Complete ND2 and partial ND4 and cytochrome b mitochondrial DNA (mtDNA) sequences were analysed to evaluate the phylogeographic patterns of common garter snakes (Thamnophis sirtalis) in western North America. This species is widely distributed throughout North America, and exhibits extensive phenotypic variation in the westernmost part of its range. The overall phylogeographic pattern based on mtDNA sequences is concordant with results from studies of other species in this region, implicating…

Novel patterns of historical isolation, dispersal, and secondary contact across Baja California in the Rosy Boa (Lichanura trivirgata).
Post-glacial recolonization of the Great Lakes region by the common gartersnake (Thamnophis sirtalis) inferred from mtDNA sequences.
Extensive genetic divergence in the East Asian natricine snake, Rhabdophis tigrinus (Serpentes: Colubridae), with special reference to prominent geographical differentiation of the mitochondrial cytochrome b gene in Japanese populations
TLDR
Investigation of intraspecific phylogenetic relationships in the natricine snake, Rhabdophis tigrinus, suggests substantial genetic divergences among population assemblages from those three regions and considers both lateralis from the continent and formosanus from Taiwan as distinct full species based on the evolutionary species concept.
Molecular phylogeography of Apalone spinifera (Reptilia, Trionychidae)
TLDR
The nuclear data suggest that taxonomic elevation of the two mitochondrial clades would be currently unjustified, and molecularly confirmed a geographical boundary between these two clades in Oklahoma, and developed a phylogeographical hypothesis that invokes stream capture.
PHYLOGEOGRAPHY OF NORTHERN POPULATIONS OF THE PACIFIC
TLDR
Phylogeography of northern populations of the Pacific treefrog, Pseudacris regilla, was investigated using mitochondrial cytochrome b sequence data, finding the overall pattern of divergence was not de- tected by previous morphological and protein analysis and is concordant with many other Northwest taxa.
Range-wide phylogeographic analysis of the spotted frog complex (Rana luteiventris and Rana pretiosa) in northwestern North America.
Combining Phylogeography with Distribution Modeling: Multiple Pleistocene Range Expansions in a Parthenogenetic Gecko from the Australian Arid Zone
TLDR
A detailed phylogeographic study of a vertebrate parthenogen, the Australian gecko Heteronotia binoei, in combination with statistical and biophysical modeling of its distribution during the last glacial maximum is presented, illustrating the power of combining complementary analytical approaches.

PHYLOGEOGRAPHY OF NORTHERN POPULATIONS OF THE PACIFIC TREEFROG, PSEUDACRIS REGILLA
TLDR
Phylogeography of northern populations of the Pacific treefrog was investigated using mitochondrial cytochrome b sequence data, finding the overall pattern of divergence was not detected by previous morphological and protein analysis and is concordant with many other Northwest taxa.
Limited phylogeographic structure in the flightless ground beetle, Calathus ruficollis, in southern California
TLDR
Mismatch distributions and Fu's Fs indicate range expansion of several populations, suggesting that some structure may have been obscured by recent exchange, and the population of C. ruficollis on Santa Cruz Island, which might have been expected to be isolated, shares several haplotypes with mainland populations, appearing to represent multiple colonizations.

Historical biogeography of the Western Rattlesnake (Serpentes: viperidae: Crotalus viridis), inferred from mitochondrial DNA sequence information.
TLDR
The phylogeny should represent the basis for further studies on the causes of geographical variation in this complex and allow the inferences that small body size evolved twice and that the ability of one population to secrete highly lethal toxins related to Mojave toxin arose within the complex.
PHYLOGEOGRAPHY OF THE TAILED FROG (ASCAPHUS TRUEI): IMPLICATIONS FOR THE BIOGEOGRAPHY OF THE PACIFIC NORTHWEST
TLDR
The depth of divergence between inland and coastal populations supports the persistence of mesic forests within the inland Pacific Northwest throughout the Pleistocene and is congruent with patterns found in several other mesic forest species.

Molecular systematics of short-horned lizards: biogeography and taxonomy of a widespread species complex.
TLDR
High levels of genetic variation found in population comparisons are in accord with high levels of morphological variation in this species group; however, only in the Pacific Northwest region is there spatial congruence between these phylogenetic results and subspecific ranges based on previous morphological studies.
THE POLYTYPIC SPECIES REVISITED: GENETIC DIFFERENTIATION AND MOLECULAR PHYLOGENETICS OF THE TIGER SALAMANDER AMBYSTOMA TIGRINUM (AMPHIBIA: CAUDATA) COMPLEX
TLDR
A phylogenetic analysis of the Ambystoma tigrinum complex is presented, based on approximately 840 base pairs of mitochondrial‐DNA sequence from the rapidly evolving D‐loop and an adjacent intron, which suggests that these eight lineages diverged during a period of rapid cladogenesis.
Phylogeography of the California mountain kingsnake, Lampropeltis zonata (Colubridae)
TLDR
Examination of colour pattern variation in 321 living and preserved specimens indicated that the two main colour pattern characters used to define the subspecies of L. zonata are so variable that they cannot be reliably used to differentiate taxonomic units within this complex, which calls into question the recognition of seven geographical races of this snake.
Cytochrome b Phylogeny Does Not Match Subspecific Classification in the Western Terrestrial Garter Snake, Thamnophis elegans
TLDR
A 307-bp fragment of the mitochondrial cytochrome b gene from 42 individuals representing 14 populations of the western terrestrial garter snake, Thamnophis elegans, did not match subspecific classification of the populations, but it did yield geographically proximate groups.
MITOCHONDRIAL DNA PHYLOGEOGRAPHY OF THE POLYTYPIC NORTH AMERICAN RAT SNAKE (ELAPHE OBSOLETA): A CRITIQUE OF THE SUBSPECIES CONCEPT
TLDR
Mitochondrial DNA analysis of the polytypic snake, Elaphe obsoleta, yields well-supported clades that do not conform to any of the currently accepted subspecies, and underscores the potential problems of recognizing subspecies based on one or a few characters.
POSTGLACIAL RANGE FLUCTUATION, GENETIC SUBDIVISION AND SPECIATION IN THE WESTERN NORTH AMERICAN SPOTTED FROG COMPLEX, RANA PRETIOSA
TLDR
Speciation in these frogs may not be correlated with morphological evolution since comparatively neutral allozyme changes may be established more rapidly than changes in morphology.
