Toward a tree-of-life for the boas and pythons: multilocus species-level phylogeny with unprecedented taxon sampling

Snakes in the families Boidae and Pythonidae constitute some of the most spectacular reptiles and comprise an enormous diversity of morphology, behavior, and ecology. While many species of boas and pythons are familiar, taxonomy and evolutionary relationships within these families remain contentious...

While many species of boas and pythons are familiar, taxonomy and evolutionary relationships within these families remain contentious and fluid. A major effort in evolutionary and conservation biology is to assemble a comprehensive Tree-of-Life, or a macro-scale phylogenetic hypothesis, for all known life on Earth. No previously published study has produced a species-level molecular phylogeny for more than 61% of boa species or 65% of python species. Using both novel and previously published sequence data, we have produced a species-level phylogeny for 84.5% of boid species and 82.5% of pythonid species, contextualized within a larger phylogeny of henophidian snakes. We obtained new sequence data for three boid, one pythonid, and two tropidophiid taxa which have never previously been included in a molecular study, in addition to generating novel sequences for seven genes across an additional 12 taxa. We compiled an 11-gene dataset for 127 taxa, consisting of the mitochondrial genes CYTB, 12S, and 16S, and the nuclear genes bdnf, bmp2, c-mos, gpr35, rag1, ntf3, odc, and slc30a1, totaling up to 7561 base pairs per taxon. We analyzed this dataset using both maximum likelihood and Bayesian inference and recovered a well-supported phylogeny for these species. We found significant evidence of discordance between taxonomy and evolutionary relationships in the genera Tropidophis, Morelia, Liasis, and Leiopython, and we found support for elevating two previously suggested boid species. We suggest a revised taxonomy for the boas (13 genera, 58 species) and pythons (8 genera, 40 species), review relationships between our study and the many other molecular phylogenetic studies of henophidian snakes, and present a taxonomic database and alignment which may be easily used and built upon by other researchers.application/pdfhttps://doi.org/10.1016/j.ympev.2013.11.011ISSN: 1055-7903EISSN: 1095-9513https://repository.urosario.edu.co/handle/10336/27121engElsevier213201Molecular Phylogenetics and EvolutionVol. 71Molecular Phylogenetics and Evolution, ISSN: 1055-7903;EISSN: 1095-9513, Vol.71 (2014); pp. 201-213https://www.sciencedirect.com/science/article/abs/pii/S1055790313004284Restringido (Acceso a grupos específicos)http://purl.org/coar/access_right/c_16ecMolecular Phylogenetics and Evolutioninstname:Universidad del Rosarioreponame:Repositorio Institucional EdocURAlethinophidiaBoidaeEvolutionPhylogeneticsPythonidaeSnakesToward a tree-of-life for the boas and pythons: multilocus species-level phylogeny with unprecedented taxon samplingHacia un árbol de la vida para las boas y pitones: filogenia multilocus a nivel de especie con muestreo de taxón sin precedentesarticleArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501Reynolds, R.GrahamNiemiller, Matthew L.Revell, Liam J.10336/27121oai:repository.urosario.edu.co:10336/271212021-06-03 00:50:06.022https://repository.urosario.edu.coRepositorio institucional EdocURedocur@urosario.edu.co
