Androgen Receptors Expression in Pituitary of Male Viscacha in relation to Growth and Reproductive Cycle

International Journal of Endocrinology, Volume 2015, Issue 1, 2015., 2015
The aim of this work was to study the androgen receptors (AR) expression in pituitary pars distalis (PD) of male viscachas in relation to growth and reproductive cycle. AR were detected by immunocytochemistry and quantified by image analysis. Pituitary glands from fetus, immature, prepubertal, and adult viscachas during their reproductive cycle were ...

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 ...
