Species delimitation using Bayes factors: simulations and application to the Sceloporus scalaris species group (Squamata: Phrynosomatidae).
TLDR
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.
Evolutionary drivers of phylogeographical diversity in the highlands of Mexico: a case study of the Crotalus triseriatus species group of montane rattlesnakes
Aim  To assess the genealogical relationships of widespread montane rattlesnakes in the Crotalus triseriatus species group and to clarify the role of Late Neogene mountain building and Pleistocene
Coalescent species delimitation in milksnakes (genus Lampropeltis) and impacts on phylogenetic comparative analyses.
TLDR
This study examines how delimitation of previously unrecognized diversity in the milksnake (Lampropeltis triangulum) and use of a species-tree approach affects both estimation of the Lampropelti phylogeny and comparative analyses with respect to the timing of diversification.
Phylogeography of Middle American gophersnakes: mixed responses to biogeographical barriers across the Mexican Transition Zone
TLDR
Inferences of phylogeographical structure and estimates of divergence times for three species of gophersnakes distributed across the Mexican Transition Zone are used to evaluate the postulated association of three Neogene geological events and Pleistocene climate change with inter‐ and intraspecific diversification.
High phylogenetic utility of an ultraconserved element probe set designed for Arachnida
TLDR
This probe set will open the door to phylogenomic and population genomic studies across the arachnid tree of life, enabling systematics, species delimitation, species discovery and conservation of these diverse arthropods.
Cryptic diversity and discordance in single‐locus species delimitation methods within horned lizards (Phrynosomatidae: Phrynosoma)
TLDR
A large data set of mitochondrial ND4 sequences from horned lizards is compiled to elucidate congruence using four tree‐based (single‐threshold GMYC), multiple‐th threshold GMYC, bPTP, mPTP and one distance‐based species delimitation models, suggesting that the mP TP model may be preferable in empirical data sets with highly uneven sampling or large differences in effective population sizes of species.
Ephemeral Pleistocene woodlands connect the dots for highland rattlesnakes of the Crotalus intermedius group
Aim  To test how Pleistocene climatic changes affected diversification of the Crotalus intermedius species complex.
