 bp). (c) Phylogram from BI analysis of concatenated DNA sequences of the nuclear genes CMOS (846 bp) and RAG1 (1522 bp), and the mitochondrial genes ND2 (568 bp) and 16S (580 bp). (d) Brookesia portion of the Bayesian chronogram derived from the BEAST analyses of all four concatenated genes (see Supporting Information S1 for full chronogram with all outgroups). Posterior probabilities are indicated above branches, and bars represent 95% HPDs for mean date estimates. Units on scale are millions of years. Species of the northern clade (B. tuberculata plus the four new species described herein) are marked in colour. The trees were rooted with Brookesia nasus, and including B. brygooi and B. superciliaris as hierarchical outgroups (not shown). A, B and C refer to major clades as discussed in the text. Asterisks denote posterior probabilities of 1.0. doi:10.1371/journal.pone.0031314.g003
