Recovering complete mitochondrial genome sequences from RNA-Seq: A case study of Polytomella non-photosynthetic green algae. The consensus tree was plotted and visualized with FigTree ver. Humbert, ed. Markow TA.

True toads of the genus Rhinella are among the most common and diverse group of Neotropical anurans. These toads are widely distributed throughout South America, inhabiting a great diversity of environments and ecoregions. Currently, however, the genus is defined solely on the basis of molecular characters, and it lacks a proper diagnosis. Although some phenetic species groups have traditionally been recognized within Rhinella, the monophyly of some of them have been rejected in previous phylogenetic analyses, and many species remain unassigned to these poorly defined groups.

Additionally, the identity and taxonomy of several species are problematic and hinder the specific recognition and description of undescribed taxa. The comparative analysis of what is meant by a phylogenetic group datasets revealed unidirectional mitochondrial introgressions what is meant by a phylogenetic group an unknown parental species into R. We performed total-evidence phylogenetic analyses that included revised molecular four mitochondrial and five nuclear genes and phenotypic 90 characters datasets for 83 nominal species of Rhinella, plus several undescribed and problematic species and multiple outgroups.

Results demonstrate that Rhinella was nonmonophyletic due to the position of R. Once R. One of these is moderately supported and includes species of the former R. The other major clade is strongly supported and composed of all the species from the non-monophyletic R. Consistent with these results, we define eight species groups of Rhinella that are mostly diagnosed by phenotypic synapomorphies in addition to a combination of morphological character states. Rhinella sternosignata is the only species that remains wgat to any group.

We also synonymize nine species, treat mesnt former subspecies as full species, and suggest that 15 lineages represent putative undescribed species. Lastly, we discuss the apparently frequent meaning of bandwagon effect in urdu of hybridization, deep mitochondrial divergence, and ghost introgression; the incomplete phenotypic evidence including putative character systems that could be used for future phylogenetic analyses ; and the validity of the known fossil record of Rhinella as a source of calibration points for divergence dating analyses.

Because Quaternary topographical patterns in the Central Andes have remained unchanged for the last 2—3 MYA, a plausible explanation for this late Pleistocene vicariant event is related with glacial-interglacial cycles [ 98 ].

Editor in Chief Dra. Chaparro, Juan C. The first possible explanation is the simple fact that numbers of informative sites within a single locus are insufficient to accurately estimate phylogenetic relationships, particularly in groups of recently diverged species: what is meant by a phylogenetic group support for gene trees was poorer than for the tree based on complete mitogenomes.

Codon usage is highly biased suggesting that synonymous sites cannot be considered strictly neutral and that some sort of natural what is meant by a phylogenetic group for translational accuracy governs codon usage [ 75 ]. Servicios Personalizados Revista. Besides the impact on air temperature, periods of ice advance in the Central Andes generally were periods of negative water balance in the Pacific coastal regions west to the Central Andes [ ], and a positive water balance in the Central Andes, as evidenced by deeper and fresher conditions in Lake Titicaca [ ] see S2 Fig. Numbers on each node are the time estimates.
