Fig 5 in Description of a New Galapagos Giant Tortoise Species (Chelonoidis; Testudines: Testudinidae) from Cerro Fatal on Santa Cruz Island
Fig 5. Frequency distribution of genetic distances between different Galapagos giant tortoise species (A: microsatellite DNA, B: mitochondrial DNA). For each histogram, a dark gray column indicates where the observed genetic distance between the Cerro Fatal and Reserva tortoises falls. Left: Microsatellite genetic distances calculated from purebred individuals in the reference measured using FST (top) or RST (below). Right: DNA sequence genetic distances based on mtDNA haplotypes from purebred individuals in the reference database, measured using uncorrected p-distances (top), or maximum likelihood (ML)-corrected distances (below).
Fig 2 in Description of a New Galapagos Giant Tortoise Species (Chelonoidis; Testudines: Testudinidae) from Cerro Fatal on Santa Cruz Island
Fig 2. (A) Bayesian Inference (BI) tree reconstructed from the dataset including all unique mtDNA control region haplotypes previously sampled from extant and extinct species as well as the three museum specimens of giant Galapagos tortoises analyzed in this study. Numbers on branches indicate posterior probabilities. Only the nodal support values for the major lineages are presented. Red and green colors identify museum samples analyzed in the present and previous studies, respectively. (B) Haplotype network showing matrilineal diversity recovered from 70 sequences of C. porteri from Reserva, 51 sequences of the lineage from Cerro Fatal, and 2 sequences of C. chathamensis from San Cristóbal Island. Twenty-five inferred mutations separate the haplogroups of Chelonoidis sp. nov. from Cerro Fatal from the ones from C. porteri from Reserva.

Light gray area connecting the distribution areas of the two species indicates agricultural land. Modified from Russello et al. [11].

Fig 4. Genetic membership from Bayesian assignment tests in STRUCTURE for the three museum individuals, relative to the genotypic database representing the Cerro Fatal (black) and Reserva (white) giant tortoise populations. Each bar represents an individual and the proportional color of each bar represents the percentage membership (i.e., Q-value) in each of the reference clusters. Museum individuals include the C. porteri holotype (#) and the two Cerro Fatal specimens tested as putative candidates for the Chelonoidis sp. nov. holotype (*).

FIGURE 2. Phylogenetic trees of the genus Chelonoidis, including the C. chilensis complex, obtained by three different criteria. A: Maximum Parsimony, B: Maximum Likelihood, C: Bayesian Inference. The numbers above the nodes indicate bootstrap support scores (A and B) and posterior probability scores (C). Clade colors refer to the corresponding eco–regions (see Fig. 1).
FIGURE 1 in Phylogenetic and divergence time analysis of the Chelonoidis chilensis complex (Testudines: Testudinidae)
FIGURE 1. Map of Argentina showing the localities from which the tissue samples were taken. Different colors indicate different eco–regions. Legends near sample localities are in accordance with the haplotypes shown in the phylogenetic trees (Fig. 2).
FIGURE 3 in Phylogenetic and divergence time analysis of the Chelonoidis chilensis complex (Testudines: Testudinidae)
FIGURE 3. Ultrametric trees obtained by the two-step method of McCartney & Barreto (2010), showing the divergence times within the family Testudinidae (A) and the divergence times within the C. chilensis complex (B). Numbers above the nodes indicate median of node ages, red numbers below the nodes indicate the clades belonging to the genus Chelonoidis (see table 5).
Fig. 1 in Red- and yellow-footed tortoises, Chelonoidis carbonaria and C. denticulata (Reptilia: Testudines: Testudinidae), in South American savannahs and forests: do their phylogeographies reflect distinct habitats?
Fig. 1 Approximate ranges of Chelonoidis carbonaria and C. denticulata (modified from Iverson 1992) and geographic distribution of haplotypes. Locality numbers refer to Appendix 1. Question marks indicate that the southern part of the range of C. carbonaria might be connected with the northern part. Symbols for C. carbonaria correspond to haplotype clades (Fig. 2); upper-case letters indicate geographic origin within the range (N, north; NE, northeast; etc.)

Figure 12 in The Miocene tortoise Testudo catalaunica Bataller, 1926, and a revised phylogeny of extinct species of genus Testudo (Testudines: Testudinidae)
Figure 12. Phylogenetic tree of Testudo spp. included in this study, based on the most parsimonious cladogram depicted in Figure 11 and further indicating the approximate stratigraphical range of the depicted taxa. Age boundaries (in million years ago or mega-annums, Ma) for epochs, stages, European land mammal ages (ELMA) and Mammal Neogene units (MN) are based on Hilgen, Lourens & Van Dam (2012; see this reference for the full name of stages and ELMA abbreviated in this figure). For illustration purposes, divergence times are arbitrarily set one million years before the oldest record of each clade. Similarly, successive branching points within ghost lineages are separated by one million years to avoid their collapse in the figure. For full taxon names, see Table 3.
