Journal of Anatomy, Volume 243, Issue 6, Page 910-935, December 2023., 2023 This study uses X‐ray computed tomography (μCT) to three dimensionally reconstruct the bronchial tree of the marsupial Gray short‐tailed opossum (Monodelphis domestica) in order to reveal the timeline of branching morphogenesis. During the postnatal period, the volumes of the lung and bronchial tree steadily increase and development, differentiation ...

Octodon degus kin and social structure [PDF]
Journal of Mammalogy, 2015 AbstractA growing body of evidence showing that individuals of some social species live in non-kin groups suggests kin selection is not required in all species for sociality to evolve. Here, we investigate 2 populations of Octodon degus , a widespread South American rodent that has been shown to form kin and non-kin groups.

Octodon degus: A Model for the Cognitive Impairment Associated with Alzheimer's Disease [PDF]
, 2013 Octodon degus (O. degus) is a diurnal rodent that spontaneously develops several physiopathological conditions, analogous in many cases to those experienced by humans. In light of this, O.

Shaping the development of complex social behavior
Annals of the New York Academy of Sciences, Volume 1530, Issue 1, Page 46-63, December 2023., 2023 Abstract Early life experiences can have an enduring impact on the brain and behavior, with implications for stress reactivity, cognition, and social behavior. In particular, the neural systems that contribute to the expression of social behavior are altered by early life social environments.

Parvovirus-derived endogenous viral elements in two South American rodent genomes [PDF]
, 2014 We describe endogenous viral elements (EVEs) derived from parvoviruses (family <i>Parvoviridae</i>) in the long-tailed chinchilla (<i>Chinchilla lanigera</i>) and degu (<i>Octodon degus</i>) genomes.

Oikos, Volume 2023, Issue 7, July 2023., 2023 Deciphering how climatic variability modulates the interspecific interactions in natural systems is one of the most interesting and least studied ecological processes. Rodent outbreaks or irruptions in semiarid Chile are associated with rainfall pulses driven by the El Niño Southern Oscillation (ENSO).

Communal nesting and kinship in degus (Octodon degus)
Naturwissenschaften, 2004 Communal nesting is a fundamental component of many animal societies. Because the fitness consequences of this behavior vary with the relatedness among nest mates, understanding the kin structure of communally nesting groups is critical to understanding why such groups form.

False alarms and information transmission in grouping animals
Biological Reviews, Volume 98, Issue 3, Page 833-848, June 2023., 2023 ABSTRACT A key benefit of grouping in prey species is access to social information, including information about the presence of predators. Larger groups of prey animals respond both sooner and at greater distances from predators, increasing the likelihood that group members will successfully avoid capture.

Frontiers in Ecology and Evolution, 2021 Seed dispersal is a critical process for plant reproduction and regeneration. Successful recruitment depends on pre- and post-dispersal processes that complete a seed’s journey until becoming a new plant.
