Testing phylogenetic and biogeographic hypotheses in the widespread genus Microtus through parsimony and likelihood analysis of mtDNA-sequence data found monophyly of North American species was supported, albeit weakly, and basal relationships were not robust. Expand
Genetic footprints of demographic expansion in North America, but not Amazonia, during the Late Quaternary
This work used coalescence theory to examine the genetic evidence, or lack thereof, for late Pleistocene refugia of boreal North American and tropical Amazonian mammals and found substantial and concordant evidence of demographic expansion in North American mammals, particularly at higher latitudes.

Holarctic phylogeography of the root vole (Microtus oeconomus): implications for late Quaternary biogeography of high latitudes
A species‐wide phylogeographical study of the root vole (Microtus oeconomus) was performed using the whole 1140 base pair mitochondrial (mt) cytochrome b gene. We examined 83 specimens from 52Expand
MtDNA Evidence for Repeated Pulses of Speciation Within Arvicoline and Murid Rodents
We examined temporal aspects of phylogenetic relationships among 5 murid rodent subfamilies and 11 arvicoline genera based on DNA sequences of the cytochrome b gene (n = 92) and ND4 gene (n = 17). WeExpand
Phylogeography of a post‐glacial colonizer: Microtus longicaudus (Rodentia: Muridae)
The results suggest that the close relationships among haplotypes within northern subclades are a result of recent colonization, whereas higher among‐subclade divergence is caused by genetic differentiation during prolonged periods of isolation, possibly as a consequence of mid‐Pleistocene climatic events.

Phylogeography of the deer mouse (Peromyscus maniculatus) provides a predictive framework for research on hantaviruses.
The phylogeography of P. maniculatus provides a framework for interpreting geographical variability, not only in hosts, but also in associated viral variants and disease transmission, and an opportunity to predict the potential geographical distribution of newly emerging viral strains. Expand
Phylogeography of lemmings (Lemmus): no evidence for postglacial colonization of Arctic from the Beringian refugium
There is little evidence for the direct effect of the last glaciation on the level of genetic variation and allele genealogy in lemmings on a regional geographical scale, implying that the population genetic models of postglacial colonization suggested for temperate taxa might have limited applicability for Arctic species.

Divergent lineage of a novel hantavirus in the banana pipistrelle (Neoromicia nanus) in Côte d'Ivoire
Phylogenetic analysis of partial L-segment sequences revealed that the newfound hantavirus, designated Mouyassué virus (MOUV), was highly divergent and basal to all other rodent- and soricomorph-borne hantviruses, except for Nova virus in the European common mole. Expand
The molecular phylogenetics of tuco-tucos (genus Ctenomys, Rodentia: Octodontidae) suggests an early burst of speciation.

Calibrations based on the fossil record suggest that the mitochondrial cytochrome b of these caviomorphs has evolved at a rapid rate, comparable to those proposed for Mus-Rattus, and three to four times higher than ungulate rates. Expand
Postglacial expansion of the southern red‐backed vole (Clethrionomys gapperi) in North America
Molecular investigations of a variety of organisms show that processes of postglacial colonization of boreal regions were more complex than initially thought and may reflect the signal of a high latitude refugial population. Expand
