The paper identifies a mutation in the MC1R gene responsible for seasonal camouflage in least weasels and shows it was maintained by spatially varying selection.

The paper compares lysosomal characteristics between fibroblasts of two mouse species, finding elevated lysosomal mass and enzyme activity in M. spretus compared to M. musculus.

This study uses mitochondrial DNA and whole-genome sequence data to analyze species boundaries, diversification times, and hybridization in Andean leaf-eared mice, finding that diversification coincided with Pleistocene climate changes and ongoing hybridization between two species.

This study investigates phylogenomic discordance in Old World mice and rats, finding that genetic linkage and selection influence phylogenetic patterns and that assuming a single species tree can lead to errors in detecting positive selection.

This study compares hybrid male sterility in two rodent crosses, finding stage-dependent misexpression and sex-chromosome overexpression, suggesting distinct mechanisms in dwarf hamsters and house mice.

This study examines how sperm competition intensity influences sperm morphology and reproductive gene evolution across murine rodents, finding that smaller testes correlate with faster molecular evolution due to relaxed selection.

The paper reports the discovery of Andean mice at extreme elevations, surpassing previously assumed range limits, using field surveys and genomic data.

This study investigates how parent-of-origin gene expression and DNA methylation evolve in the placenta of closely related house mice lineages, identifying tissue-specific patterns and lineage-specific divergence.

This study identifies widespread recombination suppression on the X chromosome of the dwarf hamster, showing it is independent of structural changes and associated with heterochromatin formation.

The paper develops a program to quantify and categorize nuclear morphology in mouse sperm, finding increased shape variability in lab lines compared to wild-derived lines and subtle cross-direction effects in F1 offspring.

The paper develops an automated method to map FISH signals in sperm nuclei and finds conserved chromosome territory organization across mouse lineages.
