Molecular time estimates for the Lagomorpha diversification. [PDF]

PLoS ONE
Despite their importance as members of the Glires group, lagomorph diversification processes have seldom been studied using molecular data. Notably, only a few phylogenetic studies have included most of the examined lagomorph lineages.

Skeletal indicators of ecological specialization in pika (Mammalia, Ochotonidae) [PDF]

Journal of Morphology, 2013
AbstractCover illustration. Collared pika (Ochotona collaris) is caught mid‐leap on a foraging bout by wildlife photographer Moose Peterson. In this issue of the Journal of Morphology Reese, Lanier, and Sargis study whether postcranial features related to burrowing are present in meadow‐dwelling species and whether talus‐dwelling species (like the one ...

COMPARING THE BODY MASS VARIATIONS IN ENDEMIC INSULAR SPECIES OF THE GENUS PROLAGUS (OCHOTONIDAE, LAGOMORPHA) IN THE PLEISTOCENE OF SARDINIA (ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2016
Prolagus figaro and P. sardus are part of an endemic insular anagenetic lineage that populated Sardinia since the earliest Late Pliocene to Holocene. BM of some populations of these two species was calculated using regression models.

Evolution of CCL16 in Glires (Rodentia and Lagomorpha) shows an unusual random pseudogenization pattern [PDF]

BMC Evolutionary Biology, 2019
Background The C-C motif chemokine ligand 16 (CCL16) is a potent pro-inflammatory chemokine and a chemoattractant for monocytes and lymphocytes. In normal plasma, it is present at high concentrations and elicits its effects on cells by interacting with ...

Factors impacting the complexity of the leporid intracranial joint. [PDF]

J Anat
Anatomy of the intracranial joint and the 2D semi‐landmarks used to capture complexity in the intracranial joint. (a) The intracranial joint can be seen here (in red) between the parietal and occipital dorsally and the basioccipital and basisphenoid ventrally. In hares (as in this figure) the interparietals are fused to obliteration.

The life cycle ofOhbayashinema erbaevae(Nematoda, Heligmosomoidea, Heligmosomidae) inOchotona rufescens rufescens(Ochotonidae) [PDF]

Parasite, 2001
The morphogenesis and the chronology of the life cycle of Ohbayashinema erbaevoe Durette-Desset et al, 2000, a parasite of Ochotona daurica from Buriatia were studied in detail in an experimental host, Ochotona rufescens rufescens. Worm-free pikas were each infected per os with O.

Genomic Vulnerability of a Sentinel Mammal Under Climate Change. [PDF]

Mol Ecol
ABSTRACT Climate change poses a significant threat to biodiversity, particularly in alpine ecosystems where species have already undergone elevational range shifts. Genomics can be used to estimate the adaptive potential of species, as well as the shift in adaptive genomic composition necessary for populations to adjust to climate change (e.g., genomic

Genetic characterization of the chemokine receptor CXCR4 gene in lagomorphs: comparison between the families Ochotonidae and Leporidae [PDF]

International Journal of Immunogenetics, 2008
SummaryChemokines receptors are transmembrane proteins that bind chemokines. Chemokines and their receptors are known to play a crucial role in the immune system and in pathogen entry. There is evidence that myxoma virus, the causative agent of myxomatosis, can use the chemokine receptor CXCR4 to infect cells.
