The paper examines climatic niche differentiation in the Phyllotis darwini species group, finding low niche overlap and no significant phylogenetic signal in niche differences.

The paper uses mitochondrial DNA sequences to delimit species in Virilastacus, identifying a new candidate species and revising the distribution of existing species.

The paper examines elevational variation in heart mass and RV hypertrophy in Andean leaf-eared mice, finding that suppression of RV hypertrophy is linked to differential gene expression in high-altitude populations.

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.

The paper investigates the diet of Andean leaf-eared mice at extreme elevations using metagenomics, DNA metabarcoding, and stable isotopes, finding evidence of herbivory and potential cryptic vegetation.

The paper sequences 133 Physalia genomes and analyzes citizen-science images to reveal five distinct lineages and four species, with geographic population structure and long-distance dispersal.
