Molecular Phylogenetics and Taxonomy of the Subgenus Pika (ochotona, Lagomorpha)
A phylogenetic analysis based on partial sequences of 2 mitochondrial genes (cytochrome b and cytochrome c oxidase subunit I) confirmed that Ochotona alpina (Pallas, 1773) and O. turuchanensis Naumov, 1934, are sister taxa to all other Palearctic species of the subgenus Pika. O. hyperborea (Pallas, 1811) contains sufficient genetic heterogeneity to define 2 or 3 races within this species. Exami...
متن کاملThe chromosomes of Tsing-Ling pika, Ochotona huangensis Matschie, 1908 (Lagomorpha, Ochotonidae)
The karyotype of the Tsing-Ling (Huanghe) pika, Ochotona huangensis Matschie, 1908 from the forest habitats of the Qinling Mountains (Shaanxi Province, China) was described for the first time. The chromosome set contains 42 chromosomes (NFa=80). The autosomes are 15 meta-submetacentric pairs and 5 subtelocentric pairs. The X chromosome is a medium sized submetacentric; the Y chromosome is a sma...
متن کاملCharacterization of mitochondrial DNA from the pika (Ochotona rufescens rufescens).
Further to anatomical and physiological studies performed on the pika (Ochotona rufescens rufescens), a new laboratory animal, the main characteristics of the mitochondrial DNA from its liver are defined. The buoyant density of this DNA is 1.695 g/cm3, its length 5.30 mum,, i.e., 3.17 times that of the replicative form of phiX 174. It could have approximately 16 500 base pairs. The DNA from the...
متن کاملOchotona princeps (pika) myoglobin: an appraisal of lagomorph phylogeny.
Myoglobin was purified from skeletal muscle of the pika (Ochotona princeps) and its primary structure was determined. This sequence was added to the set of 64 already known vertebrate myoglobin sequences and used to evaluate the phylogenetic position of the pika among other mammals, using a computerized search procedure based on maximum parsimony criteria. The pika is clearly related to the rab...
متن کاملMolecular cloning and tissue distribution of uncoupling protein 1 (UCP1) in plateau pika (Ochotona dauurica).
Uncoupling protein 1 (UCP1) is present exclusively in brown adipose tissue, and contributes to body temperature control during cold exposure. We cloned UCP1 cDNA of plateau pika (Ochotona dauurica), a small, non-hibernating, diurnal lagomorph that inhabits in relatively cold climates and at high altitudes in Mongolia and in northern China. The nucleotide sequence of pika UCP1 was highly homolog...
