Figure 3 in Rivaling the World's Smallest Reptiles: Discovery of Miniaturized and Microendemic New Species of Leaf Chameleons (Brookesia) from Northern Madagascar
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

Orange (dry forest) and green (rainforest) show remaining primary vegetation in 2003–2006, modified from the Madagascar Vegetation Mapping Project (http://www.vegmad.org). doi:10.1371/journal.pone.0031314.g001
Figure 6 in Rivaling the World's Smallest Reptiles: Discovery of Miniaturized and Microendemic New Species of Leaf Chameleons (Brookesia) from Northern Madagascar
Figure 6. Hemipenes of species in the Brookesia minima group. The photos show for each species, a general view of the organs and a close-up. For B. desperata, the inset picture shows a non-turgid everted hemipenis where the two apex projections are very prominent. Note that also several other of the shown preparations are not fully turgid, especially in B. ramanantsoai and B. micra. In two other species (B. confidens and B. tristis) the shown hemipenes might not be fully everted. doi:10.1371/journal.pone.0031314.g006

FIGURE 2 in Two new species of leaf-tailed geckos (Uroplatus) from the Tsaratanana mountain massif in northern Madagascar
FIGURE 2. Tails of specimens of all described species of the Uroplatus ebenaui group, including the newly described U. fotsivava sp. nov. (previously U. ebenaui [Ca1]) and U. kelirambo sp. nov. (previously U. ebenaui [Ca2]), as well as U. ebenaui [Ca3] and U. ebenaui [Ca4]. All tails sized to scale (scale bar 2 mm). Female specimens are labelled with ♀. All other specimens are males.
FIGURE 1 in Two new species of leaf-tailed geckos (Uroplatus) from the Tsaratanana mountain massif in northern Madagascar
FIGURE 1. Bayesian inference phylogenetic tree of the Uroplatus ebenaui group based on a 2313 bp alignment of four concatenated mitochondrial gene fragments (ND4, 12S rRNA, 16S rRNA, COX1) (mtDNA). Only posterior probability values of 0.95 or greater are displayed at nodes. An outgroup (U. alluaudi) was used for rooting but omitted from the tree for graphical reasons. Note that the phylogenetic position of Uroplatus ebenaui [Ca8] from Ambohitantely is tentative, because only sequences of a single gene fragment were available from this sample. To the right of the tree is a haplotype network independently calculated from sequences of the nuclear gene CMOS showing concordant differentiation (absence of haplotype sharing) among the target species described herein and all nominal species of the U. ebenaui group.
