The Ear in Subterranean Rodents Revisited: Cochlear Hair-Cell Populations in African Mole-Rats (Bathyergidae). [PDF]

open access: yesJ Morphol
Morphometric analysis of the cochlea was conducted on 12 species of African mole‐rats (Bathyergidae), revealing that cochlear features related to hearing resolution correlate with body size. Compared to other mammals, bathyergid cochleae resemble the apical, low‐frequency‐tuned regions of typical mammalian cochleae.

Two rodent suborders have evolved missing amino acids in the lipid-binding region of apolipoprotein E. [PDF]

open access: yesLipids
Abstract The order Rodentia comprises nearly 45% of all extant taxa, currently organized into 31 living families, some 450 genera, and roughly 2010 species (Kelt & Patton, 2020). Considering that rodents began evolving at least 66 million years ago, it is not surprising that they have diversified into five distinct suborders.
