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

Evol 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]

Transbound 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]

Animal 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]

Lipids
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.

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

The 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

Papers 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

Environmental 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.

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?

Geo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search

Хромосомы и видообразование у туко-туко (Ctenomys, Hystricognathi, Rodentia) [PDF]

, 2016
Tuco-tucos, South American rodents of the genus Ctenomys represent an interesting model of speciation. Their strict territorial and solitary life under the earth, vast but highly fragmented habitats, low migration activity were the causes of their very ...

Genome‐wide adaptive evolution to underground stresses in subterranean mammals: Hypoxia adaption, immunity promotion, and sensory specialization

Ecology and Evolution, Volume 10, Issue 14, Page 7377-7388, July 2020., 2020
We download and evaluate the whole genome of subterranean mammals, and study the mechanisms of adaptative evolution to underground stresses of subterranean mammals through comparative genomics. Abstract Life underground has provided remarkable examples of adaptive evolution in subterranean mammals; however, genome‐wide adaptive evolution to underground
