  author={Antoinette J. Piaggio and Greg Spicer},
  journal={Journal of Mammalian Evolution},
Complete sequences of the mitochondrial cytochrome oxidase subunit II gene were used to construct a phylogeny for 21 of the 25 currently recognized chipmunk species. Phylogenetic analyses indicate that T. striatus (subgenus Tamias, eastern United States) and T. sibiricus (subgenus Eutamias, Asia) are distantly related to the other species (subgenus Neotamias), which constitute a western North American radiation. We discuss and compare our molecular phylogeny to previous taxonomies and present a… 
Molecular Systematics of Chipmunks (Neotamias) Inferred by Mitochondrial Control Region Sequences
The control region data set corroborated the findings of Piaggio and Spicer (2001) in finding five discrete clades, while also providing stronger bootstrap support for most terminal branches.
The results suggest that M. occultus represents an evolutionarily distinct monophyletic lineage and provide support to arguments that M .

Comparative Phylogenomic Assessment of Mitochondrial Introgression among Several Species of Chipmunks (Tamias)
Investigating extensive mtDNA introgression in western chipmunks finds no evidence for positive selection among these genomes, suggesting that selection has not been the driving force of introgressed alleles in these species.
Genomic resolution of cryptic species diversity in chipmunks
Additional population-level sequence data revealed that the so-called Crater chipmunk is a distinct species that is abundant throughout the coniferous forests of southern Idaho and does show evidence for recurrent hybridization with this and other species.
Divergence with gene flow within the recent chipmunk radiation (Tamias)
The chipmunk radiation in western North America represents an excellent mammalian example of speciation in the face of recurrent gene flow among lineages and where biogeography, habitat differentiation and mating systems suggest important roles for both ecological and sexual selection.
Phylogeographic analysis delimits three evolutionary significant units of least chipmunks in North America and identifies unique genetic diversity within the imperiled Peñasco population
It was found that N. minimus genetic diversity declined by ~87% over the last century, and the models predicted substantial future habitat contraction, including the loss of the full contemporary ranges of N. m.
Characterization of 12 polymorphic microsatellite loci for eastern chipmunks (Tamias striatus): PRIMER NOTE
12 variable microsatellite loci were developed, which amplified in three multiplexed reactions, and screened them in 27 individuals from northern Indiana, USA, to understand population dynamics of eastern chipmunks at small spatial scales.
A cladistic and biogeographic analysis of Chinese Neopsylla Wagner (Siphonaptera : Ctenophthalmidae)
Neopsylla is a paraphyletic group and Rothschildiana and Tamiophila are junior synonyms and the reasons for the changes in host and distributions of the species-groups are discussed in relation to the zoogeographic history of China.

Phylogenetic relationships among eight species of the Drosophila buzzatii species complex and D. hamatofila were determined by sequencing the mitochondrial cytochrome oxidase subunit 1, II, and III genes.
Molecular evolutionary dynamics of cytochrome b in strepsirrhine primates: the phylogenetic significance of third-position transversions.
DNA sequences of the complete cytochrome b gene are shown to contain robust phylogenetic signal for the strepsirrhine primates (i.e., lemurs and lorises), which supports the hypothesis that Malagasy lemuriforms and Afro-Asian lorisiforms each comprise clades that share a sister-group relationship.
Mammalian mitochondrial DNA evolution: A comparison of the cytochrome b and cytochrome c oxidase II genes
The evolution of two mitochondrial genes, cytochrome b and cy tochrome c oxidase subunit II, was examined in several eutherian mammal orders, with special emphasis on the orders Artiodactyla and Rodentia, where neither gene performed with a high degree of consistency in terms of the phylogenetic hypotheses supported.
System Atics of the Holarctic Chipmunks (Tamias)
Electrophoretic data for 20 proteins were obtained from 17 species of chipmunks, including all three presently recognized subgenera, and proposed phylogenetic groupings were compared with morphological groupings in an assessment of divergent and convergent evolution within the genus.
Evolution of the cytochromeb gene of mammals
Comparisons of these cytochromeb sequences support current structure-function models for this membrane-spanning protein, including that part of the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix.
Evolution of the cytochrome b gene of mammals.
Comparisons of these cytochrome b sequences support current structure-function models for this membrane-spanning protein, which suggests that the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix.
Problems of Taxonomy and Distribution in Four Species of Chipmunks
Genital bones of each species are diagnostic and, along with statistical analysis of measurements, provide a start toward correction of errors in taxonomy and distribution of these four species.
It is concluded that available data are insufficient to warrant the changes proposed by Sutton and Nadler and more extensive studies of geographic variation in genital bone morphology and allele frequencies, as well as a better theoretical framework, are needed before the evidently complex relationships within this group can be resolved.
Sequence and organization of the human mitochondrial genome
The complete sequence of the 16,569-base pair human mitochondrial genome is presented and shows extreme economy in that the genes have none or only a few noncoding bases between them, and in many cases the termination codons are not coded in the DNA but are created post-transcriptionally by polyadenylation of the mRNAs.
A Molecular Examination of Archontan and Chiropteran Monophyly
Comparative morphological and paleontological data have provided valuable information on higher-level eutherian mammal relationships, and several phylogenetic hypotheses are well supported by these
