Unique bone microanatomy reveals ancestry of subterranean specializations in mammals. [PDF]

open access: yesEvol Lett, 2022
Abstract Acquiring a subterranean lifestyle entails a substantial shift for many aspects of terrestrial vertebrates’ biology. Although this lifestyle is associated with multiple instances of convergent evolution, the relative success of some subterranean lineages largely remains unexplained.

Multilocus Sequence Typing Unveils Two Novel Genospecies of <i>Borrelia burgdorferi</i> Sensu Lato in Ticks Infesting Cricetid Rodents of Northern Chile. [PDF]

open access: yesTransbound Emerg Dis
Tick‐borne spirochetes of the genus Borrelia are maintained in enzootic transmission cycles involving wild vertebrates such as rodents. The genus includes the lyme disease group (LDG), transmitted by hard ticks (Ixodidae), and the relapsing fever group (RFG), mostly transmitted by soft ticks (Argasidae).

Multimorbidity and animal models. [PDF]

open access: yesAnimal Model Exp Med
Multimorbidity, defined as the coexistence of ≥2 chronic conditions, is associated with aging, genetics, and environmental factors. Animal models in multimorbidity research span three tiers: simple organisms for initial screening → rodents for mechanistic analysis → large mammals for clinical prediction.

Two rodent suborders have evolved missing amino acids in the lipid-binding region of apolipoprotein E. [PDF]

open access: yesLipids
Abstract The order Rodentia comprises nearly 45% of all extant taxa, currently organized into 31 living families, some 450 genera, and roughly 2010 species (Kelt & Patton, 2020). Considering that rodents began evolving at least 66 million years ago, it is not surprising that they have diversified into five distinct suborders.

Octomys mimax (Rodentia: Octodontidae) [PDF]

open access: yesMammalian Species, 2010
Octomys mimax O. Thomas, 1920, the viscacha rat, is a surface-dwelling rodent, endemic to the Monte biome of western Argentina. The genus Octomys is monotypic and represents a basal clade within the family Octodontidae. O. mimax is strictly herbivorous and is found in low-elevation arid environments characterized by galleries or rock formations.

Cytogenetic variation in Ctenomys perrensi (Rodentia, Octodontidae) [PDF]

open access: yesBiological Journal of the Linnean Society, 2000
A chromosomal study that included the use of uniform stain, G-, C-banding and digestion with restriction enzymes Alu I and Sau 3A was completed in 13 male and two female Ctenomys perrensi collected six localities in Corrientes (NE Argentina). The specimens studied had diploid numbers of 50–57 and FN ranging from 84 to 88.

Pitfalls of using sequence databases for heterologous expression studies – a technical review

open access: yesThe Journal of Physiology, Volume 601, Issue 9, Page 1611-1623, 1 May 2023., 2023
Abstract figure legend Projects involving heterologous gene expression are often characterised by similar steps. Initially, database research (A) is necessary to retrieve information of full or partial sequences of a gene of interest. A multitude of genome assemblies are annotated and deposited in public databases or are available for refined search ...

Caviomorphs (Rodentia, Hystricognathi) from Pampa Castillo, Chile: new octodontoid records and biochronological implications

open access: yesPapers in Palaeontology, Volume 9, Issue 1, January/February 2023., 2023
Abstract Caviomorph rodents have been diverse and abundant components of South American mammal communities since the late Eocene. We describe herein the octodontoids of Pampa Castillo, a Lower Miocene site in southern Chile (Aysén Region). Six genera and seven species of octodontoids are present, two of which are new: Dudumus berggreni sp. nov.

Pleistocene glacial and interglacial ecosystems inferred from ancient DNA analyses of permafrost sediments from Batagay megaslump, East Siberia

open access: yesEnvironmental DNA, Volume 4, Issue 6, Page 1265-1283, November 2022., 2022
As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.
