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

J 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.

Reproduction, 1981
Summary. Progesterone-binding plasma proteins (PBPP, progesterone-binding globulin, PBG, and corticosteroid binding globulin, CBG) have been measured in plasma of guinea-pigs, casiragua, cuis, degu and plains viscacha. During pregnancy PBPP increased to reach peak values between Days 20–25 and Days 50–term in guinea-pigs, immediately ...
