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.
