Partitioned Bayesian analyses, partition choice, and the phylogenetic relationships of scincid lizards.
A criterion, based on the Bayes factor, for selecting among competing partitioning strategies is proposed and tested and it is demonstrated that how one partitions the data is shown to be a greater concern than simply the overall number of partitions.
Molecular systematics of the Eastern Fence Lizard (Sceloporus undulatus): a comparison of Parsimony, Likelihood, and Bayesian approaches.
An extensive phylogenetic analysis of the wide-ranging and geographically variable Eastern Fence Lizard suggests "S. undulatus" represents at least four lineages that should be recognized as evolutionary species.
Hylid frog phylogeny and sampling strategies for speciose clades.
The results show that hemiphractine hylids are not closely related to other hyLids and should be recognized as a distinct family, and that the speciose genus Hyla is polyphyletic, but that its species can be arranged into three monophyletic genera.

Overall, this study illustrates how two general principles (niche conservatism and the time‐for‐speciation effect) may help explain the latitudinal diversity gradient as well as many other diversity patterns across taxa and regions.
Phylogenetic Relationships of Whiptail Lizards of the Genus Cnemidophorus (Squamata: Teiidae): A Test of Monophyly, Reevaluation of Karyotypic Evolution, and Review of Hybrid Origins
Phylogenetic relationships of the whiptail lizards of the genus Cnemidophorus are inferred based on a combined analysis of mitochondrial DNA, morphology, and allozymes, and a review of the current knowledge of teioid unisexuals and their hybrid origins is provided.
Species delimitation using Bayes factors: simulations and application to the Sceloporus scalaris species group (Squamata: Phrynosomatidae).
Bayes factor delimitation of species showed improved performance when species limits are tested by reassigning individuals between species, as opposed to either lumping or splitting lineages, and marginal-likelihood estimates via PS or SS analyses provide a useful and complementary alternative to existing species delimitation methods.
WHY DOES A TRAIT EVOLVE MULTIPLE TIMES WITHIN A CLADE? REPEATED EVOLUTION OF SNAKELIKE BODY FORM IN SQUAMATE REPTILES
- J. Wiens, M. Brandley, T. Reeder
- Biology, Environmental ScienceEvolution; international journal of organic…
The repeated origins of snakelike squamates appear to be associated with the in situ evolution of these two ecomorphs on different continental regions, with very little dispersal of most limb-reduced lineages between continental regions.
Rapid development of multiple nuclear loci for phylogenetic analysis using genomic resources: an example from squamate reptiles.
