Circadian chronotypes among wild-captured west Andean octodontids

Biological Research, 2006
Rest activity pattern was studied in wild-captured males of Octodon degus (n=9), Octodon bridgesi (n=3), and Spalacopus cyanus (n=6) (Rodentia: Octodontidae). Ten-minute resolution actograms were constructed from data obtained by an automated acquisition

The evolution and variety of RFamide-type neuropeptides: insights from deuterostomian invertebrates [PDF]

, 2014
Five families of neuropeptides that have a C-terminal RFamide motif have been identified in vertebrates: (1) gonadotropin-inhibitory hormone (GnIH), (2) neuropeptide FF (NPFF), (3) pyroglutamylated RFamide peptide (QRFP), (4) prolactin-releasing peptide (

Flight initiation distance is repeatable and geographically flexible in greylag geese Anser anser

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
The decision to flee from an approaching threat represents a trade‐off between the costs and benefits of flight. In research to date, particular interest has been given to the effects of urbanisation on predator escape behaviour. However, these differences are most often studied at the population rather than individual level, which makes it difficult ...

Optimization of inhaled anesthesia for Octodon degus using electroencephalography. [PDF]

Exp Anim
Physiological responses to inhaled anesthetics vary among species. Therefore, a precise anesthetic technique is important for each individual species. In this study, we focused on the degu (Octodon degus), a small herbivorous rodent. Degus have recently begun to be used as laboratory models for brain research because of certain human-like ...

Female home range size is regulated by resource distribution and intraspecific competition: a long-term field study [PDF]

, 2010
The size of an individual’s home range is an important feature, influencing reproduction and survival, but it can vary considerably among both populations and individuals.

The spectral transmission of ocular media suggests ultraviolet sensitivity is widespread among mammals [PDF]

, 2014
Although ultraviolet (UV) sensitivity is widespread among animals it is considered rare in mammals, being restricted to the few species that have a visual pigment maximally sensitive (λmax) below 400 nm.

Revisiting rodent models: Octodon degus as Alzheimer’s disease model? [PDF]

Acta Neuropathologica Communications, 2016
Alzheimer's disease primarily occurs as sporadic disease and is accompanied with vast socio-economic problems. The mandatory basic research relies on robust and reliable disease models to overcome increasing incidence and emerging social challenges. Rodent models are most efficient, versatile, and predominantly used in research.

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,
