Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

open access: yesMammal Review, Volume 55, Issue 3, July 2025.
ABSTRACT Animals experience seasonal fluctuations of photoperiod, food availability, temperature and precipitation. This affects their energy budget, often leading to seasonal reproduction. We review available literature and (re)‐analyse existing datasets on seasonal reproduction of South American caviomorph rodents that are characterised by long ...

Functional and morphological divergence in the forelimb musculoskeletal system of scratch‐digging subterranean mammals (Rodentia: Bathyergidae)

open access: yesJournal of Anatomy, Volume 245, Issue 3, Page 420-450, September 2024.
The muscles of scratch‐diggers (Bathyergus spp.) show a higher mechanical advantage for forelimb flexion and shoulder stabilization than tooth‐diggers. The glenohumeral and olecranon joints play fundamental roles as robust pivots to resist the action of larger muscles. Tooth‐diggers lacked some muscles aiding with elbow extension and humeral retraction,

Beyond CREA: Evolutionary patterns of non‐allometric shape variation and divergence in a highly allometric clade of murine rodents

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
Rodent skulls display a highly conserved, strongly size‐dependent (allometric) range of shapes that is commonly found across mammals. We here use geometric morphometric analysis of Australian rodent cranial shape to show that this scaling is likely an emergent property of the specialised feeding biomechanics of most rodents, with other non‐size‐related

The myoglobin of rodents Proechimys guairae (casiragua) and Mus musculus (house mouse) [PDF]

open access: yes, 1985
The amino acid sequences of the myoglobins of two rodents, the casiragua and the house mouse, have been determined. The myoglobin of casiragua differs from that of viscacha (another hystricomorph) at 6 positions. Mouse myoglobin differs from that of mole-

Springhares, flying and flightless scaly‐tailed squirrels (Anomaluromorpha, Rodentia) are the squirrely mouse: comparative anatomy of the masticatory musculature and its implications on the evolution of hystricomorphy in rodents

open access: yesJournal of Anatomy, Volume 244, Issue 6, Page 900-928, June 2024.
The digital dissection of the masticatory musculature of (a) Anomalurus, (b) Idiurus, (c) Zenkerella, and (d) Pedetes reveals a great degree of diversity in morphology. These taxa present a hystricomorphous condition of the skull that largely differs from those of other rodents with an enlarged foramen and reaffirms the significance of the descriptive ...

Molecular Evolution of Rodent Insulins [PDF]

open access: yes, 1987
Several trees of amino acid sequences of rodent insulins were derived with the maximum-parsimony procedure. Possible orthologous and paralogous relationships were investigated.

Molecular Cloning and Sequencing of ζ-Crystallin/Quinone Reductase cDNA from Human Liver [PDF]

open access: yes, 1993
Zeta-crystallin is an enzyme-crystallin highly expressed in the lens of some hystricomorph rodents and camels. It has been shown to have a novel NADPH:quinone oxidoreductase activity and is present at enzymatic levels in a variety of tissues from various
