FIGURE 7 in Rediscovery of Mus nitidulus Blyth (Rodentia: Muridae), an endemic murine rodent of the central basin of Myanmar
FIGURE 7. Scanning electron micrographs of upper (top row) and lower (bottom row) molar rows of three species of mice. Taxon and specimens details: M.n. = Mus nitidulus (CM30496); M.c. = M. cervicolor subsp. (CM30655; Vientiane, Laos); M.f. = M. fragilicauda (CM30219; Lamam, Laos). The close similarity in molar morphology between M. nitidulus and M. fragilicauda is clearly illustrated. Other abbreviations: M3 = upper third molar; m3 = lower third molar; pc = posterior cingulum; t1-t6 = cusps t1, t3 etc. The central row of cusps on M1 are cusps t2, t5 and t8. The molar rows of each species are arbitrarily rescaled to approximately the same total lengths.

Insights into Mus musculus population structure across Eurasia revealed by whole-genome analysis
<p>For more than 100 years, house mice (Mus musculus) have been used as a key animal model in biomedical research. House mice are genetically diverse, yet their genetic background at the global level has not been fully understood. Previous studies suggested that they originated in South Asia and diverged into three major subspecies almost simultaneously, approximately 350,000–500,000 years ago; however, they have spread across the world with the migration of modern humans in prehistoric and historic times (∼10,000 years ago to present), and undergone secondary contact, which have complicated the genetic landscape of wild house mice. In this study, we sequenced the whole genomes of 98 wild house mice collected from Eurasia, particularly East Asia, Southeast Asia, and South Asia. We found that although wild house mice consist of three major genetic groups corresponding to the three major subspecies, individuals representing admixture between subspecies are much more ubiquitous than previously recognized. Furthermore, several samples showed an incongruent pattern of genealogies between mitochondrial and autosomal genomes. Using samples likely retaining the original genetic components of subspecies with least admixture, we estimated the pattern and timing of divergence among the subspecies. The results are important for understanding the genetic diversity of wild mice on a global level and the information will be particularly useful in future biomedical and evolutionary studies using laboratory mice established from these wild mice.</p>
Data for: Population structure and inbreeding in wild house mice (Mus musculus) at different geographic scales
<p>House mice (<em>Mus musculus</em>) have spread globally as a result of their commensal relationship with humans. In the form of laboratory strains, both inbred and outbred, they are also among the most widely-used model organisms in biomedical research. Although the general outlines of house mouse dispersal and population structure are well known, details have been obscured by either limited sample size or small numbers of markers. Here we examine ancestry, population structure, and inbreeding using SNP microarray genotypes in a cohort of 814 wild mice spanning five continents and all major subspecies of <em>Mus</em>, with a focus on <em>M. m. domesticus</em>. We find that the major axis of genetic variation in <em>M. m. domesticus</em> is a south-to-north gradient within Europe and the Mediterranean. The dominant ancestry component in North America, Australia, New Zealand, and various small offshore islands is of northern European origin. Next, we show that inbreeding is surprisingly pervasive and highly variable, even between nearby populations. By inspecting the length distribution of homozygous segments in individual genomes, we find that inbreeding in commensal populations is mostly due to consanguinity. Our results offer new insight into the natural history of an important model organism for medicine and evolutionary biology.</p>
