Fig 3. Dorsal (A), ventral (B), and lateral (C) views of the head of the holotype of Boa atlantica sp. nov. (MNRJ 27242) from Rio de Janeiro, Atlantic coast of Brazil. https://doi.org/10.1371/journal.pone.0298159.g003

Fig 2 in The good, the bad and the boa: An unexpected new species of a true boa revealed by morphological and molecular evidence

Fig 2. Phylogenetic tree inferred by using Maximum Likelihood and general time reversible model. The matrix is composed of 39 samples from South America, being 35 samples with the four concatenated markers (cyt-b, ND4, NTF3, and ODC resulting in 2305 positions in the final dataset) and the outgroup (Charina bottae, Corallus hortulana, Epicrates cenchria, and Eunectes murinus) with cytb only). The percentage of trees in which the associated taxa clustered together is shown above the branches (bootstrap). The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. Group colours: Black: Outgroup; blue: B. occidentalis; green: B. atlantica sp. nov.; orange: B. constrictor and red: B. amarali. Photographs: A) B. c. amarali, no locality; B. c. constrictor, no locality, Brazil; C) B. c. constrictor, from Cuiabá, Mato Grosso, Brazil; B. atlantica sp. nov., from Rio de Janeiro, Brazil; B. occidentalis from Tucumán, Argentina. https://doi.org/10.1371/journal.pone.0298159.g002

FIG. 6 in Deciphering Geographical Affinity and Reconstructing Invasion Scenarios of Boa imperator on the Caribbean Island of Cozumel

FIG. 6. Bayesian clustering for two main continental clades of Boa imperator (Gulf of Mexico and Yucatán Peninsula) and the Cozumel population using STRUCTURE (Pritchard et al., 2000), based on the resulting K ¼ 3 for (A) microsatellite loci and (B) cytochrome b haplotypes. Maps show spatial interpolations of individual assignment into the three genetic clusters obtained with (C) microsatellites and (D) cyt b. Circles indicate individuals from the Gulf of Mexico clade (n ¼ 30), triangles from the Yucatán Peninsula clade (n ¼ 54), and diamonds from Cozumel (n ¼ 16).

FIG. 2. Graphical representation of the demographical reconstruction based on ABC analyses implemented in DIYABC (Cournet et al., 2014) considering different molecular datasets and priors schemes (see text for a detailed explanation).

FIG. 3 in Deciphering Geographical Affinity and Reconstructing Invasion Scenarios of Boa imperator on the Caribbean Island of Cozumel

FIG. 3. (A) Bayesian maximum clade credibility tree based on 220 unique cytochrome b haplotypes for the genus Boa inferred with BEAST (Drummond et al., 2012). Black dots represent the main clades obtained. Posterior probabilities and bootstrap support values are shown above and below the diagonal, respectively. (B) Rooted network based on the same 220 unique cyt b haplotypes, inferred with SPLITSTREE (Huson and Bryant, 2006). Arrows indicate the position of the Cozumel unique haplotypes within Boa imperator. See Data Accessibility for tree file.

FIG. 5. (A–C) Main demographic scenarios modeled with DIYABC (Cournet et al., 2014) based on two molecular datasets and the Constrained Optimization scheme of Boa imperator from Cozumel, the Yucatán Peninsula, and the Gulf of Mexico. Note that time is not to scale. (D–E) Prior distribution of parameters corresponding to the three invasion scenarios tested, where the first two axes are shown. (F–G) Posterior predictive test of model fit corresponding to Scenario 1. (H–I) Direct and (J–K) logistic approaches of the three scenario model comparisons. In all cases, left panels (D, F, H, J) and right panels (E, G, I, K) show results from the Original Reduced Datasets (ORD) and the Polymorphic Microsatellite-based Dataset (PMD), respectively.
