Figure 1. A in Evolutionary History of the Subgenus Mus in Eurasia with Special Emphasis on the House Mouse Mus musculus
Figure 1. A sketch of the evolutionary patterns of lineage differentiation among species in the genus Mus based on molecular phylogenetic analysis of nuclear gene sequences (Suzuki et al., 2004; Shimada et al., 2010). The tree shows the four subgenera of the genus Mus and the four species groups (SGs) of the subgenus Mus: M. musculus, M. booduga, M. lepidoides, and M. caroli (previously termed as M. cervicolor SG), representing four geographic regions of the Palaearctic region, Indian subcontinent, Myanmar, and Southeast Asia, respectively. The taxon previously regarded as "M. cervicolor" in Thailand is here referred to as "M. sp.", due to uncertainty regarding the taxonomic status of the sampled specimens (see main text). The estimated divergence times for the subgenera and species groups are approximately 5 and 2.5 million years ago, respectively (Shimada et al., 2010). Specific habitat transitions from grasslands to forests and arid areas are marked for the species lineages of M. cookii and M. lepidoides. Predicted dispersal events between geographic regions are indicated with dotted arrows.

Figures 2–4. Assessment of population genetic structure using concatenated sequences (4302 bp) of seven nuclear genes. (2) Positions of the analysed regions (open triangles) in seven genes on murine chromosome 8 (Nunome et al., 2010; Kodama et al., 2013). (3) Neighbour- Net network based on concatenated sequences from 98 Mus musculus, showing haplogroups representing the subspecies groups Mus musculus domesticus (DOM), Mus musculus castaneus (CAS), and Mus musculus musculus (MUS) as well as recombinant haplotypes (Re) (Kodama et al., 2013). In the network, the level of diversity of CAS is markedly higher than those of DOM and MUS, yielding five distinct phylogroups A–E. Scale bar indicates genetic divergence. (4) Approximate geographic ranges of the five subclusters of CAS. Localities where samples used in this analysis were collected are marked with open and filled circles, representing the mitochondrial haplogroup CAS-1 and all other types, respectively (Kodama et al., 2013). The phylogroups A–E of CAS showed rough geographical distributions and one of them, phylogroup D, comprised the haplotypes recovered from a large geographical area of Southeast Asia, south China, and Indonesia and can be characterized as the lineage dispersed with prehistoric human movement (arrow; Kodama et al., 2015). Note that subcluster D (arrow in Fig. 3) shows a broad distribution range in Southeast Asia and the southern part of East Asia. In the Neighbor-Net network, this subcluster exhibits limited divergence among haplotypes.

Data from: Strong effects of lab-to-field environmental transitions on the bacterial intestinal microbiota of Mus musculus are modulated by Trichuris muris infection
<p>Studies of controlled lab animals and natural populations represent two insightful extremes of microbiota research. We bridged these two approaches by transferring lab-bred female C57BL/6 mice from a conventional mouse facility to an acclimation room and then to an outdoor enclosure, to investigate how the gut microbiota changes with environment. Mice residing under constant conditions served as controls. Using 16S rRNA sequencing of fecal samples, we found that the shift in temperature and humidity, as well as exposure to a natural environment, increased microbiota diversity and altered community composition. Community composition in mice exposed to high temperatures and humidity diverged as much from the microbiota of mice housed outdoors as from the microbiota of control mice. Additionally, infection with the nematode <i>Trichuris muris</i> modulated how the microbiota responded to environmental transitions: The dynamics of several families were buffered by the nematodes, while invasion rates of two taxa acquired outdoors were magnified. These findings suggest that gut bacterial communities respond dynamically and simultaneously to changes within the host's body (e.g., the presence of nematodes) and to changes in the wider environment of the host.</p>

Uttar Pradesh, India" ~ http://www.britishmuseum.org/research/collection_online/collection_object_details.aspx?objectId=246697&partId=1&images=true (thanks to Dan Pett for pointing me to the above record!) Description from FLickr user [plnghl](https://www.flickr.com/photos/plnghl/): "Ganesha is one of the most popular Hindu gods and is the son of Parvati. He is the lord of beginnings as well as the placer and remover of obstacles. He usually carries one of his own tusks in one hand and a bowl of sweets; here he also carries a rosaryand and an axe. In myth, Ganesha received his elephant's head when, in a temper, Shiva cut off his human head. Later, he swore to replace it with the head of the first creature he encountered, which was an elephant." ~ https://www.flickr.com/photos/134648998@N04/23437641744 Source: Objaverse 1.0 / Sketchfab

Data from: Density matters: How population dynamics of house mice (Mus musculus) inform the epidemiology of Leptospira
<p>Rodents are maintenance hosts of numerous pathogens, and both their density and the pathogen prevalence determine the risk they pose to other animals or humans. However, density is often overlooked. We investigated a capture-mark-recapture-sampling strategy to study introduced mice (<em>Mus musculus</em>) and <em>Leptospira</em> as a model and demonstrate the advantages of a combined approach. We estimated population density and <em>Leptospira</em> prevalence in mice in a replicated longitudinal survey conducted between 2016 and 2018. Capture-mark-recapture sessions were undertaken at two sites in Spring and Autumn and blood and kidney samples were collected at the end of each session. Mouse density and areas of activity were estimated using spatially explicit capture-recapture (SECR) models and both were compared between <em>Leptospira</em> positive and negative mice. <em>Leptospira </em>exposure and shedding status were estimated using Microscopic Agglutination Test, and a combination of culture and <em>lipL32</em> PCR on kidneys. <em>Leptospira </em>prevalence was higher in spring (83% to 86%) than in autumn (31% to 37%) and mouse densities simultaneously varied from 3.6 to 55.9/ha. However, despite these variations in prevalence and density, the density of infected animals remained relatively constant over time (3 to 8/ha). Shedding or being seropositive was also associated with the activity of mice. Shedding or seropositive mice had a larger activity area, and seropositive mice were trapped on average one day earlier than seronegative mice. </p> <p><em>Synthesis and applications</em>. Our results show how understanding the population dynamics of pathogen-carrying rodents is critical in epidemiology. The wider movement patterns and easier encounters of positive mice highlight the possibility of biases in classical prevalence surveys and have implications for disease transmission within and between species. Importantly, and quite counter-intuitively, <em>Leptospira</em> prevalence was negatively associated with mouse density, resulting in a constant density of shedders that contradicts the conventional view of higher exposure risk at high rodent density. More broadly, such hybrid sampling designs can improve animal and disease control policies and better inform modelling studies by providing more parameter estimates than classical prevalence surveys.</p>
