Early postnatal physical and behavioural development of degus (Octodon degus) [PDF]
Laboratory Animals, 1979 Summary 6 litters of Octodon degus were studied from birth to 10 days of age. Newly-born degus (mean weight 14·6 g) had open eyes, upper and lower pigment, für, and teeth. Within 3–4 hours of birth they were able to walk supporting their full weight, right themselves rapidly, sit upright on their haunches, or rear upright with support, and vocalize ...

A comparison of commercially available feeds for rabbits, guinea pigs, chinchillas and degus with evidence of their diet and feeding behaviour in natural habitats [PDF]
, 2023 A large variety of pet feeds is commercially available for pet herbivores; these feeds may differ in nutrient composition from the natural diet, and may trigger different feeding behaviours than observed in natural habitats.

Binocular vision, the optic chiasm, and their associations with vertebrate motor behavior [PDF]
, 2015 Ipsilateral retinal projections (IRP) in the optic chiasm (OC) vary considerably. Most animal groups possess laterally situated eyes and no or few IRP, but, e.g., cats and primates have frontal eyes and high proportions of IRP. The traditional hypothesis

Prolactin is a strong candidate for the regulation of luteal steroidogenesis in vizcachas (Lagostomus maximus) [PDF]
, 2018 Prolactin (PRL) is essential for the maintenance of the corpora lutea and the production of progesterone (P4) during gestation of mice and rats, which makes it a key factor for their successful reproduction.

Tool use specific adult neurogenesis and synaptogenesis in rodent (Octodon degus) hippocampus. [PDF]
PLoS ONE, 2013 We previously demonstrated that degus (Octodon degus), which are a species of small caviomorph rodents, could be trained to use a T-shaped rake as a hand tool to expand accessible spaces.

Variability of Behavioral Chronotypes of 16 Mammalian Species Under Controlled Conditions [PDF]
, 2016 Human chronotypes (differences in preference for early or late rising each day) have been extensively studied in recent years, but no attempt has been made to compare human chronotypes with the chronotypes of other animal species. We evaluated behavioral
