Holocene distribution of Octodontid rodents in central Chile Distribución holocénica de roedores octodóntidos en Chile central

Revista Chilena de Historia Natural, 2003
We describe the Holocene distribution of the Octodontids Aconaemys fuscus, Octodon bridgesi, O. degus, O. lunatus, O. pacificus and Spalacopus cyanus from Central Chile. We compared ancient and present day ranges.

In vivo and contrast-enhanced ex vivo micro-computed tomography for anatomical imaging of Octodon degus

Heliyon
Octodon degus, a rat-sized rodent species endemic to central Chile, can spontaneously develop human-like pathological conditions in captivity. Its relatively long gestation period of ∼90 days provides an opportunity for studies of embryonic development ...

When Raptors Are Away, Opossums Will Play: Woolly Opossums as Carrion Feeders in Harpy Eagle Nests

Biotropica, Volume 57, Issue 6, November 2025.
Scavenging by New World marsupials is rarely documented. We recorded woolly opossums (Caluromys lanatus) scavenging prey remains from a Harpy eagle’s nest in central Brazil. The low overlap in activity periods between the two species may facilitate the behavior observed here.

Skeletogenesis and sequence heterochrony in rodent evolution, with particular emphasis on the African striped mouse, Rhabdomys pumilio (Mammalia) [PDF]

, 2018
Data documenting skeletal development in rodents, the most species-rich ‘order' of mammals, are at present restricted to a few model species, a shortcoming that hinders exploration of the morphological and ecological diversification of the group. In this

Diabetic retinopathy and Alzheimer's disease: Convergence of the unfolded protein response in neurodegeneration

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract Diabetic retinopathy (DR) and Alzheimer's disease (AD) are progressive neurodegenerative disorders affecting the eye and the brain, respectively. Despite targeting different organs, they share common molecular mechanisms. A central process connecting these conditions is the unfolded protein response (UPR), which maintains protein homeostasis ...

Vigilance and Collective Detection of Predators in Degus (Octodon degus)

Ethology, 2006
AbstractIndividuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and other fitness rewarding activities.

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

Degrees of freedom in social bonds of crested macaque females [PDF]

, 2017
Social bonds between group members can affect individual fitness and well-being. While the impact of bond strength is well studied, the consequences of bond predictability and equitability are often overlooked. Similarly, whether bonds reflect short-term
