Genetic Identification of Parasitic Giardia enterica in Three Wild Rodent Species from a Zoological Institution: First Host Records in Brazilian Porcupine (Coendou prehensilis) and Naked Mole Rat (Heterocephalus glaber), and Detection in Crested Porcupine (Hystrix cristata)

Journal of Zoological and Botanical Gardens
Flagellates of the genus Giardia are intestinal parasites with a broad host range. Several Giardia duodenalis variants (assemblages) recently elevated to species rank—G. duodenalis (assemblage A1), G.

Actividad ovárica del tepezcuintle Agouti paca (Rodentia: Agoutidae) en cautiverio

Revista de Biología Tropical, 2006
Se caracterizó la actividad ovárica de A. paca por medio de perfiles hormonales y estructuras ováricas. Se muestrearon ocho hembras (siete adultas y una juvenil) en el criadero de la Facultad de Medicina Veterinaria y Zootecnia en el estado de Yucatán ...

Evolution of the zygomasseteric construction in Rodentia, as revealed by a geometric morphometric analysis of the mandible of Graphiurus (Rodentia, Gliridae)

, 2008
International audienceGraphiurus is a peculiar taxon among the monophyletic Gliridae (order Rodentia) in showing hystricomorphy of the zygomasseteric architecture of the skull [large infraorbital foramen (IOF), and correlative muscular arrangements).

Gastric dilatation and volvulus in a capybara (Hydrochoerus hydrochaeris, Linnaeus, 1766)

Veterinary Record Case Reports, Volume 13, Issue 3, September 2025.
Abstract Gastric torsion has been described in several species, but this is the first documented case in a capybara. An entire, 6‐year‐old, female capybara was found dead in the indoor enclosure of the zoo in the morning. Pathological examinations revealed a large, bloated stomach upon opening the abdominal cavity.

Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

Mammal 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)

Journal 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

Ecology 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

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

Journal 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 ...
