Phylogenetic relationships among Agamid lizards of the Laudakia caucasia species group: testing hypotheses of biogeographic fragmentation and an area cladogram for the Iranian Plateau.
TLDR
Phylogenetic relationships within the Laudakia caucasia species group on the Iranian Plateau were investigated using 1708 aligned bases of mitochondrial DNA sequence from the genes encoding ND1 (subunit one of NADH dehydrogenase) and COI, and every branch of the phylogenetic tree is well supported.

Phylogenetic relationships of toads in the Bufo bufo species group from the eastern escarpment of the Tibetan Plateau: a case of vicariance and dispersal.
TLDR
The most parsimonious phylogenetic tree places the high-elevation species, B. andrewsi, as the sister taxon to the other Asian Bufo populations; these high-Elevation populations are postulated to have had a vicariant origin approximately 5 million years before present. Expand
Two novel gene orders and the role of light-strand replication in rearrangement of the vertebrate mitochondrial genome.
TLDR
Two novel mitochondrial gene arrangements are identified in an agamid lizard and a ranid frog and a mechanism involving errors in light-strand replication and tandem duplication of genes is proposed for rearrangement of vertebrate mitochondrial genes, implicate gene order as a reliable phylogenetic character.

Molecular phylogenetics of squamata: the position of snakes, amphisbaenians, and dibamids, and the root of the squamate tree.
TLDR
A molecular phylogenetic study of 69 squamate species suggests that similar states in Sphenodon and Iguania result from homoplasy, and species previously placed in Scleroglossa, Varanoidea, and several other higher taxa do not form monophyletic groups. Expand
Molecular phylogenetics and historical biogeography among salamandrids of the "true" salamander clade: rapid branching of numerous highly divergent lineages in Mertensiella luschani associated with
TLDR
Tests using four-taxon subsamples suggest that these lineages diverged nearly simultaneously in the Late Miocene, approximately 6 to 8 million years ago, when extensive uplifting of Anatolia occurred in response to the Arabian collision. Expand
Phylogenetic relationships in the iguanid lizard genus Liolaemus: multiple origins of viviparous reproduction and evidence for recurring Andean vicariance and dispersal
TLDR
Phylogenetic relationships within the iguanid lizard genus Liolaemus are investigated using 1710 aligned base positions of mitochondrial DNA sequences, representing coding regions for eight tRNAs, ND2, and portions of ND1 and COL to support at least six independent origins of viviparity. Expand
Molecular phylogenetics, tRNA evolution, and historical biogeography in anguid lizards and related taxonomic families.
TLDR
Phylogenetic analysis of evolutionary changes in the gene encoding tRNA(Cys) suggests gradual reduction of dihydrouridine (D) stems by successive deletion of bases in some lineages, which contrasts with the one observed for parallel elimination of the D-stem in mitochondrial tRNAs of eight other reptile groups, in which replication slippage produces direct repeats. Expand
Molecular phylogenetics of western North American frogs of the Rana boylii species group.
TLDR
Molecular sequence divergence suggests that the R. boylii species group is approximately 8 million years old, and reanalyses of published nuclear ribosomal DNA restriction-site data and allozymic data support a monophyletic R.Boylii group, but do not effectively resolve relationships among species within this group. Expand
Vicariant patterns of fragmentation among gekkonid lizards of the genus Teratoscincus produced by the Indian collision: A molecular phylogenetic perspective and an area cladogram for Central Asia.
TLDR
A well-supported phylogenetic hypothesis is presented for gekkonid lizards of the genus Teratoscincus, showing vicariant separation from taxa in former Soviet Central Asia and northern Afghanistan and well dated to 10 million years before present. Expand
Morphological homoplasy, life history evolution, and historical biogeography of plethodontid salamanders inferred from complete mitochondrial genomes.
TLDR
The authors' phylogenetic analyses yielded congruent trees that contrast with the traditional morphology-based taxonomy; the monophyly of three of four major groups is rejected and they suggest surprising evolutionary lability in traits previously interpreted to be conservative. Expand
