Visual adaptations in a diurnal rodent, Octodon degus
Journal of Comparative Physiology A, 2003The degu (Octodon degus) is a diurnal rodent, native to Chile. Basic features of vision and visual organization in this species were examined in a series of anatomical, electrophysiological and behavioral experiments. The lens of the degu eye selectively absorbs short-wavelength light and shows a progressive increase in optical density as a function of

Nutrition and Behavior of Degus (Octodon degus)
Veterinary Clinics of North America: Exotic Animal Practice, 2009Octodon degus are herbivorous rodents that are adapted anatomically and behaviorally to utilize a fibrous diet with moderate-to-low levels of nonstructural carbohydrate. Captive degus should consume foods containing nutrients comparable to those consumed by free-ranging animals. The species is highly social, demonstrating a broad array of communication

Barnes maze performance of Octodon degus is gender dependent
Behavioural Brain Research, 2010Gender differences in spatial navigation have been widely reported in nocturnal rodent species. Here, for the first time we report gender differences in spatial learning and memory of Octodon degus, a long-lived diurnal hystricomorph rodent. In the present study, 16 months old male and female O.

Cataract Prevention in Diabetic Octodon Degus with Pfizer's Sorbinil
Current Eye Research, 1989The Octodon degus has been reported to have higher aldose reductase activity in the lens compared to the gerbil and rat. When made diabetic the degus develop cataracts within 4 weeks. We have been able to completely prevent cataract formation in diabetic degus using Pfizer's sorbinil for up to 6 months.

Infant-mother recognition in a social rodent (octodon degus).
Journal of Comparative Psychology, 2010Octodon degus (degu), a biparental species with precocious offspring is a potential model for the study of social attachment and related affective disorders such as depression. This study investigates the nature of the social bond between young degus and their mothers with a special emphasis on infant-mother recognition.

Responses to conspecifics' urine by the degu (Octodon degus)
Physiology & Behavior, 1985In nature the degu has been observed to deposit and to investigate scents. This study employed a captive group of these animals to investigate their responses to conspecific urinary marks in a neutral arena. Both sex classes served as subjects. They were presented with urine obtained from males, from females and a saline control. The females were found

Stereotaxic atlas of the brain of Octodon degus
Journal of Morphology, 1992AbstractWe present a stereotaxic atlas of the brain of the trumpet‐tailed rat or degu (Octodon degus), an hystricomorph rodent native to Chile and one which has become increasingly popular as a research animal, among other things because of its use as a model for diabetic catarcts and its tendency to become hyperglycemic.

Isoflurane Anesthesia in the Octodon degus
1989Abstract : Inhalation anesthesia for Octodon degus using isoflurane in a nonrebreathing system is described. Ten laboratory raised degus were used to determine the optimum percentage of isoflurane to maintain surgical anesthesia. Time to loss of righting reflex, time to loss of toepinch reflex, duration of surgical anesthesia and time to standing ...

Ontogeny of homeothermy in Microtus pennsylvanicus and Octodon degus
Comparative Biochemistry and Physiology Part A: Physiology, 1975Abstract 1. The ontogeny of homeothermy in Microtus pennsylvanicus and Octodon degus is investigated through the use of Newton's law of cooling. 2. Temperature differentials achieved at 3 experimental ambient temperatures suggest that threshold effects associated with brown adipose tissue and ontogenetic changes in enzyme system(s) play ...

Common Dental Disorders of the Degu (Octodon Degus)
Journal of Veterinary Dentistry, 2012Dental disease is prevalent in the captive degu (Octodon degus), yet little has been documented on the variety of disorders in this species. In this internet-based study, dental cases presented over a 7-year period were collated, analyzed, and grouped.
